The standard CNTL control sliders present an active preview on the image. Once the adjustment is statisfactory clicking once on the pictue will 'lock down' the changes and return the sliders to center position. A histogram display below the slider controls indicates the distribution of pixel values in the current image. ChromaPIX provides one level of undo operation for most functions. Undo is available under the edit menu.
Undone operations can usually be Redone from the same menu.
This gives you an easy way to compare two 'before' and 'after' images. If you have the screen area it is usally very handy to run with more than one front panel. The use of more than 2 panels is not recommended under Windows 95.
