I just rendered for 20minutes,it still seems that Neat Image couldn't do
a Noise Profile by it self!!!
I have to do it by hand... at this point the Profile works fine, but I will try
to get a better Profile in the future, after learning more about the NI Profile generation!

I also recognized that Indigo's color corection seems not to be OK, the RGB values are not the same

You have any info on how to do a correct noiseprofile in NI ?

Would be handy.. so i don't have to start experimenting again..

cheers

Sorry Dude, I just di it by "Try & Error", I even havn't googel for some advice
Therefor I have to try to optimize the Profile in the Future

Okie will post my expirinces..

cheers

Hey u3dreal...

I read the manual for doing a Noise Profile with a "Calibration Target" Picture.
So I set up an such Rendering, with the image and run some Tests...



After a lot of testing with longer or shorter rendering Times I found out,
that the longer you renderi the CT, the Better the AutoProfiel will be
(means better Numbers in the Noieser Profile Viewer)

But in Real Life testing, this new "über Profiles" loose against the first one I did
My first Profile simply kills more Noise, and keeps more detail!!!

I tested the Profiles mostly with radiance IT Department, because for such
"nearly Perfect" Renderings NI does great work.

I also found out, that after loading the indigo Noise Profile you should NOT do a "Auto fine tune" or a "auto Complete" !

So have fun with this Profile, a call it Final now, until somebody who knows better about NI does a better Profile

Hi Zom-B,

i tried yesterday but couldn't get a clue of NI .. i use version 3.0 ..

Also i couldn't get any noise in the image with a pure white plane.. :rol:
I didn't find out how to make your own profile.
Will have to investigate more.

Any suggestions.. maybe i have to use other version ..?

cheers

EDIT Hey with the target it looks much better .. i get some noise

Ok I found out how to do the profile .. now to try and error..

Yeah this is some old pice of Software on your drive
Check if you could update your Version to 5.x for free, or try to use the NI Demo
for building a Noise Profile that is compatible to 5.x NI...

I just used THIS Manual to generate a Profile, but by using my first "white Plane" Script I get better results in RL Testing!

Also if you use it, use the BW Calibartion Target image, because unbaised Renders don't have problems with special colors (like digicams often have)!

Ah OK 5.0

i'll check that ..

u3dreal

...even v5.5

Just a friendly side note. The expression is "trial and error". Was that German you posted earlier?

he he... thank you! yes this was german...
Some people shure recognized that english isn't my native language
my gramathic in special isn't worth the name, but I'll keep bother you guys
until nick kicks me

I agree with the shared rendering approach.

It just makes sense to refine later more noise areas.
The nosie is for product shots still an issue. Well in
photography noise is rather a nice element. I actualy went
back and do not use any noise reduction in my BW shoots
because the digital mastered images just look to perfect.

But for some degree I would love to see Indigo with a less noise
result depending on the project.


howmany of the coders of indigo are from Germany?

Hey F.ip2...

Indigo is a "one man Army" coding war, taking place somewhere Wellington, New Zealand!
Nicholas Chapman aka Ono-Sendai is the Code Monkey, wo delivered us this nice piece oft software

However, there are more People working indirectly on Indigo, like on Exporters
for different 3D Programms or on GUI's to edit Indigos xml files easily,
or simply helping debugging, support with nice ideas or spreading the "indigo fever" over the Internet

Strangely enough, I've just implemented something exactly like this in my own renderer (Java-based), along with a geometry-aware noise filter (not working with progressive rendering yet but it will soon). Radiance has already asked me to post details of the latter on here but as it's not ready yet, I'll post up details/results of the former in case Nick wants to implement something similar or take some of the ideas.

I also have been extremely frustrated when 20% of my CPU is used to render a v. bright portion of the image that doesn't change even slightly (i.e. after colour clipping/gamma correction) after the very first pass.

Ian.

Would be very interesting if you could start a new
Thread about this when your feel ready for "public inspection"!

This kind of "image based Rendering" is very interesting,
and could speed up Indigo very much I think!

I look forward to your details/results of the former!!!
