TG5 and YS-01 : TTL issue

[Searcaigh]

Thanks for sharing..been using their settings but somehow the strobe doesn't works as what been shown on the video...but i guess is 'trial and error' thing for me at the moment

Why don't you drop them an email?

Hi Chris ..yes it does...as i increase the power setting..the image get brighter

I think your best solution is probably trying to use manual flash exposure. Set the camera to Av and f2.8 - 6.3 (it changes as you zoom) set the strobe to manual 1/64 and have your strobe on manual. Adjust the power to get the exposure correct for a subject at average distance which will be maybe 100-200mm with the TG-6. As long as you don't change anything and stay at that distance the exposure should stay the same. If a photo comes out dark it is most likely the strobe is being blocked by something on the reef and you need to re-position it. Try that out for a while before switching to microscope mode. The challenge with microscope mode is positioning the strobe correctly as the subject is often shaded my the housing.

You can do a setup on land, just do it in a dimly lit room so the ambient light is not varying setup on a small toy or something about 100-200mm away adjust your strobe position as suggested in the videos and with settings as above. Take a shot and tweak it till the exposure looks right. That's you starting point to shoot underwater. When you first go in shoot something like a small sponge that's not going to move and adjust till the exposure looks good. Then go on with your dive and pick subjects at about the same distance of 100-200mm for a start. The exposure needed will not change noticeably. Once you get that right slowly expand and adjust as you go. Shoot in Raw as it's easier to correct minor exposure errors.
