DEAR RICH, I have a very old cherry wood Kodak 5X7 with a portrait lens in a Packard shutter. The lens is perfect for portraits in that it is very sharp when closed up but nice and soft when opened up due to purposefully uncorrected aberrations. The Packard shutter is great and, with some experience, can go from (as Richard said) around 1/25 sec to as long as you like. The trick is how you use the bulb. If you want short exposures you slowly, partially squeeze the bulb without putting your thumb over the air hole. When you want to make the fast exposure, while keeping your thumb over the air hole, quickly squeeze and release the bulb. This causes the shutter to open quickly and, because the bulb was partially compressed, it "sucks" the shutter closed again as quickly as it can work. For time exposures you do not partially compress the bulb.just put your thumb over the air hole, squeeze the bulb and hold it as long as you need the shutter open and release bulb to close it. For VERY long exposures, thumb over air hole, squeeze the bulb, remove thumb from air hole and slowly allow bulb to re-inflate. When it is time to close the shutter, without your thumb over the air hole, gently squeeze the bulb, then put your thumb over air hole and allow the bulb to re-inflate, once again, sucking the shutter closed. This has worked for me for decades. Enjoy the wonderful feeling of the 19th century in your hands! CHEERS!

Did you get the sync'ed version to use with strobes. They work great, only problem I have is the process lens was really too sharp for portraiture.

I have a 14" f/9 Apo-Ronar barrel lens mounted on a 6" board for an 8x10 Kodak 2D. A test shot of some book titles on the shelf looks good and the aim is to use this lens for portraits. So after months of searching eBay for a Packard shutter, google search found www.packardshutter.com. I called them up, talked for 20 minutes to the owner, Reno, who carefully explained what would fit. I'm getting one and can hardly wait to squeeze that rubber bulb! These shutters were generally used before my time and would like to hear other's experiences with these classic shutter.
