So, it’s been a few days since I tested the Sprocket Rocket with a roll of HP5+ and although the camera has been back on the shelf whilst I’ve pursued my nocturnal project I’ve still been cogitating quietly on the matter behind the scenes. Key questions in my head have been, will my metering plan work with the Kentmere 400 and should I wait until the February roll to find out?
My reader knows that doing nothing is rarely my answer to matters photographic however, especially when I have the means for doing something so readily available. I accordingly made up a short roll of the Kentmere 400 and loading the Rocket once again headed out.
Now, I’d already decided that I’d assume the camera was f11 and 1/200th (it could equally be f22 and 1/40th of course) and that I’d meter accordingly. The other question was at what speed to rate the film. I’d done some more online research and also consulted friend and technical consultant Andy (@holga_pics)and had decided to rate the film initially at ISO 200 although I might even move to ISO 125 at some point. A handy scrap of paper enabled me to check my logic (see below) and if the meter reading was 1/30th then I’d need seven shutter actuations to build the necessary exposure. Unless I took a tripod then I’d probably be looking at ICM [(un)intended camera movement perhaps?] given the typically grey day here in West Yorkshire.
I wasn’t looking for portfolio images but for the answer to the question “is it worth pursuing this quest for another 12 months?” As Andy had said:
The film is sub par and the camera is junk, so you’re trying to make a silk purse from a sows ear.Sir Andy of Holga
In fairness I have to agree. The roll I put through the Nikon F801 was perfectly acceptable; not on a par with HP5+, why should it be, but OK. The camera is plastic, made with virtually no noticeable quality control that I can see and will almost certainly be donated to an unsuspecting victim once the December roll is in the tank. Form an orderly queue please!
I developed the film in Perceptol, freshly made stock solution, for ten minutes which is the recommended time for the film exposed at 400 ISO. The resulting negatives were an improvement but decidedly lacking in contrast. Perhaps this is a feature of the film but regardless as I’m digitising the negatives for this project it is not an issue. Every exposure was made using the principals outlined above. Where the metered exposure was shorter than 1/250th I gave just one shutter activation but on the whole erred on over exposing. Only one of the fifteen negatives exhibits any over exposure so I’m heading in the right direction. For February I will rate the film at 125 and develop in stock Perceptol I think.
I’ve now used six rolls of film testing this set up, including a roll of HP5+ and a roll of Kentmere 400 that I sent to a friend for an independent view. I have nine further rolls made up and stored in the cellar which should see me through until the October roll. There should be enough of the bulk film left for me to make rolls for November and December once I have a couple of donor cassettes available!
Next update will, hopefully, be in February.
