Hello all
One of the characteristics of vertical aerial photography is a tendency for uneven exposure – even the latest million dollar + capture systems exhibit this problem. When you use 1000’s of these images to produce products you can end up with a striped appearance – not good. So along with other (IMO less successful) software tools we use Photoshop to try to address this issue. So far adding a neutral density gradient mask (layer) to the image helps a lot to even overall density. But when this initial unevenness also includes a loss of contrast on the light side you end up with an ‘even’ image that’s contrasty on one end and flat on the other.
So without adding a bunch of screen shots (right now at least) tell me if this can be done:
Image A is good contrast / brightness on left half, light and flat on right. Make image A copy layer. Adjust A copy so that right side ‘matches’ left side of A original. Create a new layer with a ND gradient that approximates what you want to keep/delete (doesn’t matter at this point) and use that as a ‘template’ (not sure if that’s the right word) to modify the image A copy. Like a layer mask?
Oh, one more thing - this needs to 'batchable'
Thanks!
