An interior render. Thanks to suomi for sharing the background image.

I'm still playing with relighting options at the moment:-

Photonmapping with three area lights. One at each window and one fill light to the left of the camera. The other window is to the right on the same wall as the visible one.

Great Work! :shock:
And now is the time for the questioning! :lol:

1- How much power have you put on each of the three lights?
2- Is the plane outside emitting light or just the material?
3- Gamma output was linear (1) right?
4- Did you use the compositor or gimp? Can you share the process?
5- I would love to see the raw image. Can you share it?
6- Have you tried compressing a bit the tonal range of the darker grey areas? It would be similar to reduce the fill light a bit.

And thank you very much for sharing such a nice work.

P.S.:My favourite part of a render work is when we achieve a raw image that has quality enought that allows playing with the yafaray exr. I really feel like i am working in a dark red room back in the kodak days... :)

Light 1 - 15
Light 2 - 7
Light 3 - 0.7

It is emitting, but only to ensure it is overexposed.


Arquitecto wrote:3- Gamma output was linear (1) right?

Yes

The compositor. The node tree is probably a bit messy just now.

I have three raw images. I rendered each light separately. When I began lighting I realised there were many options so I made sure I had all the raw data available. Mainly there is the 'natural' light coming through the window, and, as a photographer I would want a large reflector to light the shadows, which is light 3. I can share the .exr files tomorrow hopefully.


Arquitecto wrote:6- Have you tried compressing a bit the tonal range of the darker grey areas? It would be similar to reduce the fill light a bit.
Yes, I am still playing a bit with lighting options in the compositor. i want to try subtly colour correcting each light to get a more natural look.

One thing I learned is the benefit of colour management. The two images are with Blender colour management on, one using the monitor profile, the other not. The top image is what I see in the render window, and the bottom image is how it really looks in colour managed Gimp(or Photoshop). The difference is subtle, though effectively it means I routinely overlight the shadows in all my renders and i don't see the true colours. Though not any more, thanks to troy_s. - http://wiki.blender.org/index.php/User: ... Management

Open each image in a browser tab and toggle between them. I should say this render was already running before I set up Blender's colour management, otherwise the saved imaged and the render window would be identical.

EDIT - Here are the rendered .exr files, and a z-buffer:-

If anyone wants to post their composited images here, I am happy to use this thread as a venue to discuss Yafaray and Blender compositing. If you want to post .blends with node set ups that would be good too.

Hi once again,

I love your scene.
It's very cool to have diferent exr to play with light power.
It's interesting that it was so well balanced that I haven't changed much the light power after playing with it.
My test is just a matter of taste.
I like the window zone always a litle bit overexposed when we have a natural source of light in front of the camera. That's just the way traditional photography would look. But of course some may disagree...
Anyway, is dificult to do better on such a nice work :wink:
Enought talking.
Here is the blend and the image.

When lighting interiors, each scene is different, and the render settings should be optimised to suit the individual scene. You would learn much more by reading something like this instead of copying settings for one scene that may not be compatible with another.

@ stoneage

You didn't make or use z-depth in the Compositor for the final image.

What the Render time:
-Lamp-01?
-Lamp-02?
-Lamp-03?
- Z-buffer ?
