Since the dawn of man... just kidding. :D
Here is something i did in last few days, finally i got some time to do something interesting(everyone say this so i had to...)
I have made this scene(staircase to my upper floor) just for one reason, to see how real, good, etc. light simulation is in corona.
Lighting is based on IES files of existing bulbs, no portals, no fake lighting, materials and surfaces are textured as they are, so there is no fake bounces.
Render PT+HD 32PTS everything def. except Exposure comp. 2 and highlight comp. 3.5 (i have raw image that i'm planing to upload later)
Post processing in Photoshop was to add lens Flare, tighten curves and levels and small white balance adjustment and also to give lens distortion, vignetting etc. since i have used regular max cam and it sucks as it lacks bunch of stuff... Also i had to guide by FOV on camera as 17mm in any camera in max don't have slightest resemblance to real 17mm...
Also i have done PT+PT and there was no visible or significant difference(at least on my preview resolution 1200x800)
Photo was taken with canon 5d lens 17-40 f4L on 17mm and as you can see its slightly different as it has some specific distortion, no flashes, no additional lights.
Critique and all kind of stuff are more than welcome.
I would just like to thank you to developers(Steve Ballmer style) :D
I will upload other images(with time stamps, raw, more photos) until then, main dish.
Also i am planing in doing Arion version there is 2.7.6 beta available.
Cheers!
