Please bear with me for one more thought.  I actually feel a bit silly for starting this thread instead of digressing a bit and including it in the other one on Sodium Lights.

This is my concern:  Likely my lack of deeper techinical knowledge of what really happens in image color correction is behind all of this.  For instance, with prints or color negatives of prints which show a global color cast, is the real color still there? Does it exist in any degree?  Is the true color masked by an "overlay" of color cast or is the process to take the opposing color and replace the cast?

I do not know if  "restortation of color" is what is happening or "replacement of color" is the event in digital editing of these images. I suspect replacement is the answer. The accuracy of doing this is variable.  All of this got me a bit confused and that is the reason for starting a thread not really needed.

Please reply to this thread or by IM.  Any responses will greatly help me understand what is actually happening.

Cryptojoe, thanks for the imput on the Canon scanner. My HP has a facility but it is not well designed for easy use in scanning negatives.

See all around the site.  Thanks for the input.      Tom.
