Premium Member Jayson Crothers Posted March 25, 2005 Premium Member Share Posted March 25, 2005 I'm shooting my first HD project soon. I photographed a series of tests the other day and while testing various gain levels, found something interesting that I hope someone could shed some light on. Shooting on an F900/3, I shot at each gain setting, adjusting the lighting to compensate for more/less light. At +12db I noticed a subtle shift in the color of the image, just a bit warmer. At +18 the image leapt to being very biased towards yellow - our vectorscope and HD monitor both confirmed the image suddenly turning yellow. Any explanations? Two other questions: -What's a clockit box? -What advice/thoughts can people offer for shooting 2 HD cameras from a technical stance (my primary concern being sound and TC for each camera - I'm less worried about how this questions affects my work and more concerned with post issues)? Thanks everyone! Link to comment Share on other sites More sharing options...
Premium Member Elhanan Matos Posted March 25, 2005 Premium Member Share Posted March 25, 2005 From my tests I have noticed that +12 and +18 db of gain is very saturated. What I did was desaturate the image about 50% using the saturation page in the paint menus, this looked about right ( I was not using a scope, so I was doing all this by eye) and I tweaked the Video levels until the white balance looked about correct. -What's a clockit box?-What advice/thoughts can people offer for shooting 2 HD cameras from a technical stance (my primary concern being sound and TC for each camera - I'm less worried about how this questions affects my work and more concerned with post issues)? A clockit box is a device that will let you sync up time code between multiple cameras. As for working with multiple cameras, I would recommend you get a DIT.
