Camera Obscura
5/6th shoot - With Bonfoton lens
Keen to try out the new bit of kit (the Bonfoton lens) I was also keen to use a room downstairs. It feels that a lot of this type of photography is bedroom based, but I wanted to apply this throughout my house, so this would be an interesting test for both the lens and a ‘downstairs’ room. The first test was both a success and a failure at the same time. The (new) tin foil technique worked very well, and for a first attempt it went up super fast. The foil will easily overlay with a spray of water, and if a mistake is made, the foil can simply be peeled back and adjusted. This technique was not 100% perfect, but this was more to do with my application rather than the effectiveness of the material (tin foil). Once the foil had been applied it was simple to cut (using a sharp craft knife) around the (supplied) template, to create the aperture for the lens. I then simply taped the lens over the hole with electrical tape.

The technique of using aluminium (tin) foil for blacking out the room was both effective and quick. It is also cheaply available and (as it turns out) re-usabe.

The Bonfoton lens was fixed in place with electrical tape. The lens comes with magnets so that it might be fitted to a blackout blind, but I intended to use this at a number of locations and so improvised with the tape.

The electrical tape and the foil worked very well together and the tape was easily removed without damaging the foil.
The lens was a great improvement, with the projected (outside image) now looking very sharp BUT the fail aspect of this shoot now came down to my own tardiness. I need a good sunny day for these shoots to really work (which I had) but I procrastinated for so long that by the time I had the room ready, I had effectively lost any light, and my projected image had become a dark mess. This was frustrating as I am trying to get a combination of good light (a sunny day) and my sitters being at home, and I only had myself to blame. When I took the tin foil down I laid it as flat as possible to let it dry for potential reuse.

This test image from the 5th shoot shows the improvement in sharpness that the Bonfoton lens has given the projection, but despite (my own) best efforts in Abobe Lightroom the colour (due to the lack of outside light) was poor.
When the next opportunity to shoot arose I grabbed it and had the room set up very quickly. The tin foil that I had saved easily went back in to place and the projected image was considerably better.

I wanted to make the most of this opportunity to shoot, so I took a broad range of shots using both my own Sigma Art 50mm lens, and a Canon (L series) 24mm lens that I had borrowed from the university kit room for the duration of the easter holidays. I wanted shots of my partner and if possible I wanted a shot of her with our dog ‘Archie’. I would use the 24mm lens to take the portrait shots and then I would swap to my 50mm for some detail work. As I am (currently) working un-teathered this also involves some coming and going to review the images on my laptop. The good light however allowed me a good few hours shooting here BUT later in the day (to re-enforce the fail from the previous shoot) the sky clouded over and any good light disappeared.

My partner and our dog ‘Archie” sitting for a portrait. I used the 24mm for this shot and the distortion (particularly) with the dog bowl is quite off putting for me. The black board on the wall has been replaced by a clock which had hung there previously. Photo taken by Chris Arrondelle - Canon 5D mkii - Canon 24mm lens - f2 - 4 sec.

I was happy with the images I had caught and the performance of the Bonfoton lens. Getting the dog to sit still for 5 seconds was 50/50 so I had a few to work with. I was very happy with some of the detail shots, particularly the kitchen cupboards. I was also quite pleased with the Marja Pirilä inspired doors. Leaving a door slightly ajar gives a sense something beyond and I like the aesthetic that it gives to the image. To progress the project I would work the images up in Adobe Lightroom and show them to my tutors for feedback.
