Conclusion: Overall, the HP Photosmart 635 is a great beginner's camera but lacks some functions that cameras of this class have. Image quality issues (Especially macro mode), no continuous shooting, slow playback and tremendous shutter lag leave a lot to be desired. The good things about the HP Photosmart 635 is the unlimited movie mode where exposure is automatically adjusted and excellent infinity focusing.
Pros: Unlimited QVGA movie mode with auto exposure, Excellent infinity focusing
Cons: No built-in lens barrier, Slow (Both playback and shooting), Macro almost unusable (Constantly out of focus), Movie mode resolution only at QVGA, noisy movies, Redeye, soft macro photos and color fringing, Inaccurate battery indicator
Summary: The compact HP Photosmart 635 digital camera with HP Instant Share produces crisp photos with 2-megapixel total resolution and 12x total zoom (3x optical zoom lens and 4x digital zoom) for outstanding close-ups. The pocket-sized camera comes with 16-MB internal memory and an SD memory card slot for the option to add more memory. Choose between automatic or manual controls to select camera settings for ISO, exposure and white balance.
