The default gamma settings for Macintosh (1.8 target gamma) and Windows (2.2 target gamma) monitors are quite different, and this can lead to unpleasant surprises when you first see your images displayed on “the other” platform. Mac users will see darker and more contrasting images on Windows displays; Windows users will see images that seem more flat and washed-out when seen on Mac displays. Most web designers opt for a middle-ground solution, lightening images slightly if they work on the Macintosh; darkening images slightly and adding a little contrast if they work in Windows. Web images processed with Adobe Photoshop’s “Save for Web” option will automatically adjust the gamma to an intermediate level appropriate for both Mac and Windows monitors.

So para dun pala yung Save for Web? Ngayon ko lang nalaman, okay. Galing.
