Grey Days

Saturday

We knew it would be raining on Saturday morning and sure enough, when Rufus persuaded me to take him out into the garden for his pre-breakfast stroll, it was drizzly. After a brief discussion, we decided it didn’t matter. So we had breakfast and then off we went to Rhossili, up we went onto Rhossili Down, it rained, we got wet and some of us got muddy paws and heather tangled in their fur. We explored the old radar station, watched a huge flock of sheep depart en mass as we approached and made friends with several horses and a couple of foals.

Rufus had to have a shower when we got home. He doesn’t like the shower but I think it’s more about dignity than dislike. I make sure the water isn’t too hot and the spray isn’t too strong. He made a show of trying to escape; he understands the word shower and I spent 5 minutes rounding him up. In the end, he curled up on his bed and pretended to be asleep. But once in the shower, he wasn’t too bad. He tends to grunt and huff a lot, but if he really wanted to get out he could. Instead he allows me to wash under his paws and under his chin. The water was brown running off him, and I probably could have planted a small heather patch in the garden with all the bits that came off him. I don’t have a selection of hair care products, so he had to use the same Head&Shoulders Itchy Scalp hair shampoo that I do. Other shampoos are available and Rufus doesn’t endorse any particular products.

Sunday

Back in the day, I went to the Polytechnic of Central London. As soon as I left, they changed the name to the University of Westminster in the hope that I wouldn’t return and that they could purge all records of my existence there. In fact, I did pop back in December, but that’s another story.

I enjoyed my three years in London. I liked being self sufficient, I liked being in a place that really didn’t seem to stop, day or night. I was fortunate enough to live for the first year in halls of residence just off Oxford Street. It was fantastic. The course I took – Photographic Sciences – was an eye opener and confirmed my interest in all things photographic. Although I did become a little jaded at the end and took a break from photography (ironically, just as I started working as a photographic technician in the local further education college).

The things that held my attention most on the course were the experimental and technical photographic techniques. Some of the most interesting techniques for me were macro, high speed photography and filming, and infrared photography. This was a long time ago and everything we did was on film and we developed everything by hand. I remember right at the end of the course being shown a new little chip that was one of the first image recording sensors – the forerunner of today’s digital camera innards.

Since I left college, I’ve carried on with some of those techniques as best I could. While I was still using film, I used to use Ilford’s SFX emulsion. It had an extended red sensitivity that, with the right filters, could give some infrared effects. It took some handling though (you couldn’t load it in daylight) and gave grainy results. It was great! I got back into macro photography a couple of years ago, and I bought an infrared enabled Fuji S3 just over a year ago. I’ve used it a lot since, experimenting with the effect and finding the best combination of lens, exposure and subjects. I love the effect and have posted some results here int he past.

Last week, after some weeks of trying, I realised that no one wanted to buy my old D300 body. So after some research, I contacted Protech in Uckfield who quoted me a good price to convert the D300 for infrared photography. The company was great. I had a conversation with Jo, who gave me some advice about what lenses could and couldn’t be used. I sent the cameraq off at midday on Thursday and around 11am on Saturday it was back with me. A combination of a fast turnaround at Protech and great service from Royal Mail made that possible. Thank you both.

So for the rest of the weekend, apart from last night’s gig, I’ve been playing with the D300. There are a couple of immediate differences between it and the S3. The main one is that the infrared filter is different. GEEK ALERT – Do not read further unless you can handle nanometres without any side effects.

The filter on the S3 blocks light with wavelengths shorter than around 665 nanometres, that is, light in the visible part of the spectrum. In practical terms, (because filters aren’t perfect) this means that some visible light is recorded and the recorded image before processing appears a deep red colour. The filter in the D300 blocks light from about 720 nanometres, which means much less visible light is recorded. The recorded image takes on a more purple hue. The D300 allows for a custom white balance to be applied, which means that the review image on screen is very close to the black and white final image I would be looking to get. The D300 is a more advanced camera, it has better resolution and low light capability and is a more robust camera. The metering and focussing is better, too.

GEEK ALERT OVER. It is safe to continue reading.

So I’ve been trying lenses and subjects and all sorts of combinations to make sure it’s all working well. And it is! Bearing in mind that it’s been raining non-stop for the last two days, I think I’ve got some interesting shots. I’m certainly happy with the camera’s performance. The only think I haven’t been able to test properly is a sunlight landscape. Below are a few of the test shots. They’re not meant to be works of art.

  1. With a High Red 590nm or 665nm conversion, the camera sees some visible light and also infrared light. Because your lens is being asked to focus over a wider spectral range, you may have a slightly softer picture or have to compensate with smaller apertures. The is because most lenses have a different focal point for the visible than for the infrared. Depending on your lens, focal point and aperture, you will need to determine if you need to make any manual adjustments.

    • Thanks for that.

      So far with the 665 conversion, I’ve had no problems with any of the lenses. It’s too early to compare results with the 720 conversion, and in additions, the cameras are so different in terms of capability that a direct comparison wouldn’t be fair.
