>I'm cleaning up some still life images and wondered if there is an easy way of making a light grey background white, without affecting the main object - is it just a case of selecting the object and altering the background in levels / curves or is there a simpler way.
Dear Beckie, I do not normally select the object because I think this always gives you ptoblems with the borders of the object- what I do is in two steps: 1.I go into quickmask mode- use the gradient tool and make a gradient from somewher closo to the corners up to the corners- go out of quickmask and then treat the corners first, also the top and the sides. 2. Then I go into Image- Adjustments- replace colour- here you tick the part you want to get white play around with fuzziness slider- change the saturation to -100 and the change the lightness to +100 You need to play around with this but that's how I cleaned uo 68 portraits the other week- and yes I have learned my lesson again: get it right in the first place with the lighting it saves you time later- but 2 of my background flashes gave up their work during the process... yes the batteries and the fuses...
