Wow, nice

I'm interested in how people white balance their imagery.

Do you use the real colour temps for lights, then adjust the final output?

The colouring looks so natural, but I know if I did something like that it would look too orange

Dave

Very nice quality rendering as always comming from you ! And I like the spaces you render, luxury but with good taste, not "too much" or "kitsh" ! The floor patern is nice in this one !

By the way, you could open a gallery-thread regrouping all your renders, i'm sure it would be a pleasure for the eyes!

woah!

somebody should check your camera's WB... it seems a little off

Mr Whippy: Hi Whippy, I use 4500K color temp, I adjust final image in PS (Saturation). Yes the original rendering much orange nuanse.

tokiop: Always nice comments. Thanks Tokiop, good idea to grouping my rendering.

Leonardo: Hi Leonardo, I like your adjustment. How do you adjust WB?

depends... in your regular camera look for something like WB, in renderings use photoshop.
Maxwell doesn't have a White balance function yet
The main problem is that you probably used the correct type of lighting to lit your scene and maxwell is simply showing how it would actually would look. (so far so go )
"However", the human eye compensates for the yellowish color so if we where actually in the lobby we would not perceive so much the yellow tone.
That is why digital cameras have something called wb, so the can adjust the tones of the pictures depending of the situation.

Maxwell doesn't have it yet
If you want me to go over how I did it in photoshop, let me know
Leo

Thaks Leonardo, I used Level & Saturation adjusment in PS, am I correct?

yeah, you can select in the hue/saturation - edit - yellows or reds and then click in one of your walls... photoshop will find the range and you can de-saturate the wall

Wow thanks Leonardo, i will try.

Problem is adjusting after rendering with a low dynamic range output means you get a loss of information, and interpolate some new info.

Notice how you can adjust a real jpg's WB from your DSLR, but it gets bands, wheras if you adjust the WB with a raw image you can select the right range of colours.

A good idea is to place a neutral colour in your scene in a test render to use as a sample for the colour offset, and then use it to balance the scene in photoshop, but it's still not doing it with the full data range that maxwell see's in the mxi.


I was just wondering if anyone had ever adjusted the colour temps by % to get a neutral scene object material to be neutral in the render, by sending maybe some of the white lights into blue, and the orange lights into yellow/white?

I'm not even sure if it's linear and thats the best way. Just thinking that Maxwell is really limited here, why even use real colour temps if you will then adjust them perceptually, or a better method but undermining the rendering accuracy, editing the LDR image in photoshop afterwards.

I hope we get a WB soon anyway, it's as fundamental as having your f-stop adjustment really

Dave

Yuo are right. Let's NL to implented WB.

why we have no WBalance in maxwellrender yet ?
is it hard to implement ? or everyone have PShop 5, then it is pointless ?

I too would love a White Balance setting that can be tweaked after a rendering is done, much like the Camera or Tone Mapping settings currently work. I do fiddle with the Sun Temp setting but a post rendering effect would be so much more useful. And to make things more awkward for myself, I'm in the habit of rendering my images out to 16bit PNG files which Photoshop does not seem to want to open as Camera Raw files for me to do White Balance corrections on.
