We wanted to be creative, didn't we? KView provides some filter functions to manipulate images. They are (conveniently) placed in the menu. Firstly, we will change the so-called “gamma factor”. This value affects mostly the mid-tones in the picture, leaving the brightest and darkest parts more or less untouched. Choose ->-> from the menu bar. A dialog box appears. Change the value to 0.4 and hit the button. The picture is somewhat darker now:
After the gamma correction
For a little psychedelic touch we use the brightness function. Selecting
Brightness again brings up a dialog. This time you can enter the new brightness
expressed in percent relative to the original value (so 100 percent means
“initial value”). Enter a value of 300.0
300>
and watch what happens:
KDE brighter than ever before
Finally, we blur the image a little with ->. Apply this filter two or three times (or more often if you can't stop!). The smoothing filter reduces the contrast between neighboring pixels:
KDE - smooth as silk
