Hello people,
I have this question:
Should a white balanced vuescan scan with film setting generic of Ilford XP2
(a monochromatic film) look black and white?
I ask this because the first time I used this film I got sepia toned prints
back from the lab. The other times they were greenish or

At risk of starting World War 3, what is the resolution of Chemical

The National Geographic magazine used to ask for any photos to be
submitted using Kodachrome Film, so let's say Kodachrome 64 as a good

'a number'.

A very brief and simple answer to your inquiry to the initial question is
yes they should look black and white. The reasons the prints from the
processor typically do not come out black and white is because the prints
usually are printed on a dye based color photographic paper base which

Chris,
It does seem to be a hot topic but I would like to share my experience and
observations on this subject. I have been involved in a number of studies
regarding resolution as it applies to process cameras, still, motion
picture, and television (including HDTV).
Film resolution is only one

That so-called resizing is nothing of the kind!
All it does is change the dpi figure in the file, the picture content is
completely unchanged.

That's erroneous to say they are 'utterly meaningless'. They CLEARLY are

I believe that XP2 film can be processed C-41 like color neg and is often
printed on color paper. The green or brown or blue print color is due to
the processor operator's sense of neutral color balance. If you scan them
as grey scale you should get a neutral bw image. If you scan as rgb
Am I being naive here or does the settings for colour film take into
account, neutralizing the orange mask on the film base, and the settings for

items accounts for the orange mask used by that brand of film or film type

Which of the next 2 procedures results in more loss of picture quality?
1. Downsize an image (w.r.t. number of pixels) using bicubic resampling,
then go from 16 bit / pixel to 8 bit / pixel.

HI Jerry,
I'm sorry that I not going ton try to answer you earlier question
concerning which procedure creates less loss (downsampling, then
lowering bit depth or the other way around) because it will probably
invoke too much back and forth conjecture based upon theoretical
grounds, when

I am trying to say, because colour neg films all have different types of

correct for this, B/W NEG has no such colour in its base, and if you tell
