Hi, unfortunately, the plugins nik have become inoperative in version 1.6 despite their good statement in the prefs.

Hi Lee D, Yes, I'm talking about camera profiles, "input profile" is a generic term. I know this has been removed and I consider this like a mistake in color management: opening a raw in a matrix space does not allow to take into account the colorimetric characteristics of the camera as its profile alone can do. It does not seem very difficult, it is an option of DCRaw, like other converters, and it is enough to list the profiles present on the machine that have a device class "scnr" and only them (icc and icm profiles of course).

Hello, Camera profile is a feature that has been omitted over the versions and is very regrettable !

Hi Thanks a lot for this ! This version for windows does not know the worries that I have with the Mac version ... It only miss the input profiles in the develop persona, are you considering reintroducing this function?

Hi Andy, Yes, it's a very good thing to have changed like that. For non-linear colorspace, I will be globally ok for the ProPhoto gamut, but not for its TRC (1.8!). However, its gamut may seem limited in some cases such as art reproduction where the Hasselblad profile proves beneficial (there are others even larger with all their virtual primaries). Now, it just lacks the input profiles. As you probably know, the apn profile characterizes the colorimetric response of the sensor and the associated electronic, which can not be done by a color space that is a matrix reference system. I think I remembered that originally Affinity Photo for Mac, these profiles were present but the input profiles (device class "scnr") was never listed and in this case, it was useless. Regards

Hi James Ritson. Thank you very much, here is finally useful information! Can I get information about this unbounded space? Are you planning to introduce input profiles in the develop persona? The input profile characterizes the defects of the device while a space is a purely matrix system. The information is still displayed during the development phase in the persona photo (my screenshot above). (Sorry for my questions but colorimetry and color management are my job).

No, sorry but you do not see the problem. Opening the image in sRGB eliminates a large amount of color shades due to the very small gamut of this colorspace. Changing the colorspace in the "Profiles" box will never cause them to return. They are definitely lost. Hence the need to open the image in a larger colorspace and it's what the preferences are used. I repeat myself, but that's what the input profiles (camera profiles) serve.

Hi Chris_K It's exactly the same thing with the beta 44-RC than this post on the Mac forum : https://forum.affinity.serif.com/index.php?/topic/30115-32-bit-profile-is-ignored-in-develop-persona-rc2/?p=148809 32 bit profile in the preferences is still not applied at the openning of a raw picture ... sRGB is always applied and it's wrong !

This image is correctly openned in the photo persona with the last RC5.

Hi Chris_K. The problem is still present in RC5. To open a raw in the small sRGB is to truncate many shades of colors. And then moving it to the photo persona with a larger space is strictly for nothing: the lost shades will always be. It is always necessary to open a raw in a colorspace as large as possible, the ideal being to use the camera profile as profile input, unfortunately absent since the origin of the program. http://laurentiaart.com/WP3/wp-content/uploads/2016/12/Capture-d’écran-2016-12-06-à-14.13.32.png

Hi Chris_K, my answer is the same for my Mac.

Hi Wernich, is your monitor a wide gamut ? Your color settings in Windows are not correct. In the box "Viewing conditions profile", you have to use "Profil WCS pour les conditions d'affichage ICC" (sorry, my OS is in French) like you can see here http://translate.google.com/translate?hl=en&sl=auto&tl=en&u=http%3A%2F%2Flaurentiaart.com%2FWP3%2F2011%2F04%2Flagestiondescouleursetlesdifferentswindows%2F (this is a rought Google traduction from French). You should never put a color space in monitor profile! A color space can not reproduce the characteristics of color reproduction of your screen!

Hi Chris_K The 32 bit profile is positioned in the preferences before loading the image. The Hasselblad profile is an example (even if I use it ;-) ), the problem is the same with other profiles.

Yes, it is a problem ... Affinity photo appears to display the image in a larger colorspace than the one in which the image was created (in develop persona ?). The color management seems to be perfectible

Hi, the 32 bit profile is ignored in develop persona (RC2) :

Hi, the 32 bit profile is remembered well (thanks) but it still ignored in beta 42 : Also, Affinity Photo beta 42 crashes when I call the preferences shortcut in develop persona : Win10-1607 home 64 bits.

Hi, Portrait Pro 15.6 crashes on Mac with the RC1 during the face recognization (memory problem ?), but works fine on Windows with beta39.

Me too ... However, it does not happen on Mac where the cancellation of the development closes the image (1.5 RC1).

Hi, the 32-bit profile specified in the preferences is still overwritten by the default sRGB at each relaunch. This problem does not appear in the RC1 version for Mac (see the screencopy) Before, with a custom profil : After the next launch, with the default sRGB :

Hi. The 32-bit profile in the preferences appears to be ignored, or the indication "RGBA / 32 (HDR) is inaccurate (1.5 RC1).

That is not quite right. A raw image is not indefinite, it is delimited by the capacities of the sensor. And this sensor must be profiled. This is precisely what is missing here in the management of colors: the profile of camera! The choice made in the "Profile" box is more that of the color workspace. But the camera profile that characterizes the apn is cruelly missing. Moreover, with regard to the default application of the sRGB, the preferences are precisely there for that. In a good color management, one must distinguish three things: the camera profile, the color workspace and the output profile.

Hi, it seems to be a problem with this beta of Photo. All filters of Nik Collection work fine with a 16 bits image. Its correct with the mac beta 1.5.0.10 and under Windows, its correct with other bitmap editors like Photoshop CS6. ColorEfex with the Mac beta version.

Hi, Ok for the raw size. But, there is a problem with the 32bitsRGB Colour Space. At the loading of an image, the custom setting in the preferences is ignored and the default sRG is apply. Furthermore, the custom setting of this colorspace disappear after relaunch.

Hi Jon, Thanks a lot !

Hi, This issue still persist since the begin. After each restart, the user colour settings in preference are overwrited by the default setting. (https://forum.affinity.serif.com/index.php?/topic/21537-affinity-designer-on-windows-1504/?p=102581)
