Got Skilz?

I shot a big belly-dancing show last night. There are some skilz I really wish I had practiced up on.

1. How to change the batteries in a flash in near darkness. (give myself a "D" on this one)
2. How to fish out reload and stash the used memory card. ("A" good at this)
3. How to change battery in camera in near darkness ("A" here battery only goes in one way)
4. How to swap lens' in the dark keeping up with both caps with no place to "set" anything.
("D" here, didn't even try to find the front cap)

can you guys think of any more "skilz" you've wished you had while shooting?

Lightroom is exporting the last batch. I'll check them with photoshop and post a couple.

I think it went OK. The sound/light tech was an idiot and when I asked him for more light he raised the house lights a bit. I was shooting really low light. I'll post a couple with details on what I did and ask how the "members" would have done it.
