Beautiful photos and interesting technique with the inversion ring for macro photography. I have not heard of it and may have to try it one day.

I'm a little confused - you say you used an EFS 18-55 which is a f/3.5-5.6 if I'm not mistaken, does it come as an f/2 version also? And how do you get to f/1 that you mention under several photos.

This one made me LOL - I consider ISO 800 still quite high i.e. grainy and will use ISO 100 for low noise - guess things change 😆

ISO: Low ISO setting (800) to minimize noise in images.
