Cedrone Lighting test + milk

[jjaz82]

i like Cedrone Photo for me now he's a reference for art of photography and stile mood. i wanted try this simple setup lighting, and in the same scene testing a sss setup of milk,
this is my first fast attempt for set up light and milk, other materials are only placed in the scene without any correction, they need more work.
ceiling material its wrong.
 if you have any advice, you are welcome :)

Doesn't look much like milk. Unless it's what Cartman drank in South Park episode, where he accidentally put Kenny's ashes into milking thinking it was cocoa :)

[jjaz82]

hahaha :) i remember that episode, i will search more references..but it's hard to find milk on backlight setup

Your photo references of milk show very thin layers of it, this probably misguided you. I think milk is less translucent.

[jjaz82]

mm, you are right.
i'm trying this setup now.

in absorption color i use this rgb

Honestly these settings are confusing for me. From what I learned absorption colour's value also affects absorption's distance. So setting darker colour is the same as setting lower distance value. Am I right? And darker "scattering" colour will make the object look more dense and lighter will make it look more transparent?

this is a definition in corona help..
absorption is controlled by setting the color that original white ray will have after traveling specific distance in the medium.
in my test the color i sselect in this parameter generate different sss color

[jjaz82]

if  increase distance parameter you can see the color i used in abs

last milk set up
in the second render i used same milk setup but on direct light.

Looks too dark to me.

in both image or only the first?

[jjaz82]

That looks a bit better :)

all colors are near to pure white (255 255 255), with a little part of yellow, maybe it's a illumination/contrast problem
