Edge Burn???

I've been noticing quite a bit of what I call "edge burn" on my scans
of 35mm negatives. It's either a brownish cast at the right edge of
the frame, or circular-shaped darkening at the corners of the image.
Are these natural and native to the negative, or is this a scanning
problem? Is there any way to get around it or compensate for it?
(I'm using VS 8.0.8, at 1800 dpi on a Epson Perfection 2400 on a Win2K
machine.)

Thanks -- Bill

One does not normally scan the whole width of the negative, just the 24mm X
36mm picture frame.

Set your cropping to include just the image on the negative.

Also be sure you are not covering the calibration slot in the negative
holder.

Maybe it is flare from the transparent edges?

You could try and make a mask, to cover the edges.

Thanks, Carl ---

I'm not sure I understand your response. I do scan the entire image,
though I often also get some of the black film outside the image
(between the exposures). Are you saying that this is my problem?
That including the unexposed film in the scan causes the burn in the
image? (hmmmmm ... this is starting to make a little sense.)

I also don't know what you mean by the "calibration slot in the
negative holder".

There is a notch in the top of the Slide and/or negative film holder
that is laid on the glass to scan transparencies. It must not be covered!
The scanner uses this slot/notch to calibrate to the light source.
