I have a Fuji S2 digital camera which delivers photos up to 6.1 megapixels.
On two different occasions, my clients have told me that my photos were low res and prints would be blurry — according to their printing store.
The files were delivered on a CD in jpeg format at 72 dpi. Is it up to me to set it to 300 dpi or should the printer know how to do this ? Usually I don’t change the format to 300 dpi because it increases the size of the file and all of the photos don’t fit on one CD. Also, the client want the pictures for the web, too, and so the files I send are somewhat in the middle.
Am I doing something wrong ?
My typical jpeg file — as downloaded straight from the camera — is 4.5 MB at 72 dpi. ( The pixels are 4256 x 2848) When I change the image size to 300 dpi in Photoshop Elements, the resulting file is 46 megbytes at 300 dpi and the pixels change to 17733 x 11867.
So what happens when I go to Photoshop and change the resolution to 300 dpi ? Am I not creating a file suitable for printing at 300 dpi ? If I can get a sharp, clear, detailed 11 x14 print from that big fat file, have I not in effect made a high res image– or the equivalent ?
In some ways, isn’t resolution just a setting? However, the quality of the result depends on the information in the original file.
A file that is 100K can also be also printed at 300 dpi — but you will get a lousy 11 x14. In general, a "larger" file may result in a better 11 x14.
Also — as an aside — WHY do my files get larger when I change to 300 dpi ? Where do the extra pixels come from?
Thanks!
