Re: [hugin-ptx] New release for mac?

[dgjohnston]

After telling MacOS that everything was okay (and setting Full Disk Access) 
everything is now working on my MacBook Pro
 15-inch, Mid 2012) running Catalina 10.15.7, Intel Core i7 16GB 
memory, Intel HD Graphics 4000 1536 MB.

So you can caulk this up as a great success.

Thanks for putting this together for us Mac users!

 Hi Bob … I have a MacBook Pro (15-inch, Mid 2012) running Catalina

 If you need some additional testing of you build I would be willing to 
 test it for you.

[hugin-ptx] Re: Camera response curve calibration (gamma)

[mkogoj...@gmail.com]

Alright, I am happy there is a graph function in Hugin, thank you... but 
now this last message makes more sense, which I am not jubilant about. 
Allow me to explain -

I want to check if the photo stacks I am working with are linear or not.
Yes; raw files are supposed to be linear, but Hugin does not work with CR2, 
only tiff. If I convert the cr2 to tiff it will probably add a gamma curve, 
but I don't know if and how, and so I wish to check the result. If nothing 
else my camera's sensor might be doing something funky as well.
But if I can choose the type of image I have, then am I telling Hugin to 
(or not to) calculate the curve when stitching instead of only calculating 
the curve and returning the result.

In the attached picture green shift is seen in the cloud. To my knowledge 
this means that the gamma curve has been calculated badly. I wish to know 
what kind of a gamma curve images have after I converted them from raw.
pasteall.org/pic/3b53b009a65c4ba19d02dab9b458fb4a 

"For extracting the true camera response curve there are other algorithms 
which are better suited."
Leaving aside that I don't know how to plug algorithms into Hugin, do you 
have any suggestions? I got HDRShop on academic license (which is supposed 
to be able to show you the calibrated response curve), but it either tells 
me 12 photos are not enough or it simply crashes when trying to generate 
the curve.
