Amaryllis
I’ve been experimenting with macro shots or portraits that have a black background. For this I reduce the roomlight with the help of the electric shutters, the exposure time and the ISO value are increased. To improve the quality of the shots, I also used the method of frame averaging to get the RAW image with a single shot and sufficient quality.
Yesterday I was able to admire my friend Harold in a tutorial how he created LowKey HDR macro photographs using an exposure series from -4 EV to 0 EV. I tried all paths today with my Amaryllis, which I had bought 2 days ago.
The exposure series can be performed for LowKey pictures and HighKey pictures. Through the systematic under-exposure one can create a beautiful black background. The use of a surface spotlight creates transparencies with HighKey effect.
The LED lightbox can be placed vertically on the wall. With two clamps you attach the black velvet as a background and loosen the clamp gently to create the HighKey image after switching on the lightbox.
A series of exposures with 5 shots between -4 EV and 0 EV is sufficient to capture the set in high quality.

I like to make things visible the naked eye isn't able to see. That's part of my profession as a radiologist, too.
