Thanks to everybody for the compliments. More tutorials to come very soon!
There is something inherently sexy - for the nerd/geek minded at least - about listening to a female voice speaking all that jargon.
Nerd/geek women will probably think otherwise (we have a few ones), but as I told you some time ago, PixInsight is definitely a sexy application
I think you used this voice: http://www.golocalise.com/en/our-voices/english-us/kim
You're quite close, but no, she isn't Kim
part1, around 2:30: "linear images have too much contrast to display on the screen". Really? I thought it was too much dynamic range. If anything the image lacks contrast.
As long as no clippings occur, the dynamic range of the data is the same, irrespective of whether they are linear or nonlinear. It is the distribution of the data throughout the available numeric range what changes. In the case of a linear deep-sky image, almost all of the data are usually distributed within a very narrow peak close to the shadows region of the histogram. This leads to extreme differences that make it impossible to represent the image on nonlinear display devices. For example, there are no midtones at all in a DS linear image. Another consequence of the linear distribution is that we can have very high differences between adjacent pixels. For example, you can see two neighbor pixels with values of 0.2 and 0.05 on a star.
