The bottom line in getting excellent results in photography has always been Converge and Working it. And it was easier to do that with 36 on a roll than it was with 12. Or with sheet film. Much more of a chance of capturing that magic moment and magic camera angle. .. than standing there going "click" and walking away. I have never been more excited about my work. And the fact of getting 360 or 3600 or more on a roll has done nothing but positive things for my work. On internet chat groups you'll read all about "overshooting" Trust me that concept did not exist before 10 years ago. Its a product of internet photography chat groups. A photographer comes back to their studio with their take and looks at it all and goes "damn! I wish I'd done a few more of those I may have not quite gotten it and damn! I wish I'd done a few more of those!" Never "damn I took too many of those!" that's an occurrence which just doesn't happen.
