[darktable-user] Error in an angle, in The Book
Hi list. New user here, just read the Fornari, Latronico, and Manea's "Digital photo development with darktable". (see: https://www.darktable.org/resources/) I guess it is a good read for both novices and not-so-novice but new to darktable, like me. Thank you! And let me try to thank further with a small correction. There is a mathematical error on the text at page 72. It reads: «Being the line [...] with slope of 45°[...] in the right portion of the figure [...] the slope is reduced to 22.5°» The first line has a height of 1 for a base of 1, it's angle is 45º. But the second line has half the height, i.e. 0.5, which results in a angle that is not half of the initial one. Instead the angle is approximately 26.6º - computed from atan(0.5/1), or atan2(0.5,1), or similar depending on your calculator. (To be pedantic, it probably shouldn't be "slope", as that is the ratio from height to base - but for a non mathematical text that is a very very minor issue :-) (See: https://en.wikipedia.org/wiki/Slope) BTW, the heading at page 74 misses a 's' at "the *s*plit tone plugin" again, thank you I hope darktable is maintained for a long time (I am changing from another that stopped being updated) as it looks promising just what I needed.

[darktable-user] Vibrance in darktable
Hi, According to the darktable manual, "Vibrance saturates and brings down the lightness of the most saturated pixels to make the colors more vivid." Should it not saturate and bring down the lightness of the least saturated pixels? Paul. darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org

[darktable-user] Installation Mac OS 10.13.6
Hallo, I´am using Darktable on a iMac Version OS 10.13.6. Since today I had no problems for a couple of weeks. Today suddenly I can not start Darktable any more. I uninstalled and made an new installation. But I always have the same problem. I guess it is a problem about the „Programm from a not Apple-Store“ source. I tried what you say on your page: „...or you can prevent this from happening by running xattr -d com.apple.quarantine ~/Downloads/darktable*.dmgcommand before mounting the image (or xattr -dr com.apple.quarantine /Applications/darktable.appafter installing)…“ I tried this, nothing happened. What can I do? I am a photographer, not a computer expert. Can you bring „Darktable“ to the Apple AppStore? This would be the easiest solution for the „simple user“ like me. Thank you for your great program - I would like to install it! Sincerely yours, Patrick darktable user mailing list to unsubscribe send a mail to darktable-user+unsubscr...@lists.darktable.org
