I have done a search for this subject since I know that it has come up before, but still didn’t quite get what I am looking for.

I have an array of dig images that in their native state range between 3-17MB,they were shot as JPG Large, and now would like to print them as large as I can for resale. I am planning to have a prof. lab do the printing.

I am able to print some large files 115MB using my Epson 1280, but it contains multiple 3×3 images, so far the quality has been outstanding. But now I am facing a little dilema, I would like to print some single images as larger than 16×20.

So how do I figure it out figure to determine the maximum print size?

The file size is irrelevant. You need to know the resolution (at least 200 for photo quality, 300 is better) and the pixel width and height of the images. So you will need 200*16=3200 (or 4800) by 200*20=4000 (or 6000) as the pixel dimensions of your images.

There are other considerations. What he said was right….but there is more. Generally, comfortable viewing distance is twice the diagonal. So a poster would not have to be as sharp as a photo album print. Generally you can take most digital photos to 8×10. If you can be happy with a 2 mp camera…then an 8×10 from that camera won’t disappoint you. If, on the other hand you know better and have a 4-6mp….you will be happy with an 8×10 too.

Going larger? I wanted to put my 4mp camera to the test. I shot a photo of a woman in a lace teddy…lots of flesh and lace…quite a challenge. I ran it through Genuine fractals and had it printed poster (about 3.4 feet) size on paper and canvas by a professional printer. GF seeks out the high contrast areas and preserves them during the blow-up. Then it replaces them as lines as sharp as the original. On paper the print was stunning. The flesh tones were smooth…the lace was detailed. On canvas the print was a work of art! The texture of the canvas helped hide the fact that there was less detail than might be expected. At proper viewing distance it was terrific…and up close most would find no fault with it.

Now, if we could only get judges to quit looking at images with a loupe..

If you are asking what I think you are asking, the last post was correct… However, I usually mess around with the image dimensions such as 8×10 and so on. Go under "Image" in the drop down menus and go under "Image Size". Like Don mentioned, stay around 200-300 resolution for good picture quality. But then put in the coordinates that you want as far as size goes. Make sure to click on "constrain porportions" at the bottom to make sure your picture doesn’t get twisted. I hope this helps and this is what you were looking for. I resize all my images this way and normally stay at 300 resolution.
