Event Overview
Join Cinematographer Alister Chapman as he explores the often confusing world of gamma curves in this interactive webinar.
We have all heard the term gamma but what does it really mean? How does it affect what we actually capture and how does gamma effect the way an image looks on a screen? As more and more TV’s start to support more than one gamma it’s going to become important to understand which gamma you need to use for your content capture, archive and delivery?

We are running a 90 minute session starting at 11:00. This will be an interactive webinar and questions will be welcome at anytime.
 
Alister will look at what a gamma curve is, why we need them and what they do. Looking at different capture gammas such as Rec-709, Hyper-gamma and S-log Alister will look at the differences between each, trying to get past the techno-babble so that you will understand which to use for different applications and how they effect the picture information you are recording. What is “the knee” what is a shoulder, toe and roll-off and why might we need them? Which gammas have them and which do not? Why are some gammas better exposed brightly while others work better exposed a bit darker? What happens if we record without using a gamma curve as happens when shooting linear raw? All these questions will be answered in the first half.
 
In the second half Alister will look at how different display gammas effect the way images look on a TV or monitor. As HDR becomes common place it is going to become very important to understand the differences between Rec-709, S-log ST2084 and HLG (Hybrid log gamma). How do you convert from one gamma to another in post production and how do different gamma curves behave in post production? As modern and future TV’s start to support more than one gamma it’s going to become important to understand which gamma you need to use for your content archive and delivery. Should you continue to use Rec-709 for your programme masters or should you consider other options such as HLG, ST2084 or perhaps even S-Log3? Who should attend:
This webinar is suitable for anyone who is interested in discovering how to use gamma from capture, archive and delivery. It is particularly relevant to people who are thinking of renting or buying a camera for video production. Filmmakers, Cinematographers, DoP's, camera operators, freelancers, Producers, Directors.
 
This event is a must for anyone interested in gamma from capture, archive and delivery
 
Register now, even if you can’t make it we’ll send you the recording.
