I have my trusted FotoSharp Day & Night Exposure Guide, but what should work, doesn’t. For example: Front lit - Sunny Day should be ISO 100 f/Stop 8 Shutter Speed 500 But, this produces a dark render when using VrayCamera and VraySun/Sky. I have to drop my Shutter speed down to 250 for it brigh…

because you’re “photographing” shaders, for which the albedo (total reflectivity, or brightness) doesn’t necessarily match your control conditions (unless you scanned the materials in.). Further, are you under Linear Workflow? If not, that will also contribute to it all. Thirdly, it may also be t…

a sunny day in miami could be 1/2000, and one in england might be 1/50. Stop following a rulebook. do a low res test, if it’s too dark, make it brighter. who cares what the numbers end up at.
