35 mm Slide Conversion

Post by Starry Eyes »

:?: I'm getting some Astro slides from the 60's scanned into 48 bit Tiffs. Will STools open these or will I need to convert to something else, and how?

Cool! They should open as long as they're not compressed. If they are compressed you can use a free command line tool like Imagemagick's "convert" tool.

Code: Select all

convert input.tiff -depth 16 +compress output.tiff
Of course, any other tool that can deal with 16-bit TIFFs will do just as well.
Would love to see some of you results!

Note that film-captured scenes are no longer linear, so make sure you let StarTools know...

Many of the photos were of a total lunar eclipse in 1969. A very colorful one. Taken with an 8" F6 Cave reflector on Kodacrome slide film. I suspect that there has been some color drift caused by aging of the film. How to correct that will be one issue. The longest exposure was 55s @ totality. How non linear that will be....
