  1. Hello there, I had a quick try and it to me the the previously broken LUT Export is fixed in release 1.7 - can someone confirm this (or am I victim of a placebo effect)? Best wishes Jurgen
  2. sigh... thanks. I am not aware of the bug log, will look for it
  3. Hello there, here on the forum it was confirmed that LUT export was broken in Affinity Photo 1.6.6 - before I attempt the frustrating exercise to try it out has it been fixed for release 1.6.7? Thank you very much, Jurgen
  4. Thank you very much - I will do en-disable settings as you say and look at the results. Thanks again for your time and effort!
  5. Wow smart lighting is NOT on - that's why I copy-pasted the entire corrections.
  6. Thank you for your explanations, it makes sense. However how does this explain the appearance of noise when adjusting the luminosity? Explanations put aside, the display and handling of a raw file by Affinity Photo is _objectively_ erratic, as I said, I exposed at -0.7 stops. The reading in Affinity Photo and the resulting necessary corrections are based on a photo underexposed by (I estimate) 5-6 stops.
  7. Hi Gabe, sure, this is raw file directly from my camera's SD card, a large file of course. I hope this helps! Best wishes. A7_04530.ARW
  8. Oops it took me more than 2 minutes to write so I didn't see yours :-) Now the Affinity guys have 2 reasons to take this seriously. Did you post histogram shots as well? They need to see...
  9. Hello, I noticed with the previous release of Affinity photo an extremely low level of luminosity values in raw files and I reported it here - as for Release 1.6.7 it was announced that raw processing had been reviewed I was hoping that the situation had improved but it hasn't. Attached are 2 screenshots, one from Affinity photo and a second from another raw processing application. The exposure reading of the camera for this photo was -0.7, I purposely underexposed slightly. As you can see all automatic application of s-curves etc was switched off in both applications. The other app reads the exposure value correctly whereas Affinity Photo still displays a histogram that is underexposed by several stops. This is not an academic issue, in order to make that image publishable I would need to boost exposure by a large number of stops which would introduce a lot of noise which when using the other raw processing app would not be necessary. It would be great if you can look into this seriously. I do not think that the issue is with my camera (Sony A7 R II). I love your application a lot so I want to use it for the entire process and not develop raw files in a different app and then reload the tif images into Affinity Photo for further correction.
  10. Thanks for the explanation. When I change the RAW engine to the other one (Apple raw) there is indeed a significant difference - still I'm not entirely happy, even with Apple raw i'm well over one stop too low. I set my Sony camera to compressed raw, you may have heard of an issue in the Sony A7RII where Sony's raw compression creates artefacts. For this industrial project I didn't care to much so I did not use the uncompressed raw format because the file size is 4 times larger or so. Could this have an additional influence?
  11. Hi there, I had my first professional project that I wanted to edit etc with Affinity Photo. I exposed in my camera Sony A7RII all photos with an average of -.03 to -.07 with a close look on highlights (zebra display). - To my big dismay ALL shots appear massively underexposed in Affinity photo, the large majority of the images required a 2 stops exposure gain, the white balance was _totally_ off. So after spending a frustrating long evening on it. After seeing the impossible results this morning I quickly returned to the photo application that I used before, DxO Optics Pro. And there the images look ok, the colors look correct ands the expose is slightly under as expected. Was is happening? From the online tutorials for Affinity photo I disabled all "automatic" corrections for raw files, I do exactly the same in DxO by the way. As an illustration I attach 2 screenshots of the same image opened in the software, one Affinity Photo the other in DxO Optics. Any help would be largely appreciated! Best regards Jurgen
  12. Now isn't that a complete list... Thanks a lot! I was fixed on the video tutorials.
  13. In the tutorial "Macros: Equations" there is mention of different noise algorithms available in the equations - I would be glad if these (and everything else possible with equations) could be subject to a tutorial or online paper sometime. :-)
  14. Hello there, in the tutorials equations are mentioned a few times, like in the Macros videos. But there is no general overview of the functions that I am aware of - for instance, relative to noise the video mentions that there are 4 different noise generators but I didn't find specific explanations as to possibilities using equations. Is there anything? I'd be glad to go through it...
