Absolut Indigo

Some of you maybe know "Absolut Wodka" and this here is "Absolut Indigo". The DOF is postwork, made with the Blender Rendernodes. Rendertime was 24 hours (1600x1200).

nice. but where is the bumped logo on the bottle?

and the bottle is too tall, IMHO

why don't you use indigo-dof?

Great image Furumaru.
I don't think your glass/liquids are quite correct tho.
There's a special way you have to model such interfaces in Indigo:

It's a bit of work, but it should result in highly realistic renderings.

The bumped logo was beyond my skills, i was not able to create i nice one.

I use Blenders DOF because i can tweak it easier. In Indigo i have to wait some hours to see if the DOF turns out good.

Very cool picture

You should use Ono's advice for a perfect realism. And if your scene is scaled correctly, you shouldn't have problems to find a good f-stop value.
I can see if there is enough DOF in a few minutes with my AMD64 3400+. You don't have to wait for hours, let's say 10/15 min.

edit : the quoted topic is quite long, but, in a few words :
- add thickness to your bottle
- put a higher precedence to your glass medium than your liquid one.

Here is a screen, what is wrong?

would you share your bottle? i want to improve it a little bit.

That setup looks pretty good Furumaru.
Some things to check are
* IOR of glass should be ~= 1.5
* IOR of liquid should be ~= 1.33 (but perhaps vodka is different?

)
* make sure normals are correct
* precedence of glass medium should be greater than liquid medium precedence - very important!
* precedence of liquid medium should be > 1

Alcohol IOR=1.329
Water IOR=1.33157
almost the same values

Add a meniscus where the surface of the liquid touches the glass.

as this is a mix (I guess, "Alcohol" means pure alcohol), it should have
1.329*(alcpercent/100) + 1.33157[(100-alcpercent)/100]...
correct me, if I'm wrong...
not shure, atm.

however, that is simmilar to about 1.3

You spelt absolute and litre wrong, unless you're using American English or something and then I think its liter. Hmmm.
