lighting question

[Thejazzshadow]

This is a scene I am working on. How can I see the trees without changing the sun's altitude?

[rcallicotte]

There are a number of ways. Here are a couple -

• Use a method of adding a Default Shader as your Background.  Use an HDR (or similar image) for your Diffuse and then crank up the illuminosity
• Crank up your sunlight and increase your Environment setting for the atmosphere strength

[Mohawk20]

Or you could add a second sun with really low strength...

[rcallicotte]

Mohawk is correct.  There are many ways.  Having a sun with less strength at 180 degrees from the main sun will do it.  Creating another new Environment Light will do it (try using Ambient Occlusion set on low settings).

Hi,

You could change the exposure.

Which would probably be the best solution (why didn't I think of that earlier?!  ).

If you still have the .EXR output you even won't have to render it again probably

The EXR output isn't floating point but 16-bit, so I'd get it roughly right to start with using Jo's suggestion.

I thought exr was a 32  bit? In Photoshop it opens up on mode 32bits/channel

EXR is a strange beast. I don't know the math in depth, and perhaps implementations differ, but, roughly the way it's structured is that it's floating point  but only holds values up to roughly 65k.
(this limits it's usefulness as a zdepth pass, btw, for extremely large scenes... we use .exr's alot at work, but output separate 32bit tiff files for zdepth)
