There are a could of styles that would make sense to add to the BUILDING BLOCKS>GENERATORS>LIGHT EFFECTS section. Some of the more modern Image Light Manipulations include:
- Adaptive Exposure (link)
- Adaptive Saturation (a program that uses this link)
- Mid-Tones (adjust)
- Shadows (adjust)
- Highlights (adjust)
- Details (enhancement)
These (as seperate STYLE boxes) would allow for adjusting the exposure at varying levels of darkness... this is much more than the simple "Brightness" and "Contrast"... these effects would allow for some HDR (high dynamic range) effects.
