Shadowland

I own an Olympus 7070 which I use in an Ikelite housing with Ikelite strobe. When shooting macro or at least close focus I also use an Inon macro lens. My problem is that I am gwtting shadows in the bottom corner of my shots. Anybody no for sure what the cause of this is and the solution?

Can you please post a photo? When you get dark corners, that is usually called vignetting and it's because the lens is "seeing" the black rim of the lens barrel or the macro lens rim. It doesn't have anything to do w/ your strobe aiming in that case.

Another possibility is that you are getting so close for your macro shots that your strobes are being blocked by the camera housing.

Cheers
