i think the newest/best is the new 39mp backs. Pretty impressive but if i had that money, i'd be using it for something else... $40,000 is a lot!

here's my argument.
Looking at big slides on a light box is just sooooo sweet!

And I lot quicker to edit through the shots! Don't get me wrong, I love digital, but I still love film.

I'm stuck in a love triangle...

Or I wipe off the lens, leave the caps off and let it dry out. Try that with a digital camera.


I know it's not particularly relevant or helpful, but there are plenty of stories of the (digital) camera getting destroyed and the card still being readable, whereas film would have been rendered useless.


Very extreme measure will destory both, I'm talking about the everyday mishap occuring.

Wouldn't any water ingress damage the film and render exposed frames unusable? (serious question, I've never used film to any great extent).

Also, if the camera got dropped and either cracked the casing or popped open the door, I imagine that the exposed film inside would become exposed again by the stray light, whereas the memory card in the digital camera is not particularly sensitive to light.

Still way off the original topic, I know. Sorry.

With film there are other mishaps that can happen too. I remember taking a dozen rolls of film into a highly recomended pro lab for a school project and having them give me back destroyed transparencies. They gave me a free roll of film for each.

It's easier to back up a digital file than it is to back up a negative.

It's like records and CDs - the record might give you a better sound the first few times but eventually it'll turn to crap. Sure you can make a CD of that first recording but it'll still be a CD in the end, so why have the middle man?

How good is the weather sealing is part of the question - I've heard tales of fully immersed 1DII's with a similarly sealed lens not having any problems at all (after creek crossing slips and the like)

What is your workflow for printing 40x50? Do you simply upres the image via PS? If so what resolution do you use? 300dpi? Doesn't that result in a huge very difficult to manage file? Do you have to have tons of Computer memory to do so?

I have a 6mp Nikon D100 and would be very curious to know how I could produce high quality prints at that size. Any thoughts on where to send the file for printing for those of us that don't have large printers?

Thanks!

If film gets wet, you keep it wet all the way to the lab.

Yes if the door pops open, your usually screwed unless you can cover it quickly of throw yourself over like a hand grenade. ;o)

This definitely sounds better. Would you feel confident enough to keep shooting with it after that happened?

I scan it in @ 4000 dpi resulting in a 298 MB file. That works out to 47.25 x 55 inches @ 200 DPI. I don't upres in photoshop. I use a 6 year old dual 500 g4 mac with 1.5 gig of ram ( yes I know I need to upgrade).

Just curious, but how does it return better results printing scanned film digitally instead of just enlarging it in the dark room?

And do you print your own photos or send them to a lab?

Ever priced out really huge "conventional" prints? Astounding. And you have fading problems with them. And you introduce a whole new optical system (the enlarger) into the equation. At very large print sizes, if the enlarger is not perfectly aligned you get serious sharpness falloff.

Add to this the fact that color optimization of the finished print is much easier in a digital workflow, not to mention fine-tuning sharpness to print size, and didgital is the way to go.

Just like the advantages to digital printing of small digital files. The pro rips allow for more detail for larger prints than traditional printing. My 6x7 scanned prints are close to 4x5 enlarger prints.

I always have a lab print my stuff. Who can afford a $50,000+ printer. :D I always print on either a lamda or a lightjet printer. Very rarely an inkjet.

I get a view camera for the semester, have to shoot mostly b/w ... but i ordered some velvia for it too. stuff is expensive. 20 sheets of chrome, I feel compelled to put them to good use, now I just have to find a good landscape in central IL and wake up at 4 am.

never shot large before, stoked.

Also just picked up 18 rolls of 6x7 chrome from mexico, ill post some scans within the next few weeks!

Agreeing with everything else you said but this, not because it isn't true. It is. But the point is moot. The scanner is also an optical system and it is also lossy. The only way to eliminate that generation is to shoot digital.
