Which image resolution?  72 dpi /ppi, or 300 ppi / dpi?

I feel that as modern photographers who shoot with digital cameras, there are a few basics which we absolutely need to know and understand. Some concepts that are so intrinsic to the digital format, that we have no excuse not to grasp them. One of these things would be the resolution of images - the image size. Not in kilobytes or megabytes (since this is rooted in a more archaic form where images were scanned) - but image resolution as in pixel dimensions. Megapixel size. That kind of thing. The confudled question often then  Read more inside...

Image size & Resolution - 72dpi or 300dpi

I live 20 miles at 65mph outside New York. Yes, that sentence is pure nonsense. I live 20 miles outside of New York. That's it. The complete description of the distance. Now that 20 miles of course could mean either 30 minutes or 3 hours of driving, depending on traffic through the Lincoln tunnel. But I digress. I could have described my distance from my house to New York as 20 miles, or disregarding traffic, as 18 minutes at 65mph. But it is nonsensical to describe my distance from New York as 20 miles at 65 mph. The 65mph becomes a  Read more inside...
