Ideas for new shutters 40 years from now when ours are all dead

[MAubrey]

So it runs at 1/50th or less.

Small Packards can do that or close.

I suggest we all stock up on small Packards as the Sinar shutter is already rare and who fixes them, Bernice? I have a perfectly working Sinar I will never take into field dust and grit.

I have plenty of 'Barrel lenses' which are actually Cobal shutters with lens in disguise which are shuttered with a Packard.

A Packard is easily cleaned.

There's someone on the auction site who advertises fixing Sinars.

And thankfully, packards are still being made new.

Those of us still around will be 3dprinting the lensboard+shutter enclosure and lens threads as one unit. Mechanical parts will be surplus carbon fiber or graphene shutter and aperture blades, and they'll be operated by actuators and timing sensors from vintage drone and robotics systems. Someone will 3d print a packard and think they've come across something completely steampunk retro, but not realize packard shutter will probably be still sold. Come to think of it, perhaps we should be looking at new materials for packard shutters; they could probably be quicker with lighter blade materials operated by a shorter throw tube that does not require as much air and travel.

If I remember correctly, Kerr cells required high pulsed voltage to operate, and a bit big and clunky...

I have an LCD shutter somewhere that changes its cross polarization when voltages are applied, but as mentioned, they are not 100% light proof and a fairly heavy ND factor... (I found it at surplus and wanted to build a silent 35mm camera for theatre photo jobs I was doing at the time, but the ND factor would have made available light shooting difficult, its large, and no instructions came with it so never messed with it...

A small format Copal type FP shutter could probably be adapted fairly easily...

Best invention ever! I bet it was patented by Canon.

Back on topic: in 40 years time there will be no more film available, so nobody will care about defective shutters anyways. If you want to shoot analogue, the only option you'll have is to make your own sensitised emulsion: collodion. And collodion is so slow that you can get away with lens caps instead of shutters. Shutter problem solved!

Not when you want to shoot wide open on a bright day.

ND filters will fix that.

Thanks!
I got quite a laugh out of the notion of outliving my shutters in 40 years.
ROFLMAO!

I said it might happen.

I have already resurrected 3 times, meaning returned to the living.

Worse things have happened...

Once owned a Sinar Digital shutter, fastest shutter speed is 1/500 second verified by storage Oscilloscope test. During all the years of owning and using that Sinar Digital shutter 1/500 second was never used... ever. Fastest shutter speed used was 1/60 second and that was on very seldom occasions. More used were the slow speeds of 1/2 second or more. If using larger lens apertures were needed, adding a ND filter works good.

BTW, original Green Sinar has 1/32 second setting ( f22 in Bright Sun = 1/32 sec with ISO 100 film, their take on Sunny 16 ?) on the far left hand corner before "B" and the other shutter speeds.

Use an ND outside, Alex!

Maybe a silly question, but do we need it to be leaf shutters? Is there a problem if we could make something like a focal plane shutter used in slr cameras but with a housing compatible with the Copal/Compur style shutters? On a french forum someone actually made a complete camera including shutter with rolling curtains. He made it from scratch with noting more than hand tools and a lathe. So hand making shutters isn't impossible.
