Backgrounds and overexposure correction

Anonymous
Not applicable
I've Just spent 20 mins wondering why some beautiful white fluffy clouds on a backround image I'm using in a render are coming out a dirty grey.

I found it's actually the overexposure control darkening the background.

Out of curiosity, why is it set this way? Surely you would be happy with the levels of the background image before using it? or is it a bug?

Cheers!

Nothing there to be cheery about.

You mean that your Archicad Photorendering Brightness is set to darken the the entire image if overexposed rather than just the overexposed parts?

There is often no explanation for an erroneous setting. My take is that they have it set for duffus skill levels.

The Brightness control is a bad control in any event because unless you have a large display, it collapses and any slider position is captured to the detriment of future images.

It was set by default on 'darken overexposed surfaces'.

I found changing it to 'paint overexposed surfaces with' seemed to leave the image as I wanted it. Weird!

Thanks anyway.
