Here is another video
showing how to use the red eye removal tool in Photoshop. Quick and easy.
Another method is using the paint brush.
- First duplicate the background layer.
- Zoom into the eye you want to remove the red from.
- Using the eye dropper tool select a part of the iris that still has some colour, outside of the reddish zone. If there is none to sample from, use a neutral grey to neutralize the red.
- Select the brush tool.
- Set the brush size to about the same as the pupil. Maybe 10 pixels. Set hardness to "50%".
- Set the Mode to "color", Opacity "100%", Flow "100%", enable air brush capabilities (it is the icon on the end with the pen and squiggly line).
- Brush over the red area to neutralize the red.
- If you were unable to pick any iris color in Step 3, you may want to add colour to the eye by adding a slight tint of the colour you think the eye should be (i.e., green, blue, brown, etc.) to the grey colour. Do this by double-clicking the foreground colour box. A new menu will pop up where you can adjust the color sliders to the appropriate tint.
- Repeat step 7.
I have attached some preset brushes you can use. Download that attached RAR file and unarchive it and move or copy it to your Drive:/Adobe/Photoshop/Presets/Tools folder. You will then have to add the brushes to your Brush tool presets in PS.
