Giới Thiệu · Brightness Equalizer
Brightness equalizer is an iMovie plug-in that lets you exert photoshop-level control over brightness in your clips. It works similar to brightness curve adjust, except that instead of setting in/out values absolutely, you set them relatively (like in an audio equalizer).A pixel's brightness is determined by itâ??s composition of red, green, and blue values. A perfect digital image has a linear brightness range running straight from zero to 255. However, most devices (and especially photo paper) do not perceive everything perfectly. The straight line becomes distorted. this plug can either distort or repair a clipâ??s brightness curve. Brightness curve adjust sports one 256 band equalizer for individual brightness control, plus individual pre-set and calculation routines (plus the ability to load from or save your pre-sets to disk)
Note:
Brightness curve adjust is more powerful, but less intuitive to use than brightness equalizer. If your main goal is to adjust a digital clip to normal film media brightness behavior, you should use this plug. If you need more power, try brightness curve adjust. If you need even more power, try RGB curve adjust.
