  Apple-style screenshot (Message 1 to 8 of 8)

I just wanted to make a screenshot of a window in the style that Apple does -
with the reflection beneath that tapers off.

Since it's not physically based reflection, I mirrored the objects underneath
themselves for a fake reflection, then tried to make them fade out after a short
distance. It turned out that fade_distance, fade_color etc didn't work for me -
they don't fade towards <0,0,0> when in a transparent container, but rather
towards their color multiplied by the transmit parameter - which wasn't what I
expected.

But good old absorbing media worked great. And then I threw in some focal blur
for kicks. Looks OK for my purposes.

Cheers,
Edouard.

Thank-you!

I also tried a lighter surface, and that was much trickier - I ended up using
nasty hacks like inverting the image for the "reflection" and giving it a high
negative ambient term. Crazy, but, again, it ended up looking OK for my
purposes...

Cheers,
Edouard.

Nice look!  Darker one looks a bit better as the lighter first reflection looks
a bit overexposed.  I don't even want to guess what hacks you had to use!

Beautiful, especially the darker first.

Thank-you!

Last one (it's giving me what I want now). Border and text in Photoshop.

Cheers,
Edouard.

Wouldn't that effect be obtained with angle-dependent reflection?

Cool!
But perhaps Photoshop was not necessary... ;)
