This was taken last fall with a $40 tripod and a $300-when-new,-probably-$50-then camera:


So these techniques do work for thin branches and twigs!

For macro shots at that close range, a tripod can make a big difference to quality. In this case you’d have wanted the stick laying on the ground and a short (or can-be-and-has-been-made-short) tripod nearby with the camera tilted down to aim at the stick, maybe 10cm between lens and stick, maybe up to 3x zoom.

The other major source of difficulty with a small, elevated subject (like that stick) is the autofocus. It will sometimes latch onto a background feature or something else other than the intended target. If the camera is typical, the shutter button can be depressed half-way to set focus, then held there for a bit, and then depressed fully to take the shot, and then you can fool the autofocus. Put your hand, flat and facing the camera, where the subject will be (if it’s a flower up on its stem, push it forward with your hand until the hand is where the flower prefers to be, for instance) and with your other hand push the shutter button half-way. Wait for the chittering of the autofocus motors to subside. Remove the hand or position the subject where it was. Click. The hand will have filled much or all of the frame during focusing, and the focus is very unlikely to have settled on any other focal depth than where the hand was, which is where the subject now is. Of course, this is difficult to pull off unless you don’t need a third hand to hold the camera in position, which returns us to part one: use a tripod. :)



was taken by using the fool-the-autofocus method described above. A macro shot aimed at them came out with the mushrooms out of focus in favor of the background. I had the camera on a short tripod elevated to the same height as the top of the log with the mushrooms, and about 12cm away. Put one hand on the trigger and one behind the mushrooms; moved that one forward a bit, bending their stems a bit; clicked half-way; removed the hand touching the mushrooms; click; and got the beautiful sharp photograph at that link.

Sorry, cheap camera doesn’t do macro shots too well and they were fairly small. This picture (http://upload.wikimedia.org/...) looks very, very similar except it wasn’t quite as fuzzy.
