I have just begun trying to scan some old SLR slides and negs from a few decades back. I am using a Nikon D5100 with a Sigma 150mm f2,8 lens stopped down to either f16 or f20.
In the scans I did yesterday, it would appear that the structure of the film (not the grain,) has become very evident. This has happened on both slides and negatives which have been stored in protected boxes and sleeves.
I am not sure what is happening, as even using noise reduction techniques in Lightroom and Photoshop does not make a great difference and often softens the image too much.
I was using an old slide viewer I had, made by Hanimex call a Simon Slide Viewer as the backlight. It wasn’t that bright and I just wonder if this could be the issue?
The upload demonstrates the problem, especially in the sky.
Any hints or tips would be much appreciated.
