I recently finished a 20x24 wet plate collodion camera for a customer. Instead of loading this server with images, here is a link to the page on my site,
Wow, those people next to it must be awfully short.....a camera couldn't possibly be that big... I will have to say, though, that is the first "tripod" I've seen with storage! Amazing. I'd love to see Rob coat a plate that big!
Rob, I don't know. Yes I reckon I could and get with S&S about a filmholder. A film version could possibly be made lighter as the frame doesn't have to support a huge glass plate.
Andrew, all the cameras that I make are for wet plate collodion, so they are DIY plates, either metal or glass.
