this color effect iMovie plug-in simulates different kinds of black & white photo paper. you have direct control of the paper's sensitivity to light, making it very easy to achieve some stylistic 'madium' to 'hard' photo paper effects.note: this plug-in is a derivative of our 'quicksilver / rainbow' plug-in. if you already own that plug-in you don't need this one. simply use two colors (black and white), and enable dissolves, and use the 'band' slider to set the simulated sensitivity.
