Size Of Photographs

You can find lots of discussions regarding this issue. Resolution is mostly irrelevant, the size in pixels determines the maximum printable size. As a rule of thumb you must have at least 100px for an inch. So if the minimum print size is , let's say, 8" on a side, you must have at least 800px on the image.

The largest size your camera produces.

I think there's a 25 megabyte file size limit, but otherwise you should have as many pixels as you can produce. More is better than less.

Barbara,

Welcome! Really, it's simple, whatever the camera produces is what should be uploaded, AS LONG AS IT'S UNDER 25MBs. If your camera shoots RAW, then the dpi will be 300 and whatever the size of the image, mine is a full-frame sensor and produces a file with the dimensions of 3744 pixels x 5616 pixels and that's what I upload, after editing it in Photoshop. If your camera ONLY produces a jpeg then the dpi will be 72 and that's fine too, don't change anything!

Also, the dimensions of the widest side, mine is the 5616 will then produce a print up to and sometimes larger than a 56" print!

Hope this helps....

There appears to be a tiny bit of flexibility on the 25MB upload limit. I never check my file size before upload and very occasionally, a 26 or even 27 MB file has successfully uploaded.

Philip,

Same here, but I wouldn't count on that happening every time!

Rich

Rich, my files are normally well below 25MB, so upload rarely a problem, think the only time I got stopped by the FAA border force was when a 28MB file tried to sneak through.

It is not flexibility, but compression.

Philip,

My old Canon 1Ds MKIII captures 21 MPs and sometimes after playing around in Photoshop, will still end up with a file larger than 25. Sometimes they get through and maybe 27+ or so and other times, 25.5 gets kicked back! No rhyme nor reason.....
