Not sure I really like Dominic's paraphrasing of my replies to him... But, in essence he is right.
We (the Light Illusion team) are not fans of the old school gamma graphs.
The DifGamma graph plots the measured gamma vs the target gamma, which is exactly the required info - is it not?
As can be seen in this image, the measured gamma is the delta from the target.
(This is actually a BT1886 gamma targeted to a power law 2.4 gamma, on a display with a raised black. See: https://www.lightillusion.com/error.html#bt1886_gamma
I've added in the values so you can see how the graph reads.
If the plotted line overlaps the target line totally it would be exactly the target gamma.
(The target gamma is set by the selected colour space.)
Now, having said that, LightSpace was never intended to be used in the Home Cinema market. Never!
It was thanks to Buzz and Ted that we are here at all...
(Yes, feel free to blame them for everything!)
The whole focus for LightSpace was professional colourists and colour management use in the film & TV industry.
(I am/was a colourist, and developed LightSpace for my own use, as nothing else was available that did what I needed.)
LightSpace is also over 12 years old!
(The first release was Feb 2007, although the first program the could be defined as the start for LightSpace was in 2005!)
What all this means is there are limits as to what LightSpace can be be coaxed into doing some 12 years later...
By comparison, ColourSpace is a baby, with years of growth ahead of it.
The initial release will be limited, because we have to start somewhere.
Those limits are just to enable us to define the start point.
Moving forward we will take ColourSpace to place LightSpace just never could go.
And this time we have developed ColourSpace with the Home Cinema market in mind, as well as our core Film & TV industry.
(We have also been working with some major display manufacturers to make sure ColourSpace has the flexibility they need for display assessment, as well as the likes of Eurofins, and Bureau Veritas - testing companies that define assessment programs to ensure TVs meet minimum standards.)
So with a ground-up development of a totally new product we are free to go where we want, and add whatever tools we want. And Home Cinema will be a big part of this.
A select few (in all our different market industries) have known about the existence of ColourSpace for some years.
(Originally code-named BluePlanet... you can work that out for yourselves!)
And they have been helping make sure the underlying code-base is flexible enough that we do not code ourselves into a corner, as with LightSpace.
(Seriously, LightSpace was never intended to become 12 years old, and was never intended to be used as it is now!)
So, to get back to the original question/point, while we are not fans of the traditional gamma graphs, they will almost certainly find their way into ColourSpace, as there really is no point not having them.
And we will also be adding bar graphs.
And multiple graph layouts.
As well as many more really kool capabilities related to profile data assessment and even manipulation.
This time, the LUT side of ColourSpace in not the real focus, as it is within LightSpace - as that was always what it was developed for. For ColourSpace the focus is more on the profile data, and what can be done with it.
But! Do not expect to see all this in the fist release.
The first release is a baby, and will hardly be crawling, let alone walking!
As we progress with ColourSpace will be happy to hear thoughts and ideas, but not here.
We have our own forums on our website, and as everyone knows I tend to respond quickly to emails.
(But, I will not be responding repeatedly to questions I have already answered.)
The last point is to say that there has not been a recent update release of LightSpace as we have had to make some major core changes to provide as much backwards compatibility with ColourSpace development as possible.
We do not intend to force anyone to swap to ColourSpace, and in all honesty with the first few ColourSpace releases I would suggest that existing LightSpace users would probably be better off staying with LightSpace.
But, that will change as ColourSpace grows.
