JPEG uses a “lossy” compression algorithm. That’s basically the secret of why a JPEG version of an image can be so much smaller than a PNG or TIFF; it’s because the JPEG throws away some of the information. Continue reading Resaving JPEGs
Digital Cameras and “Focal Length”
This is a very simple subject — complicated by people like me arguing about proper use of terminology, and people trying to explain differences that other people haven’t even noticed, and people pontificating on things they don’t adequately understand.

Rifles and Me
With a tiny number of exceptions (and no decent training, and in hindsight the people I shot with before were not competent), I didn’t start shooting until about 1978. Then I started with handguns, and the people who started me then were competent and gave me an excellent introduction to safety and shooting skills. (I probably wasn’t competent to have that opinion until last year; but now that I’m an NRA certified instructor in several areas including pistol, I think I have a decent idea of what a good introduction looks like.) Before this last year, I don’t think I’d fired more than 5 rounds from rifles — some .22, and I think one round from a .223.
Timing Is Everything
Went over to the TCF in Uptown this afternoon to make a deposit, as I do most weeks (sadly, the deposits are mostly small). I would have gotten there around 2:15pm I think. I’m in the habit of going to a teller window, and usually get some cash back.
On the way in past the ATM, I noticed a lot of people sitting around in the lobby. Then the door failed to open.
Finally, I noticed the sign on the inside of the glass door saying “Temporarily closed due to robbery”.
