Realistic View Water Reflection

Realistic View Water Reflection

Here I’m going to learn how to easily add a realistic water reflection to your picture.

Here is the photo that I’ll be working with throughout this tutorial:

Realistic View Water Reflection 01

Also you can use your own pictures or find some appropriate pictures thru the Google Images. Ok, now I will explain you how to make the right reflection. In the beginning you should select the part of image what is above the water, then duplicate it and flip vertical. Then we will process copied part of image with some filters to get realistic view water reflection. Ok, using the Polygonal Lasso Tool create selection as was shown on my picture, which you can see below:

Realistic View Water Reflection 02

After that press Ctrl+J to copy selected part of image on the new layer. After that use Edit > Transform > Flip Vertical to flip new copied layer vertical and move it down as on picture below.

Realistic View Water Reflection 03

As you can see the shoreline is rough, that’s why we need to do some correction with it. Use the Eraser Tool to correct it a little bit. But pay your attention that we have some small island from the right side. Don’t remove it from the copied layer.

Realistic View Water Reflection 04

Use the Polygonal Lasso Tool to select this island and press Ctrl+Shift+J to cut selected part of image on the new layer.

Realistic View Water Reflection 05

Now, move it a little bit down and apply Edit > Transform > Warp.

Realistic View Water Reflection 06

Merge this layer with previous again. Before we move to the next step, you need to make displacement map to create the water ripple effect. So, create a new document with the same size. Press D to reset Foreground and Background colors (Foreground color will be black and Background color will be white). Then fill canvas with white color. After that apply Filter > Sketch > Halftone Pattern:

Realistic View Water Reflection 07

Now you have something like this:

Realistic View Water Reflection 08

Save this document as Lines.psd and close it. Go back to our main document and select current layer with Select > Load Selection. After that apply Filter > Distort > Ripple:

Realistic View Water Reflection 09

You can see the result on the picture below:

Realistic View Water Reflection 10

Then apply Filter > Distort > Displace:

Realistic View Water Reflection 11

Click OK in the top right corner of the dialog box, and Photoshop will ask you which file you want to use as your displacement map. Choose the file that you just saved a moment ago (Lines.psd).

Realistic View Water Reflection 12

Now, press Ctrl+T to reduce the height of our reflection and press Enter.

Realistic View Water Reflection 13

Remove selection with Ctrl+D. After that to make reflection at the bottom of the picture more transparent apply Quick Mask Mode with gradient as below:

Realistic View Water Reflection 14

Then go back to Standard Mode. Now we have some selected area, press Delete to clear image in it.

Realistic View Water Reflection 15

Remove selection with Ctrl+D and set up layer opacity to 50%. After that apply Filter > Blur > Motion Blur with similar settings to these:

Realistic View Water Reflection 16

The result should be next:

Realistic View Water Reflection 17

And the last one thing that we should add is ripples. For this effect create a new layer and add a few brush strokes with Brush Tool using white color.

Realistic View Water Reflection 18

After that set up foreground color as #022149 and add more brush strokes on the same layer with this color.

Realistic View Water Reflection 19

After that apply Filter > Blur > Motion Blur:

Realistic View Water Reflection 20

Change layer mode to Soft Light and you will get the final result:

Realistic View Water Reflection 21

On the picture below you can see the final result! I’m sorry but I’m done for now. Please feel free to experiment and you will get the best results!

Ghosting An Image

In this Adobe Photoshop tutorial, we're going to look at a way to give a photo a more "ghostly" appearance.

I'm a fan of horror films, but I admit I'm a bit shallow in that I usually just watch them for the special effects. I'm usually sitting there thinking to myself, "I wonder how they did that". So while playing around in Photoshop one night, I came up with this little technique for taking a living, breathing person and making them appear more like a ghost, which is why I called it"ghosting an image". It's a simple effect with only a few steps involved and they're easy to do.

Of course, as with most photo effects, it helps if you start with the right type of image. A photo of your kids playing at the beach on a summer afternoon may not be the best choice. Then again, you never know till you try it.

Here's the photo I'll be starting with:

The original image

And here's the "ghosting" effect we're after:

The final result

Let's get started.

Step 1: Copy The Background Layer

As always, we never want to work directly on our Background layer, since it contains our original pixel information, so the first thing I'm going to do is copy it. I'm a big fan of naming layers and you should be too, so I'm going to use the keyboard shortcut Ctrl+Alt+J (Win) / Command+Option+J (Mac) to bring up the New Layer dialog box. I'm going to name my Background copy layer desaturated, and we'll see why in a moment:

Photoshop's New Layer dialog box

Photoshop's New Layer dialog box. Name your layer "desaturated".

This gives me a copy of my Background layer in the Layers palette, which Photoshop has named "desaturated":

Copy the Background layer

Step 2: Desaturate The Background Copy Layer

With my "desaturated" layer selected in the Layers palette, I'm going to, you guessed it, desaturate it to remove all the colors. To do that, I'll use the keyboard shortcut Ctrl+Shift+U (Win) / Command+Shift+U (Mac). The image now appears black and white:

Desaturate the Background copy layer

After desaturating the layer, the image appears black and white.

Step 3: Copy The "Desaturated" Layer

I need to make a copy of my "desaturated" layer at this point, so with it selected in the Layers palette, I'll use the keyboard shortcut Ctrl+Alt+J (Win) / Command+Option+J (Mac) once again to bring up the New Layer dialog box. This time, I'll name the layer "motion blur":

Naming my new layer

Create a copy of the "desaturated" layer and this time name it "motion blur".

I now have three layers in my Layers palette, including my new "motion blur" layer at the top:

Three layers now in the Layers palette

The Layers palette now showing my three layers.

Step 4: Apply The Motion Blur Filter

I feel like I'm giving away the endings with my layer names, but oh well. With the "motion blur" layer selected, go up to the Filter menu at the top of the screen, select Blur, and then select Motion Blur. This brings up the "Motion Blur" dialog box. Normally you'd apply a motion blur to an object that's, you know, in motion, but applying it to a stationary object tends to give it a ghost-like effect, which is what we're after. When the dialog box appears, set the Angle to zero degrees, and then drag the slider bar at the bottom to the right to increase the Distance value until your image is blurred out quite a bit. Here I've set mine to 95 pixels:

Photoshop's Motion Blur dialog box

Here's my image after applying the Motion Blur filter:

Step 5: Add A Layer Mask To The "Motion Blur" Layer

Our image already looks a little spooky with the motion blur applied, but now we're going to bring back some of her face, and we're going to do that using a layer mask. With the "motion blur" layer selected, click on the "Add Layer Mask" icon at the bottom of the Layers palette:

Click the Add Layer Mask icon

Click on the "Add Layer Mask" icon at the bottom of the Layers palette.

This adds a layer mask to the "motion blur" layer:

The layer mask added

The layer mask is now added.

Step 6: Paint With Black On The Layer Mask To Reveal Some Of The Face

Grab your Brush tool from the Tools palette, or press B on your keyboard to quickly select it. Then press D on your keyboard to make sure black is selected as your foreground color (Note: If your layer mask was already selected when you pressed "D", your foreground color will actually become white, since white is the default foreground color for a layer mask. If that's the case, simply press X to swap the foreground and background colors, which will set your foreground color to black). Go up to the Options Bar at the top of the screen and lower the opacity of your brush to around 10%:

The Brush tool options in the Options Bar

Lower the opacity of the brush to 10% in the Options Bar.

This will allow you to paint the face back in gradually. Click on the layer mask thumbnail in the Layers palette to select it if it's not already selected (it will have a highlight border around it if it's selected), and then with a large, soft-edged brush and black as your foreground color, paint over the middle area of the face in short, gradual strokes to bring back some of the eyes, nose and mouth, leaving the rest blurred out. Be sure to stay well within the boundaries of the face so everything blurs out nicely from the center:

Paint with black on the layer mask to reveal some of the face

The image after masking away some of the blurring effect.

Step 7: Merge All Of The Layers Onto A New Layer

We're going to merge all three layers onto a new layer at this point, and we can do that with the keyboard shortcut Shift+Ctrl+Alt+E (Win) / Shift+Command+Option+E (Mac), which takes all three layers and merges them onto a brand new layer at the top of the Layers palette. Double-click on the name of the layer and rename it to merged:

Merge all three layers onto a new layer

Merge all three layers onto a new layer at the top of the Layers palette and rename it "merged".

Step 8: Apply The "Diffuse Glow" Filter To The Merged Layer

With the new "merged" layer selected, go up to the Filter menu at the top of the screen, select Distort, and then select Diffuse Glow. This brings up Photoshop's Filter Gallery (it doesn't actually say Filter Gallery anywhere at the moment but it's the Filter Gallery) set to the Diffuse Glow filter options. You may have to play around with the three options a little depending on the image you're using, but for my image, I've set Graininess to 3, Glow Amount to 10, and Clear Amount also to 10 as circled below:

Photoshop's Diffuse Glow filter options

Photoshop's Filter Gallery set to the "Diffuse Glow" filter options.

Here's my image after applying the "Diffuse Glow" filter:

The image after applying Diffuse Glow

Step 9: Add A Solid Color Fill Layer

All that's left to do now is add a little color, so with the "merged" layer still selected, click on the New Fill Or Adjustment Layer icon at the bottom of the Layers palette:

Click the New Fill Or Adjustment Layer icon

Click the New Fill or Adjustment Layer icon at the bottom of the Layers palette.

Select Solid Color from the top of the list:

Select Solid Color

Select "Solid Color" from the list.

This will bring up Photoshop's Color Picker. I'm going to choose a green color:

Photoshop's Color Picker

Photoshop's Color Picker.

Click OK once you've chosen a color to exit out of the Color Picker. You're image will now be filled entirely with the solid color, so we'll fix that next.

Step 10: Change The Blend Mode Of The Fill Layer To "Color" And Lower The Opacity

With the Solid Color fill layer selected, go up to the layer blend mode options in the top left of the Layers palette, click on the down-pointing arrow beside the word "Normal" and change the blend mode to Color. This will colorize the image with the color you've chosen (green in my case). The color will most likely be too intense though, so move over to the right to the Opacity option at the top of the Layers palette and lower the opacity to reduce the intensity. I've lowered mine considerably, all the way down to 11% for just a hint of color:

Change the blend mode to Color and lower the opacity

Change the blend mode of the Solid Color fill layer to "Color" and lower the opacity.

And we're done! Here's the original image once again for comparison:

And here is the final "ghosting" effect:

Photoshop Water Reflection - Add A Realistic Water Reflection

In this Photoshop photo effects tutorial, we're going to learn how to easily add a realistic water reflection to any photo. It's a very easy effect to create and you can add it to any photo you like, although it tends to work best with images that don't already contain water in them.

We'll be using a simple filter and a displacement map to create the water ripple effect, and a Hue/Saturation adjustment layer to give our water a little color.

Here's the photo that I'll be working with throughout this tutorial:

The original photo.
The original image.

And here's what our image is going to look like after adding the water reflection :

The final result.
The final result.

Let's get started.

Step 1: Duplicate The Background Layer

With our image newly opened inside Photoshop, we can see in the Layers palette that we currently have one layer, the Background layer, which contains our image:

Photoshop's Layers palette showing the original image on the Background layer.
The original image on the Background layer in the Layers palette.

We need to duplicate the Background layer, and we can do that using the keyboard shortcut Ctrl+J (Win) / Command+J (Mac). Now when I look in my Layers palette now, I can see that I now have two layers - my original Background layer on the bottom and a new layer, "Layer 1", above it which is my duplicate:

The Layers palette now showing the duplicate Background layer above the original.
Press "Ctrl+J" (Win) / "Command+J" (Mac) to duplicate the Background layer.

Step 2: Add More Canvas Space To The Bottom Of The Document

We're going to add our water reflection below the image, so let's add some canvas space to the bottom of our document to make room for our reflection. To do that, go up to the Image menu at the top of the screen and choose Canvas Size. This will bring up Photoshop's "Canvas Size" dialog box. The easiest thing to do here is to add twice as much canvas space as what we currently have, but we only want it to appear at the bottom of the document, not above it or on either side, so we need to tell Photoshop exactly where we want this extra canvas space to go.

First, enter 100 for the Height and set the measurement to percent, as circled in red below. Leave the Width option set to 0. Then make sure the Relative option is checked, which tells Photoshop to give us 100% more canvas space than what we already have. Below the "Relative" option is a 3x3 grid of squares. This is where we tell Photoshop where we want to place our additional canvas space. Click inside the square in the middle of the top row (again as circled below). This tells Photoshop not to place any of the extra canvas space above the document and instead to place all of it at the bottom:

Photoshop's Canvas Size dialog box.
Add more canvas space using the "Canvas Size" dialog box.

Click OK to exit out of the dialog box, and Photoshop will add the extra canvas space to the bottom of the image:

The extra canvas space has been added to the bottom of the document.. x
The height of the document has now been doubled with the extra canvas space added to the bottom.

Step 3: Flip The Top Layer Vertically

In order to create our reflection, we need to flip our image upside down, so let's do that.

With the top layer selected in the Layers palette, go up to the Edit menu at the top of the screen, choose Transform, and then choose Flip Vertical.

Photoshop will flip the image upside down in the document:

Flipping the image on the top layer vertically.
Go to Edit > Transform > Flip Vertical to flip the image on the top layer upside down.

Step 4: Drag The Flipped Image To The Bottom Of The Document

We need the flipped image to be at the bottom of the document, so grab your Move Tool from the Tools palette, or press V on your keyboard for the shortcut:

Selecting the Move Tool from the Tools palette in Photoshop.
Select the Move Tool.

Then, with the Move Tool selected, click inside the document and drag the flipped image down to the bottom until the top of it is lined up with the bottom of the original image above it. Hold down Shift as you drag to make sure you drag down in a straight line:

The image is now flipped and moved below the original.
Drag the flipped image down below the original.

Step 5: Add A New Blank Layer

Now that we have our flipped image in place, we can begin to create our water ripple effect. First, we need to add a new blank layer at the top of the Layers palette, so with "Layer 1" still selected, click on the New Layer icon at the bottom of the Layers palette:

Clicking the New Layer icon at the bottom of the Layers palette in Photoshop.
Add a new blank layer to the document.

Step 6: Fill The New Layer With White

We're going to fill our new blank layer with white. If white is not currently your Background color, press D on your keyboard, which will reset Photoshop's Foreground and Background colors, making black your Foreground color and white your Background color. Then use the keyboard shortcut Ctrl+Backspace (Win) / Command+Delete (Mac) to fill the new layer with the Background color (white). Your document will be filled with solid white.

The image is now completely filled with white.
The entire image is now filled with white.

Step 7: Apply The "Halftone Pattern" Filter To Create Black And White Horizontal Lines

Go up to the Filter menu at the top of the screen, choose Sketch, and then choose Halftone Pattern. This brings up Photoshop's Filter Gallery (in Photoshop CS and higher) set to the "Halftone Pattern" filter options on the right, with a large preview of the effect on the left. We're going to use this filter to add a series of black and white horizontal lines to the image. These lines are going to become our water ripples . The more lines we have, the more ripples we'll have. First, we want to make sure we're creating lines and not dots or circles, so set the Pattern Type option to Lines. We control the number of lines by adjusting the Size option. Lower values give us more lines, since we're lowering the size of each line, and higher values give us fewer but thicker lines. I'm going to set my Size value to 7, which I think works best for my image. You may want to experiment with this value on your own. The Contrast option below it determines how sharp the edges of the lines are. Lower values give you softer lines, white higher values give you hard edge lines. Set this value all the way to 50 to give your lines sharp edges. We're going to soften them ourselves with the Gaussian Blur filter in a moment:

The Halftone Pattern options.
Adjust the Halftone Pattern filter options to create a series of black and white lines through the image.

Click OK when you're done to exit out of the dialog box, and Photoshop will fill the image from top to bottom with your black and white lines:

The image is now filled from top to bottom with black and white lines.
The image is now filled with black and white horizontal lines.



Step 8: Apply The "Gaussian Blur" Filter To The Lines

Before we can use our black and white lines as water ripples , we need to smooth them out and create nice, smooth transitions between them. To do that, go up to the Filter menu once again, choose Blur, and then choose Gaussian Blur, which brings up the "Gaussian Blur" dialog box. Keep an eye on your image and drag the slider at the bottom of the dialog box to increase the Radius value until the lines have a very soft edge to them. I'm using a small image for this tutorial, so for me, a Radius value of about 4 pixels works well. If you're using a larger, high resolution image, you'll need to set yours to a higher value:

Adjusting the Radius value in the Gaussian Blur dialog box.
Use the Gaussian Blur filter to smooth out the edges of the lines.

Click OK to exit out of the dialog box and apply the blur to the lines.

Step 9: Duplicate The Lines Layer As A New Document

We're going to create a brand new document out of our lines layer, which we'll then use as our displacement map for our water ripples . With the lines layer selected, go up to the Layer menu at the top of the screen and select Duplicate Layer, which brings up the "Duplicate Layer" dialog box. In the "Destination" options, click on the down-pointing arrow to the right of the Document option and set it to New, which will create a new Photoshop document out of our layer:

The Duplicate Layer dialog box in Photoshop.
Set the "Document" option in the "Duplicate Layer" dialog box to "New".

Click OK to exit out of the dialog box, and your layer will open up in a new document on the screen.

Step 10: Save The New Document And Close Out Of It

This new document that we've created is going to become our displacement map, but before we can use it, we need to save it. We're also going to close out of it after we've saved it, since we won't need it open anymore, and the easiest way to accomplish both of those tasks is to simply close out of the document. When you try to close out of it, Photoshop will as you if you want to save the document before closing it. Click Yes:

Choosing to save the document before closing it.
Choose "Yes" when Photoshop asks if you want to save the document before closing it.

Photoshop will bring up the Save As dialog box. You can name your new document anything you like. I'm going to name mine "water-ripples". Make sure you save it as a Photoshop .PSD file, since those are the only files that Photoshop can use as a displacement map. You'll probably want to save the document to your Desktop, since we'll need to find it again in a moment.

Step 11: Delete The Lines Layer

Now that we've used our black and white lines to create the file we'll be using as our displacement map, we can get rid of it. To do that, simply click on it and drag it down onto the Trash Bin icon at the bottom of the Layers palette:

Dragging the lines layer onto the Trash Bin to delete it.
Click and drag the lines layer ("Layer 2") onto the Trash Bin at the bottom of the Layers palette to delete it.

Step 12: Merge The Two Layers Onto A New Layer

Before we can add use our displacement map, we need to merge our two image layers onto a new layer above them. To do that, with "Layer 1" selected, use the keyboard shortcut Shift+Ctrl+Alt+E (Win) / Shift+Command+Option+E (Mac). Nothing will appear to have happened in the document, but if we look in the Layers palette, we can see that both layers have been merged onto a new layer at the top:

Merging both layers onto a new layer in the Layers palette.
Both layers are now merged onto a new layer, "Layer 2".


Step 13: Use The "Displace" Filter To Create The Water Ripples

We're ready to create our water ripples using the displacement map we just created. With the new merged layer selected in the Layers palette, go back up to the Filter menu at the top of the screen, choose Distort and then choose Displace .

This brings up Photoshop's "Displace" filter dialog box. This is where we determine the strength of our ripple effect, and we do that with the Horizontal Scale option at the top. I'm going to set mine to a value of 4, which will give me a realistic ripple effect. You may want to experiment with this value with your own image. Setting it too high though will create too much of a horizontal distortion and you'll lose the realism.

We don't need any vertical distortion to create our effect, so set the Vertical Scale option to 0. Also, make sure that Stretch To Fit and Repeat Edge Pixels are selected:

The Displace filter in Photoshop.
Go to Filter > Distort > Displace to bring up the Displace dialog box.

Click OK in the top right corner of the dialog box, and Photoshop will ask you which file you want to use as your displacement map. Choose the file that you just saved a moment ago, which I saved to my Desktop as "water-ripples.PSD", and then click Open. Photoshop will then apply the displacement map to the entire image, creating our water ripples :

The image after applying the Displace filter.
The image after applying our displacement map with the "Displace" filter.

Step 14: Hide The Ripples On Top With A Layer Mask

Of course, we have a slight problem at the moment. We've added our water ripple effect to the entire image, and we only wanted it in the bottom half. We can fix that easily though using a layer mask. First, Ctrl-click (Win) / Command-click (Mac) directly on the thumbnail for "Layer 1" in the Layers palette to place a selection around the flipped image at the bottom of the document:

Right-click (Win) / Control-click (Mac) on the thumbnail of Layer 1.
"Right-click" (Win) / "Control-click" (Mac) directly on Layer 1's thumbnail in the Layers palette to place a selection around the flipped image.

You'll see a selection appear around the bottom half of the image in your document. Now, with the merged layer still selected, click on the Layer Mask icon at the bottom of the Layers palette:

Clicking on the 'Layer Mask' icon.
Click on the "Layer Mask" icon to add a layer mask to the merged layer at the top of the Layers palette.

Photoshop will add a layer mask to the merged layer, and because we had a selection around the bottom half of our document when we added the layer mask, only the bottom half of the merged layer remains visible. The top half becomes hidden from view, removing the unwanted water ripples from that part of the image:

The ripple effect in the top half of the image is now hidden after applying the layer mask.
The ripple effect is now hidden from the top half of the image after applying the layer mask.

We're almost done. Let's finish things off by adding a hint of color to the water, which we'll do next.

Step 15: Apply The "Gaussian Blur" Filter To The Layer Mask

Before we add our finishing touch by colorizing the water , let's soften the edge of the layer mask a little so there isn't such a harsh dividing line between the image on top and the water below. We'll use the Gaussian Blur filter for that, and since we want to apply it to the layer mask, we'll need to first select the mask. We can do that by clicking on the layer mask thumbnail in the Layers palette:

Clicking on the layer mask thumbnail in the Layers palette in Photoshop.
Adobe Photoshop Tutorials: Click on the layer mask thumbnail in the Layers palette to select the layer mask.

You can tell that the layer mask is now selected by the white highlight box around its thumbnail. We're going to apply the Gaussian Blur filter to the mask, so go back up to the Filter menu, select Blur once again, and then select Gaussian Blur. When the dialog box appears, simply click OK to apply the same Radius value we used previously.

Step 16: Colorize The Water With A Hue/Saturation Adjustment Layer

Let's finish things off now by adding just a hint of blue to our water, and we'll use a Hue/Saturation adjustment layer for that. We want the adjustment layer to only affect the bottom half of the image where the water ripples are, so hold down your Alt (Win) / Option (Mac) key, click on the New Adjustment Layer icon at the bottom of the Layers palette, then select Hue/Saturation from the list of adjustment layers:

Selecting a Hue/Saturation adjustment layer.
Hold down "Alt" (Win) / "Option" (Mac), click on the "New Adjustment Layer" icon, then drag your mouse to "Hue/Saturation" to select it.

By holding down "Alt/Option", this tells Photoshop to bring up the New Layer dialog box before adding the adjustment layer. Select the Use Previous Layer To Create Clipping Mask option by clicking inside the checkbox to the left of it:

The New Layer dialog box in Photoshop.
Select the "Use Previous Layer To Create Clipping Mask" option in the "New Layer" dialog box.

This option tells Photoshop that we want the adjustment layer to affect only the layer directly below it in the Layers palette, and since the layer below it is the layer containing our water ripples , only the water ripples will be colorized, which is what we want. Click OK to exit out of the dialog box.

This will bring up the Hue/Saturation dialog box. We want to colorize our water, so the first thing we want to do here is select the Colorize option in the bottom right corner. Then select the color you want your water to be by dragging the Hue slider at the top. I'm going to drag my slider to the right to a value of about 218, which I think is a good color for my water :

Photoshop's Hue/Saturation dialog box.
Use the Hue/Saturation dialog box to colorize the water .

Click OK to exit out of the dialog box , and you'll see that your water on the bottom has now been colorized, but the color is much too strong at the moment.

Step 17: Lower The Opacity Of The Hue/Saturation Layer

To reduce the intensity of the color we just added to the water , all we need to do is go up to the Opacity option in the top right corner of the Layers palette and lower the opacity value. I'm going to lower mine all the way down to about 25%, which adds a much more realistic amount of color to the water :

Lowering the opacity of the adjustment layer.
Lower the opacity of the adjustment layer until the water has only a hint of color to it.

Once you've lowered the opacity of the adjustment layer to reduce the color intensity of the water , you're done!

Here once again is my original image for comparison:

And here is my final "water reflection" result:

Just for fun, here's another example of the exact same effect applied to a different image. The only thing I changed here was that I only added half as much canvas space below the original image (I set the "Height" value in the Canvas Size dialog box to 50% instead of 100%). Everything else was done exactly the same way:

A second example.
Another example of an image using the same effect.

And there we have it
