How to create a 3D image in Photoshop

3D imaging

3D images is a trend that, although it may seem a bit old-fashioned, is still current in the field of photography. Thanks to Photoshop , impressive results can be achieved by converting photos into true 3D images . There are only a few simple steps that we will have to follow to leave the entire audience spellbound with our three-dimensional captures.

To begin, we will have to choose a photo composed of different planes. In addition, these planes must have different textures . For example, we can choose a photo with two people in the foreground, a fountain in the background and a landscape in the background. We must be careful not to choose photos that have many green or red tones so that the 3D effect is well distinguished.

Next, we will open the selected image in Photoshop . To preserve the original photo we will duplicate the layer (CTRL + J). Then we will select everything (CTRL + A) and we will go to the palette where the Channels appear . This palette is in another tab located right next to the "Layers". Within the Channels, we will see that we have four types: RGB, Red, Green and Blue. We select only the Red channel . We will know that it is selected because an eye appears to the left of that channel only.

The next step is to shift the image six pixels to the right . To do this, we look for the “Move” tool, select it, and press the right arrow on the keyboard six times. Afterwards, we activate the RGB Channel again and we will see that the image begins to resemble a three-dimensional one, since the edges of the elements that appear in the photo have been unfolded in red and cyan tones.

However, this effect has been applied to the entire photo and what interests us now is that only the foreground is affected. To erase the effect that we have just applied from the other planes, it is recommended to create a layer with only the foreground of the image and erase the effect from the other planes. During this process we can use the 3D glasses to see better where the effect is not quite right and be able to erase it.

We now move to the background. To create the 3D effect here, it is necessary to follow the same steps that we have followed for the foreground but with only one difference: instead of moving the red channel six pixels, we will move it 4 pixels to the right this time (that is, pressing 4 times on the right arrow of the keyboard with the “Move” tool selected). We erase the effect again in the planes that do not correspond to what we have established as "background. Again, creating a "background" layer will help us a lot in this task.

These steps will be repeated with each plane , the only difference is the displacement pixels that vary in batches of 2. That is, each plane that we add has 2 less pixels of displacement to the right than the previous plane.

It is very important that the different layers are well ordered , the first corresponding to the "foreground", the second to the "background" and so on.

Once this process is finished, we can check if we have done well by putting on 3D glasses , if we are amazed at the result, we have done a good job. It's that simple to create 3D images from simple photographs and amaze our audience with the result.
