The title is pure nonsense. I live 20 miles outside of New York. That’s it. The complete description of the distance. Actually, I live 21.19 miles from B&H in Manhattan, which is like magnetic north for many of us photographers. We always feel drawn towards the toy-store. Now that 21.19 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 superfluous bit of data when stated like that.
So why the strange title for this posting? Because as a digital photographer I see the same kind of nonsense perpetrated on a daily basis when image size is described in terms of absolute pixel dimensions (600 x 400 pixels) and a specific dpi such as 72dpi or 300 dpi also demanded.
It is unnecessary, or worse, confusing.
