Experimenting with digital backgrounds.

this looks great.. the shot is good and the background really looks natural, well not exactly natural, but you know what i mean..

Congrats on a job well done! What is your method of extracting your subject from the background? Was the original background busy or was it all one color? I am in the middle of trying to learn this method.It's difficult!

Great job. I am just starting to play around with layers, swapping backgrounds, etc.. You are obviously far more accomplished than I at extracting subjects and creating composite photos.

well. to be honest excellent look..... at this range there is just one point (at the back of the hair) where some bluring can be seen and among that like it is shot without *digital background asembling.


hope to see more

regards Zak

Excellent job! What background color did you shoot her on? Did you use a plugin to create the mask or did you cut her out yourself?

style="BACKGROUND-COLOR: #000000"I've been using Digital Anarchy's Primatte plugin and a greenscreen for this purpose. It works rather well, but requires a *lot* of detail postwork to remove the reflected green light and fringing.

The background was black and I extracted her in photoshop. I tried to the Digital Anarchy demo and could not make myself like it.

I have not tried using a green or blue screen yet but I plan on getting some soon.

Based on your result here, I'm thinking black background is the way to go. How long did it take you to process out the background? How did you achieve such perfect seperation with her individual hairs? I'm trying to see if this would be a better solution than what I am currently doing.

Black background worked so well because there is no black on the model. Different backgrounds work better for different people, depending on skin and hair color, and also for different types of clothing.
Green screen works better for light-skinned and light-haired people, and blue screen tends to work better for dark-skinned and dark-haired people. However, that rule of thumb is for video. In a single still frame, it doesn't apply as much if you light the subject correctly. The important thing is to select a color that is not in the subject. This is pretty easy since, with even lighting, the range of colors that you remove can be very small.

Hope that helped!

I understand -- I've already used chroma-keying with video quite a lot, and just now am starting to use it in still photography. The black background also worked well because with a colored backdrop (say greenscreen) the fine details of the outline of the subject (such as individual hairs) will be prone to have green fringing. Most methods of automatically removing it result in a lot of lost sharpness/detail so the best way is still by hand, at least that I've found. The black background worked so well because the fringe is instead black -- which results in a slightly darker halo but of the same hue, where a colored screen produces a colored halo. The darker halo is a lot less noticable, if it is even visible at all.

Of course there is no solution for every situation, but this image proves to me that a black backdrop is definately preferrable if the situation allows.
