Re: Canon Macro Twin Lite MT-26EX-RT question
While I'm waiting for the Canon Macro Twin Lite to show up, I thought I would explain how I use a macro twin flash. (I'm currently using the Meike version.)
I don't take "true" macro shots of the sort John K discusses using a twin flash. I sometimes delve into that type of photography, but when I do it's with totally different lighting.
I also don't use the twin flash to take photos of small items like jewelry; for that I use a softbox as suggested by danferrin.
I use the twin flash for a specific kind of plant photography, using a technique that was taught to me by an ace naturalist/photographer a few years ago. My goal is to get photos of small plants like tree buds and wildflowers using lighting that throws the background of the photo into almost complete darkness. If I do it right, the result is a photo that doesn't need a lot of postprocessing to look like a "scientific specimen" photo.
First my gear, which includes a Canon EOS M6 Mark II with a Canon EF 100mm f/2.8L IS USM macro attached using a Canon adapter. The Meike twin flash is attached to the end of the lens, of course.
The camera is set to Manual mode. The flash is set to manual at 100% power. The shutter speed is set to the camera's sync speed, which in the case of this camera is 1/200 second. The ISO is set to either 100 or 200. The f/stop is initially set to a really small aperture, like f/22 or even f/32. I take a couple of test shots, adjusting the f/stop as needed for proper exposure.
Here are three examples from a recent outing to photograph early-spring tree buds; hopefully, the EXIF details will survive the upload.
