onlooker Posted July 23, 2007 Share Posted July 23, 2007 I have a few images of artwork taken under suboptimal conditions. The main problem is that the image is brightest on one side and gets gradually darker as you move towards the other side. Obviously, the original lighting source was off-centered an inadequate. Is there a sensible way to even out the lighting? Thanks. Link to comment Share on other sites More sharing options...
ellis_vener_photography Posted July 23, 2007 Share Posted July 23, 2007 reshoot. It will be less tedious. Link to comment Share on other sites More sharing options...
Matt Laur Posted July 23, 2007 Share Posted July 23, 2007 Clone the image into a new layer. Brighten it. Then use an opacity gradient to make that brighter layer fade away over roughly the same transitional space/rate as the origial image is fading to dark. The original, light -> dark layer should "meet half way" with the new dark -> light layer, and when combined, provide you with a more even look. There are probably 100 other ways to approach this - everyone has their pet method! Link to comment Share on other sites More sharing options...
Matt Laur Posted July 23, 2007 Share Posted July 23, 2007 Um... or do what Ellis says! When re-shooting IS an option, that is. Obviously it frequently isn't, so it's not bad to have this commonly needed post production skill down anyway. Link to comment Share on other sites More sharing options...

david_simonds Posted July 23, 2007 Share Posted July 23, 2007 Larry, If you have CS2 or above, I suggest the shadow/highlight function under Adjustments. I use this all the time to narrow the lighting vagaries in a shot. You may want to create a new layer, then apply the shadow/highlight and then go back with the erase tool to fine tune the effect by removing unwanted addjustment. Hope this helps.

akavalun Posted July 23, 2007 Share Posted July 23, 2007 Do a contrast mask. Copy your background, rename it Contrast Mask, then control-shift-U for desaturate, control-I for invert, then change the blending mode to soft light, filter-blur-gaussian blur to taste, then you change change the opacity of the layer to season to your liking!

ben_moore1 Posted August 2, 2007 Share Posted August 2, 2007 I'd recommend taking Matt's advice, though you can save yourself cloning the layer (which will double your working file size) by using a brightness/contrast adjustment layer. Using a gradient on the layer mask you should be able to blend them easily enough. Link to comment Share on other sites More sharing options...
