Often the stereoscopic effect is created with the help of unusual tricks of the photographer, but today we will achieve it by editing a ready-made photo. The first part of the article describes how to make a simple 3D photo, even a beginner can handle it. The second part is for more professional users, it will tell you how to make the picture more lively.

Part One. For beginners: simple 3D effect

There is a special technique for making 3D images — anaglyph, which usually consists in taking an object from different points and then combining the images. But today we will achieve the same effect using the color channels of photography. Open a suitable photo, let's get started.

channels in photoshop

You can use any image, but you definitely need to switch to RGB Color mode. If you are in Grayscale, Indexed Color or CMYK mode, then you need to switch to RGB (Photoshop: Image > Mode > RGB Color).

Note: This method is suitable for those image editors that allow you to mess with color channels, for example, Photoshop or GIMP. Photoshop Elements and Paint.NET do not allow to use this method of photo editing.

photoshop editor

First, make several copies of the photo (left screenshot). The easiest way to do this is to right—click on the "Background Layer" and click "Duplicate Layer". After making 2 copies, select the top one and go to the channel panel. You can see it by clicking Window > Channels. In the channel panel, select Red channel, as shown in the right screenshot.

photoshop canvas

Press Ctrl+A (in both Photoshop and GIMP) to select the entire canvas completely. The photo should turn out in gray tones, if your photo looks like in the picture, then you are moving in the right direction.

Press V to select Move Tool (in GIMP, press M), and move the red channel layer to the left, as shown in the figure.

GIMP has similar tools in Toolbox, almost like in Photoshop.

In Photoshop CS5, the keyboard shortcut Ctrl+2 will return you to RGB mode. In other versions, just go back to the layers panel and select the new active layer. You can stop there, since you have already received a decent 3D image, but you can work a little more and add depth to it.

Part Two. Add depth to your photo

At this stage you should have several copies of your original photo, let's go back to the top layer in which we created the 3D effect.

how to add depth to a 3D photo

Create a mask as shown in the screenshot on the right by selecting a layer and clicking on the button at the top of the layers panel. In GIMP, right-click on the layer and select "Add Layer Mask" and "White for Full Opacity".

Use soft brush to mask some areas in the top layer. The goal is to return part of the background to its original appearance.

photos with 3D effect

Here are the before and after photos. In a layer with a 3D effect, the background is from a layer without a 3D effect.

In the picture you can see what the mask looks like.

Now go to the lowest layer and edit it. Let's choose the red channel for this layer.

And now we will perform similar actions. Select the entire canvas (Ctrl+A), but apply a slightly different effect to the background.

Use Ctrl+T to select the "Free Transform" function. And freely change the layer of the red channel. You can distort, zoom in, rotate, in general, you need to make the foreground and background different from each other.

In GIMP, this tool is called the "Scale Tool", keyboard shortcuts: Shift + T.
