Excuse me while I think out loud here:

I know the shutter will be held completely wide open for the Contact Time I've set minus ~.0194 seconds. That .0194 seconds is composed of the relay's coil...

Yep, The MultiMAX is pretty much acting like a fancy 555. I remember having a lot of fun with them in my old electronics classes. You could probably throw a photoresistor in there and make a metering...

Looks like you're right:

I used the multimaxes lag time measurement to measure the time between when it triggered and when it received a sync pulse from...

I put together an image with comments explaining how everything works, mostly:

I'm sure the mechanical aspects reduce the consistency to a...

Looks like I created quite the ruckus...

I have no connection to the seller on ebay (anyone have a link?). It agree it's a strange coincidence that they all disappeared from the shed the same day...

I blame a one-handed iPhone :)

Hi everybody,

I haven't been active around here for a while, but I thought I'd share an interesting discovery I made the other day.

Surplus Shed has a bunch of these electronic shutters right...

Sorry for the cell phone snap, but I just found a very large lens at the antique shop. Looks to be about a 350mm f/4. Two elements and no aperture. Here it is held on my Omega 45E with some mat...

Thanks for all the helpful info everyone. Turns out I'm going to need the shutter this friday... so it looks like it'll be either the tape method, or a rubber band for now.

Thanks again,

Hi Everyone,

I've looked around online and searched the forum already, and I can't seem to find a recent source for shutter parts. I have a copal 0.0 with stripped cable release threads, and the...

After getting lost twice on the way, and spending all day in a dilapidated house in 3 degree weather, I got this one portrait.

I finally got a chance to shoot with the lens. Attached is a scan of an 11x14 print I made. The subject is my gigantic aloe vera plant. As planned, I took this by firing my strobes while I had the...

I did some quick shutter speed tests this morning. 25 is about 1/30th, 50 is spot on 1/50th, and 100 is around 1/60th. Not bad at all.

Hi Glen,

I've drawn on the image to help illustrate where the frame counter is. It advances from 1-12 every time I trip the shutter. It's hard to see in the picture because of the way I lit it,...

Got to play around with the lens a little more tonight. I checked it with a ruler and the aperture to ground glass distance at infinity is pretty darn close to 175mm. Also checked for any writing on...

Wow awesome. Exactly what I was looking for. Thank you. The paint around the barrel is pretty worn, but I'll check that out and do some shutter speed tests tonight. I've already looked up the stop...

Hi Everyone,

I picked up an interesting old lens the other day and was hoping for some help identifying it. The ball bearing shutter it's in is stamped with Kodak, but other than that, it doesn't...

Hi Bill,

From what I can gather, that 273 adapter is going backwards. Looks to be for turning a camera tripod into a surveying one. I use a surveying tripod for all my LF stuff. I started off with...

Here's the Omega 45E with my new 60mm f/1.8 in the "studio."

I had the same objective and took a slightly different approach. I found a surveying tripod on an auction site for about $100 shipped. An afternoon at the hardware store converted it to work...

And finally a real print, my first enlargement from a 4x5 negative actually. Fortezo toned lightly in sepia followed by a strong dose of selenium. The darn thing won't quite fit in my scanner though....

I had a great opportunity to exercise my camera muscles the other day. I set up my strobes and did some portraits of my roommate. He had the idea to do a "surprise portrait," which involved me...

This is my first LF negative.

My Omega 45E on the new surveying tripod. It gets real big. 25 pounds of camera gear isn't very fun to haul around though.

Hi Everyone,

I was cleaning out the darkroom at my local college when I came across an unopened box of type 55, stamped with a date of 1988. Just a while back I picked up my first 4x5 camera and...

I finally did it. The other day I bought a 4x5. It should be here the beginning of next week. I've been wanting to get into large format for a while. Been perusing the local craigslist, checking...
