Old Light Meter

[Acidjazz]

Hi

I would like to ask about help.
In my old father's suitcase I've found something which like like as light meter.

It looks like suitable for yashica linx or another camera with out build in light meter.

I know that is light meter🙂 but I have no idea how I can use it.
Maybe somebody know how is it ?

Best regards

It's a selenium-cell light meter. Just point it at a light source and the needle will tell you what settings to use, based on the ASA and shutter/aperture values you dial in. If the needle's not moving, though, the meter's dead and probably can't be rescued.

Yes I know, this light meter is working but I have no idea ho I can use it.

The aperture scale is against speed scale 🙂
I've compared to another LM like as Sverlovsk-4 or Sekonic -398 but I have no idea how I can read exact exposure 🙂

Line up the desired shutter speed with the film ISO/ASA. Then read aperture from meter.

Dear Jarek,

The ninth illustration here may help:

It's a built-in meter, but the layout is much the same. The meter is set to 15 DIN/25 ASA and the red 'OPEN' arrow is set opposite the needle position.

Cheers,

Roger

I have this exact meter. It's quite nice actually. Not the one to use in low or ambient light, but fine for outdoors. Simply match the shutter speed on the outer ring to the film speed. Then the needle tells you what to set your aperture to. DON'T get confused by the long line on the outer dial between 60 and 125 that points to "LV/ASA" lettering. Ignore it. Just match up the shutter speed you want to shoot at (60, 125, 250, 500) which corresponds to 1/60th of a second... 1/500 of a second to the film speed 100, 200, 400, 800.

In the example in the 3rd picture, it's telling you that if you're shooting 1/125 with 100 speed film, 1/250 with 200 ASA, 1/500 with 400 speed film, and 1/1000 with 800 speed film, you should set your aperture at f2.8(approx) given the lighting conditions.

Thank everyone for help.

Of course, like usually, solution was very close but I couldn't see it 🙂
