Modifying your LC-A+ to Achieve ISO12

If you prefer to overexpose your ISO400 redscale film by five full stops in your LC-A+, you would want to override your camera's ISO setting to 12. But how? I have got the tipster for you!

Contemporary knowledge regarding redscale technique tells us to overexpose our shots by two full stops. However, I personally do not enjoy the outcome. Based on personal experience, often, the results are less than decent, as most of them still seemed to be underexposed. The tremendous hues of orange and red are simply irritating for me.

A couple of months back, I read an online discussion suggesting that in the case of redscale film, an overexposure of four or five full stops would yield more flattering results. The images are well exposed, and although there is still a hint of orange, the colors are more dynamic; blues and greens appeared! The sample photos that came with the discussion left a rather favorable impression in me.

However, if I will be using my LC-A+ with a DIY Redscale ISO400 film, that will only leave me with the option to overexpose the film by 2 stops. The LC-A+ can only be set to its lowest ISO setting which is 100. So, I tried to figure out a way to override such mechanism to achieve an estimate setting of about ISO12.
How? Let me tell you.

The ISO setting of the LC-A+ is based on the opening of the light meter. If I set the camera at ISO100, I can still trick the camera to think (if it does) that the available light is less than what is actually available. With this, the camera will expose the film a couple of stops more. And how did I trick the camera?

By simply covering the light meter with a translucent material to cut down the light registered by the meter. For this particular attempt, I used old negatives, particularly those portions which are blank. To achieve ISO25, just cover it with one layer, and if you double the layers, your camera now is operating as though it is set at ISO12.

How do I know it is ISO12? I don’t! But I think it is close enough. You can see below the test I have done using my Olympus XA (ISO200 to ISO25), and then the LC-A+ at approximately ISO12 (set at ISO100 and light meter covered with two layers of blank negatives).

Just let me know if you have any questions.

Enjoy!

    I was also thinking about writing this tipster using film negative to cover the light meter. I should find something else to write about now :^)

    Never thought about using film negative to cover the light meter, pretty smart, but like you said you weren't 100% sure. If you wanted to be sure you were precise on the ISO, I would try pieces of ND .3 Gel.

    @12_12 - I have. Used a rebranded Kodak Elitechrome 100. Got more of a magenta tone instead of orange. Very interessting. But I'm not quite sure which ISO setting i used. I need to scan those negs soon.

    @c41: It would be great to see the results of that!!!! I can imagine that the results can be very good using a similar technique (then maybe ISO200 slide film(?)) !!!

    may I ask something? lc-a+ minimum iso is 100 right? to reach iso 50 we need to cover the lightmeter with 1 layer of developed film and so on right? thus to achieve iso 12 we need to cover three layer of developed film

    @analogmonolog - I came to the conclusion that the 2 layers are enough to achieve ISO12, because when I compare the results with a photo taken by the XA set at ISO25, it was more exposed. One layer of developed film is closer to ISO25 than ISO50, as per my estimate.
