yes, i've done all the basic tutorials.  I am a photographer and understand "exposure".  I included the interior image to show i am capable of using software.
Guess i'm not going to get an answer...thanks anyway.

I'm still confused.  If i have reset everything to 'default', and i get that image called "bright" up above, whats wrong?
I didnt START adjusting sun/exposure etc.  thats where I wound up because defaults ("real" physical settings), give me blown out white image.

suggestions welcome,

Romullus, thanks for the reply.

As mentioned, simply fiddeling with the exposure is not the solution.  To debug this, i deleted the sun and made a new one default values.  Then i created a new CoronaMtl and left it default, assigned to every object in scene.  Finally I hit 'reset settings' in the Render Setup -> Scene tab.   This is my results:

Any help appreciated.

ps. including my first render, an interior where things 'just worked' without much fiddeling

Thanks Brock,

Seems like there SHOULD be a way to do this without post/composite but i defer to then knowledge on this forum.

Maybe I should ask this differently;  is there an 'ambient light' value anywhere?

I suspected as much re: Sun intensity....i'll try to leave it.

Thanks again, any future opinions welcome also!

Hello, Corona newb here so apologies in advance if this has been answered elsewhere but i couldn't find it.

1)  How do i get more "bounce light" into my scene?  I have an exterior scene with a building w/ windows i want to see inside (see image).   I need more light to 'bounce' inside.  I can't fix w/ exposure because that would blow out the exterior...

2)  I"m finding white materials get blown out w/ Corona sun intensity set to 1.0.  Is this normal?  Is it better to try and correct this w/ extreme exposure settings or just lower sun intensity (i've gotten down to .2 or .3).  Or does it matter?

3)  Is there any way to 'force' an old-school reflection map?  I would like specific materials to reflect an image (as opposed to the environment, or some HDR sky model used for lighting).

As always, thanks in advance!  Loving the renderer so far and looking forward to gaining some competence.
