Hello from Baltimore!
I just found this place while researching some packfilm stuff. Of my instant cameras, I use an Automatic 250 Land Camera, an SX-70 Alpha 1, and an SX-70 Sonar. I've also got a Keystone Everflash on the way that uses packfilm. I also shoot a lot of 35mm film. You can see some stuff here.
Thanks for having me. I'll be reading and learning for quite a while here...
