The Jim Galli shutter for barrel lenses. Drum Roll Please:

[jimgalli]

Drum roll please. The world has been waiting for me to invent this. Here it is and it's even easier and cheaper than Andre's and Denis's shutters.



Simple! Affordable! It's all in the wrist action. I can get 1/125 second with my shutter. Used it today on the Eastman 11X14 with the Plastigmat lens.

Now in case you want to fuss that my slit that passes in front of the lens is V shaped and doesn't distribute equal amounts of light over the film surface, I'll remind you that 90+ % of all the film that's been exposed in the last 100 years was done just that way. That's how movie camera shutters work.

Detailed instructions:

1) Firmly grip 2 5X7 film holder slides with about a 20 degree angle left open between them.

2) Place the lower one over the lens. It's OK to touch the lens at this point. Pull the film darkslide.

3) Move the "shutter" just in front of the lens so it doesn't touch.

4) Pass the slit in front of the lens and stop when the upper holder is covering the lens. It's OK to touch the lens at this point too.

5) Replace the dark slide.

6) Exposure control is by how 'fast' you flick your wrist. I was after 1/4 second and moved fairly slowly. In fact I went down once and up once. 2 1/8th second exposures if you will.

7) Need 1/250th? 1/500th? Simply close down the slit to 10 degrees or 5 degrees. I'm still working on the flash sync

Taking orders for the Jim Galli shutter. Write your address on a $50 bill and mail it to me. I'll get your shutter mailed right back to you.

Jim,

Heck of a deal. How does the bulb actuate it? How many sheckles are you charging for this?


What in the heck is that white stuff on the ground?

The bulb is for sissies. It goes to a balky old packard. Charge? Why it's free as long as you write your address on the $50 bill. What white stuff?

[James M. Bleifus]

Jim, it looks like you're attached to the shutter. Is this your elaborate scheme to get us to fly you around the country?

Cheers, James

Hey, if you patent this, you can threaten to sue anyone who buys a 5x7" filmholder or darkslide on eBay and corner the market on 5x7" filmholders.

[Dave Wooten]

It looks like you have abple rise and fall on that front lens, couldn't you simply mount your shutter blades just in front of the lens and just simply raise or lower your lense past the open slit. you could even have it spring activated

A wise man once told me something to this effect:

"Why are you going through all this trouble when Packards are so cheap? But you're having fun, so sally forth"

Looks like my forth-sallying has infected you; my condolences.

Pretty cool deal, though. I'll have to reverse engineer this and upgrade my own somehow

I'm sending a $75 bill (you know, the one with president Goldwater on it). Please send the patented Galli-Shutter with flash sync.

I reckon you could get $100 bills if you merely rename it to the 'Jim Galli Patented Petzval Shutter'... (or $150 bills from Matt with a President Spiro Agnew mug on them)
