I've also seen tutorials that suggest you create a mask by getting an A channel from the Lab color mode and adjusting it will the Levels and manually, by using a variety of brushes until you have a nice black and white and image which can be used to isolate the background. Boring clicking with the color range eyedropper is the opposite of automatic. Color range selection is NOT a proper way to handle chroma key because we only use chroma key to be able to remove the green color automatically. Why setting the whole green thing up if you're treating it just like any other background? Don't do that. They just say “Use the Select Color Range command” or even “Just click on the background with the Magic Wand”. There are not so many tutorials available for free, and when people discuss the matter, they don't seem to use any advanced methods of isolation. If you google chroma key images isolation, you won't get much help. Keeping the screen as far from your subject as possible helps a bit, but it doesn't eradicate the green fringe.

Dealing with this green spill is really bothersome.

They shot shoes on a white backdrop three meters from the green mannequin and its green background, and almost all the shoes had a green fringe around because of that. I once worked in a studio with a chromakey mannequin stand, and it was casting green reflexes all over the place. Chromakey is notorious for its green spill everywhere. In product photography, we can't just avoid green items and clothes like they do in the movies.Īnd this is not just about green clothes. So, problem number one of the chroma key technology is that it can't really distinguish between the green screen and green items, it just removes it all. But if your model is wearing a green dress, it will get all messed up. What does that mean? We assume that bright green is not a popular color, so we just select the whole range and replace it with white or any other color we need for the background. But don't expect any miracles, because chromakey is basically a color range selection based isolation.

And it also should be smooth, not wrinkled.Īll this will let you use Photoshop to get rid of all the background at once automatically, just like they do it in the movies. It also requires additional light sources, because if your screen is dark green, you won't be able to get rid of it so easily. That requires you to shoot in a big room, and the bigger the room, the higher the rent. It will not just reduce the green spill, it will keep the screen out of focus, too, which also makes isolation somewhat easier. How far should the model be from the screen? At least 1.5, better 3 meters. And if you keep that in mind, setting up a chromakey environment is not as easy as it sounds at first glance. There's more to it than these three rules, but they are the most important.

The screen should be tight, n o wrinkles.

You can isolate bright green easily, but not dark green. The screen has to be bright green, not dark, and your model should not cast any shadows on it.

The screen should be lighted separately with additional sources of light.

Otherwise, you'll get the green spil l al l ove r the model and the clothe s they are wearing.

You r subject has to be placed as fa r fro m the green screen as possible.

Why is that? Well, here's a list of demands that you have to follow if you want to be able to isolate chromakey backgrounds automatically. If you just put a person up against a green screen without proper preparations on stage, you'll get images retouchers will be crying over. The majority of chroma key images I've seen in my life was shot poorly, mostly because people who set the whole thing up didn't realize how complicated this idea was.
