Pixel color value

[CharlesH01]

I want to know the colour of each pixel across the photo I have taken.

I am trying to light a wall as evenly lit as possible for photographing large prints. So I want to measure the light distribution as captured by my system. This is complicated by vignetting on the Olympus lens, so I am trying to compensate by extra lighting in the corners.

I have found how to do this in Photoshop Elements, but not in Paintshop Pro. Is there a way?

Thank you for your help. I am trying to work out on which program to concentrate my learning.

PS it took about 10 minutes of frustrated searching to discover that the program help did not recognise colour as a search term. I did buy it in the UK.

Firstly in trying to light a wall as evenly as possible one would use an incident lightmeter. But that was the old way.
Now you would set your camera up on a tripod, photograph the area, move the image to a computer and in PaintShop Pro (or other program) measure the light across your image.
In PSP you can do this with the Dropper tool, under Color Profile use HSL - Hue Saturation Lightness and watch the Lightness value as you move the dropper across the image. You can change the sample size in odd values up to 11 x 11 pixel square. I doubt you would need 1 x 1 pixel as your light source would probably be unable to change the illumination on an area as small as that.

Seems one ought to be able to make a "fake " version:

Promote the background to a layer.
Select the main image.
Select a "Drop Shadow..." 3D Effect.
Make a new layer.
Move the new layer to the bottom.
Do a flood fill.

Now it will look like you have put a drop shadow against a perfectly uniform background.

Edit: Rearranged the steps.

I tried what I suggest:

CharlesH01 How many lights are you planning on using to light the work area ? How large is your work area & how large is the biggest print you plan on photographing ?

I found a product that allegedly produces even light, with no hotspots or falloff on the edges.
