Bought me what must be one of the cheapest but excellent slave flash units ever. It was on sale, no joke, for $7.99 on DailySteals, + $5 shipping. So figure $13 for a remarkable slave flash with side-mount unit. Basically the flash pairs up with the built-in flash on my camera. It bolts to the bottom of the camera where your pod mount connects, and sits about 5" to the right or left of the camera. Syncs to your camera's flash, or can be run on it's own. Adjustable angle, adjustable flash rate. Unbelievable for that price. So, here are my test photos, I personally think they are fabulous and required no touch-ups. Amazing depth, they show off the pockets of translucence, the chatoyance beyond what I was able to pick up through the lens before. I took the macros with the intent of looking "into" the stone. On the micro that I shot, I wanted to see how clearly I could capture those almost microscopic crystal towers around that central stone. I intentionally shot all of these sitting on my oak desk as the background tends to fool the lens, causing all kinds of distortion. You can see that in the micro photos, where closer to the desktop the crystal points tend to go out of focus. Just having fun and enjoying pairing up two of my favorite hobbies....

By the way, the glare you see in the photos is not my flash, it's the stupid desk light, I forgot I was shooting right under it. The paired flash, camera plus slave, is intended to create a ball of light that encompasses the object you're shooting. The smaller flash spot on the photos above, to the right, that is the camera's built-in flash, the staging of the slave flash is set so that it's flash runs a few milliseconds behind the main flash, so you get no glare, but all the light. You see that in the last two photos. That slab is highly polished, with a face like glass, and I turned off my desk light and went macro right to the face of it, and no glare at all! Just amazing for $13... so happy with it....

the same w/ w/o the side flash would have been helpful. hard to evaluate what you used to get when it is not there to see.
the glare is distracting. made the pics look unexceptional. might be worth redoing the experiment w/o the desk lamp and give the comparison shots.
the topic is interesting
