Very thin, very dense, and very contrasted negatives (i.e. over or
under developed, or poorly exposed) can be particularly difficult to
scan. We will try if requested but the risk of muddy/noisy scans in
these cases is yours. Generally speaking, if you can print the neg
reasonably, it can be scanned reasonably. Chromagenic film (i.e. C41
process) scans very well and we recommend it.
In short:
Colour from negative film is very tricky, as negative film varies so
much. We'll do our best to produce natural and accurate colour, however
please be aware some final colour and density balancing will always be
required.
In detail:
Colour negative is HIGHLY variable stuff, and it's extremely difficult
to get anything resembling 'reliable' (i.e. accurate) colour from a neg
(scanned or printed, doesn't matter). The reason for this is,
ultimately, the orange mask and the completely variable processing of
colour neg that occurs. This is one of the main reasons for
transparency film is typically used when colour accuracy is required
(and even then, there's more variance between film runs than you might
think, which is why ColourChecker charts and clip tests are part of the
further arsenal of techniques and equipment required for colour
consistency).
When
we do a neg scan - we do not completely colour balance files, or aim to
colour match proof prints etc. We aim to get maximum detail from the
neg and put the image in a position whereby a small amount of editing
will get it into very good shape - with around 5% movement or less
(i.e. close, not massively out, but not 'bang on' to some arbitrary and
subjective judgment). The result is scans from the neg that are likely
to be flatter than you expect (deliberately, to retain maximum detail)
and close, but not yet perfect colour. The goal is to put you into a
good position for fine print work (i.e. maximum detail) rather than to
provide perfect colour (since we ultimately have no reference point for
that anyway).
In doing this, we start from a base point with
respect to a film type. From there, depending on what has been supplied
and the conversation we've had, we may or may not tweak the base point
slightly in some direction. We don't promise to do this, and we don't
consistently do this - in fact, it's generally our policy NOT to do
this as it's very subjective and fraught with peril - an adjustment for
one image will most likely not suit another, thus 'fixing' one will
throw out the next, and before too long, we're in trouble. In the end,
you're best off making these adjustments for yourself post-scan. The
adjustments are typically minor, and obviously you're the best person
to make decisions about your images. It's important to understand that
the scans are (deliberately) somewhat unfinished and only one part of
the whole process of achieving the fine print.
Print Matching
Following
on from above, we don't offer a print matching service. We scan what's
on the film and aim to give you all the information the film can
contain - we're happy to use your prints as a guide but we'll aim to
retrieve what's on the film more than we'll aim to produce an exact
match of a low quality proof print.
