General Tips

1.You should completely assemble and test your set-up in a swimming pool before using it in open water.

2.It is a good idea to start each photo dive with a fully charged battery(s) in the camera and strobes.

3.As soon as you enter the water, take a moment and check the housing to see that it is properly sealed.

4.Next, check to see if there are any bubbles on the face of the port. If there are, take your finger and remove them. If there are bubbles on the lens port they can produce soft focus spots in your photographs.

5.Set Image Resolution to the Highest JPG format available or RAW. Higher resolution settings are required for printing. High resolution images can easily be reduced in size with software and retain their original quality. A Low resolution image can be enlarged with software but much of the quality will be lost.

6.Digital images are usually transferred to the computer where their appearance can be fine tuned. Many of the image manipulation programs make you think you can magically correct any image taken and make a good picture. One thing to be aware of is that if an image is overexposed that some of the color information in the file is missing. If the color is missing you cannot adjust it. If images are underexposed the color and detail may be there, it is just dark, and you can adjust it to some degree. So if you error in exposure it is better to have the image slightly underexposed than overexposed.
