Nice article. A couple of questions:

1) is the upshot that digital negatives produce visibly worse/different
results from conventional negatives?
2) the contrast of the digital prints seems higher and in particular the
shadow detail seems less. Is this the case when viewed "not on the web"?
Would a curves adjustment help?
3) That is to say, can one use photoshop techniques to improve upon the
conventional negative and thus overcome some of the inherent
difficulties with using a digitally reproduced negative?
