I have been getting to know Packard shutters a bit and today I tested what I have with Shutter Speed App. https://itunes.apple.com/us/app/shut...560154244?mt=8
I used the same OE new bulb and rubber hose for all except #3 which has DIY RC servo control.
1. 2" Packard #6 1/6 to 1/60th second, depending on how hard and fast I squeezed the bulb. I am not consistent.
2. 3-1/4" Packard #5 1/2 second. About as fast as I can make a 'time' model run. Slower is easy once you learn the trick.
3. 3-1/2" #5 Packard electric modded to RC servo 1/2 second, consistently, and can loop, so it fires every 1/2 second. and it has adjustable flash sync. Ghost pics coming up.
4. 4-1/2" #6 Packard double pumper 1/10th second and slower, hard for my crappy hand to deliver.
For those that don't know about Packard shutters and types, such as #5 and #6. http://www.packardshutter.com/
I have learned they need to be used vertically and with the correct side up, which is not intuitive as my reasoning had me trying them upside down. Pulling the biggest one out of my Studio Ansco made me realize which way is up!
My conclusion is, the bigger they are, the slower they run and it's good to have the 'pin' model #6.
Mine are as old as the hills, new ones may perform faster, but these things have almost no friction points and seem to last forever.
Anybody have any tricks or advice?
I may try compressed air supply to see what I can get. Maybe broken shutters!
