“Grab”

I so much as turn that web-cam on, and the garbage-train. (Grab screenshot by the mighty MAC.)

Pictured above is a screenshot of what the web-cam sees at the mighty Curve.
There is a video camera at Horseshoe Curve that feeds its images onto the Internet so I can see what’s happening at the Curve on my computer monitor.
The web-cam is on all the time, so it’s always projecting an image; e.g. pitch-black at night (except for the headlights of passing trains).
It’s old and in a dreadful clear-plastic housing, so mottled and filthy the camera often auto-focuses on the housing instead of the tracks.
I watch it so much I offered to replace the housing — no bites.
My ‘pyooter, an Apple Macintosh, has basic screenshot functions integrated into the operating-system. Apple-shift-3 screenshots the entire screen. Apple-shift-4 screenshots only the part of the screen I select; e.g. the web-cam image.
Both screenshot commands save the screenshot on my desktop as a .png, which I convert to .jpeg.
I also have another screenshot doohickey: a software application called “Grab” that came with OS-X.
The web-cam screenshot above was done with that.
First I have to fire up Grab, and then mouse the area I want to screenshot.
This action is a menu-command (as opposed to keyboard). Grab has others.
Apparently Grab doesn’t save the image-file anywhere — it’s a software display.
All it does is display your screenshot on the screen.
So here I am stabbing all over trying to find the file, when it hasn’t even been saved yet.
My search, of course, went nowhere; until I saved the screenshot.
It’s the old waazoo; I have to know what’s going on.
I could then open the file in Photoshop-Elements, and dicker for as above.

RE: “mighty MAC........” —All my siblings use PCs, but I use an Apple MacIntosh, so am therefore reprehensible and stupid.

Horseshoe Curve (the “mighty Curve”), west of Altoona, Pennsylvania, is by far the BEST railfan spot I have ever been to. Horseshoe Curve is a national historic site. It was a trick used by the Pennsylvania Railroad to get over the Allegheny mountains without steep grades. Horseshoe Curve was opened in 1854, and is still in use. (I am a railfan, and have been since I was a child.)

RE: “The garbage-train......” —The railroad, Norfolk Southern, operates a train of containers filled with trash. These containers, which are blue, are loaded on trailer flatcars, and the train runs daily. You can see it every day between 10 a.m. and 10:30. The “Garbage-Train” screenshot was at 10:25 a.m.

The dreaded “Apple” key, also known as the “splat” or “pretzel” key, is more-or-less the equivalent of the Windoze “control” key.

“OS-X” is the Apple operating-system I use.
