F717 dpi

[toobigtocr]

hi,
i am a newbie to this site so here goes.

i bought a F717 on ebay about 8 months ago and i absolutely love it, but there is one thing i don't like that i have only just realised. when i put the images onto the computer it says they are only 72 dpi (good for screen resolution) but i am wanting to print some of them. therefore i need a dpi of 300 (250 minimum) anyone got any ideas of why this is happening? or if this has happened to anyone else. i would have thought in a 5megapixel camera that it would shoot in 300 dpi. i have looked through the camera's manual but says nothing about it.

any feedback would be appreciated!

cheers

This is quite normal and happens with all photos taken with a digital camera because their size is expressed in pixels, not inches. A PC monitor has a fixed pixel dimension of 72 ppi (pixels per inch), so if the digital image you import has a size of, say, 2000 pixels x 1000 pixels, that image will be shown on the display monitor at 72ppi in width and length. That works out at 27.7 inches (2000/72) x 13.8 inches (1000/72). Obviously you don't want to print it out at that enormous size (and in any case 72ppi is too low for quality printing), so you use a photo-editing application to increase the pixels-per-inch to something like 300 which will automatically reduce the image dimensions accordingly to give you a new image size of 6.6 inches (2000/300) x 3.3 inches (1000/300). The sizes I've used are for example only, The actual figures will depend on how many pixels are in the original image from your camera, but the arithmetic is just the same.
