DoubleExposureVideo app for iPhone and iPad

Three easy steps to success:
1. Choose foreground (mask) and background (texture) media files.
2. Adjust either brightness or colour range to determine which mask areas are opaque and which are transparent.
3. Export result.

Basic functions:
Either mask or background may be image or video. So you may achieve very impressive results combining together:
1. Static images for both mask and texture resulting image as destination result.
2. Texture video which which is visible through transparent static mask image areas.
3. Static texture image which is visible through dynamically moving mask video areas.
4. Completely dynamic picture as texture video which is visible through also moving mask video areas.

Features:
1. You may use brightness and (or) chroma key settings simultaneously for mask transparency area determination.
2. You may set opaque mask areas transparency with opacity slider to achieve blending effect.
3. You may also achieve smooth opaque-to-transparent curve with special smoothness slider.
