oh - the hp photosmart 850 stores the pictures on a secure digital (sd) card or on mmc cards. the still shots are stored in jpeg with 2 resolution settings: 4MP - 2272x1712 or 1MP - 1136x848. and then each has 3 compression settings (good, better, best). the shot above was with 4MP and "better". video clips are stored in mpeg format. and i will replace the included 16 mb card soon with a 128 mb card. for more information have a look here: https://www.steves-digicams.com/2002_reviews/hp850.html

thanks
