Testing gear on land vs water - what considerations?

[smoore]

One other thing to check on strobes is that they are firing in sync with your camera. This camera does not appear to have a manual flash mode so you need to set the camera flash to fill and the strobe to TTL mode. Take test shots into a mirror and you should see the flash clearly firing in the pictures. If it is not is firing but you cannot see the flash in your pictures, then you likely have do not have the proper settings for the strobe's mode. It is good idea to test this on land because when you suddenly get dark pictures you may not realise what is wrong underwater.

The main thing is get familiar with using the camera. Try to use manual settings as much as possible. Once you figure out how to shoot in manual, then put it in the housing and learn where the buttons are on the housing, they are not always the same as on the camera.

You may be forced to work by feel and memory in the water, especially if you are over 40. You can glance at the display and histogram to have an idea of exposure, then start making adjustments. If you are shooting in raw, you will have a fair amount of leeway in exposure and color correction vs in camera image processing.
