This is as true as saying politicians and lawyers are models of honesty and integrity.

I have looked at HUNDREDS of old Selenium meters over the last 30 years and exactly TWO of them were still accurate. One was a Sekonic L-398M, a meter that was still in production at the time (the current version is the L398A) so it really wasn't very old. The other is the Weston Master V that I bought at great expense from Ian Patridge, a British man who restores old Westons by putting new metering cells in them, a necessity because virtually all of them are dead now.

I have had numerous people show me old Selenium meters that they claimed worked and it took literally 30 seconds of testing to show that they were quite inaccurate, despite still giving 'readings.' Every. Single. Time.

OK that does not change the fact that you are wrong generalizing like this. Lots of selenium meters even from 50's still work, and work well. I know, have at least 10 that do, even if I don't use them on daily basis. Surely their history of use/storage had something to do with displayed longevity, which makes no difference in this context.

The L-398 is the successor to my preferred meter, the L-28C. I am not in the habit of sweeping statements, but the Sekonics I have used from the 1960s and 1970s have all been perfectly serviceable.

When you say the “hundreds” of meters you tested were all “wildly inaccurate,” what exactly did your tests show? Were they consistently off by a stop? Or were they high for some readings, low for others? The first is no big deal, the second is a deal-breaker.

In the end, all a meter does is give a yardstick. The process of metering light for a photograph is inherently full of variables (angle of light, cloud cover, incident or reflective metering, use of a gray card, dynamic range of light and shadow in the frame, shadow content, etc) that renders absolute meter accuracy a pointless exercise for most. Some don’t even bother with a meter — they rely on their eyes to read a scene. The important thing is repeatability. Fetishizing absolute meter accuracy is a distraction for most people trying to make a photograph on film.

If the fetishists succeed in driving people away from old meters, that’s fine by me. I won’t have to pay stupid high prices for my Sekonics in the future.

I've had slightly bettter luck than that with selenium meters. Of 8 I have, 6 are still reading reasonably accurately. My worst is a Weston III that reads 1 stop high. Why high rather than low is puzzling.

Any old light meter that is over a decade old will most likely need to be adjusted for back into calibration regardless of the type of meter. To calibrate a light meter to a standard source includes more that just the reading accuracy, there drift adjust measurements that need to be returned as will as other controls. Just recalibrating a meter to a standard source will improve its performance.

I've

I've made multiple mentions of the Lume Cube lights and this is another, so hold on, please.

The Lume Cube Pro light has several features that should prove useful to calibrating a meter.

It's a Full Spectrum RGB LED unit, which also has light temperature control from a very warm 2700k to 7500k, it's variable light levels are set up in 100 steps, colour adjustments that are controllable by both an on/off Bluetooth ability from your phone, pad, etc., colour saturation intensity, etc.

These have a USB C connection, for battery charging and AC sourced, corded power, while in use.

I believe these are basic enough tools to bring adjustable meters in line within OEM parameters, but others must expand upon my supposition.

Cheers and GodSpeed,
Eli

To corroborate, I haven’t got one calibrated yet. I’m questioning the method as if maybe I have it all wrong (maybe they’re supposed to read low)

The dial IS loose and it cannot be fixed. I have dumped mine.

It sucks that we can’t have mercury batteries (even if we promise to be environmentally responsible with them) because they are a reference source of accuracy

For the old Gossen meters with 2 mercury cells PX 625, a voltage converting adapter with silver oxide cells is available from the manufacturer. This brings meters like Lunasix 3 back to life with modern batteries.


My Lunasix 3 is still accurate

My experience: Luna Pro still accurate after decades of use, this is also true of later model that uses 9v battery…but just too large for my tastes; Digisix is accurate but eats batterie, so often not working when needed; Sekonic selenium meter for incident reading still accurate. I have a drawer full of non working Weston, Pilot, Kodak, etc selenium meters.
Off topic, I have Pentax spot meter, as well as Gossen spot meter. The Gossen is way too large and complicated for easy use. Pentax very easy to use.
