@dkbarnett Hi Delwyn - Thanks for making me feel not so bad about monopolizing people's feeds! This is me first go at the "fireworks" setting on my camera - more fun at the EKKA! It still lets you put in an exposure bias - so I tried a few with a - bias. This was one of them. I think it sort of worked for the low key b&w challenge.
I guess you could say it was low-key since it's only the firework burst for light but I would classify this more as a high-contrast shot (even though there's more dark than light).
Northy is a master of low-key black and white. Check this out- it's an excellent example!
