OK! I found an inoffensive subject for those folks who would like to
play.

So here is the SOOC JPEG Acros rendition (14MB) with the RAW file
(50.5 MB RAF), and for the folks who just want to peek without
dealing
with the big files, a resized JPEG (791KB).
With LR or ACR the Adobe version of Acros is available in the Camera
Calibration panel.

If you care to try AlienSkin Exposure X2, they have a 30 day trial
(works as stand-alone and/or as LR/PS plug-in).

Their Acros simulation is found in their film presets as "Fuji Neopan
100 Acros".

As I have said, I can get pretty close with Exposure X2.

OK, I managed to download the files and converted the RAF to DNG
I couldn't find anything in ACR's Camera Calibration panel.
The only Camera Calibration listed is Adobe Standard.

The Acros Camera Calibration only shows in ACR if the RAF is used. What
I can't say is whether or not the ACR updates for PS-CS6 include camera
updates. I understand that while that version of ACR doesn't include
some of the CC feature, they maintain camera updates.

So, I opened the DNG in my Photoshop and converted to B&W.
After some minor gymnastics I got quite close.
[There's some discrepancy in the dark gray.]

Anyway, here are some of my test simulations:
Test (No Grain)

Not bad at all.

Test (Some Grain)
https://www.dropbox.com/s/hcxldrc5lz54zmf/Test%20%2301%20%28grain%2001%29.jpg



Not too bad, but the grain quality is not quite up to the SOOC JPG.

Test (More Grain)
https://www.dropbox.com/s/r1clsukndvwn5fo/Test%20%2301%20%28grain%2002%29.jpg



That one seems to have been pushed too far and the detail is spoiled
rather than enhanced. The quality of the grain is way off.


I haven't played around with conversion to B&W or with film
simulations before.

I knew the grain in that last test was over the top. I need to
experiment a lot more
with grain algorithms/procedures. I need to learn more about grain
statistics.

It's been an interesting exercise and thus a learning experience.


I look on all aspects of digital post processing as a great learning
experience, but most of all, for a retired old fart, it is fun.

Here I took the RAF into Exposure X2 (no Adobe LR or PS) for all of the
post including a 16:10 crop, and an Agfacolor Neu film simulation. All
of these things gets us to a very different look.

Actually, it was the discussion of grain simulation that got me interested
in this thread.

Back in the deep dark past of my wet photography days I did a lot of
experiments with synthesized grain. Back then I used a ground glass
plate on top of Kodalith to create various grain effects.

The discussion brought back some fond memories of those days
and those experiments. Photoshop allows me to experiment with
techniques I'd only dreamed of back then.

I find the exploration of realistic (simulated) film grain vs artificial
artistic grain effects fascinating.

After all these years I still tend to go for artistic renderings over
realistic renderings.
