I would like to create some Mac OS X 10.7 Windows "simulations" in Photoshop.

I would like to learn about the window's shadow parameters, like size, spread and distance.

Could anybody help me with this???

What version of Windows are you trying to simulate. – Mort Dec 4 '12 at 20:07
Are you just asking about shadows? Or is there something more? – bassplayer7 Dec 5 '12 at 0:49
I am not trying to simulate Windows, I am trying to simulate Mac OS shadows – Victor Dec 5 '12 at 20:49
@bassplayer7 I am talking just about the shadows, I already have made the rest of the frame – Victor Dec 5 '12 at 20:50

For Mac OS X standard windows use drop shadow with folowing parameters: black #000000 color with opacity 60%, angle 90º, distance 25px, size 50px, spread 0px.

As of the latest OS X release I believe 50% opacity, 22px distance, and 45px size more closely approximate the drop shadow. For retina displays, 45px distance and 90px size. – Christopher Swasey Jun 22 '15 at 14:00

Actually it's more of a combination of two drop shadows. These settings work well for me in direct comparison to the original shadow:

  • Dropshadow 1:
    • Opacity: 47%
    • Angle: 90°
    • Distance: 26px
    • Spread: 0px
    • Size: 43px
  • Dropshadow 2:
    • Opacity: 44%
    • Angle: 90°
    • Distance: 0px
    • Spread: 0px
    • Size: 3px

The second drop shadow is for the fine darker line you notice around every window, especially when examining OS X window chrome on white background.
