for #2 you only need to match the lowest number. so if R is the lowest of the three, you adjust G and B so the value will match R.

ah this should be better. i was in a hurry explaining earlier. in levels, to get to the colour channels just click on the RGB. or ctrl + 1 = red, ctrl + 2 = green, ctrl + 3 = blue.

you gotta adjust 2 colour channels and you use the highest number in 1 as a guide and the lowest number in 2 as a guide.

so say #1 is:
R: 135/135
B: 201/201
B: 174/174

you need to adjust the R and B to 201

in PS, go to window and open the info window
in the tools bar select color sampler tool (that's the one in the eyedropper, just click and hold and move to the color sampler)
set sample size (top left) to 5 by 5 average
on the photo click on where you assume is white
then click on where you assume is black
you should have 2 targets on the photo now
open levels, image>adjustments>level
now look at your info box at RGB #1 and RGB #2
it should read something like RGB #1 R:133/133 G:183/183 B:235/235 (these #s are only example, you'll get different values)
now on the levels go to red channel and drag the right arrow on the input value to the left until the number on the info for the R: matches the highest number on the #1, so in my case i have to set the red input level to 144 so the R on #1 matches 235, and G input would be 198, leave B alone since that's the highest value

now you have to do the opposite for #2, it's just that you have to use the lowest value. my sample reads on the info window #2 R:7/7 G:9/9 B:14/14

so that means i gotta drag the left arrow on the blue channel over to the right until the number matches 7. same for G.

this should get you in the ball park. from there you can make more adjustments if you feel needed. it's pretty confusing, easier if i was sitting there showing you.

(so I don't have to painfully re-do every pic) Thanks again JZ, I learned a lot from this/you, as usual.
