How Different Fuji Film Simulations Can Affect A Single Color

In-Camera JPEG, single image (not stacked), Provia Film Simulation (click to enlarge)

This post is sort of a continuation of the previous post which you can find here.  When editing the original image of this flower, I found the yellow color was slightly blown out and somewhat devoid of detail.  I knew the yellow detail existed in the RAW file and wondered how the different Fuji film simulations would affect the yellow and if one would show more detail than another. I went through the various iterations of the film simulations and what I found was a huge difference in how the film simulations rendered the purple color.

Below are the various film simulations and how they differ. The only difference in each image is the film simulation as rendered in Lightroom CC.  The image at the top of this post, for comparison, is the JPEG with the in-camera Provia (Std.) simulation of the same image.


First, here is the X-Rite Colorchecker Passport used to white balance the image (click to enlarge)

The exact same image as above but with Lightroom's Profile set to the X-Rite Colorchecker Passport corrected setting.
Notice the dramatic change in color.  This correction is supposed to best match reality. (click to enlarge)
This version is Lightroom's Provia setting (click to enlarge)
This is Lightroom's Velvia setting (click to enlarge)
This is Lightroom's Astia setting, Very much bluer. (click to enlarge)
This is Lightroom's Classic Chrome setting (click to enlarge)
This is Lightroom's Pro Neg Hi setting (click to enlarge)
This is Lightroom's Pro Neg Std. setting (click to enlarge)
There you have it.  You have a wide variety of choices of a single color all from a single RAW RAF file.  I have found other colors may not be as affected as this color, however.

With slide film you had to learn what effect your film had on various colors, blues and purples being the most difficult to reproduce accurately.  You then chose a film according to how you visualized your final image.  Now we can do it easily due to the generosity of Fuji in developing their wonderful simulations and Adobe for duplicating them as best they could—and, I think, they did a very good job.

Thanks for looking. Enjoy!
