gradient in the associated mask with the gradient tool. You can use the
color sampler tool to measure the brightness values in the same point in
the neighboring image. Once you found good values record the whole
process as an action and create a droplet from it. You then can drop all
your 400 files on it and let the computer process them while you do
You can even use a flat field: shoot an evenly lit surface with same
aperture and exposure settings (you can rotate the camera, shoot several
and average later). Do an auto levels on the resulting image and use the
result as a mask. To find the correct adjustment try on the original
image until lighting is perfectly even. To see this better you can put
an auto levels layer above.
