negative to positive strange results

Just an explanation for anyone interested in what that negative is.

After doing some research I found out it is called an internegative which is "the second negative of an image made from the original negative" which is used in the motion film industry. In 1979 I had done some work in the movies which completely slipped my mind.

Here is some more information in case anyone is interested.

https://en.wikipedia.org/wiki/Internegative

An invert adjustment followed by a curve gives a good starting point. For the curve set the blackpoint with the eyedropper to the mask colour (sampled from around the edge). If there is a known white, set the white to that - then tweak and crop as required.

It is important though to start with a well exposed negative and a scanner capable of cutting through the density.

Try using a Curves adjustment layer with the Color Negative preset.

This preset does a reasonably good job, but some tweaking is usually required.

Color negatives are difficult, as they have an orange mask that varies with density, and was used so a lot of filtration didn't have to be used in the enlarging process. From the scan, it looks like you underexposed your scan, as the invers is much to light and washed out. How are you scanning the negs: actual scanner or shooting them with a camera? Cheaper scanners also have a very limited gamma range, so if your original neg is over exposed, which it looks like from the scan, the scanner may not be able to make a scan light enough to compensate. Most scanners that can scan negs also come with software that converts the image. Doing so in PS isn't easy.

Can you post a higher resolution sample?

Anyhow,

• Use Layer>New Adjustment Layer>Levels
• Select the "White Point" eyedropper:

• click in an area near the sprocket holes that is the "base" orange colour to remove the orange cast.
• Use Layer>New Adjustment Layer>Invert to invert the image.
