A probably impossible question to answer here but..
For my two new projects I am looking at shooting 8x10 instead of 4x5 simply for the extra IQ for large prints upto 150 cm wide. (lambda prints from drum scans of colour film with longish exposures up to 30 seconds.)
The kit will be a one lens set up..camera + 240mm lens + say three darkslides at most on shoot.
Fair enough you say, but some of these shoots will involve walks up and down steep mountain sides and across slushy snow for up to an hour and a half or so. (Then again some will be just five minutes from the car).
Am I crazy to trek to these kind of shot locations with a heavy 8x10 set up and will I see a big difference in the print quality at the sizes I mention?
I have shot 4x5 for years and love it, and am generally happy with the print quality I get but know that 8x10 will give me even more.
So, crazy...just do it...not worth it...?
