Ugh, film... yeah the tolerances aren't as big a deal with the longer lenses, also film just doesn't have the same sharpness, so the problems aren't so obvious.
But man, whether you shoot chrome or neg, nailing color balance is a pain and even then you get crossover... green shadows, magenta hilights not to mention that chromes have half the tonal range of a digi-back, requiring more lighting to attain shadow detail and forget about HDR or trying to align multiple exposures... aligning scans can be a nightmare.
I like color neg for my personal work, but for commercial work where the color palette has to be matched precisely?
The only thing I miss about 4x5 film is having a big ol' groundglass to look at.... but then my laptop screen is even bigger!
Digital... I dig it all
