If the total is less than 100% then the picture will be darker than the original if it is greater it will be brighter. The “absolute” choice allows the total to vary. This keeps the overall brightness of the image constant. When you choose relative, the program recalculates the percentages for the channels so the total is always 100%. And the ones labeled “ROYGCBPM” let you adjust specific colors as well.īoth RGB and ROYGCBPM have a relative and absolute option. Each allows you to input specific values for the red, green and blue channels. The other four presets, Absolute RGB, Relative RGB, Absolute ROYGCBPM, Relative ROYGCBPM, are more complex. Channel Mixing and Special Effects using the RGB and ROYGCBPM preset options That will move you into more sophisticated tools with the preset you chose already set. If, after you try one of these, you feel like you are close but want to fine tune, choose one of these four presets: Absolute RGB, Relative RGB, Absolute ROYGCBPM, Relative ROYGCBPM. These presets are simple to use: select a preset then experiment to see if you like one of the color filters. Of them, 11 are preset percentage values for the channel mixer. The post Black and white digital processing part one talks about the different effects you can achieve by changing the mix of channels, and it includes a table of the percentages that can be used to emulate types of black and white film. In this mode you can apply a color filter to the entire image then customize the channel mix.This acts as a physical filter on your camera at the time of capture would. See below for a more detailed look at these options. Select a film simulation Lut from the drop down list.Įnjoy the applied film simulation !
