I know this has been requested several times... One earlier post for this dates to 2018! But it's not yet been added to Affinity Photo. 

But what if I told you, Affinity Photo used to have this basic feature of raw development? You can even see it in this video tutorial! (Screenshot below). Is there any chance this feature can be added back to affinity? Pretttty please? 😁 I wonder why it was removed in the first place. Anyone remember if there was something wrong with it?

I truly believe  RAW development  should be merely  exposure range  choosing to clip and all .    Or not to clip straight to 32 bit file .  Never understood why people  tweak colors in RAW.   It's so much more convenient in the soft itself with adjustment layers.

You have LUT adjustment layer where you can make your own camera/ illumination or whatever specific correcting  preset .      Aphoto have a great  advantage over Photoshop with LUT  building tool  from original and target  image pair .    Works for me  with color charts images as a home made camera "profile".

Technically speaking the only raw color changes done are the white balance multipliers, after that, the image is demosaiced and it's a 16 or 32 bit image (depending on the raw developer) held in memory or as a temp file on the hard disk that the adjustments in a raw developer operate on.  Camera color profiles are ICC or DNG profiles applied to that demosaiced image. No reason it can't be a LUT file so long as the values in that LUT are suited to the color space the image is in. The advantage of using ICC profiles is that the values are stored as Lab or XYZ (or can also be a simple matrix profile). It's possible to convert an ICC lut to a .cube lut (or whatever lut format) so long as the software you apply it with accepts values below zero and above one. I'm not sure how affinity handles that, might be interesting to go check later.

Nevertheless the point is, despite your personal preference, a great many people expect this feature in a raw converter. The forum is full of people who have asked for this to be (re)implemented so it meets the majority of people's minimum expectations for a raw developer , but the Affinity Photo programmers seem to be consistently silent on this. I don't know why, all they really need to do is incorporate lcms2 into their code to do it. Shouldn't be very difficult for a programmer

Not sure how that happened considering I hadn't copied the URL for the post that was not yet submitted, but I fixed it.

I am not against it actually.      It just requires a special soft to profile your camera.  hours of manuals reading , hours to figure out how icc profiles works  and what they are  so you wouldn't  set a camera profile as your system one.

While this LUT building approach   from original picture and another picture  with color chart values  set by books   as a target    seems  amazingly simple to do  and moreover to  understand .   I just  adore a simple solution for a complex problem.         But  I don;t know  really how precise it  is   vs  ICC profile

I'm not sure what approach you learned for building ICC profiles, but there are a few easy methods.  There's  Lumariver Profile editor (although the basic version only does DCP profiles) , and if you buy x-rites brand of color checker it comes with software to make ICC or DNG profiles. the QP card 202/203 also has software for ICC, though if you encounter any issues with their software (which hasn't been updated in a while) they don't respond to email at all so I'd shy away from QPcards. I suspect the company behind them is defunct. The SpyderChecker brand one I think also comes with software. Basically all you do is take a picture of your color chart, feed it the raw file or tiff, and it gives you a profile. 

I hope that helps if you ever revisit them, but if you're happy with your current workflow, nothing wrong with that either!

I had Xright  checker  once and  then misplaced it somewhere.   From what I remember it still had been a learning curve.  Starting from basics what ICC profiles are. 

Recently I bought a cheap $15 color checker, no software  and it somehow works  with LUT layer  right away.  You make a picture of it , then edit color charts to colors values it  should be  and use it as a target second image during  LUT building.        But again I have no idea how precise it actually is.   

Perhaps less precise but still looks enough to extract albedo diffuse  color  from something in blue late afternoon  shade  for example , A reason I use the checker for..

I am not saying an ICC solution is redundant , I just found this workaround and it seems very simple an cost effective

Thanks for sharing the knowledge. It's always good to know more than one way to do things.
