Does anyone have a problem with auto-gain and their webcam -- I was wondering if Steph or anyone else had a problem with a quickcam and the auto-gain going spaz (or simply not working).

Webcam's and auto-gain
This is possibly the best first-time post ever. So many layers. :lol:
I know nothing about webcams, and I'm not even sure that I know what auto-gain is, but I'll restrain every grammar-nazi fiber of my being and simply say WELCOME TO THE NUTHOUSE!!
I turn the auto-gain (and auto-everything else) off on my cam. It means I have to tweak it occasionally if I have it on for a long time (sunlight though the window disappears), but I find that I don't get the weird changes from really bright to really dark depending on which part of the frame my white shirt is in.
*sheepish look* thanks for welcoming me everyone :)
Blaze - the issue I have is the webcam is pointing at the back yard where the pugs play, so I go from early morning light to full day light to twilight - I think with fixed settings, only about 4hrs of that (out of say, 12hrs) is a decent image. I think if I can find where the settings for the camera are stored, I could write a service (or scheduled task if I were lazy) to apply a "early morning", "day time" and "twilight" settings selection..
thanks :)
Ah. I see.
Dealing with "outside" is really tricky with a webcam, as most of them are designed with indoor, consistent-lighting, types of situations, and the gain is just to deal with shadows and light-clothing vs. dark clothing.
I don't know enough about the workings of the drivers to suggest how to manipulated them in the way you suggested.
Depending on your needs (and your money situation), you may want to take a look at an indoor/outdoor network cam--something that's designed to deal with changes in daylight.
