Dpi

[ILUV2SO2]

I submitted photos for processing to Costco. They just called and said 5 pictures could not be printed because the DPi was too high. (They only print at 5000 - 7000 dpi) I'm not sure how to change the dpi? Anyone know how for a Nikon D 90?

Haha, this is NOT what I expected to read in this thread! (There are way too many threads here complaining about LOW dpi).

"DPI" in this context refers to the number of dots printed per inch of paper. It's basically how many pixels from your image have to be squeezed into each inch of printed paper. I believe that the D90 is 10 megapixels (or maybe it's 12...) -- at any rate, more than enough.

Did you ask Costco to print the images at a very small size? (For example, wallet sized?) If so, they might be trying to "squeeze" too many pixels into an inch -- in which case, you can just scale the image to something smaller (maybe 50%) and try again. However, it seems VERY odd that they can't just do that for you...

Setting dpi in software, or in your camera, however, is pointless. Until you actually print the image, it's a meaningless number. Costco and other similar printing services will just take your image, ignore the DPI setting, and try to squeeze it into whatever sized print you asked for.

Nobody prints at 5000-7000 DPI: call them again and ask to talk to someone who knows what they're talking about.

Yeah, even a 12 megapixel image printed at 2x3 inches would only be 2000 dpi. Something's fuuuunky!

Im not even sure 5000dpi is POSSIBLE.

The only thing I can find is their minimum is 120PPI(DPI).

I've never heard of being unable to print an image with too much PPI/DPI....

Maybe there was an extra 0 in that original post?

The other option would be to just size the photos correctly in Photoshop

Even so, I've never heard of 500DPI either. That's beyond what the eye can distinguish, so there's no bloody point.

I've heard of 600DPI for high res "magnify it with a loupe" images, but I agree.
