Straight

One of the curses of the wide angle lenses is the damage you can do to verticals, as discussed recently. You can bend your pictures just as much by aiming the camera downwards, and here's an example from the Tate Gallery in St Ives. This modernist building is worth a visit for the minimalist interior. I'm not so certain about the Art, but the building is nice...




I am willing to accept this example of converging verticals as it stands because it represents the view down the stairs.  However I have also straightened it using the excellent PTlens plug in. This can correct perspective distortion as we see here, plus it can sort out Pincushion and Barrel distortion and Chromatic aberration and Vignetting.

I'm glad to report the Zuiko 11-22mm wide zoom suffers from very little of these failings, but nothing can prevent the photographer from tilting the camera... Here is the straight version. Which do you prefer?

Wicker dam

Well this is typical of Britain. We used to do things well. Sheffield steel was the envy of the world, people would queue round the block for the chance to buy a nice nylon shirt from Marks and Spencer or a brand new Vauxhall Velox. And now? Now we try to keep lake water in place with a pair of wicker fences.  It is this sort of woolly thinking that could lose us our Empire. You mark my words.

What's This?

What's this little thing then eh?   Well, let me tell you a story... We changed cars recently. The replacement car is awfully modern and features a USB port.   A USB port.. really? What is that for, do you charge your phone on it? No, in fact you connect your iPod* to it. However it will also accept a standard memory stick and play mp3 music files from folders directly. Now that is a cute trick, as I don't own an iPod*. However, I wouldn't want a conventional memory stick poking out of the car for all to see, so I set off in search of the smallest stick I can find. Here it is, a Busbi Mini 4GB stick. In the background are just some of the CDs and tapes I transferred to it. Even this version looks like it will hold about 40 albums, which is all we will need in the car. So, this leads me to a nostalgic moment. In order to convert the tapes to mp3, I had to record them on the PC, cut 25 minutes of audio into individual tracks and export as WAV

Pompeii

No trip to the Bay of Naples is complete without a visit to Pompeii. This vast 270 acre site is almost too much to take in, particularly in the scant two hours we had with our coach guide. Here's a view of the Auditorium near the end of the visit. A chance to sit down and relax for a moment.  As always, click on the image for the full size version.   The plaster casts of the victims are a chilling and sombre sight in amongst all the ruins For a more relaxed and informative experience, I suggest Herculaneum, on the other side of Vesuvius. Unlike Pompeii, this was covered in volcanic ash and mud which created a anaerobic layer that led to the  preservation of wood and similar materials. Here is a panorama of the buried town that shows how far below the current ground level it is. Most of Herculaneum is under the more recent town. It was lost for centuries: Historians agreed the it and Pompeii were on the coast, but they were digging in the wrong p
