We’ve been struggling with the color on Logitech C920 and C922 webcams recently. (Preparing for a big international conference in November when the cameras will be in around-the-clock use.) Initially each camera had a nice color balance, but after a few days each of them acquired an “underwater” blueish cast, and everything that should have been white in the photo turned a spooky underwater blue!
In part this is due to where we have located our webcams — they’re in rooms with good outdoor light, but no direct sunlight, so the ambient lighting is poor because of all the blue skylight. But the cameras over-emphasized the blue. They were trying to auto-correct, but slewed way too far blue. Instead of compensating for our blue light, they were over-emphasizing it. Today we solved the problem!
