Maxwell Render | Official public forum

Hi all,
Can anyone suggest a decent program that reduces noise in Maxwell renders? I remember seeing several mentioned, and did a Search, but got tired of reading posts that didn't mention anything.
PS Sharpen is *not* the ticket.
TIA,

If you are using paintShop pro, there is build-in camera-noise-reduction function which is doing surprisingly well. (under Adjust-->PhotoFix)

Otherwise, I would recomment NeatImage (it did a better job than NoiseNinja, back when I tested them)

Thanks Thomas,
NeatImage is the one I was trying to think of.
I've got PS CS2.

In that case, why not use photoshop's own noise reduction filter? It's in Filter > Noise > Noise reduction.
Just play with the sliders.

Sharpen is def. not the way to go

Hi Renze,
I tried that, and wasn't really happy.
So I thought maybe a one trick pony would be better.
I'm also look for an "Adds Dispersion" package for diamonds.
Going to SL18-20 gets times consuming. I'm at hour 30 on one now.
cheers,

You should also first look at the different channels, and see which one holds the most noise. Ofcourse unsharp mask will sharpen the whole image, including the noise. What you can do instead is find the edges of the image first, and then "sharpen" only those (that's what Unsharp mask does, it increases the contrast between pixels of differing values ie edges).

There's a good tutorial here about finding the edges, and then running Unsharp mask:

Neat Image is very good.
