know your camera

I own a Cannon powershot SD1200. it has 10.0 megapixals 4x optical zoom and 16x digital zoom. Some things that i learned about it is that it is easy to use but takes a good enough pitcure. Optical zoom doesnt distort as much as digital zoom. The camera can change the lighting by a great ammount. Shutter speed blurs the photo. Flash makes things look flatter. In display mode it can show me the light sources. Image stablizers dont work as well as they are hyped up to be. macro works well for upclose images. infinity setting works well for long range/ landscapes. and portrait works well for taking pictures of people. What format of pictures does it take? How can one make objects seem more normal? How can one get sun spots out of the image?
