leica iiif shutter test 25th sec

This is one of a sequence that I took with this roll to check that the shutter speeds were working correctly, and to get more information into my head so that I begin to do the iso/shutter/f-stop/available-light algorithm in my head; (hereinafter, "The Algorithm").


leica iiif shutter test 25th sec, originally uploaded by Pig Sty Avenue.

This one's a 25th of a second, and there's no camera shake, (I think there's a tiny bit of fuzziness at speeds 15th, 10th and half, and a lot at B, about 2 seconds). It means I can get away with 1/25 (and two deep breaths) which would surely be more than enough in even dim light at 1600, f2 or even f2.8.

This was at 400 iso, f2.8, full spectrum light.

Leech or flatworm? Ants and Swiss Chard

Image
For the 2nd time in a week or so, (1st time regarding dwarf beans ), I'm following Alys Fowler's advice, this time with regard to Swiss chard .  Long story short, after midsummer plants which often bolt if planted in spring will resist the impulse to do so, probably because of shortening days; (I say shortening, but in Glasgow, in July, we're still getting 18 hours of daylight).   I got a packet of Bright Lights , at a good price, (another reason to wait until July before sowing, lots of bargains, I've noticed). But where to sow them? Most of the 2nd bed is under a tarpaulin, but it wasn't quite big enough to cover the whole bed, so the last 5ft or so went under a sheet of plastic, (in the background of the photo in this post, here .) Transparent plastic was a foolish idea, weeds were growing underneath it, so I covered most of it with sheets of metal from the old shed. I decided to leave the tarp, but use the area beneath the plastic for the chard. Who-ah there...

"Chevy Chase. Fuck ever happen to him?"

As Paulie Walnuts said in The Sopranos. It got me thinking. As it happens, he's been working steadily , but you can see what Paulie means. It's like that with film and television actors: you don't see them in anything for a year or two, and you wonder if they're dead or perhaps on a lengthy charlie and booze session. Or maybe doing proper acting on the stage? Only appearing on the telly gives them meaning to us. That video with Paul Simon was on one of the cable music channels the other day. It always makes me smile. As for Paulie and the rest of the crew, the clock's ticking. Of course, America already knows how things finish, but we don't. My mate Ian was telling me about a friend of his, visiting the States a few weeks ago, flicking through the channels in his hotel bedroom, he hit on a repeat of THE final episode, just beginning. What a quandry! He watched it, as it goes, but kept shtum when he came home.

Sex Sells Cars

That's my mate Stewy, who nowadays mends really expensive hospital equipment when it goes on the blink. But years ago, he had a modelling contract with Lada cars. I think it all ended badly, for him and for Lada.
