The art of 3D rendering is an evolving process for any artist. There are tons of programs out there, and some of them are free. However, if you have Photoshop, you can also use this program to create 3D images. In this article, you will learn how to create anaglyph images that are viewed with 3D glasses.
Steps
Part 1 of 3: At the very beginning
Step 1. Take pictures
Take pictures for 3D viewing by shooting the first one, then rotate the camera 3-4 ", right and left, and take the next one. If your pictures are digital, then just open them in the program. If your pictures are in printed form, then transfer them to a computer using a scanner, or give them to a photo studio and ask them to be digitized (any digital format will do).
After downloading the images to your computer, rename the files for easier recognition in the future. Develop a naming scheme for your workflow and use it. For example, images with a left eye might use an “L” in the title, and images with a right eye might use an “R”
Step 2. Purchase 3D viewing equipment
If you succeed, then you will want to look at the work done. You can buy 3D glasses.
Step 3. Create Photoshop Actions
Create template files or Photoshop actions that you will often use to create 3D images. Thus, the process will become more efficient. Since the pictures will be different, each of them will need to be edited separately.
Part 2 of 3: Working with images
Step 1. Open both images in Photoshop
Open the left and right image.
Step 2. Copy the right image to the left one
The right image should be on a separate layer (this is an automatic action).
Step 3. Open the Layer Style menu
Double click on the layer on the right image (by default, it will be named "Layer 1").
Step 4. Uncheck the "R" channel
This option is under the Fill Opacity slider.
Step 5. Click on OK
Step 6. Move the background image
Select the background layer and then using the Pointer tool move the background image to match the focal points of both images. By wearing glasses or using the "Multiply" style, it will be more convenient for you to align the focal points.
Step 7. Crop the image
Crop the image if desired.
Step 8. Save
Save your image and use it!
Part 3 of 3: The Complicated Method
Step 1. Open both images in Photoshop
Once you open the left and right images, convert them to grayscale by clicking on the menu 'Image' - 'mode' - 'grayscale'.
Step 2. Assign a side
Assign the red, green and blue channels to the left eye image by opening the 'Image' menu and choosing 'mode' - 'RGB' (the image will remain gray). Do not repeat this step for the right eye image.
Step 3. Open the Channels menu
You are now ready to blend the left and right image. First, “make sure the left eye image is selected” Open the channels menu “by clicking on the 'Window' menu and choosing 'channels'.
Step 4. Select the blue and green channels
Press the shift key to highlight both channels at the same time.
- Alternatively, you can only use the blue channel instead of blue and green when working with the left eye image.
- Important: only the blue and green channels should be shaded blue.
- At this stage, it does not matter which fields to the left of the channels represent the eyeballs (the eyeballs indicate the mapped channels).
Step 5. Copy the right image to the left one
Go back to the right, select everything (open the 'Select' menu, then press 'all' or Ctrl + A) and copy (open the 'Edit' menu, then press 'copy' or Ctrl + C).
Step 6. Select the RGB color channel
A peephole should appear in the margins of all four channels. At this point, you should see a blurry blue-red image.
Step 7. Tune the red channel
You are almost done. But first, the left and right images need to be aligned. Highlight the red channel in the channels menu (you should see a blue highlight).
Step 8. Configure other channels
The next step is very important, as it allows the red image to be emphasized while the blue remains visible. Click on the RGB channel, eyes should be displayed on all channels.
Step 9. Pick a focal point
Select a point in the center of the picture; for example, if your subject is a person, then the pupils would be a good example for a focal point. Aim at the target by clicking on the magnifying glass icon and clicking on your focus area.
Step 10. Move the images
Select the 'move' tool located in the upper left corner of the toolbar. Using the up and down arrow buttons, align the red picture with the blue so that the color circles become invisible.
Step 11. Reduce the picture
Objects outside of your image should appear in a blue-red halo. In other words, the main goal of this step is to reduce color spread.
Step 12. Crop the image
Trim off excess red and blue around the edges of your image. You can use the crop tool found in the toolbar (after selecting your image, open the 'Image' menu, then click on 'crop').
Step 13. Take a look at your image
Your image is ready for viewing! Put on your 3D glasses (your left eye should be tinted red) and watch your image pop out of the monitor or printed sheet.
