All my life with cameras and digital cameras, I've always used auto mode for taking pictures because I could never really figure out if the other features make a difference. Well, recently, I've been taking photos of my paintings. I was forced to explore. What I've learned is that I must do it at very low even lighting and use photo shop to increase the lighting later. With greater light source, the paintings are washed out and no photoshop can fix that and also there's reflection because of the semiglossy nature of the paint. I must put it in a tripod and set a timer so it would remain absolutely still to capture the best resolution possible. I also have it on portrait setting instead of auto (I think that helps. Don't really know). So that turns out pretty well once I fix the brightness with photoshop. It's steady and pretty clear. Not perfect so I look into exposure time. I really don't understand how this work even though I read the manual :b. I thought when you increase exposure time, you get better resolution. Instead, I get a very bright picture. What am I doing wrong? Any comments, advices?
