Adjusting Gamma

The colours that you see on the screen do not necessarily match those that will appear on paper or even when you view the same image on a different screen. Paint Shop Pro provides an option to allow you to set the screen colours correctly so that an image will display correctly based on the colours that have been selected.

The option to do this is called Monitor Gamma Adjustment and it can be found in the File menu under Preferences.

So how do you use it? Well on the left of the screen you will see a number of coloured boxes - red, green, blue, and grey. The outside of each of these boxes displays a dithered colour combination of light and dark dots while the centre of each colour block is set half way in between. If the gamma on your monitor is set correctly the entire block will appear the same colour.

The idea is to slide the controls to the right of each of the red, green, and blue boxes until the outer and inner blocks blend into the same colour. With the linked channes checkbox selected the three sliders will slide together. Once you have one or two colours right you then unselect this and adjust the slider(s) for the remaining colour(s) until the colours blend (or come as close as you can get it).

Once you have done this selct the OK button to save your changes. The gamma settings in Paint Shop Pro are now correct to display colours on your screen properly based on the allocated brightness of the colours. Any images you display will appear exactly the same as they would on any other monitor where the above steps have been followed.
