Macro without TTL

I've never shot macro without TTL. Today I connected my sea and sea TTL converter to my D300 to check it for a dive trip in 10 days to Bonaire. The converter won't fire the strobes even in manual so I'm going to shoot all manual this trip. I have two Sea & Sea YS-120 strobes. The only control on these is 1/2 power and full power. It seems a lot of you shoot macro without TTL all the time. Any advice would be greatly appreciated.

I have that same combon, YS 120 strobes, no TTL. Leave it on 1/2 power. You will find most of your shots will come between f14-f22 or so... just check your shots and the histogram on a regular basis to dial in the right fstop. The further you are from your subject the more "open" the aperture needs to be

A lot of the time I use just one strobe in order to create interesting shadows, you may want to give that a try

OK, thanks. I'll start there.
