Re: [Gimp-user] How damaged photos my camera takes?
Others have covered this but maybe I can add a little bit. 3922 (and parts of 3893) can't be fixed in Gimp (or any way image processor) - over exposure means no information was able to be captured - Gimp can't do anything with no information. 3923, because it is underexposed, can be fixed a bit in Gimp. I would suggest using the Levels tool. slide the end pointers to the edge of where the histogram starts to rise. Then slide the middle pointer around until you get some detail in the trees. More importantly - it is much easier to fix when you shoot the photo. Your point-n-shoot has some limitations, but you can work around them with some practice (and manual reading). Here are some more gorey details. Let me know off-list if you need/want more help or explanation. Learn to use your whitebalance. Especially if you are shooting a shot like the flowers with ALL that green. Your best bet would be to (read your manual) set a custom white balance (WB) using that white card of yours. Use this WB as long as the lighting doesn't change. When you go inside and shoot people sitting around those tungsten lights you'll want to change your WB. If you don't want to spend the time to do a custom WB, then pick the appropriate built in WB (daylight, cloudy,...). On a sunny day (daylight) you have all this blue in your photos from the big blue sky, so the camera takes a little blue out of your photo. Also your flash "blew out" the flowers - it made those light blue(?) flowers look white. Turn off your flash. The problem with the other photos is mostly exposure problems. That might be a little bit harder to fix with your particular camera (or any point-n-shoot). In 3922 the meter saw all those dark green trees and tried to make them a nice neutral light grey (all cameras do this) so it let too much light in leading to over exposure and trees that are too bright and a sky that is all white. 3923 has the opposite problem. Saw all that bright blue sky, tried to make it a nice light grey (tried to darken the sky) which it did, so you get a nice dark blue sky, but trees that are too dark and loose all their detail. Your best bet is to either read up on Exposure Compensation (EV Compensation) and AE Lock (Auto Exposure Lock) - especially if you are trying to do panoramas. Also change your metering mode to spot in these cases. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

The pictures aren't really damaged - actually, that's what the "automatic mode" is all about: The camera itself tries to figure out what settings fit best to take an "optimum" shot, optimum in terms of values measurable by a machine. To a machine, determining how the pictures finally will "look like" is a rather tough (not to say impossible) job. If you want to have pictures which look according to your demands or needs, probably you will have to switch off automatic mode and do the job yourself. ;) Cheers, Kristian -- Kristian Rink * http://zimmer428.net * jab: [EMAIL PROTECTED] icq: 48874445 * fon: ++49 176 2447 2771 "Wenn einer allein träumt, ist es nur ein Traum.
