Mask feathered not sharp

[vanderblom_photography]

I'm trying to do a simple sky replacement in photoshop, but my masks are blurry when I select and mask and not sharp at all. I am not feathering, but just using quick selection, select and mask. 

as seen in image:

1 I make the selection with quick select

2. I check the selection (in Lumenzia) and appears sharp just as I need

3. when I select mask I get a blurred/feathered mask as seen in image 4

4. The mask itself

5. result of the effect. No sharp crispy lines between sky and mountain, but feathered. 

It drives me nuts. I cannot figure it out why it does not give me the mask as in image 2.

Thank you for your help! 🙂

Hi @vanderblom_photography! Thank you for reaching out! Have you checked your mask properties? The most likely culprit is that the Feather or Smooth sliders in the Select and Mask properties panel are set to a value greater than zero.

Make the selection using quick select or object selection > Select (at the top menu) > Select and Mask > In the Right panel, check Global Refinements and make sure Smooth and Feather is set to 0. You can slightly increase the Contrast to harden the edge if needed. You can also use Shift Edge to contract or expand the selection

Hope this helps!
