I'm not sure I'd want that distinction...

just depends on how often you can do this 5 mins back to back!

in fact she´s got a sister since yesterday! but she belongs to my real sister!

Mac pro 2 x 3.0 GHz!!!

I´m going to meet her tonight to do some benchmark tests!

Try this.. it's free and it works fine

Grab Gimp...
http://www.gimp.org/windows/

..and grab it's normalmap plugin...
http://registry.gimp.org/plugin?id=4485

Install, run and convert any picture or photo into a normalmap.

Well, the latter might create a normal map technically, but it isn't a normal
map in terms of true angle definition. In fact, all the normal maps I use on
my materials are modeled and rendered then in Cinema

Ofcourse you're right Kabe, normalmaps should be extracted from models to be really real. That's pretty much what it's all about. But for all those who aren't familiar with Zbrush and similar software they can cheat like this to get some extra "bumpyness" on their textures.

thanks kabe for pinting that out. Btw now I'd like to know how to extract this data directly within a texture/material photographed, both in the worst scenario when you didn't take the shot, and in the best possible while you are taking it: if this is not asking too much, can you please point out to any whitepaper/resource explaining how this is usually done?

AFAIK it simply can't be done from photographs.

Normal maps are constructed, not sampled. You could create them with a
3D laserscanner (with all the usual drawbacks it has), but there's no easy way to capture them.

But umm.. what about this hehe

thanks kabe and maximus... this forum is getting instructive day by day in my personal experience. thanks again to the people here sharing its own knowledge.

that looks like a dirty hack, sure it works to a certain extent, but I don´t believe it can match a normal mapping created from a 3D model. btw I think this only works for rough textures and not for very fine surface structures, like scratched plexi glas or similar!
