.... - might be nice to do some kind of filmic rolloff in post if you've got it all 32 bit?

Don't want to hijack this thread but I'm curious about your "filmic rolloff in post"... Plz, what do you mean ?

With cameras, exposure isn't normally totally linear and where an image goes into the overexposed areas it'll burn out a little bit more softly. If you were to take a graph between black and white it'd look like this rather than being a straight line between the two:



Using someone else's photo as an example, you can use tonemapping such as reinhard in vray or just a simple curves in photoshop to take some of the burnt out areas near white and gradually bring them back down - the idea is to leave your mids and darks the same but only bring down the very burnt out highlights a bit. Ideally I'd render out from vray in normal linear so you can do as much with render layers as possible but then do a bit of tonemapping on your final image. What the intention is would be to take something like the below image - leave most of it the same but just take away some of the harshness of the really burnt areas:



Whatever about the saturation being lost in the above example, the important bit for me is that the lampshades over the kitchen island change from being a block of white pixels to having some softer detail in there. It's a similar case in the light bricks of bobby's render - there's no real detail in them at the minute.

I can't keep it 32 bit, because some things in post wont work. Plus, I can't save as a jpeg unless I go to 16 bit.

Ctrl+N
(set colour mode to 16 or 8 bit)

WOoooh !! I did not expect so many explanations !! thanks.
Ok, I already knew all those notions of tone mapping, in fact, I was more intrigued by the "filmic rolloff" term in fact....
Anyway, it's always good to read your explanations. Thanks again joconnell!

[joconnell]

Yep sorry - filmic = logarithmic curve for your brightness = exponential or reinhard colour mapping in vray or that type of soft rolloff curve in post.

Alright ! I learned something today
Thx

Interesting project. The original architect sold the project to a developer and the developer ended up buying more land around the original site. The first project only showed the front, so that was the only thing modeled. I didn't have plans for anything but the front original, so everything else I had to make up. Anyway, here are some new image, for the new development.



Generally, I don't have so much shadow, but I wanted the front of the buildings in light, which is the only interesting part. The shadows hopefully hide the boring large brick walls.

wow! amazing work

[glorybound]

Well, I wouldn't say that, but they turned out good. I sent them off to the owner today, Usually, with this client, there is always changes

Here's a tip I do, put the 32bit render in a 32bit PS document and then do a clamp with something like arion fx for Photoshop or camera raw tools / native ps tools or whatever you like. Save that.

Then do a new 16bit document in photoshop and reference/link the 32bit into that parent document. It's totally non destructive this way as you can always adjust the 32bit and work with regular PS tools in the 16bit master document as it is just references.

can you explain more about the clamping part and referencing, i am also really interested in this workflow
