==Irfanview: Adjusting parameters (color, brightness etc.)==
 This has the purpose of "realistic" appearance (by default)
Some images can be color reduced (the color depth), even with a result in increasing "subjective" quality.<br>
Others do not take color reduction well, or the filesize increases above that of JPEG.<br>Try to modify parameters in this sequence: First the Saturation, then Contrast, then Gamma factor, then R/G/B intensity. Adjusting Brightness easily gives unrealistic results.<br>It is possible to operate these factors artistically, but most likely a "normal" image should be archieved. This means how it would like to appear in daylight at 12pm, or under standard office light. Too bright images can disappear completely on some monitors. Generally different monitors can cause a change of 50 percent, there is never "exact" reproduction. In case of doubt, test the image file on different computers.

'''Select the Image menu.''' Then select "Enhace colors".
