The ones that got away

click photo to enlarge
Photographers are like fishermen: they dwell upon the ones that got away. I can still see the shot I missed when an enormous sheet of agricultural plastic, more than 100 feet long, blew past me and floated over a bungalow, twisting and turning in the air, a surrealistic sight that I came upon when I was without a camera. And the photographs that I've missed when driving along roads where stopping was dangerous or forbidden are too numerous to mention. However, the failure to get photographs on these occasions can be be easily forgiven; you simply feel that fate, circumstance - call it what you will - were against you. What's harder to deal with is when you see a shot, consider how to secure the best that it offers, and still don't end up with the photograph you wanted. Today's two images are examples of this phenomenon.

We were walking through some trees at Woodhall Spa, Lincolnshire, when the tip of a beech tree branch hanging low against a background of foliage caught my eye. There was no light coming through the trees behind, so I knew there would be no circular highlights to detract from the serpentine line of the twig or the delicacy and fine colours of the leaves. I opened the aperture to f4.5 to blur the background and mounted the 70-300mm lens to provide a longer focal length to further increase the blur, then took the main shot at 141mm. The composition and the light through the leaves is just what I wanted. However, I could see from the LCD that the background could do with more blur. So, I took a second shot. For this one I increased the focal length to 300mm. Then, knowing that the depth of field would be very shallow, opened the aperture to f5.6 (hardly worth the change). I took my shot looking carefully at the background, and was very satisfied with it. However, when I came to look at both shots on the computer I realised that I'd missed my composition on the second shot even though I'd got my background as I wanted. If I'd been paying better attention I'd have got the composition of the main photograph with the background of the smaller one. My next chance of that particular confluence of details is probably next autumn!

Blogger image backgrounds and those rings

click photo to enlarge
Many people have increasing concerns about the power, reach and intrusiveness of Google. Blogger is owned by Google and is one of their many free offerings. From the time I started using it in 2005 there has been the facility to add advertisements to a Blogger blog and for the blogger to make money (usually very small amounts) from so doing. The Google word for this is "monetize", a horrible construction. I've never had the desire or need to do so, and this blog is advertisement-free, a situation I don't foresee changing. Of course part of this process involves Google making quite a bit of money from the advertisements, based on key-words, that are placed in the blog. Consequently I suppose that by not using advertisements I'm taking advantage of Google's benevolence. But, they don't seem to mind so neither do I.

I do wonder, however, if Google has its ear closer to the ground than even the conspiracy theorists imagine. In the Comments of a very recent post there was an exchange of views concerning the effect of the white background that accompanied the enlarged view of a photograph. On some subjects it doesn't work very well, is overpowering, and is at odds with the black background of the blog pages. Well, quite soon after that date the background to enlarged photos was changed to black. Were Google listening in, or was it one of the planned incremental changes that are regularly rolled out? Whatever the reason - and it hasn't been trumpeted anywhere by Google that I've noticed - I like it. And, at the risk of pushing my luck I'd like to suggest that it be retrospectively applied to older posts too.

All of which has nothing to do with today's photograph of abseiling workmen on Tower Bridge in London. I spotted them as we walked past the other day. They appeared to be doing something electrical, perhaps installing the enhanced lighting that will illuminate it during the Olympics. I read that, in addition, a set of large, illuminated Olympic rings will hang from the bridge during the Games. When I first heard of this proposal I tried to imagine a worse combination of the insensitive and the tawdry. But I couldn't.
