[filmscanners] RE: how to scan 'red' 'green' or 'blue' lights?



Frank and Paul,

I prepared two examples and taught myself a lesson in the process.

Here are two images:

http://www.tallgrassimages.com/test/Azalea_example.tif

This is a snip from a full-res scan on the SS4000. The film is either Velvia
or Ektachrome Elite Extra Color (I have the slide filed away and I didn't
label the scanned image). I included some surrounding foliage for
comparison.

Working with this image in Photoshop (Adobe98 colorspace), it appears overly
saturated with the reds of the azalea blocked up.

After I FTPed this image, I looked at it on my website with Internet
Explorer. My system uses a QuickTime plugin to view TIFFs. I assume what I
am seeing with QuickTime must not be color managed as the colors are much
less saturated and yes, as Paul suggests, I can see much more detail in the
reds.

I posted this second image which I purposely overly saturated:

http://www.tallgrassimages.com/test/Azalea_example_more_saturated.tif

So it looks like what I assumed was a technical color problem was actually a
color management mistake.

It's a good thing I have a regular day job doing something else...

Stan

I expose Velvia at ASA 40. I'm using VueScan.

We basically have three varieties of Paintbrush: orange, pink, and red.
There are intermediates as well, probably hybrids. Sometimes the three
basic colors grow right alongside each other. The reddest reds are
something to behold: almost unbelievable.
