Shooting Outdoors With a Barrel Lens.

[Smitty]

How do you control exposure with a barrel lens especially if you want to use a lens wide open? Late in the day?

Hopefully by buying a shutter for the lens and installing it! Alas, one of my favorite lenses is a barrel tessar that I haven't bought a shutter for yet, so I use relatively slow film 8x10 like FP4 or ACROS, along with either a deep red 29 filter or deep blue 47, depending on what I'm trying to do with shadows. That typically
slows me down to 6 or 8 seconds, and allows the lenscap method of exposure. You obviously want a cap that can be removed quite easily but is also light tight.
I was shocked the first time I did this, because the negative came out completely sharp. A very stable camera and tripod too. Now that I've gotten better at it,
I pull some tricks like stationing the camera behind a tree as a windbreak, but shooting mixed scenes of wind-blown grass combined with immobile rocks etc.
The blue filter opens up the shadows and sky much like old 19th C blue-sensitive films. One more toy in the toolbox.

Thanks,
Just got off the phone with Grimes, told me that the lens is too big for a shutter. They can make a flange and I will probably need to use a Packard shutter.

I use something called a focal plane shutter and the f/stop of my choosing.

You missed a Thornton Pickard or similar roller blind shutter, I have one or two (well maybe 50+)

There's two types, the original which was design to be fitted to the front of a barrel lens and then the Between lens type which is screwed to the lens board and the lens fitted to a removable front panel allowing the use of more than one lens. They came in a variety of sizes but the larger diameter shutters are a lot rarer. B&J were the US importer, Kodak Ltd used to sell them in their Professional stores in the UK. They were made up until the very late 1950's long after the TP Ltd company had ceased trading by a workshop which continued trading as Thornton Pickard.

That is the Galli shutter link.

I use a front mounted Packard shutter, or for the really large lenses, a Galli shutter. Look up Jim Galli on here or the web in general.

I use very slow film, Efke 25 with my Petzvals, along with up to 8 stops of ND filter held in front of the lens (and a black glove on my had as "shutter".) I have a Packard shutter but it's something like 1/25s--still pretty "fast" in daylight. My favorite solution is to simply shoot at night.
