    this is called upsize. lots of pixels will be lost.
    better to take on 1024, or 1280 then downsize.

    no. 4R = 4 inches by 6 inches. a digital image has no "print size". you can print any image at any size just that the quality may suffer.

    i'm no expert but a 4R is 4' by 6' and at 300dpi (for inkjets) you would need a 1200X1800 size file (2.1MP cam?)....but I've seen Fuji Frontier machines do it at around 200dpi --- so it would only require a 800X600 file for a 4R print...so your 1.2MP cam would suffice...any larger and you proably would get degradation....

    erm... for a 200DPI 4R size print, the pic should be 1200x800....

    hehe! u are rite! hehe!
    anyway, a 1200X800 still yields a file less than 1MB,so the 1.2MP cam can still print decent 4Rs..rite!?

    I believe most shops will indicate what is the recommended size of photos to submit to them for various print out size.

    4 x 6 inch = 400 x 600 if image at 100ppi
    = 800 x 1200 if at 200 ppi
    = 1200 x 1800 if at 300 ppi
    so i think u get the idea

    whatever, just send in pics at the highest resolution that your camera can produce. there's no need to degrade quality unless you need to send in files on a diskette. There's no need to worry about what "DPI" the printer uses too.
