white balance (2 replies)
which is the correct way of using white balance?
constantly placing a wb for day and night or adjust during each shot?
i hope this video will help you to understand what you really need to .
More the first than the second. Remember that narrative movies and TV shows are color-corrected after they are edited so it is more important to be consistent within a sequence / scene than to have every shot with its own white balance set in camera, that way if the whole edited sequence needs to be shifted some direction in color, it goes faster for the colorist than if every shot has its own unique bias.
You’d think that by white balancing every shot you’d be more consistent but you’re forgetting that sequences are edited so it is only when you see it flow as a scene and see shots juxtaposed against each other that you really get a sense of the color shifts between them. So you set the color balance in camera for the scene, not each shot, then you try and be consistent in exposure and lighting within the scene as you shoot the coverage.
As for whether for the scene you use a preset color temp setting like 3200K or 5600K, or a color temp setting other than those two values, and whether or not you adjust the tint (green/magenta axis), or whether you actually use auto white balance by pointing into a white or grey card and then lock it, it just depends on what makes sense for the location and lighting. I’d say though that using auto white balance is pretty rare if your camera allows you to fine-tune color temp and the green/magenta levels.
