Final Major Project: IoP Symposium Workshop – Film Scanning – 17-02-18
The second workshop that I attended at #iopSymposium18 was a film scanning workshop. Each participant brought along negatives to scan. I decided to scan both colour negatives that I took with me and the black and white negatives I developed earlier in the day.
The workshop covered the following topics:-
24 bit vs 48 bit
24 bit = 8 bits of colour per channel
48 bit = 16 bits of colour per channel
you will notice the difference mostly in the smooth gradients of colour (eg in sunsets etc)
you will not notice a difference in contrasty images
more information is better for working in Photoshop afterwards
All monitors are 24 bit, so if you are only displaying online then 24 bit is sufficient
48 bit is better for printing
48 bit files are bigger
Save files as TIFF to retain all the detail

Images are scanned in reverse with the emulsion side up
