Just starting to acquire some ND filters (Formatt Hitech and VU, 100x100 and 100x150mm) and filter holder (breakthrough photography x100, still waiting on proper mounting ring).
I understand some filters will change the color tones a bit. Those of you that use them, do you adjust your white balance in the camera or PP? Do you use polarizing filters in front of the ND, or between them and the front of the lens? Thanks.
If your ND filter is of high quality, and most 100x100 or 100x150 are, you won't see any chromatic aberration. If you do, Lightroom's Lens Calibration panel will take care of that.
Aa to the CPL, you put the polarizer on the lens, then the Breakthrough adapter ring on top of that. Use the Galen Rowel method and adjust the CPL, then with your fingertip on the CPL so it will not move, insert the filter over the front of the lens.
One tip: Keep the X100 in its red/black case when in your camera bag. I had it loose for several months and the little red knurled knob vanished somewhere in Yosemite Valley
Breakthrough was really cool and sent me a freebie replacement and the two springs that I also launched. A small drop of Loctite, and using the case, solved the problem.

I use the VU 150x150 and 150x170 filters, Schott glass, multi coated, and no color casting.

Do a test and see. I usually use custom white balance, which lets me start from neutral in post. Again, test to determine whether your ND and polarizer work well together, and which stacking order works best. Beware vignetting with wide angle lenses.
I started in film. A very common practice was to take a picture of an 18% gray card or a MacBeth color test checker under ambient light with all filters in place. That gave us a solid reference point in the darkroom. I still follow that practice today.

All ND and polarizing filters will have a color shift. Shooting raw will give you a wide latitude for correction in post. If color in a scene is critical, and it is practical to use a calibrated color target, I will use a ColorChecker Passport. This way there is zero guesswork. And the price of a filter does not indicate the amount of color cast. It's not unusual for a filter that blocks visible light to allow infrared to come through, resulting in a magenta cast.

And providing you select modestly price filters that do not add other flaws like loss of contrast from poor quality coatings, you'll be fine.

I have never changed any ISO in pp, that I do only in-camera, always. It is the first thing I set, one glance to the outside and I know my ISO setting!
Thank you all, very helpful.
