HI [USER=131152]@puraidodes[/USER]
That is a very interesting observation. From my past understanding and some present investigation, here are a couple thoughts (my understanding not proven experiement yet)
- It is important to know that the softness around a brush is created from the transparency channel and not the color mode (will still be 8 bit even if in 16 bit mode)
- Transparency channels as I understand are always in 8 bit mode not matter the settings you use.
- So I believe the arithmetic computations done may have different "bitness" if transparency is involved
- I also noted that if I set the color mode to 16 bits the transition is smoother (go figure). So give that a try.
So I have not gotten to root cause nor understand Adobe's logic here. I also have not tried all the other modes such as smoothing and flow to see what difference is any those may impact.
I will close with a couple images to make it clear when showing that the edges are controlled by the transparency channel:
Here is a single brush mark on a transparent background:

Here is the same image put pulling out the transparency to a Layer Mask via Layer > Layer Mask > From Transparency (note the thumbnails in the Layer Panel shown:

Here is the same image yet disabling the Layer Mask. Note that a single brush drop is just a color square with transparency:

And when viewing the Layer Mask by itself, you can see that the roundness and edge are controlled totally by the transparency:

Again I have not taken it further other than to provide what I observed on short order.
Hope that helps some
