Question

There is an enduring discussion about the advantages of analogue versus digital or digital versus analogue. A new series of articles about this theme will be published soon on this website. Below is an example of a small section of a file that was the result of a scan of a negative of the Kodak Vision 3 film made for use in a standard 35 mm camera. In this case the Leica M-A with Summilux-M 50 mm ASPH. Exposure was made with the Gossen Starlite-2. The negative was scanned with the Nikon Coolscan 5000 and processed with Silverfast software. The small section shows several important aspects: there is no grain (not surprisingly: ISO 50!), the dynamic range is indeed very high: see the details in the dark parts. Most interesting is the performance in the specular high lights. There is no smearing as is usual with digital capture, but there is a strange red halo around the bright spots.
The question is: what is this? Send answers to my email address: erwinputs@kpnmail.nl
