How to lose friends and alienate Flickrites
How to lose friends and alienate Flickrites
Oh dear. It's all very difficult. I always feel slightly embarrassed when I take photographs in public. The trouble is that I find photographers rather a tiresome tribe and don't like to be mistaken for one of them. Some contradiction here, you might be thinking ...and it's true that, in my time, I might have taken quite a few photos. But, you see, what I do is perfectly OK. To create pictures is a natural human impulse and photography gives people who have no aptitude for drawing or painting ...which is to say most of us... a chance to play around at it. It is the more earnest type of snapper I find so insufferable. It is his contention that Photography Is An Art. Of course it is nothing of the sort. Oh, don't get me wrong; a well composed, exposed and printed photograph is a thing of beauty. I love to see such photographs and aspire to take them, but even in the hands of its most accomplished practitioners, photography is no more than a modest craft. Our "photography is an art" man, aware, deep in the centre of in his bones, that he is no more than the operator of an instant, push-button mechanical contrivance, a sophisticated toy, suffers from an inferiority complex, for which he compensates with delusions of creativity That "photography is an art" is the premise of a magazine that Mrs B buys. Oh all right ...it's Black & White Photography (?3.99 monthly). I'll tell you ...if I see another photo of a jetty jutting out into water that's all sort of white, misty and smoothed out, or long exposures of waterfalls, or water swirling around rocks on a beach, well I don't know what! Everything is printed dark, so that the subtle tonal range of black and white is lost. I think this is supposed to look more "gritty" and "real". They are fond of reproducing photographs with a ragged, scuffed-looking edge ...because photographers are really involved in a branch of printmaking, you see. The pics have pseudy titles like (with a copy before me, I choose at random), Homage to HCB (we all know who that is, right?), or The Cobb, Study 2, Lyme Regis, Dorset, England, 1997 (lots of commas, but no full stop). A few issues ago, the "work" of a group of photographers was featured. Most seemed to have "projects" in hand, usually to "document" the lives of the last samphire gatherers in Galway Bay, or somesuch. They were asked to nominate their favourite photographers; all seemed to have unpronouncable oriental or eastern European names. "Landscape photographer Michael Kenna is perfectly at home in his own company. In fact, his meditative approach involves establishing friendships with the trees, lakes and skies that surround him... "...watching a professional photographer at work is always fascinating. Even at a distance you can feel the prickle of excitement just before the shutter is released, a moment of energy that suggests a connection between artist and subject has been made". Ah shaddduuup! And photography is the latest nerdy hobby to be re-invented as an "extreme" activity, for which you have to buy accessories. These days the mags are full of advertisements for "stealth" gear ("you don't carry your equipment, you wear it"), modeled by loutish-looking men in early middle age with shaven scalps. Having had the misfortune to lose most of my hair, I retain my few remaining wisps largely because I wouldn't like it to be thought that I subscribe to this brutish fashion. Similarly I feel rather self-conscious taking a photograph like this because I wouldn't want to be mistaken for a follower of the fashion for "street photography". I just take the odd snap out of doors now and then which, if I happen to be urban surroundings, means in the street. Oh, the photograph. It was taken in Cambridge the other week. The bicycle is very much a Cambridge peculiar, with basket for carrying textbooks, lecture notes and doctoral theses. The camera was my Pentax SP500 with M42 screw-thread Chinon 35mm lens. Exposure was guesswork. Fuji Neopan Acros 100, developed in Rodinal.

bike 180 - ride 17 today i rode for the first time with two new pieces of kit - which is always nice. (i was going to start this post with 'i have been sent...', which is true, but the bloggers and reviewers who usually do this didn't usually have to pay for the goods they are reviewing/advertising). anyway, first up is my new front light. it is a hope vision 1. an AA cell powered, LED light, all the way from barnoldswick in lancashire, via chain reaction cycles in ballyclare in northern ireland. the materials used to build the light are lovely. fantastic, lacquered, blue-anodised aluminium body and aluminium-bronze bushes in the ballistic nylon clamp - all beautifully made. however, the shapes that those lovely materials are made into is not so good - not good at all. the thing is ugly. saved only by the loveliness of the bits. when i ordered it, i also ordered four rechargeable, high-capacity batteries on ebay. they charged overnight and the light was ready for the ride in this morning. it turns on on the 'low' setting and at that, it was already brighter than my cateye el530 and i still had 'medium', 'high' and 'max' to go. you can find beam pattern pictures and run time charts elsewhere. suffice to say that for my commute along pitch dark country road, 'medium' was enough but 'max' is great. for its size the thing is brilliant and thoroughly recommended. it also has a flashing mode - useful for built up areas with street lights and traffic. the flash rate is... ummm... leisurely! it flashes on and off at a far slower rate than any blinky i ever used before and while i like the way everything that is reflective* is lit up by it, i'm sure i rode more slowly. my cadence matching the flash rate. *(and it isn't until you get a high powered light like this that you realise quite how ubiquitous 3M's scotchlight is in built up areas - street signs, registration plates, workmen's coats, car trims &c.) only two negatives for me so far - the button to switch between modes doesn't have a very positive click and with thick gloves on, it is difficult to tell if you have pressed it or not. second is, and it is nothing to do with the light's design, when i'm honking out of the saddle,my face is forward of the light and so i have to keep looking up to avoid being blinded. time to fashion a little hood i reckon. for the lamp, not me. second new goody was a bike burrito that now hangs under my brooks and carries a tube, spanners, allen keys, tyre levers &c. in the kind of style that no black plastic pouch from topeak or the like could ever do. buy one. support a tiny business that had an idea and went for it. bikeburrito.blogspot.com/2008/12/bikeburritothe-movie.html despite my goodies, i still managed to fall off today. on my way home from work, a road was closed and i had to take to the pavement. i made the classic schoolboy error and mis-judged the step height and the front wheel, rather than crossing the curb, carried on in a straight line. my body weight was already heading in an opposite direction. i fell to the ground doing perhaps 15mph. my fall was stopped by a dry-stone wall to the hip bone. i've taken skin off my knee and shoulder. my hip and ribs are bruised up and my left wrist is turning grey/purple. the bike was fine. ironically, the thing that stopped the bars spinning round and denting the top tube was my new light! another reason to buy one... maybe
