I have a project coming up that will be a colour photo but it will be about as little colour as I can get on film. Most of this will be just from finding subject matter that is aged and devoid of colour, which won't be much of a problem in the winter, but I also wanted to ask what slide film you guys have used that seems to have the least amount of colour saturation.
Slide film will be my preferred choice, but I can use negative colour film as well.
Thanks
Well, on the market Provia 100F, Provia 400X, Velvia and Velvia 100 are still in production and available without problems.
Yo may have luck in still finding Ektachrome E100G, E100VS, Velvia 100F.
To find Astia 100F is probably even more difficult.
I've used all these films and compared them under completely identical situations:
The lowest saturation have Provia 100F, Astia 100F and E100G. It is not possible to say one of these films has in general lower saturation than the other, because it depends on the specific color.
Example: Astia 100F has a bit more saturation in red compared to Provia 100F, but a bit less in blue.
In the group of the films which are currently in production Provia 100F has the lowest saturation. Velvia 50 and 100 have significantly higher saturation.
Provia 400X has a bit more saturated red (and yellow) than Provia 100F in direct comparison, the other colors are almost on the same saturation level.
My recommendation: Use Provia 100F, and not at box speed, but with a light less speed (0,5 - 0,75 stops) and pull development.
That works great with this film (and Provia 400X, too). You get a bit less saturation and a bit lower contrast (and better shadow detail).
Here are some examples of pulled slide film:
