oh my...kodak 400cn

[fbf]

Just developed my first roll of 400cn with conventional b&w processing. The result is decent but scanning is really killing me here. I remember someone here mentioned about the orange casting is somehow affecting the scanning speed. Unfortunately, that is TRUE... I scan in 48-24 bit color with 300 DPI and the file size is around 16-17mb. Single image takes about 8 mins...that's 2-3 times longer than regular b&w film scanning:bang:.

Is it because when you scan silver, you're only scanning in greyscale and therefore only scanning one channel instead of 3?

No, I scan everything in 48-24 bit color:angel:

If you're using ICE for dust removal, that doubles the scan time. I don't know why the orange cast would make a difference, except as the last poster said, maybe because color takes longer in general.

I never actually use the ICE because I handle my films very carefully and I can do a much better and quicker job in ps. I scan color slides regularly and the speed is acceptable and is definitely faster than scaning the 400cn.

Funny. Go away, troll.

The only reason I can think of to use 400cn, and it's a good one, is the convenience of minilabs and their 1hr process/scan/CD...minilab scans are "good enough" for online, not for letter sized prints or above...$6 process/CD...not bad for one hour from Walgreens (pharmacy).

Ice doesn't work if you process 400cn normally.

Ice doesn't significantly affect scan time with recent Nikons...V never takes longer than 1.5 minutes @ 4000ppi making 120mb file sizes from color.

Scan time with recent Nikons isn't affected by film type. The orange is irrelevant.

 

[angeloks]

Haha, that doesn't make sense to start with. Yes, an orange image takes a while to scan. Green is a bit faster and definitly purple is the fastest. The shortest the wave length, the better it is. OR NOT...

IMHO, orange images doesn't take more time to scan than blue or brown or yellow... And I wonder why you'd want to scan 400CN in color. You won't get any additionnal information on your final picture.

And JTK, the Digital ICE makes the scanning longer... But I think it's worth it and that's the reason why I'm using XP2 or 400CN.

Care to explain?

User is new, has asked a number of 'innocent' questions about processing C-41 chromogenic film (color process) in B&W chemistry. Anyone who has ever processed C-41 film in B&W chemistry is aware that it can be done, but with absolutely horrible results - it is a method reserved for last-ditch only, unless some freaky artistic effect is desired - film speed is effectively reduced from ISO 400 to around EI 25 if that. Of course it would be difficult to scan - you could scan your cat with less difficulty.

And the earlier 'innocent' question about whether he could process C-41 film and B&W film in the same tank with the same B&W chemistry at the same time - come on. Nobody knows that much about processing and is still that naive.

My opinion - he's having a great old time at everyone's expense who is attempting to puzzle out his so-called scanning problem.

XP2 in Ilfotec HC

XP2 in Ilfotec HC

To satisfy my own curiosity, and feeling that tmattock may have been a tad harsh, I loaded a 24 exposure roll of XP2 into a Yashica-FX (OK not a rangefinder, but wanted to play with 135 lens plus extension tubes), set the camera to f/4 and 1/50 sec - metering to iso 250 - and pointed it a potted plant and the dog.

Developed in Ilfotec HC for 14 minutes, agitating once per minute, very milky when it came out of fix, refixed another 5 minutes - still milky so just ran fingers down it and left it to dry.
Horrible brown streaks down the film during drying; resisted the temptation to wipe them, and they disappeared once dry. Left with a film with a light purplish tinge.
Scanned with Epson 4990 + vuescan - nothing amazing and some blown highlights, but quite usable.

I appreciate that XP2 doesn't have the orange mask of the Kodak chromogenic film, but I feel that with a little experimentation that this C-41 film at least could be used with conventional b&w developers and then scanned without much difficulty; it won't be my favourite combo, but then I'm still learning to focus!

 

[bmattock]

Hahaha! Well, there you go, I have to stand corrected! The only time I've ever tried to process C-41 (color) film in B&W chemistry, I got bupkis - an image, but totally non-scannable. Well done.

 

[Benjamin Marks]

I gotta say, I had the same reaction as Bill. In fact I gave the same advice to another user in another thread a couple of weeks ago. Ya learn something new every day.

I'm still at a loss as to why you would want to process BW400CN in b&w chemistry. It doesn't yield any remarkable results (like crossprocessing slides does, for example). You just end up with a b&w image. I use a lot of 400cn, but it's for the benefit of using a 1-hour photo lab.

Is there some artistic reason to process it in b&w chemistry?

The only reason I ever heard to process C-41 (of any sort) in B&W chemistry was to recover images from rolls of color print film so old that there was a fear they'd be destroyed (if they still existed at all) by commercial processing in C-41 chemistry. I've never heard of any 'artistic' reason to do it, and none at all to specifically do chromogenic B&W in traditional B&W chemistry.

My one and only experiment so fouled my D-76 that I dared not reuse it, and left me with a negative so thin I could see the outline of images, but could not scan anything at all. In fact, I thought I'd never get my reels clean again, either (I still used reels then, instead of the aprons I use now).

 

[Keith]

I thought he was refering to 400CN which isn't chromogenic ... it's just C41!

I've developed BW400CN (chromogenic) myself in Xtol and there was no real problem and I got very fair results!

 

[Keith]

Keith, is there any advantage to processing 400CN in b&w chemistry? I was just wondering what the point was of doing it?

I did it for the same reason Sir Edmond climbed Everest ... because it was there! 😛

 

[bmattock]

Some company - don't remember which now - used to sell respooled color movie film for 35mm that had a nasty black backing that would make a real mess. Perhaps you got hold of some of that. That was a long time ago. It was cheap, but sure not worth the effort.

Yeah, I remember that place in Seattle. Filmworks of Seattle, or something like that. No, this wasn't that. I just remember watching in horror as my D-76 came pouring back out of the tank looking like used engine oil sludge, complete with gooey stuff at the tail end. No way was that going back in my D-76 jug.

Of course, now I mostly use D-76 1:1, and hence, a one-shot. So I guess it would not matter now.

I have to admit I'm surprised by the quality of the results shown here. Like you, I do not know WHY someone would want to do it - when I shoot C-41, it is generally because I want quick results from a one-hour lab, and am too lazy to break out the chemistry set in the kitchen.

 

[MikeL]

Well, my first thought was that the long scanning time had nothing to do with the orange mask and everything to do with a dense neg. Keith, if I remember right, your negatives from b+w chemistry were very dense, but you still had some contrast to them. Didn't you have long scanning times?

 

[fbf]

To those of you who asked why, simply because I don't want to go to the local 1hour lab and I got the bw400cn for very cheap price so i don't mind process it myself to test it.
