So I'm wondering whether its OK to scan the other side of colour negatives or are you more likely to get more grain and other nasties by doing so in your scans or not??????
Dunno if its my imagination but i'm getting less of my arch enemy Newton Rings by scanning the other side!!!!!!! the emulsion side i believe you call it????

Also used and scanned Kodak Portra 400NC for the first time...rated at 320 film speed.....my conclusion: SUPERB FILM TO SHOOT WITH AND SCAN.....looks like a 100asa film to me.....

I'm into the soft, pastel palette at the moment....my film of choice being 160NC as you know

Following the advice of people here and on the Hi-end scanner group in yahoo I've battled with using a colour negative profile (scanning as a negative NOT as a positive) and It's going well for me......

I am struggling to get the optimum results as sharpness i need with my scanner, the color i can get is fine from my scanner with either negative or positive[slide], but i am now experimenting to get the best sharpness i can get out of my scanner.

.........the main problem I'm having is Newton rings as I always go on about.....so started scanning my colour negatives back to front, ie the images are scanned the other way round....what I'm asking is whether it affects the grain size or anything else you get.....

I think other people scan the emulsion side too if im not mistaken and would like to hear from them too......

Sperera,

Have you tried scanning the same negative, or strip of negatives emulsion side down, and then emulsion side up. If so, I would be interested in the results, and probably more importantly, you might or might not see a difference. And of course, you would want to be sure that the image wasn't reversed, which is what would happen with my film scanner. That's easy enough to correct - if the results warrant it.

of course the good question is already asked (as I don't recall what your scanner is either

scanning with emulsion towards the sensor is my personal preference it won't make any difference to grain (which I would argue is mostly not visible and what we think of as grain is often something else)

before I go into saying anything about newton rings I'll wait to hear about what scanner / holders your using

Hey Pellicle, I'm scanning with a ScanMate 5000 and dry mounting (I have all the KAMI stuff but i havent got a mounting station and mounting on a cylinder with liquid that acts like water is a nightmare for me - I have to find a technique for myself yet....I mounted one properly once though and it was superb I must admit).

Software: I use ColorQuartet software running on Mac OS 9 off SCSI connection with a dongle key (physical)

I'm scanning as a 16-bit RGB TIFF colour negative.....NOT scanning in positive and inverting..........I am using a profile that's giving me good results albeit with a tendency to overload on the green a bit which is easily corrected in Photoshop in my experience. I can, however, edit the profile im using and tone down the green on its curves but I havent done it yet.....

I'll post some scans....give me a few mins......

Hi

ahh ... that's right ... now I remember

about the newtwon rings

Andrew Rodney is no dope, so I'd take his word with a reasonable reputation.

I would think that if you're through looking the base at the emulsion to get the image it would be less ideal.

Grain seems to be on the scratch coating however... so "grain" may come from there too. as per this post
