16x20 Prints from a Cannon D60?


It was noted that Cannon D60 is a 6.3 Megapixel, is this enough to make a 16x20 print?

  Certainly. I have colleagues who use D30's and make 16x20's from those files. There are ways of interpolating images in Photoshop to increase enlargement quality as well.

  Try it with one of your highest resolution images files. Open it in Photoshop, Image/Image Size, uncheck Resample, check Constrain Proportions, and enter the longer dimension (length if a horizontal, height if vertical). You will see the resulting resolution appear in the resolution block. Print it and see if you're happy with the results. Keeping in mind that the normal viewing distance with a 16 x 20 is pretty far, it may be OK, even if the resolution you feed into the printer is less than the generally accepted minimum 240 ppi. If you want/need better quality (ink dots less apparent), try checking Resample and increase the resolution AND the dimensions to 240. Better do it in small steps. Pros use a program especially for this called Genuine Fractals. If you do a lot of this, try GF.

  Actually, there's a better way than Genuine Fractals to enlarge images in Photoshop. You go into image size and enter the size you want to go to and make a note of the resulting file size. Don't click ok yet. Now, go back to the original size. Then under document size switch from inches to percent and enter 110%. Now click ok. Continue to do this until you get close to your target file size. Once there you can nudge it to the exact size you wanted. I've seen comparisons between this method and GF and this is just as good if not better. Best of all it costs you nothing!

  Thanks, Jeff. By helping Al, you've taught me something, too.
