Hi sorry yet more questions from me. I decided to buy a relativly cheap
scanner. Minolta Dimage IV (3200dpi) on the principle I could not justify
the cost of a 5400dpi film scanner. the aim was to scan some hundreds of
print film negatives with as accurate and repeatable results as possible
with minimum fuss.

I would agree with observations on this list that colours are less
saturated and that the result is less sharp when scanned. (I have not
tried manual focusing)

At the moment I only take colour prints and have never use slide film. I
tend to use Fuji 100, 200 and occasionally 400 ASA film. However, when I
scan the negatives using the software supplied with the minolta I don't
get consistent results in exposure and colour ballance from day to day
scanning the **same** film frame! I was not sure if this was a rubbish
scanner or rubbish software so I decided to try some different software.
after a web search I found  alternative software which supports my
scanner.

I tried the software and can get consistent results from the **same**
frame but **even** **more** **widly** **inconsistent** results between
frames on the same roll. (I should mention the prints I got back from the
film are fine). These scans where made with the *lock* *exposure* and
*colour* *ballance* settings. so the software does not adjust the exposure
and colour ballance for each frame individually.

So the quesition in my mind is, bearing in mind that the developed photos
look fine. what is going on?????????????????????

1. is scanner *correctly* seeing large differences between exposures on
the same film which is being compensated for by the developer when they
make the prints. This would imply either
           1. My om 3's light meter is not consistent
           2. I am rubbish at controlling the exposure!!!!!!!
           3. Its the nature of print film and not to worry
or
2. there are not large differences in exposure between shoots on the same
film and that the scanner is not consistent. (however scanning the same
shoot on different occasions with scan view give consistent results)

3. I should just let the ascanning software automatically set the exposure
for each shoot and not worry about this at all.

4. I should start taking slides and forget about print film because it is
too inconsistent.

5. other alternatives welcome!

Yours confused!!!!!!!!!!!!!
James
