概要
Green Screen Studio is a chroma key application that allows the user to change a monochromatic background into any image they wish. Chroma key is a technique for mixing two images or frames together, in which a color from one image is removed (or made transparent), revealing another image behind it. This technique is also referred to as color keying, color-separation overlay, green screen, and blue screen.
Green Screen Studio has tools available to manually remove the background if you do not have a perfect green screen background available. This allows you to manually apply backgrounds to any picture you want without a green screen.
≈ Easy and Simple ≈
◎ Load your background image
◎ Load your foreground image
◎ Manually erase any parts of your foreground image without a green screen
◎ Use the automatic Green Screen feature for your green screen
◎ Zoom in for finer editing
◎ Save your image to finish. You’re done!
≈ Photo Editor EXTRA Features ≈
◎ Intelligent one-tap Auto Enhance filter.
◎ Draw on your photos.
◎ Add fun stickers and text.
◎ Adjust Brightness, Saturation and Contrast.
◎ Sharpen and Blur.
◎ Adjust, Crop, and Rotate your photos.
◎ Red-Eye, Whiten and Blemish tools
◎ Additional ten gorgeous photo effects to apply to your photos.
TIPS:
Green is currently used as a backdrop more than any other color because image sensors in digital video cameras are most sensitive to green. The green camera channel contains the least "noise" and can produce the cleanest key/matte/mask. Additionally, less light is needed to illuminate green, again because of the higher sensitivity to green in image sensors.
The biggest challenge when setting up a green screen is even lighting and the avoidance of shadow, because it is best to have as narrow a color range as possible being replaced. A shadow would present itself as a darker color to the camera and might not register for replacement.
A chroma key subject must not wear clothing similar in color to the chroma key color(s) (unless intentional), because the clothing may be replaced with the background.

レビュー
- レイヤー毎の調整ができないのは致命的 クロマキー合成のアプリとして意欲的なんですが、レイヤーを重ねた状態で独立にサイズや位置調整、ローテーションできないのはこの手のアプリとしては致命的です。
（解説にリサイズとか書いてありますが、あくまで重ねる前か重ねた後の全体が変わるだけです）またバックグラウンドに横長の画像を選ぶと勝手に変形してしまうのも×。
今後の改善に期待します。
- liar! 嘘つき。
- ほとんど と言っていいほど上手く抜けません。ツールもショボい。
