This is basically the technique I use when processing my scans. I use the numbers to set both the white & black points to be as neutral as possible, at a certain brightness level. Most of the time that's all the colour correction I need to do, but sometimes I need to make a few more adjustments. This shouldn't be followed religiously: last night I was working on some more sunsets and found that the shadows really did need to be slightly redder than neutral. Sometimes I'll encounter a pic that doesn't have black and/or white points. These ones are usually quite easy for me as minor casts don't seem to be as noticeable if there's nothing neutral, so I'll just look at the slide on the light box (one reason why I hate scanning negs!) and adjust from there. If it all turns to custard, just convert to B&W :) I could waffle on a bit more, but it's nearly dinnertime... - Dave -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
