what is it?
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 it’s composition of red, green, and blue values. a perfect digital image has a linear brightness range running straight from zero (darkest) to 255 (brightest). however, most devices (and especially photo paper) do not exhibit linear properties when recording images. the straight line becomes distorted. this plug-in can either distort or repair a clip’s brightness curve.
brightness curve adjust sports a 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)
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 the curve adjust. if you need even more power, try rgb curve adjust.
what should i use it for?
use this plug-in to fine-tune brightness, to make a clip behave like it was shot on photo paper, or to correct brightness issues that you may have with the original clip.
- one 256 band graphical equalizer: one each for red, green, and blue
- edit the equalizer interactively by simply clicking the mouse
- pre-sets: linear, inverse, n-step (up/down), bell curve (normal, inverted), hyperbolic (4 variants), level, s-curve (normal, inverted)
- load and save any setting to disk as an editable text file
- choose reference color
- reference color displayed in equalizer as reference line
- factory pre-sets
- real-time preview of equalizer results
- full-size preview window
- interactively define area of effect using the mouse
- effect fade-in and fade-out
- choose color using either color picker or simply select by pointing into clip
