Maybe going to LF in itself isn't moronic, but everything certainly gets exponentially expensive, especially the film the larger it gets. LF just make it even worse when you realise you've blown $20 on a single frame that you ruined from your own stupidity...
I find the I have similar issues when using my Hasselblad Arcbody. There are so many things to remember to do and on days when my mind isn't as engaged as it could be I am asking myself, is darkslide out, did i close shutter before I removed DS, what back have I got on, have I allowed for the centre filter in my exposure calculation, tilt/shift, lens shade adjusted, those moving boats have I got enough shutter speed and then the moment is gone. Is all worth when I get it right and 12 shots a roll is a little easier than with 617.
LF and the ArcBody do not have the interlocks that we have come to depend on. Without the interlocks to protect us, mistakes abound.
I just took the plunge into LF this year, and with all the disastrous mistakes I made with medium format while shooting in Chicago last week, I seriously wonder if I'll ever get anything good when the 4x5 finally leaves the house.
I've been shooting view cameras for over thirty years now, and I still sometimes make stupid mistakes. Doesn't matter. One good shot with an
8x10 is worth more to me than 500 with a small camera. You can only print so many images anyway.
