Need help with post production.

Hello ...

[Alexandre SCELLIER]

Hi,
This is the way i fastly postpro my renders when I do not use Render Elements :

In Corona :
- in the Corona FrameBuffer / ColorMap, choose the correct Exposure (EV)
- set the Highlight compress to 1 - the image should look a bit burnt but you'll be able to fix this in Photoshop ...
- Save your render in .exr 32bit-full float

In Photoshop :
- I use a plugin to correct the burnt areas (tonemapping) - ArionFX Tonemapping from RandomControl. With this one, you'll be able to add bloom, glare and so to your image, making it more attractive ...
- This done, your image should look like in the Corona Frame Buffer (when you use higher Highlight compress values), but keeps more lighting datas (like a RAW image!)...
- Then use Camera Raw filter. You'll access to a lot of parameters (Contrast, Exposure, Blacks, Whites, Midtones ...) just play with them!
- You can adjust the final look with Curves, Photo filters ...

It's a very fast way (15-30min) to improve the look of your images.

An example :
Straight out the Corona Frame Buffer :


After postpro :


Sorry for my English and good luck!

Thanks

[danielmn]

Ill have to try this thanks for the post.

[Noah45]

Also, thanks

I'm straight outta Corona using VFB+. But we are missing the glare.

Following your tut, to eliminate manual placement of glares, through PS

[denisgo22]

Why to Use RandomControl if possible to change Highlights/Contrast/Tone directly in Corona VFB???so at least you can see what you render   correctly///
And others effects: Glares,Bloom and etc. stuff  with Camera Raw, Knoll,Alien Skin Exposure and many,many others in PS////
And one more interesting question...As you remove the artifacts on Alphas edges in 32 EXR  images??? with PS Matting this not work perfectly???

[Noah45]

Quick control, VFB+ seems best, just missing glare, subtle but :K

[denisgo22]

VFB+ terribly brakes with high resolution images///
With resolution more 1200px it is generally better not to use it...

[Noah45]

Just screen here for my renders, but why does it break down @ HR?

[denisgo22]

brakes in VFB+   ---  This means that the change in each item comes with a delay of 4-8 seconds with resolution 4k, for example///

[Juraj]

I have no such issue, even at 8k and higher.

Of course, as by default, I don't keep updated DOF or glares, which are both heavy for rendering time. Also, I keep update time to something reasonable, like 5000ms.

[denisgo22]

Well, then why do we need it, if the same can be done in the ordinary VFB from Corona in general without any delay....

You don't need it, and no one in this thread mentioned you need it, thus I almost perceive your message as trolling attempt in disguise.

But why do I or the poster above use it ? Because all the tools that you don't have in Corona buffer but also don't need to wait for PS.
Just because it doesn't update "real-time" DOF in instant at high-res doesn't mean it's useless. Frischluft is not real-time either.

Basic stuff like Highlight compression, exposure, and contrast give me zero delay in real-time regardless of resolution.

But additionally LUT support, further correction tools (much better white balance), filmic tone-mapping, histogram, comparative history buffer, etc... yeah, the same as Corona buffer I would say.

[denisgo22]

You Don"t use PS after all games with VBF+???!!
You save the image directly from VFB+ to the final version of  render???!!!
I can't believe!!
And if you use, all these stuff  with more convenient faster and more flexible settings
and masks,to do in PS, it is clear to everyone////
PS- And what will you do, if some
 stupid customer, suddenly asked to remove a nice glare on light bulbs?

[Juraj]

I can't believe!!

I never said nor implied anything like that anywhere... I suggest better reading comprehension and not making stuff up.

it is clear to everyone////

Ok !! ?? !!

!!!!!

Hej Juraj,

dont waste any energy in this guy..
He was bannend before under another user profile
and is just trolling around here.

So for me: +1 on him to get banned again.

Best regards
Nico

[denisgo22]

No one time wasn"t banned///
because of what it?
I express my opinion
different from other's?

or all should use
unnecessary bells and whistles?

[romullus]

Calm down guys. Don't throw false accusations at each other. The only on that was banned from this topic, was OP and i believe that denisgo22 has nothing to do with him.

[burnin]

Lamps have same intensity as candles? First you need to balance lighting.
Here's a quickie (1 click to raw version) - with custom preset on 'Real Camera' software (still my favorite post pro tool):


My advise to readers, take this practice with a grain of salt.

[denisgo22]

Thanks to Romulus, for an end point to this debate,
And i am sorry for my pressure...
I have a question to the continuation of this theme.
Maybe somebody knows a good way
remove artifacts from Alphas edges on 32bit exr images???
Matting in PS, AE, Nuke don't give a perfectly results...

[burnin]

Maybe check at 10:45

[Ondra]

[starart]

banned again. This is getting sad.

Really? for what?

Hey Ondra ... I suggest you to do cleanup the website users database !! ;)

[Ondra]

Seriously... you have nothing better to do? That is just sad...

Hey mate,
I must assume i made a mistake using the same CoronaLightMaterial (4500 K + 500 intensity) for both lamps around the bed and candles ... It results in a too powerful glare in those candles ... whatever, the client seamed satisfied :D ... Would you like me to share the 32bit-exr file to play with it a bit ; so you can share with us your postpro tips ? :)
I'm always interesting in news ways & tools to improve my worflow!
Regards.

Hello ...

Buddy,
Could you edit your post title ("help postpro" was good enought ; why did you change it?) and your first post, so more people will be able to access this thread conveniently :)
Thx

[romullus]

This chap is banned for a good reason, so he won't be able to fulfill your request. However this topic turned out to be pretty useful (what a disaster for a troll that started it :]), so i'll change its title.
