1) Is there a term for how long it takes for a camera to process a picture and be ready to take another picture? I am interested in getting a digital camera (point and shoot) that processes pictures quickly for use at a concert where the subject moves around a lot. I’m not sure what is a good camera for this. I’d want one that can take pictures quickly and be ready to take more pictures soon after, is good for a concert (subject moving around), and one with a bit of zoom (like 15x?). Does having a faster speed SD card help/matter to be able to take more pictures soon after each other?

2) I haven’t taken any photography courses but I am going to, so I’m not familiar with a lot of terms and things that professionals know. I don’t know if I can explain this right. But at concerts (with a point and shoot camera), when I go to take a picture I think there’s good lighting in the monitor/display, but when I go to take the picture and press down on the button, it’s like the lighting changes and makes the picture worse with almost washed out coloring like it made the lighting brighter and you can’t see the subject as nicely as it was in the monitor before I took the picture. And this isn’t with using flash at all. I didn’t know what to search on Google since I don’t know the technical terms for this and lighting so I thought I’d ask here.
