Lighting is one of the trickiest aspects of macro photography. Using the Lomography Ringflash the way it was intended can improve your macro shots.
At the smallest scales shadows become a problem because a blade of grass might as well be a building. If you try to use a camera’s built-in flash it will be more offset and more useless the closer you get to your subject. If you do manage to light your subject, the flash will often be too strong at macro distances. Macro lenses for high-end cameras can be very expensive, but if you’re lucky you just might be able to use the Ringflash with your macro setup. Many of you know the Ringflash as the ultimate accessory for the Lomography Fisheye cameras, but it was originally designed as a flash for macro photography. Luckily it just happens to fit my macro kit. I have a Canon EOS Rebel Ti and a Quantaray zoom lens with a macro setting. The Ringflash fits perfectly over the rubberized grip on the lens. The Ringflash has a “slave” mode where it will flash in response to another flash going off, so I just set the camera to “forced flash” and fire.
Here are some examples demonstrating the nice, even lighting you can get with a macro flash:
