Did anyone download the fotos and have his settings? i'm just going by the look of the picture.

#1 - looks like alotta compression as well as very shallow depth of field. Don't know if thats what you wanted it to look.

#2 - is nice, but can become awesome with an off-the camera flash to light the front. You can't really fix this too much with just the camera. You have to understand the compromise between capturing shadow and highlight details. You can't always get both.

#3 - Indoor action shots are hard because you just don't have enough light to even get any shutter speed close enough to stop that dog. You would need 1/250th sec to stop that dog not to mention get it in focus. Low light limits both shutter speed and focus speed. A fast lens will help alot almost 2 stops. Usually a flash will work better for that.

#4 - just too long of exposure. Too much noise appears. And the highlights are gone....

I usually just shoot in P for anything with a tripod then switch accordingly to A or S (Tv). I love digital the histogram and review is awesome. Try learning on film and see how much $$$ you can waste.

Good luck, learning exposure. Also, while at it learn some rules of composition to help your pictures look more pleasing. Rule of thirds, framing, s-curves, ect...They are just guidelines you don't always have to use em.
