The X pro 2 camera from Fuji is an exceptional camera, and Fuji has taken everything that was wonderful about the X pro 1 and brought it forward with very up to date technology.
One of the things that was added, besides the Acros black and white film simulation was the ability to add grain. Not noise, but actual film looking grain. I have had the camera a few months and really backed off using this feature and for that matter even considering it. The main reason was the fact that any simulations that are used for the Jpeg files do not appear in the raw files and I have been using mainly raw files. That may change if only because it is really difficult to try and duplicate what Fuji has created with the Jpeg engine.
Yesterday it was hot, muggy, very cloudy, and really not a very nice day to shoot much of anything outdoors. So I brought a little bit of the outside inside and decided to run a minor test using the grain option in the Fuji X pro 2.
I set up a portable work station, added a black drape, worked with available light.
1-I shot the Acros black and white, using no filter. 200 iso. I first shot it with out adding any grain. Then I added heavy grain and then weak grain.
2-I then did that for Acros, but this time also added the yellow, the green, and the red filters and followed the same shooting pattern.
3-Then I shot the Acros with no filter but with strong grain and at 3200 iso.
4-Next I should the standard provia simulation using the same procedures and the last shot was strong grain at 3200 iso.
5-Finally I did the same exact procedure with Classic Chrome.
All of the images attached here are labeled as to how they were shot so you can judge for yourself. If you would like to get original files let me know and I can send you a zip file.
What I found is that the grain effect can be very pleasing both in color and black and white. Unlike noise, the grain is very much like film but not exactly. Fuji being the film experts they are have done a pretty good job but like with everything else we all have different tastes.
