Hi again.

I have three cameras:
A Canon 550D, Nikon 800 and a Pentax (something or other).

All have "composite video" outputs via a USB port or otherwise.

Looking at the images on the cameras they are ok but when I view them on e TV, the images on one camera look good/great. Another camera they look horrible.

It was a bit of a concern at first but as I couldn't do much at the time I didn't worry too much.

I got home and looked on the PC and all the images are ok. Or: They bad ones aren't as bad as I thought.

It would seem there is a "problem" with the camera's composite output, or how it displays the picture on the screen.

Yes, it could be the TV as well. Dunno. Haven't tested that side of it yet. Wasn't my TV. Though I may try them on my TV now I am home/back from holidays.

The Pentax one is their waterproof GPS model with MACRO focus down to 1 cm.
