First of all, I'd like to thank you for the awesome job you've made with these cheat cards!
I've bought some extension tubes (13mm, 21mm and 31mm) for my Canon 50mm f/1.8 lens, and I was wondering which settings would fit the best for this configuration?
I will mainly shoot human eyes (iris), and so far I've found the following settings:
- Manual mode
- Aperture to f/8, f/11 or f/18
- ISO to 100
Could you enlighten me on the best way achieve that and get an awesome result?
Thanks for your precious help.
PS: My lens in equipped with a circular flash to get better lighting.
