If you're just posting the images on a web page then a lot of digital cameras will do just fine but for good, photographic quality prints, you need pixels and lots of them. So if you have the option to set your camera to a higher resolution, do so if you think you might want some photographic quality prints made later. Resolution is the total number of pixels in the image file. High-end digital photographic quality printers need 300-400 dpi (pixels per inch) so if you're wanting a good 8x10 made then you need to have 3000 to 4000 pixels in the 10 inch dimension. Few digital cameras have this kind of resolution. Yes you can enlarge it in Photoshop and it does a reasonable job interpolating pixels but there's no substitute for capturing the image with the number of pixels you need.
Now if you're just printing them out on a desktop inkjet printer with photo paper, you can probably get by with far fewer pixels. Probably somewhere in the neighborhood of 150-200 dpi. JPEG compression is also something to be aware of and it's not directly related to resolution. You can have a very high resolution file (lots of pixels) and then ruin it by compressing the snot out of it. JPEGs compress an image by throwing away data from the image file which then has to be reconstructed when the file is opened and printed. The more compression, the less quality. The more quality, the less compression. Check your digital camera files. When setting some digital cameras to a higher resolution, they don't capture with more pixels but instead only adjust how much compression the image gets. Keep in mind that if you have more pixels and less compression, your image file is going to be larger and you will fill up that compact flash much faster forcing you to download them to your computer. ------------------------------------------------ Tom Roth * [EMAIL PROTECTED] * tel 336.716.4493 Wake Forest University School of Medicine Dept of Biomedical Communications Medical Center Blvd * Winston-Salem, NC 27157-1011 http://www.wfubmc.edu/biomed/ -- PowerBooks is sponsored by <http://lowendmac.com/> and...
