  1. Monthly Links for April

    As usual in this month’s collection of links, we’ll start with the hardest stuff …

    Science, Technology, Natural World

    So how many of the purported priest holes are actually what they’re said to be? [LONG READ]

    Samuel Pepys was, in many ways, a very naughty man – even to the extent of concealing letters about being offered an enslaved boy as a bribe.

    London

    Matt Brown of Londonist has taken a look at the origins of some of the City of London’s street names.

    Matt Brown is also creating a coloured version of John Rocque’s 1746 map of London. Here’s the latest section covering Chelsea and the King’s Road (above).

    Food, Drink

    Here’s a quick look at some of the factors which produce the myriad types of tea.

    Lifestyle, Personal Development, Beliefs

  2. Parakeets

    These birds are ridiculous! This morning, about 09:15, we had a garden full of ring-neck parakeets (Psittacula krameri from Northern India): 26 of them sitting about the trees and on the almost empty feeders; in the rain. And that’s the ones I could see! And it wasn’t just parakeets, the full count was at least:

    • 26 Ring-neck Parakeets
    • 2 Magpies
    • 2 Woodpigeons
    • at least 1 Squirrel
    • and an uncountable number of various species of tit (blue tit, great tit and maybe some coal tit).

    Here’s a quick photo of some of them (taken through a dirty window) to prove the point – I can count 22 in this photo! [Click the image for a larger view.]

    I know many people don’t like these parakeets: they’re an alien invader, prolific, noisy, and supposedly keep the smaller birds off food supplies. However we love having them around. No, they’re not native. Yes, they’re noisy. But they are comically acrobatic. And judging by our garden observations they certainly don’t deter the smaller birds – if anything is guilty of that it’s the squirrels.

    There’s lots more on these parakeets on the Natural History Museum website. Let’s celebrate them as a colourful and fun addition to our environment.

  4. January Quiz Questions

    Each month we’re posing six pub quiz style questions, with a different subject each month.
    As always, they’re designed to be tricky but not impossible, so it’s unlikely everyone will know all the answers – just have a bit of fun.

  5. World Pinhole Photography Day

    Bah! Humbug! to the London Marathon. Much more interestingly today is World Pinhole Photography Day – always the last Sunday in April.

    Before we had lenses for cameras, and indeed before we had photographic film, it was possible to view a scene, and project it onto a wall, using a tiny aperture. This was the camera obscura used by artists since ancient times.

    Pinhole Dandelion
    (Click all the images for a larger view.)

    Once cameras and the photographic process were available, it became possible to do this trick with a tiny pinhole instead of a lens. Needless to say the results are not sharp, as they would be with a lens, and because of the tiny aperture exposure times are much longer than we’re used to these days. But the smaller the pinhole, the sharper the image and the longer the exposure needed.

    Nevertheless it is a fun, and often instructive, technique to try – and these days it’s very easy with (digital) SLR cameras. All one needs is a pinhole – and you can make that yourself! (If you hunt online there are people who will make a pinhole for your camera; or even sell you a bespoke pinhole camera.)

    Pinhole Red Deadnettle

    There are a number of “how to” sites on the internet. Basically you need only a spare camera body cap and bits and pieces you will already have lying around, like an empty drinks can.

    A couple of years ago I made a pinhole for my Canon dSLR following the instructions on wikiHow. It was a bit tricky for me, with my ten left thumbs, but after three or four attempts at making the actual pinhole (in a piece of drinks can) I made something which works adequately if not brilliantly.

    Pinhole Lilac Bush (from below)

    Setting up and taking pictures is easy enough. Fit the pinhole (body cap) to the camera and mount the camera on a tripod.
    Set the camera to manual and ISO 100 (or slower). You can’t adjust the aperture of the pinhole, which will be tiny, so you then have to experiment with exposure times of 10-30 seconds (compared with the normal 1/100th or faster) in good light; longer in poor light or night. Use a remote control (or the camera’s timer delay). Now experiment.

    So today I found my pinhole, and had a wander round the garden to see what looked likely to make a decent photograph. The images here are the best results (slightly colour enhanced). For comparison the following final two images are of the garden with a pinhole and with a normal lens on the camera – I reckon for a piece of crude homemade old technology the pinhole doesn’t do a bad job.

    Pinhole View of Our Hairy Garden
    The same view of our garden with a proper camera lens!

    Of those four pinhole images, I think the first, the dandelion, has worked the best. What does anyone else think?
