Cassandra: Photos on the Mac (4) - Filtering with Black & White
By Graham K. Rogers
Image with Color Adjustments Applied
With an image that is predominantly red, applying the Red filter will make that appear a light grey. Likewise, with a green or blue filter the red section of the image will appear far darker. Care must be taken when applying these filters to faces as the effect may be far too strong for some complexions.
