PHP gdlib or imagemagick lighting normalization between 2 images -

is there simple way (tool, script) to, having 2 images of same scene in different lighting conditions, normalize them appear made in same conditions?

i have read histograms , how normalization should work, can't find real (non theoretical) solution.

is there simple way ... (non theoretical) solution?

there's plenty of implementations out there, ones patented, , under lock-n-key companies fuji, nikon, polaroid, & etc.

your going have math, and/or mimic other opensource works.

php's imagick offers methods imagick::contraststretchimage, , imagick::linearstretchimage align, trim, , shift histograms. if attempting adjust lumanuis, imagick::colormatriximage can used rebuild/alter image's color-balance. take @ fred's whitebalance script example.
