Night Rendering - Hospital Exterior

[bKittsARC]

I'm starting to set up an existing project that we did as a daytime render and switch it over to a night time render. While inserting fake massing interiors and light sources behind all the glass I'm starting to wonder what would be a better method for lighting the scene.....

I remember someone (may have have been chris nichols) mentioning the method of just placing objects throughout the scene with a vrayLightMTL assigned to it..... other option would be to place an array of vraySpheres throughout the scene.

I know using the spheres would give me control over parameters such as subdivisions or storing with irradiance, but I'm also thinking that objects scattered throughout then joined as a single mesh object and turned into a light might be better for the scene. I really don't know I'm totatlly guessing here.

if anyone has any knowledge/opinions on lighting methods, I'd love to hear em. specifically if one weighs heavier for rendering times.

Oh yeah and ignore the noise, I rendered this out quikly over lunch yesterday so I didn't turn the settings up much. that being said comments and criticisms are greatly appreciated.

thanks - bk

nice job. Needs some serious warm glow coming from the interior though.

[bKittsARC]

percy....when you say warm glow from the interior, you saying I need to warm up the color on the interior lights, or to that I should create more illumination across the landscape created by the interior lights?

also updated the view a bit..... marketing wanted to see more of building so now I have more areas to illuminate. but I like the new view as well.

The updated image looks a lot better. Keep it up.

I don't want to speak for percy but generally if you take an external shot the light source is yellow / blue on a sunny day and for an interior the light is normally either orange or green in the case of fluorescent lighting. With films for camera, they normally come with a white balance which means that they're taking into account that your photo will be tinted by the light a small amount so what should be white will come out slightly blue in an outside shot, or slightly orange in an internal shot. To counteract this, the film will add orange if you use daylight film and add blue if you use tungsten film.

What happens though is if you have a scene that has both interior and exterior lighting is you get a mistmatch in the film. If you use daylight film indoors, since the film is adding orange to balance out the blue daylight, it makes the orange colours in an interior far more intense. Likewise if you use tungsten film for outdoor stuff, the film will heighten the blue a lot more.

So after all that waffle, what'll happen in the case of your shot is that you'd probably end up using exterior film since your light source will be the night sky. Your interior lights will possibly be orange to start with and the film will make them more orange again. Have a look at this picture for example:

awesome thx for the explanation, it makes sense, I'll start playing with the colors a bit.

I can't hit your link to getty.... it's either broken or didn't transfer into your post right..

Here's another one



For a light to be white it'd have to be pretty intense which wouldn't be comfortable to work in - your eye tends to do its own colour balancing so when you're indoors, white things appear as white but if you step outside and look at a window, your eye is balanced for outdoor light so the bits inside seem really yellow or orange.

update.... swapped hdri's and started to warm up and increase the lighting to the point of burnout. i like where it's heading but I'm not sure I want to go very orange on it. Any thoughts colorwise?

thanks for all the comments so far...

I think some orange would make it warmer and more inviting, and based on joconnell picture not so far from real. maybe you could make the environment around the building darker (especially the foreground with the grass), so the building stands out even more.

[percydaman]

yup, thats what I meant lol. Its looking better. Id warm up the lights inside though, give them a more incandescent look, orangish, and yes they should spill out more onto the exterior, which will draw the eyes in more from the outside and in.

[percydaman]

Alot of it could be done in post too:

[bKittsARC]

wow.... yeah i was worried about blowing it out and making it look like a hot box, but taking that diffused approach really looks good.

And yes I agree about the environment, our monitor calibrator has been outta commission and we just got a new gretag/macbeth i1 in yesterday (who hooo!!), after recalibrating found my monitors were too dark thus my images on your end were too bright and it mainly showed in the dark areas how bad the gamma was off...

thanks for the comments I have to shelve this project for a second, but I'll try to post when i get back to it!

Sorry. Monitor error...
I`ll try to fix my monitor first and will post the image again....

You might want to check your monitor, because that doesnt look too healthy.
