Ok, it seems my initial research is going to be about figuring out how to use 4x5 film.
So... to loop back to the beginning: is there 4x5 Polaroid or other "instant" film available to check the shot?
Oh, and... what the heck am I looking at when composing the shot? Is it a Viewfinder? Does it have frame lines? What is Ground Glass? God knows it sounds lovely...
I will now start parsing a lot of your responses... I have been Googling my hands sore... (I know, there's a "blue" joke in there somewhere...)
Right, Italy - France Euro Cup game starts is 40 minutes. Let's hope they draw, then they both drop out.
