Re: filmscanners: artificial light



Thomaz,

I don't know what your workflow is like, but picking up on Lynn's suggestion
if you can (maybe in post-processing?) convert to LAB you may be able to
deal with the yellow cast using the B channel.

|
| Tungsten light is always "warmer" by several Kelvins than natural light,
as
| you know. If you can't buy film rated for tungsten light (and I'm not sure
| you can), you can use a light blue filter, which unfortunately reduces the
| incident light you're working with (I don't know the filter
| numbers--photographers and photo shops will be better help here).
|
| Otherwise, if you can set the color curves in your scan-driver, that may
be
| your best way of proceding (I'm taking it that your scanner is seeing
yellow
| in the prints that you're not seeing when you look at them ? ).
|
| Reducing the yellow intensity (or the yellow saturation, as it sounds like
| might be the problem) in Photoshop is another option.
|
| Best regards--LRA
