LC-A and Colored Tape


What consequences does colored electro tape have on my shots?

I knew that taping the lightmeter of the LC-A with black electro tape extends the exposure time to nearly infinity. That is a good way to make longtime exposures light painting,… So I tried it more in low light conditions to have a kind of B-setting.

Now I was wondering if the different colors extends the exposure times differently. There is white tape, green, red, blue, yellow, sometimes brown,…

So I took my LC-A, Hema 400 Color Negative Film, a tripod (to have the same shot and with the same conditions) and six different tape colors, I looked for different light conditions (indoors, outdoors, direct light, indirect light) and shot. To know where to tape, here are some (digital) photos and a scan of the tape, so you can see the different colors.

I made a certain order of what I thought will be a line of time-extension: grey, yellow, green, blue, red and black – and this order was always the same! This tape ( I think it depends on the material, too) let more or less light through and looking at the results, red wasn’t that dark, almost the same as green. The idea was not about taking “good” shots! It was only about the technique and different light conditions.
Here are the results and some explanations.

Twice the motive without tape and afterwards the tape-order. Shot 8 (with black tape) is totally overexposed and burned shot 7 and 9 (next motive). As there was no direct light (sun in the back) I had to lift my finger after a while shooting the black tape.

The next shot was taken against light. Shot 1 (so # 9 on the film) was burned by the overexposed shot before and was accidentally cut by the lab. Now shooting against a bright lightsource (sun) the black tape stopped automatically (after a long time, but it stopped without me lifting my finger). It is burned again.

Set number three is indoors with a light source (window) on the left side where the lightmeter is. There was no direct sunshine through the window, but I turned the camera, so the light that was there enough to be sensed by the lightmeter throug the tape.

Next was the same room but now with the window in the back, so again no direct light reaching the lightmeter.

A different light color (direct reddish sunset light) was the next attempt.

The conditions on these shots: A direct not that bright light source (lamp) and a window on the right side. I kept the infinity setting how I found out after shot 6…

Now I had the glorious idea of taking longtime exposures during night time. I was not patient enough so I did not wait till it got totally dark. My fault. So the exposure time was not only extended by the tape, but by the conditions, too. All tapes (I did not use black) made under these conditions the B-setting possible. That is something I really have to try again!

Realising my mistake, I turned around and took indoor shots with mid light.

Here I did not use all colors. The order is none, grey, yellow and red.

A set of selfportraits next to a train window, so the lighmeter more or less is direct in sunlight.

And finally landscape shots out of a driving train with 0,8m setting

    this is your last chance, neo. stick the blue tape on your lc-a and you'll get normal photos. but if you choose the red tape, i'll show you how deep the lomowall can goes. but remember. once you go in there, there's no turning back.
