I'm curious if photographers that upload to various photo service sites such as www.pictage.com (no longer in business apparently) or www.gradimages.com can unwittingly have their content resized/resampled. I'm trying to make sense of how these images I bought are found with such a low dpi/small size. It's hard to imagine a pro would go cheap on the resolution. I know one was an aspiring amateur but the other I would assume was a professional taking grad school photos.
To share some data
WeddingPhoto1.jpg Width 3744 pixels Height 5616 pixels Horizontal resolution 72 dpi Vertical resolution 72 dpi Camera model Canon EOS 5D Mark II GraduationPhoto1.jpg Width 1488 pixels Height 2240 pixels Horizontal resolution 300 dpi Vertical resolution 300 dpi Camera model NIKON D70s
The first is a poor DPI resolution, the second is on the small side. I'm wondering is there a table or some way of knowing that the details found in an image's metadata correspond to anything the used camera is capable of natively generating?
I would also welcome any commentary or insights into the particular values seen for these photos, whether they'd be up to the task of printing say an 8x11 or poster size, etc.
