I have an opportunity to get a Hasselblad 500 from a pro (duh) who used it to shoot weddings for decades. What would a fair price be, and can I still get film & develop it? Works great, has the 120mm back and zeiss lens in excellent shape.
If you have never used a medium format camera be ready for some pleasant surprises. You should have no issues finding film and there are plenty available at professional camera stores.
Medium format, by offering a larger negative will give you sharper pictures full of details, especially big enlargements.
Try to stick to low ISO film if you are going to be enlarging to sizes like 20x24, a piece of cake with these cameras. That will keep an acceptable grain in your prints.
I like Tri-X and I did lots of testing to find out, with my Pentax gear, the appropriate ISO to expose it and the best development time for the highlights. I can tell you right now that I ended up with a significant departure from the times given by the manufacturers of film and development. I used Rodinal with T-Max 100 at the time, but you can use HC-110 Sol. B with Tri-X for beautiful negatives, like old Ansel Adams used to do.
For the best of both worlds you should scan some of the negatives. It will allow you to make corrections without being in the darkroom and those corrections you will not be able to duplicate them in the darkroom anyway.
Good luck and enjoy medium format photography.
