At home I have a fairly good backup scheme for ensuring my main PC and the wife’s laptop have their critical data stored on at least a couple of other disks. In addition to using cross-copying each other’s content, I have a second hard disk in the main PC just for backups and an external USB disk for backing this up to. I also have a few hundred megabytes of useful everyday stuff synced across machines and into ‘the cloud’ using the excellent Dropbox utility. So I’m pretty well covered against hard disk failure, and my critical files on Dropbox are insurance against houshold disaster.
Yet I’ve always had this nagging feeling at the back of my mind about the 80+Gb (and growing) of other data such as photos, videos, and general stuff that falls under the category of don’t-look-at-much-but-don’t-want-to-lose. While the hard disk duplication may cover me against hardware failure, and in fact did so a couple of years ago, I retain a nervousness over fire, theft, flood, or enormous wine spillage in my IT area.

Light trail
The Christmas break this year gave me the opportunity to play around a bit with long exposure shots. The bottle picture on the right is the best of my experiments, and is a single 20 second exposure with minimal post-processing. The set-up was easy – just an empty bottle of wine, a darkened room, a blue wooden table, a tripod, and a blue LED penlight.
The idea was that once the shutter opened, I would move the penlight torch around the bottle in what would hopefully be a spiral shape. The movement produces the bright light trail, but also leaves enough light to illuminate the base and some of the bottle – in particular the label.
The trickiest part of the setting up is to determine the focus point. You can’t use the camera’s automatic focus as there is not enough light in the scene for the auto-focus system to work. While you could just switch to manual mode, on the basic SLR I used – a Canon EOS 350D – manual focusing aides are a bit limited. Instead I switched the main room light on, used the camera’s auto-focus to pick out the bottle, and then switched the lens to manual focus mode, being careful not to disturb the lens at all. I then killed the lights to start the shoot.

I have been in Round Table for a few years now, and really should have known better than to admit I worked in the computing industry – I got “volunteered” to manage the existing website. Me and my big mouth… But after a while I decided I would like to modernise the rather traditional and static website that I had inherited. The main constraints of this revamp were (a) it had to be cheap, and (b) I’m no web designer! In other words – no money and no talent. The reason for “cheap”, by the way, is that Round Table is a voluntary service organisation – we have a good time doing all sorts of things, but primarily we raise funds for charity and help out in our community. For more information on Round Table and what we get up to, follow this link.
So my challenge was how to put together a community website using – ideally – one of the free or very cheap services out there “in the cloud”. It had to look reasonably good, and also include an email infrastructure to help keep the 200+ members in touch.
This article describes the software and services used to create and manage a modern community website, and the reasons for choosing them. I describe the basic steps to get up and running quickly, including optional links with Twitter and Facebook. There are doubtless a number of alternatives, and I make no claims to my solution being the best or being suited to the needs of everyone. But in explaining the choices made I hope to at least help guide those who want to do something similar.

Peak District exposure blend
Following on from my previous post “Something from nothing“, this image uses a different technique to blend an overexposed sky with a detailed foreground. I nearly called it “Something a bit better from a little bit more”. This post is shorter than the earlier article, and hopefully less coma-inducing as a result.
The photo was taken from Heggar Tor in the Derbyshire Peak District last April in the early evening. This time I had the benefit of my Canon EOS 350D digital SLR, and captured in RAW format, which gives much more to play with in post processing. I also used slightly different software – Photoshop Elements 5 (or possibly 6 – I forget when I upgraded). The editing process still uses layers, but this time rather than overlay them using masks, combines them using blend modes.
The resulting image won’t win any prizes, but I rather like it. It may not be too obvious from the small image here, but if you click on the above image and select the larger version (via the “All sizes” button) you should be able to see some of the fine detail of the rocks and lichen.

This image came out of nothing, and I’m not sure if it is cheating or not. With a pretty poor original photo (see below) I changed the colours, messed with the contrast, blended different parts together and airbrushed out some bits that were spoiling the shot. Which got me to thinking: at what point does photo enhancement fake things too much in an attempt make up for poor camera technique?
Here I describe how I put this image together from an original low quality shot. If nothing else it may help people who want to do similar things using their photo editor. I’ll leave it to the reader to judge whether I should have just taken a better picture to start with.

This is one of my favourite photos that I took last year. After the heavy rains in the summer, I took my son down to the local nature reserve in his full waterproofs, knowing that big puddles would be too much of a temptation for a five year old little boy.
As you can see in the next picture, he got quite enthusiastic!
If you click on any of the images you will be taken to the original picture on my Flickr site, and from there browse all the exposure and timing information. Both images are slightly cropped, but are otherwise unretouched.

About a year ago I wrote about the Photosynth technology from Microsoft that creates 3D spaces from collections of photographs. At the time it only worked with a few sample data sets created by Microsoft, but there was a very nice demo to download and it was a pretty exciting piece of tech. Just a few days ago Microsoft released a full version that allows you to create your own “photosynths” by uploading collections of photos.
I just had to have a go. The image above shows a screen-grab of the Photosynth viewer with some data that I took.
Read on for more on the new release, how I got on with it, videos and links to the 3D scenes that I created.

Setting off, 5pm Friday
In this second article on my recent 3 Peaks challenge I describe the hikes themselves and the transits between the mountains. See Part One for a description of the challenge.
My personal times were:
| Mountain | Start | Summit reached | Back at base | Distance |
| Ben Nevis | 5pm | 7-50pm | 10pm | 10 miles |
| Scafell Pike | 4-30am | 6-30am | 8-30am | 6 miles |
| Snowdon | 1-45pm | 4-10pm | 7-30pm | 8.5 miles |
So as you can see I did succeed and completed it – I got to the top of Snowdon in a shade over 23 hours. I was a little disappointed not to get down again within 24 hours, but as you will discover when you read the account of each mountain, I just count myself lucky to have even finished at all, irrespective of times.
