Photo Forum / General Photo Topics / General Topics / May 2008scanning negatives on commercial copier
I have access to commercial colour copier/scanner at work - but I notice negative scanners have special clips that hold about 6 negatives at a time is there anything to stop me just putting a strip of colour negatives directly onto the glass & setting it to transparency? how are negatives normal inverted - by the scanner or by software - is there any software that can invert negatives? > I have access to commercial colour copier/scanner at work - but I notice > negative scanners have special clips that hold about 6 negatives at a time [quoted text clipped - 4 lines] > how are negatives normal inverted - by the scanner or by software - is > there any software that can invert negatives? A. No. The scanner must have a light source _behind_ the slide or negative; the normal reflected light in scanners won't work. B. The software furnished with scanners will take care of that. Also, most photo editing programs will flip BW, but I don't know about color. Incidentally, color negatives underwent a huge change in, as I recall, in the 1970s; the background color was lightened considerably. I haven't done any color neg scanning myself because the old color stuff that I scanned was in the form of slides.

Yeah, I read in a book (since I was born in 1973) that in that era, you could get a negative film without an orange mask, and there after it came *always* with an orange mask.

I think that Allen was referring to the transition from C-22 to C-41 chemistry compatible emulsions, rather than the introduction of the orange mask itself, which (without showing my age too much) was more than a decade earlier. ;-) C-22 films, eg. Kodacolor & Kodacolor-X, had a much deeper orange mask than C-41 emulsions such as Kodacolor-II and its many derivatives.

I used very little color neg film in C-22 days, as the quality of reasonably priced commercial prints was pretty low. Also, although I processed many, many rolls of slide film I never got into color neg processing, lacking a darkroom (very hard to get an enlarger into a changing bag). I had a darkroom in my parents' house many years ago (I'm 79, so I do mean many), but it went away when I went away. I used rental darkrooms for BW printing with very good success, but no color.

My first ventures into colour processing were using the C-22 process and still preferred it for a long while after C-41 came along. The lower process temperature and longer times were much more amateur friendly and, although it still had to be maintained very precisely it was easier to do around 20C compared to 40C. In those terms it was a similar change as going from E-4 to E-6. SignatureKennedy Yes, Socrates himself is particularly missed; A lovely little thinker, but a bugger when he's pissed.

I had a colour darkroom, in Kozani ( a town in the Northwest Macedonia;not the country, the greek province) and I did slides and colour prints, also Ilfochromes. I had gotten some Tetenal chemicals, that you could do the RA-4 process at room temperature, also 20 C. Then, the local shop (in Athens) shut down and I came back to Iraklion, so I started using the Kodak RA-4 Hobby Pak ( and the E-6 Hobby Pak, goes without saying). My photos, except half a dozen or so, were nothing to write home about.... My digital era photos, are much better, and produced with much less hassle.....

Tetenal also did their version of EP-2 chemistry that worked around 20C, long before RA-4 high speed processing appeared, and in the UK there was "Photocolor-II" universal C-41 and Ektaprint chemistry that worked at 18-45C by controlling process time. I never found any of these third party chemistries to be as satisfactory as Kodak's own home process kits, although I eventually standardised on Fuji paper. Yes, digital is much simpler and the results are certainly superior - but after 50 years of progress you would expect them to be! ;-) SignatureKennedy Yes, Socrates himself is particularly missed; A lovely little thinker, but a bugger when he's pissed.

Yeah, I remember they had EP-2 chemicals and papers, and also R-3 (IIRC), the one that lets you make a print directly from a slide. I liked the tetenal cheicals very much. I used Tetenal paper, and then Kodak. When I went digital, a few years ago, I gave all of it away, to my sister's friend, paper and all. I got the Ilfochrome kit from a shop in Munich, with detailed instructions in german, good for practising them:-) > Yes, digital is much simpler and the results are certainly superior - but > after 50 years of progress you would expect them to be! ;-) Good, that scientists do so much to improve our life:-) Mobile phones, fast computers, clean cars and digital photography.

My negative scanner's software has inversion software are part of the driver. It also has profiles for different types of film. But if you don't have such software, most popular photo editing software has an invert function. |
