| Digital print size?
Hello all,
I took some sharp pictures of my wife using the L of D90 4288x2848. I spent some time Googling and found that with 4288x2848 one would need to get 36x24 prints? Is this correct?
I got the calculation from:
4288/300 (300dpi)=14.29cm x 2.54= 36"
2848/300 (300dpi)=9.49cm x 2.54= 24"
It's quiet pricey to get prints like that! Would it be sufficient if i can crop it to 11x14? The smallest resolution i can do with the D90 is 2144x1424 which would mean a 18x12 can i use that to make 11x14 as well?
I guess any online digital print place would do that for me e.g. adormapix.com which is still having the $1.99 for 11x14 sale!
TIA!

| the printing setup of any printer will scale the image file down to whatever print size you like.
try 8x10 glossy paper in your own printer,
with the printer settings put to maximum quality and set to glossy paper. (close enough for most folks, but inkjet ink smears with water.)
you are right about the mailorder places for bigger prints, they scale it down for you.
alternatively, many walmart/cvs etc places have photo kiosks, into which you can cable the camera or insert the mem card. then right away in a few minutes you can get photo-paper 4"x6" prints for $0.29 or 8" x 10" for ~$6. |

I'm not sure where you got 300dpi, but the resolution is determined by the printer. Even so, images that don't contain text can be scaled down pretty easily.

I'm don't understand your math.
4288/300 (300dpi)=14.29 in. cm x 2.54= 36"
2848/300 (300dpi)=9.49 in. cm x 2.54= 24"
To print 36" X 24" at 300dpi you need 10,800 X 7,200.
With that said, 300 DPI is generally considered what you need to get prints that are visibly indistinguishable from prints made from film.
That number is way over rated, just a rule of thumb, and doesn't take anything else into consideration.
Don't let that stop you from getting a print made with a lower resolution. (Price is something else though)
As for printing to a different size paper, you can print to any print size you want.
You will just have to crop or trim off something from the length or width to make it fit. |

Simple solution...

JPEGCrops will crop your image down to the desired printing size and takes care of everything for you. Then just print or send off to printers.

A professor told me that the image dpi should be a fraction of the resolution that you set the printer to. So for example, if you set the printer to 1440dpi, then you can set your image at 360, 288, and 240 among other resolutions.

What did he say the reason was? |

This was not the teacher to question. He collected PSDs from students so that he could make sure that they contained the right adjustment layers. I got the label of "troublemaker" for bringing up too many questions.

If you use multiples of the dpi, or whole factors, then the printer doesn't need to go through the "resample" algorithm, which tends to blur the image. |

The label came from a staff member, and the teacher said that I had reputation that followed me around. The "troublemaker" thing was more of a joke. And by questioning things, I mean not doing things the way the teacher tells us. I'd do stuff like adding a color balance adjustment layer when the teacher told us to make adjustments with a curves adjustment layer. Wow, I have strayed far off topic.
Also, remember that these sizes are for the actual images, not the paper. Consider what type of border you want, if any.
