Lens-Artists Challenge #357: Into the Woods

This week it’s the turn of Egídio of Through Brazilian Eyes to host the Challenge, and his theme is ‘Into The Woods‘. He says, ‘I briefly mentioned the Japanese expression shinrin-yoku in a post about national forests … a concept that was developed in Japan in the 1980s as a form of natural therapy and stress relief, or immersing oneself in a forest atmosphere. It is a way to allow all your senses to experience nature mindfully.’ Egídio continues, ‘this week’s challenge is about how you [practise] ‘forest bathing’ in your corner of the world. 

Regular readers of my blog may have noticed that the woods behind our house feature regularly in my blog posts. Whether it’s testing a new-to-me camera, or practising a new technique, or just going for a walk to relax or work off a heavy lunch, I’ll always head off for a ‘walk around the block’. For this Challenge, I’m taking one of my favourite cameras, the Olympus Camedia C-100 digital camera into the woods. 

The Olympus Camedia C-100 is a 1.3-megapixel CCD sensor with a fixed-focus lens released by Olympus in 2001. It’s fully automatic, which means that you can make next to no changes to the image you are taking, like monochrome mode for my beloved aerochromes. It’s a ‘point-and-shoot’ camera, and the sliding lens cover means that I can’t fix a filter thread to the camera, so if I want to make trichromes or aerochromes then I have to hold filters over the front of the lens, and sometimes the surround of the filter, or my stubby fingers, get into the frame.

The unique feature of this camera is that the sensor is failing, and I reckon that it’s overexposing by around 10 stops. Without any filter the images are completely blown out, but I’ve found that with a cheap Neewer ND2-400 variable ND filter on its maximum setting the vastly overblown natural images are made much more legible. It’s still a little overexposed on bright sunny days, but in overcast weather or in shadow the results are quite ‘good’.

I took the Camedia C-100 on a walk around the block, along with a tripod and a collection of filters. My intention was to try to make some digital trichromes and aerochromes, with red, green, blue, and infrared filters, but looking at the images from the red filter I reckon that the sensor has deteriorated even further and it seems to be even more infrared-sensitive. This did actually have some benefits in that red/blue channel mixed images came out wonderfully, but the images are now full of artefacts. Of course, I’m perfectly happy with that, the more glitchy this camera becomes, the better.

Around the fields behind our house, the woods look as they used to, but now, the once thick eucalyptus woods have been cut down to make way for heavy duty power lines for the long-promised high speed rail line between Lisbon and Madrid. I can still derive a lot of pleasure from the woods that remain, but now I just have to walk a little further.

Themes for the Lens-Artists Challenge are posted each Saturday at 12:00 noon EST (which is 4pm, GMT) and anyone who wants to take part can post their images during the week. If you want to know more about the Challenge, details can be found here, and entries can be found on the WordPress reader using the tag ‘Lens-Artists’.

A Diamond In The Rough? How A Plan For A Full-Spectrum Conversion Went Astray

I’ve been doing a fair bit of film photography just lately. There’s a new Shitty Camera Challenge coming up in June, and my participation in the Frugal Film Project with the Rapid format Welta Penti II led me down a Rapid film system rabbit hole that I don’t think I’ll ever escape from. But there’s always a technique that’s near and dear to my heart, making digital aerochromes, and sometimes the desire to produce a digital aerochrome can be quite overpowering. 

If you’re not aware, ‘back in the day’ Kodak made a colour infrared film stock called Aerochrome. It would produce the most amazing looking infrared images where vegetation, which normally comes out white with black and white infrared films, would appear shades of a lovely rich red. Sadly, I never got to use Aerochrome, and Kodak withdrew the emulsion in around 2009. However, there is an alternative. 

Originally developed (no pun intended) for use with black and white infrared film, Joshua Bird devised a method that mimics the look of Aerochrome film. Using green, red, and infrared filters, Bird made an infrared ‘trichrome’ that really is a good reproduction of Kodak’s old film stock. Of course,  I’m not really in a position to use black and white film, and I’m impatient, so I came up with a solution that uses Joshua Bird’s technique with digital cameras. 

The slight snag is that the best digital cameras to use with this technique are older CCD sensor cameras, and not the CMOS sensor cameras of today. Fortunately, there are plenty of old point and shot cameras around, and here in Portugal an excellent source of cheap digicams is the Computer Exchange (CEX) website. In addition to specific models, they sometimes offer ‘generic’ digital cameras for just a few Euros, and whenever one appears on the website I am tempted to buy it. After all, the most I’ve paid is about 5€ and with postage I can get a working digicam for less than the price of a pint in the UK. What can go wrong?

Of course, you don’t actually know what you are going to get, as apart from the resolution of the camera in the description the rest of the website entry is also generic, even the image of the camera. That said, of the several ‘generic’ cameras that I have bought from CEX they’ve mostly been from reputable manufacturers, there’s never been a fake Canon or Nikon, and sometimes I’ve received a real gem, like the Samsung Digimax U-CA3 that cost the princely sum of 1€ and produces the most wonderful digital aerochromes. 

So I had this urge to pick up a cheap digital camera and convert it to full-spectrum so that I can make some digital aerochromes. This involves taking the camera apart and removing the infrared cut filter that is fitted over the sensor.  You can always use an uncovered camera, especially ftom the noughties when the cut filters weren’t as efficient as they are nowadays, but removing the filter is always better,  and besides it means that you can take infrared images hand-held.

Anyhow, last weekend a 7MP ‘generic’ digital camera appeared on the CEX website for 4€, and yesterday the doorbell rang. It was the postman with a small envelope from CTT (the Portuguese postal service). Bringing the pack inside, I was completely surprised with what I found: a Beautiful little Sony CyberShot W17 in its faux leather case. OK, it’s a little like a brick in its design, but I knew instantly that there was no way that I could bring myself to tear this one open to remove the cut filter.

First introduced by Sony in 2005, The Sony CyberShot W17 is a 7.2MP digital compact camera with a 7.9-23.7mm Carl Zeiss Vario-Tessar lens. It has various automatic exposure modes, but can also be used manually, although I haven’t figured out how to do that yet. In the early noughties, camera manufacturers hadn’t standardised on the memory storage system,  and Sony was no exception. The W17 uses the Sony Memory Stick, a proprietary storage format that uses a long, thin plastic card. These are not that easy to get a hold of nowadays,  but fortunately, this camera included a 256MB Memory Stick Pro (a shorter version of the Memory Stick) and a Memory Stick adapter. I couldn’t actually believe my luck, as often as not these are all stripped out of the devices and sold separately. 

As well as a few normal shots in colour, I set the mode to black and white and took some images with colour and infrared filters to make a digital aerochrome. Back home, I downloaded the images from the memory stick onto my laptop and fired up GuIMP photo editor. Immediately I could see that the infrared response of the sensor was really good. My method for making digital aerochromes, from the article by Joshua Bird, used the digital images taken with infrared, red and green filters. The images were layered as red, green and blue layers, respectively. The blending mode for the red and green layers was set to addition and the results were spectacular! With beautiful pastel red vegetation and natural looking buildings and sky.

All in all, the Sony CyberShot W17 is a lovely little camera. The results are clean, if nothing special, but the infrared response was delightful. I’m definitely not going to modify this one for full-spectrum, though, so it looks like my search for a cheap noughties point and shoot camera just for conversion will have to wait a while.
