    I just got some Inon S 2000 strobes for my TG 5. Currently I'm just trying to get one working in macro mode.

    I set the camera up per the Backscatter macro video. Stopped down -2.0, ISO 100, flash on fill in, etc. I have the strobe on STTL to start.

    I've played with adjusting the exposure setting, adjusted strobe compensation on strobe, magnet in, magnet out and the strobe will flash but my image is vastly underexposed. I must be missing something simple. Is there a synchronizing step to make sure the timing of the flash is correct or something?

    Try to set up the system so that you are not at -2EV.

    Correct setting will be magnet out as you have a pre flash from the TG-6 in TTL. If you can't get TTL to work go to manual, the TG-6 allows you to set the flash to manual, have the camera in Av, put the magnet in then take test exposures at f2.8 till the image is correctly exposed. If you are in macro and leave the flash in more or less the same position the required flash exposure should not vary too much. You can do this on land to get a starting point and fine tune in the water.

    Also check you don't have red-eye reduction activated. That gives multiple flashes and will upset the S-2000.

    One thing Backscatter leave out of their video is the fact the TG-6 has only two apertures, f2 and f2.8 (wide) or f4.9 and f6.3 Tele and it has a 3 stop ND filter to achieve f8 (f18 in tele). Going to f8(f18) does not give you extra depth of field, it only reduces the exposure. The only reason to use is to block out ambient light to help get a dark background, that will probably also require the minimum shutter speed setting when in flash to be set to something like 1/250 or higher. If you are at f18 you need a lot of flash power!

    The -2 setting they recommend is on exposure compensation ( not flash exposure compensation) and is recommended to reduce the contribution of ambient light in the image - the light is mostly from the flash, so the exposure is set by adjusting the flash not the camera.

    I would work at f2.8 (or f4.9 as you are shooting macro and will be at the tele end more than likely) to start with until you get that sorted before delving into the min flash speed setting setting as it is buried deep in the menus and also requires auto ISO with the max ISO capped - the lowest you can cap it is ISO400. You could possibly set that up in one of the custom modes with the other custom mode setup for normal flash.
