Introduced in mid September 2008, the df300a1 is a miniature 3.5" digital photo frame from HP. Coupled with a leather traveling case, the frame is aimed at people who want to take their photos on the go. With a 4:3 resolution of 320 by 240 and a contrast ratio of 400:1 the frame contains both a rechargeable battery that is rated for 2 hours and internal memory that can store up to 45 JPEG images. The frame also takes SD, SDHC and MMC cards for further expansion of the internal memory, and can be charged via AC adapter or USB cable.
