I revel in the idea of using the Wrong Camera for the Job, it's part of the joy of photography for me... So I'll take landscapes with a Kodak Pocket Instamatic and I'll go to Disneyland and take family snapshots with 4x5. It's a wonderful feeling to do less with more, or more with less. Just messing around with quality is so much fun.
I shot landscape with 35mm Tri-X for an entire year, just to prove to myself that I could make nice photographs with it. And I did (I think, anyway). They are different from what I get with the Hasselblad, but not less worthy in my opinion.
What using the 'wrong' camera for the job brings out is creativity and thinking about what we do, to pay attention to what's important. I have always thought that it's essential to bring back the mood and feel of a place, and while detail and resolution can be nice, it just isn't that important. Do I think that enlargements from 6x6 look nicer than those from 35mm? No. I think they look different. The grain of 35mm brings something to the photographs in the same way the lack of grain can bring something, and sometimes the lack of detail lends a beautiful quality too.
It's much nicer to focus on the positive aspects of a photographic print than it is to focus on the negative aspects, but it's much more difficult to do. To pay attention to what we actually DO get, irrespective of what camera was used, should be our prime concern, not whining about wishing we had a camera that makes a bigger negative. Just get on with it and make beautiful prints, and have a good time doing so!
For those who are concerned with quality from 35mm, try TMax 100 some time, and process in Kodak Xtol for a sharp but extremely fine grain negative, and then print it big. When I do 16x20 prints from such negatives, (cropped to fit an aspect ratio of about 2:3), I am always flabbergasted and can't really understand what it is that folks have against it. Smooth beautiful transitions of tone, sharp detail, and the little bit of grain that's there lends a gorgeous texture, kind of like how FP4+ would from 6x7 negs. Obviously it isn't as smooth as 6x7 or 4x5, but it is really really good.
Then if you want more texture, just pop a roll of TMax 400 in and prepare to be amazed again, for it is a mighty fine film too. And then you can go bonkers and shoot Delta 3200. Use Rodinal for good measure, and when you enlarge big you will be very surprised at the detail you can get behind all that gorgeous grain. It's a very wide spectrum of results that are available from that tiny little negative.
