My video is too bright - what's wrong?
Everything is connected OK, but the video is far
too bright - lighter bits of the image are totally white
If you are using a DA (distribution amp) check
that the termination button is in. If you leave the button out (unterminated)
the video signal will be double its normal amplitude and blow out all the
brighter detail in the image.
Check the settings on the projector - has someone fiddled with the contrast control (contrast = white level)?
If you are using a camera, is the Iris in Manual Iris mode and wide open? Or is there too much gain applied?

This site contains my personal views, ideas, tips, tricks and rants about doing live video, IMAG or graphics at live events on a very low budget. They are published as I get time, in a style closely approximating a weblog. Dave C.

About me
My name is Dave Chalmers and I live in Edinburgh in Scotland, UK. My background is in Electronics, but for 10 years I have been helping to put on live video at events in central Scotland in my spare time. Through the course of these events, nearly all on very constrained budgets, I have learned a few things about what works and what doesn't. While I would not claim to be able to give you all the answers, I can at least help you avoid some of the mistakes.
