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.

LTPTP XXV: We Shall Overcome

Image
We shall indeed.  It's a lovely wee tune to learn.  I've almost memorized it this morning, the idea being, when I encounter a piano, I want something to sit down and play on the bugger.  I've a feeling that my keyboard's keys are lighter than a proper piano's, and there'll be a bit of effort transferring the skills I've gotten so far.  Probably, at some point this year, I'll be in workplace with a piano.  I'll print off some simple music and scales, and work at it, but it's likely to be in a public place so I want something to avoid making a twat of myself initially. It feels right that this should be the first tune I learn by heart.

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

VINEGAR!

That wine I started a while back has turned to vinegar. Well, that answered questions I was asking myself back then, viz., 'Do we get vinegar flies around here?' And, 'Are all these little flies vinegar flies?' The fuckers. I thought I was being a clever recycler, not buying proper air-locks and using the old plastic-and-lacky-band method. Ah well, another step up another learning curve. Anybody need three gallons of white wine vinegar and two gallons of the impossibly exotic strawberry wine vinegar? It's been a 'business day', dealing with officials and filling out forms. Don't get me started! Alex came over tonight. He gave me the Aphonic CD (he's been in touch with them and they sent him several copies). I thoroughly approve of this new trend of bands getting their work known over the internet, by-passing (initially at least) the poisonous attentions of the music industry. Come to think of it, some of the people in that business are rat
