Agree with dixeyk. I bought it because I could not afford Silver Efex Pro, which seems to be preferred by most people, but I hate having to open each file, one by one, in LR, then having the B&W effects close as soon as I hit OK, having to do the whole thing again for the next black and white image. But it does do a good job once the clunky interface is got through.
I do indeed remember the Iron Lungs. I don't know what I feared most when I was a kid growing up in the early fifties, the iron lung or the polio injections at Dr. Fitzgerald's office. (Needles weren't as "micro" as they have since become.)
