The Brightness operation alters the brightness value for each pixel in the selected area. F/x calculates brightness based on a linear measure of how far from a brightness value of zero each pixel is. The larger the value the brighter the value. Brightness values can range from -100 (minimum brightness) to 100 (maximum brightness).
§ 16.102.1 - Contrast Controls
§ 16.102.1.1 - Trends
Operator dialog controls that have a Trend button next to them offer animation functionality. Trend allows you to set that variable over a set of frames. Each frame of the animation can be thought of as a slice of time. The trends allow you to alter some, all, or none of the variables for a particular time slice. Variables that have multiple states can be set to any of a number of values in the trend. Variables that are either on or off can only have an on or off value in the trend. You will notice that the trend graphs have equidistantly spaced vertical lines. Each of these lines represents a frame in the animation. The number of frames can be altered using Sequence controls... in the TimeLine pull down menu. Animation lengths of 100 - 999 frames will be represented with a vertical bar being 10 frames, and animation length greater than 1000 frames will have a vertical bar for every 100 frames. Click here to view more information on Trends.
§ 16.102.1.2 - Brightness
The brightness settings can be altered by using the slide gadget, or by clicking on the text entry field and entering the appropriate value. The brightness operation defaults to 100 which is the maximum brightness change. The brightness can range from -100 to 100. Setting the brightness to 0 will cause no change to the image.
