I need to get myself a macro lense or macro filter Even with the 300mm (480mm on my DSLR) I can't get close enough to really small things like insects and petals since I have to stand 1.5m away from the object with the 300mm lense.
RAW format is like the negatives in film cameras so you have to process/develop the photo at home. Which mean, you can set things like the whitebalance, reduce noise and increase sharpness and colour space. The thing I like about it the most is that you can increase or decrease the exposure to the photo without damaging the photo or it looking weird like they can if you use try brighten/darken the photo in jpeg format.
It really is the holy grail of photography and you should defiantly try it. The only thing is, RAW format is 2-3 times larger than that of the jpeg or tiff format. I have an 8mp camera so the max resolution is 3456 x 2304 and in jpeg format they're usually around 4-6mb but in RAW format they're around 15mb...
