This is a simple effect; it adjusts the contrast of the entire image.
For this effect, values in the range of 0-49 decrease image contrast; values above 50 increase image contrast; value 50 for the setting does not affect the image.
Setting the contrast slider to 80 adds sharp contrast to the original image in this time lapse software effect setting.
Note: You can add a precise value for the slider. Just double-click on the percentage number to open up the percentage editor.
Note: this effect is available in the free version of Time-Lapse Tool.
