My initial jump into large format came after months of contemplating the idea. Try as I might, I couldn't get myself to pull the trigger on a $500+ folding camera like a Wista or Shenhao, and wasn't about to buy a more affordable studio camera to lug around in my backpack. The camera I finally settled on was a badly used Graflex Crown Graphic from ebay. The camera, with the lens and 3 film holders, cost $150, including the shipping. Is it ideal for landscape photography? Not really. The movements are extremely limited, and it won't fold up with my Fujinon 90mm mounted. Still, it was really really cheap, and it's hard to argue with that. What DSLR can you get for 200 bucks?
The lens that came on the camera was really a piece of junk. It's a Graflex Optar 135 (wide normal) that would, in great condition, probably be worth less than $100. It had no coverage for movements to speak of, was scratched pretty badly, and stuck for several seconds on any exposure longer than a quarter second.
As soon as I was able, I picked up a Fujinon 90mm f8 on KEH for around $300. This lens, which is roughly a 30mm or so on 35mm or digital, is a little bit more difficult to focus on the ground glass, but provides superior images. Plus, it's pretty.
So far, I've shot exclusively Ektar 100 and Black and White. I have a box of Kodak Portra 160 on the way from Amazon, so I'll have a broader range of experience with it soon.
When I get my negatives back, I run them through an Epson v700 flatbed scanner. If I ever take any really dynamic shots, I'll certainly get them drum scanned professionally.
Just for fun, here's a negative on my ghetto light table (a Kindle Fire running a flashlight app.)
And here's the same image after scanning.
So there you have it. A fully functional large format kit for about $400. That's what you'd pay for a Canon t3. Grab a tripod and cable release and you're ready to roll. My next move is to pick up an old Pentax Digital Spotmeter on KEH, then to upgrade to a wooden folding camera, and possibly buy a portrait lens. (Whatever money I make with the digital camera gets dumped into the large format.)
If you shoot large format, what's your setup? Where should I go from here?
