Processing C41 Colour film in Black and White Chemicals.

My local Pound store has started selling the Geek 10 exposure colour film for £2 a roll.

Though it is only £2, the 10 exposures, then paying for development means it doesn’t actually end up being very economical as Kosmofoto points out. But what if you could develop it as a black and white film? Would that make it a cheap film to test cameras? At the very least, it would make a good experiment.

So, a little more about the film, in case you want to use it as a regular colour film. The ten exposures is literally that. I managed to get 9 out of mine once I had loaded it. To get ten you would have to be very careful while loading, or load in the dark. The cassette feels very cheap, a plastic affair that is tricky to open in order to process the film. I had to rip mine apart. The naff cassette also seemed to hinder the movement of the film through the camera and initially thought I had misloaded it. I found using a film picker impossible, hence the ripping apart option. The actual film inside is rebranded Fujifilm C200, here is another great blog with details about that.

I did some research about cross processing colour film as black and white and there are a few articles online. On the whole I didn’t find anything really substantial about using the developing chemicals I had. I have recently been using Kodak D-76 after switching from ilfosol 3. I did find one chat thread that way down said try a development time of 8 minutes at 20 degrees. But most things I read said don’t do it or it was a waste of time.

So ignoring all the naysayers I went for these development details.

Chemicals used: Kodak d-76 at full strength 1:0
Temperature: 21 degrees
Development Time: 8 minutes (with stop=30 secs, fixer=5 minutes)

Of course the emulsion is on a very orangy base that will affect scanning, but was there an actual image to scan after developing? YES!

The film was quite dark due to the plastic film base, but it scanned quite well considering. The initial scans were quite flat, but I processed all 9 exposures through the Snapseed phone app. To be fair, recently the weather has been rainy and dark so even a “real” film would have struggled.

Some of the shots came out quite well, others were underexposed. Overall, they weren’t so bad. What if I took the film out on a bright day and overexposed the film? The next test? Once the weather changes I will try that and update the post. Either way it was not a complete loss, at £2 a roll it is another option.

Minolta Capios 25 and Home Processing c-41

I can find nothing about this camera online. The few bits and pieces are in Japanese, the only English sites were about selling one. The prices range from $1-$100. I paid $3 for mine and I think it is worth so much more. I have an Olympus Mju and that is always lorded as an awesome point and shoot, which it is. This camera worked just as well for me with comparable options and for a fraction of the price. It also feels smaller and lighter.


According to this website this camera was released in 1995 for a suggested retail price of 45,000 yen, which even today is a very big price for a point and shoot. The lens zooms from 28mm – 70mm with apertures from F3.5 and speeds up to 1/500 (at 28mm). The focusing system is 3-point multi-beam infrared active autofocus 0.5m ~ ∞ with macro mode 0.4m ~ 1m.

That means the aperture is not as wide as the olympus, but for the price difference I would be happy. Anyway, thank goodness for Google Translate. I think this is an awesome camera.

For this film I decided to try processing the film at home. I have already processed black and white, so why not colour. I found a kit on eBay which said I could process at 24 degrees C. The usual temperature of 38 degrees is supposed to be hard to maintain. I find this a bit odd as the developing time is just 3.5 minutes. at 24 the developing time is 13.5 minutes…much longer to maintain it.

I felt this camera was working well, it made the right noises, so picked this film to try it out. Here are the results.

Well, the camera worked very well. I love it. But I am not too sure on the processing. The photos are ok, but the tint is an indication that all was not well on the processing front. On the other hand they came out better than the local shop I used last time. So I think I will have another go at some point. As the chemicals do not keep for a long time unlike the black and white ones, and they cannot be bought in regular shops in Japan…it will have to be soon.

So keep or sell? Well I doubt I will get what I think it is worth so I am tempted to sell the Olympus Mju and keep this one. I will ponder this for a little while before deciding.

Oh and these photos were taken in Tsurumi at Sojiji.
