Video: The Beginners Explanation of Gamma Correction & Linea

[matt gorner]

I've done a video tutorial on the very _basics_ of what gamma correction and linear workflow is, and why you need to use it, especially if you're lighting interiors.

I realise there are many threads and tutorials on the subject, but none of them explained to me what gamma is, and why it exists anyway!

This is my take on the explanation.

PLEASE bear in mind this is meant to be _very_ simplistic, and almost certainly leaves out certain topics or concepts. It is designed to help those, like me, who have heard about it, wanted to use it, but were put off by the technical aspects of it.

I just hope enough of my understanding on this is correct to be useful!

Cheers
Matt

Thanks for the info
Nice for begginers to understand this

Thank you Matt! very simple and understandable!
The next step could be: How do we do it in Lightwave and show the tools allowing us to change textures, render.
Btw, how do you make fades between images in pdf???

You need Acrobot (not Acrobat Reader) then just select all the thumbnails in the Page view display, right click, and choose 'Page Transitions ...'

And yes, I plan to do a lighting tutorial (but nothing to the standard that Mr. Quick can do!) But should complement this video nicely.

Big thanks Matt. It's nice to have you on the Kray forums.

Nice tut Matt! Now add an overview how easy it is to use Kray QLWF plugin to do the adjustments automtaicaly.

Hehe! Yes.

I still want to do my 'overview' video of Kray, not a tutorial, more an advert really.

Fantastic - thanks a lot Matt! I didn't really understand this until your explanation.
Beautiful presentation as usual!

Of coarse LWF Gamma is only correction for colours and textures (and tonemaping too) personaly I thing LWF gamma as tonemaping is good but renders looks "flat". We tests still reinhard blending in Kray (blending between LWF gamma,LWF exponential, LWF Linear looks very promise: in blending we can get best things from gamma , exponential or Linear and add LWF for all). I hope G. will add curve too (silimar in PS, becouse bright colours need increse, dark decrese in tonemapping).
