Macro flash

Macro photography is maybe the most fascinating part of photography. It opens your eyes to a world that most people never can see. Taking photographs of small subjects in your house or in the nature, can be a life-long pursuit. DIY Macro flash

Macro photography is very technical, it must be approached correctly or you won’t be happy with the results.

If you are using a typical on-camera flash, the most part of the light will go over the subject,  because this you will need an dedicated macro flash.

This ring flash is perfect for macro photograpy, the light wraps around the subjects as you can see in the images below.

DIY Macro Flash

Compatible with lenses that accept 58mm filters.
I use this macro flash with a Canon 100mm 2.8 macro USM 1:1 +macro extension tubes. The light is strong, enough to be use camera from hand. You can take pictures at 1/100, F6, and ISO 400 f6 in house.
Generated light is much superior to the macro ring with 72 LEDs.
