Photoshop: 16bit masks with panoramas and more

I'm creating some panoramas throught Photoshop. I usually do the following:


Align all layers --> blend all layers (with seemless tones)

The result is in generell quite please, until you look a little bit in detail. There are alway some little problem, which can be fixed. Unfortunately, there are sometimes some issues with the color blending. For example, the blending of the sky.

Trying to fix this, sometimes result in even more weird artifacts. When I use a big brush (+1000px), I will get a smooth blending, but there are some clearly visible blending artifacts. I suspect, this is the result of a 8-bit mask. As far as I know, PS only has 8-bit masks. Another cause could be, the brush color is not calculated correctly.

1. If PS only has 8-bit masks, I request 16-bit masks. Otherwise, I find PS quite unusable.Otherwise, is there a solution?
2. The applyed tone mapping is stored in the blended layers. This is quite problematic, because it produces hard Edges around each layer, which are permantly stored in those photo layer. Make the avaible in seperate layers. I don't care, how many the are, just give me more control.

I think you might be confusing Selections and Layer Masks – Selections are 8bit (so far).

Maybe, but it doesn't explain to me color banding while I'm using the brush tool on the layer mask. I might be able to provide an image as an example later.

Yeah, please post a screenshot with the pertinent Panels (Toolbar, Layers, Channels, Options Bar, ...) taken at View > 100%. 

And just to make sure: The image itself is 16bit?
