Hello I agree, I also use my personal camera profiles in my raw converters. The camera profile is used to obtain the most faithful colours possible right from the development phase, which makes the work much easier right through to retouching. It's essential for the professional photographer and even more so for reproduction. It is unthinkable for a museum catalogue to show differences in colourimetry from the originals!

Hello I'm just following up on the first post with the screen copy, which is interesting! Firstly, yes, it already appeared in the very first versions of Photo and the developers removed it.😒 At the time, I made the same request as in my post above, i.e. sorting on the device class of the profile. Why? To avoid having 2 pages of useless profiles in the box. You can see on the screenshot that the user has set the camera profile to sRGB! I used to be a colourimetry trainer and I spent hours, including on forums, explaining the difference between a matrix space and a device profile. To use a joke, most of the time it goes in one ear and out the other without encountering any resistance ... ☹️ A camera profile contains the luts needed to characterise the sensor's defects, which a matrix workspace, even a 32-bit floating-point workspace, can't replace. So yes, even if it's already been asked for a long time, it would be nice for those who know how to use them to be able to choose the camera profile in the develop persona. NB. The Spyderchecker only works with Lightroom or Camera raw. It does not generate a profile, either icc or dng, but acts directly on the sliders below it (hue, saturation, etc.).

Hello everyone Agreed, that's what I mentioned in this post, without much success as you can see. https://forum.affinity.serif.com/index.php?/topic/197739-photo-develop-persona-input-profile/

Hello, In the develop persona, only the output profile can be positioned. An input profile is desirable to improve the quality of the development depending on the camera used. This would be to display the icc (and icm) profiles in a drop-down box. To avoid a list that is too long, it's possible to display only profiles whose device class is "scnr", which will eliminate display profiles, spaces and printing profiles.

Hi and thanks a lot! I am looking forward to this!

Hi, I totally agree! Windows users are not like Apple users, they need to see under the hood and the "WindowsApps" folder is not accessible even as an admin. My few useful programs are accessible by shortcuts and there, it's impossible. I also ask for the return of ".exe" files

Hi, just for information this is my current driver updated by Windows. Hope your PC works fine.

HI, OpenCL works well on my W10 laptop wih HD 620. Photo 1.9.4.1065.

Hi, By default, Windows uses sRGB. For the solution, it's sufficient that the user has the choice of the profile to be assigned exactly as in PS when the right box is checked.

Hi, That's the basic problem! Why assume that the original space is sRGB?! Ok, we have to start from something, but it is better to leave this choice to the user! A drop-down box is not so difficult to code, it has been done elsewhere without difficulty.

In fact, Photo seems to first make a presumably sRGB assignment and depending on the choice made in the preferences, displays it as is or converts it in the workspace. In the case of an image defined in ProPhoto RGB for example, you can easily imagine the damage! The cleanest solution would be to let the user make the assignment of his choice instead of making an arbitrary one that has little chance of being the right one.

No one has said otherwise and that is not the question. The user can see what is happening and the developer knows what he has written. ___________________________________________________________________________________________________________________________________________________ You don't seem to understand the problem. Converting an image from one color space to another is done by matrix translation of the RGB values of each pixel. Without the knowledge of the source color space, you can't calculate the correct values in the target space. It's as simple as that. AF Photo can only assume that the image is defined in an arbitrary space, a priori the sRGB, and then performs its calculation which can only generate errors and a degraded image if the starting color space is different and more wide than sRGB. It would be better if Photo offered the user a wider choice, one of which would be to assign the space of his choice before opening the image (like Photoshop). Usually this choice does not have to be the workspace but the space in which the image was originally created. This is where the result of the conversion will be good.

My questions are primarily addressed to developers ...

Hi, the problem address images without an embedded profile opened in Photo. - By default, the image is displayed in Photo as being in sRGB. But is this an assignment or a conversion? If it's a conversion, what is it based on, since we don't know what colorspace it was created in? - If the "Convert open files into workspace" box is checked, Photo displays the image as being in the workspace defined in the preferences and displays the warning message. But again, is this a real conversion or a profile assignment? If it's a conversion, the problem is the same: what is it based on, since we still don't know which colorspace the image was created in? It would be good if in this case of an image without a profile, Photo asked the user what to do and left the choice of the space to be applied to avoid conversion mistakes. Photo 1.9.2.1035

hello everyone, my wishlist is short: be able to pass the image in Lab mode as in PS with the possibility to hide layers a and b.
