Guillermo Luijk has a great page where you can find instructions on how to set up UniWB on your camera, along with settings files. However, Nikon's D3200 will not actually compute a new white balance when you set the PRE white balance from a file. It just copies the WB setting from the file. In order to compute a new WB setting, you must use the Preset Manual / Measure option. So after determining which color your camera sees as neutral gray, take a defocused photo of it.
UniWB is a way to make the camera's RGB histogram show white clipping properly by intentionally setting the "wrong" white balance. It is based on the observation that the RGB histogram is created from the image data after applying white balance, whereas for anyone shooting RAW the interesting data is whether there is any white clipping before applying white balance. UniWB is about setting the white balance to the closest value to "no white balance" that the camera supports. Since white balance can be represented by multiplying the red and blue channels by a constant while leaving the green channel un-multiplied, "no white balance" would have the multipliers 1.0 for red and blue - thus the name "uni"-white balance.

It is said that a company will always create a software system whose organization mirrors the organization of the company itself. This is true, but misses that it is the result of a process in which both architectures evolve toward that point. Neither the company nor the software are fixed, with the other being an imprint of the former; rather, it is the natural endpoint of optimizing the company to produce a given product, and of designing the product in such a way as to be efficiently built by the company. In itself it is therefore not a problem. What is a problem is if either needs to change to adapt to externally imposed business needs, but the other is incapable of following. If you want flexibility in the product, the organization must also have provisions for such flexibility in order to continuously optimize itself to the changing requirements. Conversely, if you want to optimize the organization to meet business needs, the product must be flexible.
A good long while ago I did some testing of Raw vs. Jpeg. Since then a couple of things have happened and now I shoot more RAW than JPG:
Lots of K-Pop dance in this competition. ToXIC$ took home a well-deserved first place, followed by Eviolite.
The nearest thing to a beach walk we have around here.
Biking around.
Lots of color and dance!
Walkabouts.
It ends where it begins.
It's not very action-packed, but kind of fascinating when seen through a close up lens.
One of the few remaining placs in my random walk of Stockholm.
