Lens "shadow" from housing...

[sbloomer]

Hi all

I was just wondering if there was any quick-n-dirty way to get around the lens shadow when using the flash with my Canon S1 and it's housing. The flash works well in macro shots, but it's all spoiled by the darker arc in the bottom of the picture. I know the ideal is a external strobe, but finances are limited (I need to pay for my Pemba trip).

Any ideas?

Hi, Simon,

I had the same problem (and same camera)... I tried tilting the camera to get rid of the shadow but it doesn't away work. In the end I gave up and bought a strobe

If anyone has a solution, I would be interested to find out too!

Another trick I used before I bought the strobe was ... since this problem is only with macro shots and I know that the shadow is always on the lower one-third, I would focus the subject in the upper 2/3 area... and then crop the pictures later on.

Yeah, that's what I thought of doing in future if I need the flash...

I have a Canon Powershot G5 in an ikelite housing. I find that sometimes I need to zoom in a little to prevent the shadow from forming while using an internal flash. something about zooming in a little causes the lens to physically extend just far enough so the the shadow does not show in the picture.

But as others have said, the real solutionis an external flash.

I had that problem with my Canon A40, and noticed that it went away if I went to 3x optical zoom. The lens extends out to near the boundary of the housing, and the shadow goes away.

The shadow is the lens blocking the flash.. You could try not using the flash (available light) - you will probably have to increase ISO though. A powerful (HID) torch will help - but costs more than a reasonable flash... As others have mentioned, you can also zoom in or crop it out.
