Picture Quality / Size Options (8.25)
The GX-1S's four image resolutions are 6 megapixels, 4 megapixels and 1.5 megapixels. 4 is good for snapshots, and 1.5 is good for computer screens – emails, the web and PowerPoint, for example. The GX-1S shoots RAW format at full resolution and also offers three JPEG compression levels: Super Fine, Fine, and Normal. Fine files are about half the size of Super Fine files, and Normal is 1/3 to 1/4 the size of Super Fine. We recommend sticking with Super Fine for all uses, as the higher compression levels really damage image quality.
