Digital File Sizes and Prints
Hi, Spitfire,
If you're wanting to print 8X10's from a digital camera, and you have a "photo quality" inkjet printer but aren't sure what camera settings, i.e., file sizes, will produce the best prints, here are some guidelines. The file sizes are given as pixel counts; the print size should be considered the maximum not the minimum size that will look good.
640 X 480 (or smaller) = wallet size (This is also the recommended file size for uploading/online viewing)
768 X 512 = 4 X 5 prints
1152 X 768 = 5 X 7 prints
1536 X 1024 = 8 X 10
2650 X 1920 = 11 X 14 up to 16 X 20
Obviously, the final quality of the print will be determined by a number of factors. For example, if your digital has a glass lens rather than a plastic lens (many of the early digitals shipped with fixed-focus plastic lenses), the resolution will/should be better. Also, if your printer can print at, say, 1750 or 2400 dpi, rather than 1440 dpi, the overall print quality will be better.
So, if you're using a digital camera to take pictures of your newest model or of your layout, and you want to make good prints, follow these general guidelines:
1. If your camera has adjustable file size/image quality settings, set it for the largest file size and highest level quality.
2. Set your printer's software to print at the highest quality setting, e.g., 1440 dpi. (And if your printer will accept an optional "photo" ink cartridge - they usually replace the black tank - get one and use it. Most Lexmark printers, for example, will print in 6 colors with a photo cart.)
3. Use a high quality photo inkjet paper, such as that make by Kodak or Ilford.
Now that the big name camera manufacturers - Canon, Nikon, Olympus, Minolta, etc - have gotten on the digital bandwagon, the quality of digitals has improved dramatically. Most come packed with a whole slew of features.
I use a Minolta DiMage 7, and I really like it. It's been on the market for about 10 months now, so I imagine the price has really dropped from what it was originally selling for. It's capable of 5.24 mp.
Hope all of this helps. Good luck with your decision.
