Does anyone know if there is a way to create glare in Poser?  Not sure if that is the right word, but what I mean is when you are looking at a photo of a bright window in a dark room, the brightness of the window creates a kind of glow around the window, at least if you have not adjusted the white balance.  I want that kind of whiteout effect when its too bright compared to other things in the picture.

Thanks for always being helpful!

If I imagine correctly what you are trying to do, yes there is (sort of)... at least one way comes to mind. As you say, if you adjust white balance on a digital camera the effect is reduced or removed, and with 'wet process' film it's a result of scatter on the film through the lens (no white balance on wet film). Poser does not pick that up. Atmospherics will give the light beam effect, high light settings will give the washed out light in the window, but no scatter around the inside of the window. What I'd suggest is trying a shape inside the window that is invisible to camera but has an ambient value of its own. A one sided square facing the window might(?) only cast light at the inside of the window and won't impact the other lighting. If you have an actual mesh light, it should do the same. You'll need to fiddle with placement, intensity and scale to limit the spread of the inner glare, but it'll give a reasonable approximation.

BTW, I'm sure there are other ways to do it.

So here's atmosphere in use...

and here's a washed out window...

These two are JUST lighting settings. There is no specific 'glow' on the inside of the window frames. If either of these suit, there is no need for fancy back scatter lighting set ups.

Thanks so much for your response!  That was a very good analysis, and your examples are great too.  Its a bummer that it is such a manual process to achieve this effect.  There is a glare feature in Carrara that can accomplish this, and I was hoping that it could be that easy in Poser too.

Thanks again!

if you post render of desired glare fx in carrara, they may be able to replicate that in poser.
