Not so personal but hope that it's easy to remember. Logo is for my photography trade name website/portfolio. Need it add something?

Excellent. A+ for legibility.
Great! Simple and efficient! Nice choice! Like it but I would kern a bit... The kerning seems to be different for ISO and 100. I would personnaly try those:
1. less space between the "zeros"
2. more space between ISO and 100
3. all the same space-kerning everywhere
