Accurate Lighting, With IES profiles....Possible or Not ?

(1/3) > >>

Philip kelly:
Good morning.
I have been setting up a model for a outdoor lighting project. Canopies, poles, street lighting.
I have used the correct profiles of IES, and late evening, or night day light set uo.
But when I render , the lighting levels seem so low they can not be accurate.
Is it possible to get an accurate render out of Corona , or is Vray more accurate than Corona for precise lighting test?

Help would be appreciated.

Thank you

Phil

dj_buckley:
Is your exposure accurate?

What's the full lighting setup?

I'm assuming you've got a dusk HDRI, and then the IES lights, if you've exposed for the dusk hdri and the IES lights seem low at that point, then it'll be the HDRI thats not accurate

Philip kelly:
Thank you for the reply.
How do you ensure your exposure setup is accurate.
I have changed it to Vray to see if I can use the vray lighting analysis, but the result is the same.

No HDRI, the base lighting set up sun and sky, no clouds, and time of 5:30am for example as the dusk shot looks the best as it a bus terminal.

dj_buckley:
Go outside at dusk, take a photo of a similar scenario (with artificial lights) - check what your exposure was?

or just set the lights to whatever you want, the falloff pattern/light distribution of the ies files should at least be accurate even if the intensity isn't

Philip kelly:
if i do what every i want it's not accurate then ....................
