I built a video tutorial for doing low-key macro photography using the Olympus Tough TG4 or TG5. It’s suprisingly easy to do when you see somebody else do it.
One huge warning: dive torches usually heat up and can burn out the bulb when you use them outside of the water. They need to be in the water to cool them down.
Feel free to play with the angle of the torch and distance from the torch to the subject. In general, the closer you are to the subject, the brighter it will be and the darker the background will be. You’ll also have to deal with shadows and transparency when you do low-key because you’re lighting from one direction.
A huge thanks to Pikachu for sitting still during the modeling session.
See You Underwater
