Well, you know Devin, composing reversed left-to-right is what waist-level SLR and waist-level TLR shooting is alllll about. Adding upside down to the laterally reversed image seen with a view camera is something a person gets used to. One thing that using a view camera DOES do though is it trains you to THINK about composing, and it forces you to sort of mentally map-out the things that you include within the area of your frame. Also, the view,even under the dark cloth, is somewhat DIM, and you sort of have to move your head side to side and up and down in order to read the entire scene...the view is actually dim, and not "of the whole,entire scene". So set-up, and placement, and ticking things off mentally, element by element, is the way composing is done. Yeah, it's all up[side down, and laterally reversed, so you have to use your training and brain to sort of "evaluate" the composition, and what is in the frame.
Some people are of the mind that viewing things upside down actually IMPROVES composition, by forcing the photographer to learn to perform what amounts to a sort of mental gymnastics routine when making each and every new picture. With the time, effort, and costs associated with each and every sheet of 4x5 film, and the rigorous technical demands of shooting larger format film, photography and composition are "different" than when firing off cheap, easy, fast shots of 35mm-style film or digital. It's slower, more-deliberate, and,well "different".
