Flash for Macro Photography

Flash can be extremely helpful. It freezes the subject, because it has a very short flash time and can give a great depth of field when the natural light will not allow it, or a tripod is not possible. It will fire the size of pouch life twice with F16 openings.

There are two ways to use a flash. First fill flash to light when the room is a bit below what you need, and a small flash kind of problem. This is very effective and leaves the background more or less intact

If you need most of the light from a flash, for example indoors or for very small subjects then a slightly different technique applies. With a flash you can set the aperture and shot speed you want and the TTL metering system will sort out a correct exposure for the picture. Except of course the same rules for dark / light subjects apply. The flash has limits to its power though, this is given by its guide number
