Long time ago I optimistically thought a good photographer can use any camera to take good shots. And in a way that is true, but even a damn good photographer can't take good super macro pictures without a super macro lens.
During this year I have planned to focus on using my new mobile phone camera. It provides a pretty good quality. But for someone like me, who has previously used to use full rotating camera display, and remote control display, it really sucks when trying to shoot close to the ground. It is especially difficult when I also would like to point the camera upwards, and not being able to see the display. My recommendation is to get a pocket mirror to use that as a help for aiming.

I think wide angle lens is the best for low angle photography. This is because it much helps to really make it clear the point of view is close to the ground. By following the classic recommendation to have something close to the camera to fill the foreground, and showing the context on the background, it makes the subject obvious.

I also absolutely love using portrait (vertical) composition on this kind of shots because it kind of increases the distance between what is seen on the foreground, and the tiny things on background. This idea works especially well on the "garbage season" series of mine. All kind of garbage people toss away, and drop on the ground, looks enormous when seen through the wide angle lens and from the low angle point of view.
