Photoshop for All: RE: [photoshop-beginners] Create a grey card in Photoshop

That is essentially what I do, if you don’t adjust the saturation down a bit the result could be dulled colors which is the purpose of adjusting the saturation of the ‘neutral’ color from the ‘average blur’ step. Using only a small section will allow you to see the results to ensure you get the results you want. Both methods work though.

Here is probably the fastest, with the least effort, method I have come across for dealing with color casts:

# With the image open duplicate the background and make the duplicate layer the active layer.

# Go Filter > Blur > Average. This filter averages all the color in the image and changes the image to show this averaged color. This color should be a neutral gray. To make it neutral,

# Add a Levels Adjustment layer.

# Click in the image with the middle eyedropper, the midtone eyedropper.

# This adjusts the tones on this layer to neutral gray. Click OK

# In the Layers palette click the eye next to the background copy layer (now adjusted to be gray) to turn if off or hide it.

# The Levels adjustment layers adjusts all layers under it so the adjustments you set to neutralize the background copy layer will be applied to the background, effectively neutralizing the midtones.

# The image should now look color correct.

This method was presented by Tim Grey, he had an earlier method that took a few more steps.

I have put together a short tutorial on creating a ‘grey card’ in Photoshop. This will allow you to set a custom grey point (correct a colorcast).
