Takeing Good Pictures:
This is an art. but This can also be a very hard. You could take a Million Shots and none of them come out right. but once you get the perfect shot it is very refreshing. and it feels good that you accomplished something.
A good picture takes, The Right angle to take the picture, the right lighting and the right surcumstances (Not much movment so the camera doesnt move, or the wind moves the item you are photographing) but if you do everything right, it should come out just the way youn like.
Have fun Photgraphing!
