When to use the physical camera?

[Marshall_Craft]

thank you for the suggestions, but I didn't use the physical camera or the vraysun/sky for this shot (not yet at least.) i was hoping someone would be able to tell me whether or not jacking up the vray plane lights' intensity to show up when using a vray phys. cam would screw up anything else or would hinder render times. i would try it for myself, but I don't work on 3D all the time. Any advice on this would be greatly appreciated.

Thanks.

Tammo, do have a go at the tutorial i prepared a while back (big thread in the tips and tricks).

well Alex i don t think it will increase ur render times...it will make u go through a lot of new stuff, i suppose...so jump in phisycall if u have the time really

...oh and if u do, lele tm s tutorial is gr8 to get started!

[Marshall_Craft]

i've used the phys cam a couple of times before...but that was just for an exterior shot, so i only had one light source (i guess two with vray sky...) anyways, i just need to finish downloading lele's tutorial videos. thanks for the help!

Nice tests Nikki.

It would be cool if this could be done at real-time in the VFB. Sorta like how PS use's a colour temperature slider, when processing RAW images.

yeahhh....
long time posted on the whishlist...

Hmm, time for a bump then ..

EDIT, If I could find it

White Balance is cool, but I always wondered... why not just do that in post? Outputing full float means you can stretch those images like fresh bubblegum.

or th "s-curve" in photoshop (daforce tm)

true-true

use whatever makes u more confortable i d say!

The only reason not to do it in post is that the price of combustion, fusion or nuke is a lot steeper than the cost of a VRay license.
This of course, as i do not include Photoshop as an HDR compositor.

Those who can, surely will opt for Post (selective, realtime, and whatnot), but for everyone else, it's a great addition, imo.
Very much like for LWF and VFB curves.

^ For photoshop HDRI work, I offset that by getting my full float image, changing the exposure and flattening, then doing the same with another exposure (higher/lower). Copy them over each other and mask out to your prefered balance. You can then treat each layer seperatly and after masking even re-export sections if you destroy the levels too much.

Its messy as hell, but with a bit of practice can get some amazing results.

After watching Leles tutorials i am now a LWF and phys-cam convert.
Didnt think this would happen but i can get so much nice light into my interiors without faking.
But i do not darken my materials since this seems to stop the bounced light too early even if its physically correct (at least in my interior tests).
