Yup, possible in theory although I don't know that it can be done with a 6x7 cm camera. 645 seems to be the prefered format.

It's a stupendous committment, financially and equipmentwise, but Really Serious landscape and studio photographers wring excellent results from mid format cameras.

Needless to say, we ain't talking ultralight, light or even midweight kit here.

You'd also want really good lenses to capture enough detail to warrant a $20 or $30k digital back.

The other path is continuing to shoot film and have the negatives or slides scanned.

Cheers,
