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".

RAF 50.5MB:

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 morewith 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.


I am just happy that we could keep this related to digital photography,
and I am glad there was an aspect of the thread to lure you in.

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.


In my wet darkroom darks it was working with Tri-X along with various
Ilford and Agfa films, with different developers at different
concentrations and temperatures. However, my wet darkroom equipment is
long gone.

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.


It certainly evokes a sense of nostalgia for me.

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


In that case I highly recommend testing the Alien Skin Exposure X2
trial. It was meant for folks such as us. It also does a pretty good job
of most processing tasks for RAW and JPG. These days I find myself using
some of the alternate tools as much if not more than my usual
Lightroom/Photoshop workflow.

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


Nothing wrong with that. Enjoy!

Enough for now...



The Alien Skin stuff looks interesting. I'll likely try it out one of
these days.


It is actually not too tough to work with. They have some videos to get
you started, and they have more tutorials on youtube.
Just remember, it is just a 30 day trial, and I have been happy enough
to pay for it.

For now I'm content in re-exploring grain. I've done a bunch of experiments
and learned a lot about different ways to add grain as well as ways to
mess with grain statistics. Much left to learn. I'd like to learn more about
the difference between high ISO digital noise and push processing,
grain popping noise, etc.

Too bad others haven't joined this sandbox.


I guess it was too closely related to photography, and not enough
bitching for the usual suspects.
It was worth a try. ;-)
