Hello. I really need a help! I had a photo shoot at indoor pool and
I had problems overexposing using ikelite strobe using AV mode. Wanted to switch manual on my Canon 50d
to stay with 1/250 and down the Fstops but it didn't let me. I can control the setting out side the housing but
when I put it in the housing, it doesn't let me control. What happened? What am I doing wrong?

- It never over exposed with ikelite strobe using AV mode before and now it does.

- I never had a problem controlling manual mode with ikelite housing but now it does.

Could you help me what I'm doing wrong, please? Or how I can fix it?
Thank you so so much!

You probably have one of the control arms slightly maintaining pressure on one of your "active " control buttons on your SLR. Active controls are those that will lock out other functions when they are activated (such as preveiw, ev control, or ISO setting. take tha camera body out, turn EVERY control arm so that is ain a new position that is farther away form the camera body, then re-insert the camera body. Hope this helps!

Watch the direction you are shooting. Some times in the pool, the light will bounce all around and over expose. Take one of your over images and crop every thing away except the subject and then look at the reduced image's histogram!
