  1. I'm disappointed to see this wasn't addressed in Affinity Photo 1.7. It's still absolutely baffling to me that this isn't an extremely urgent issue for Serif and other Affinity Photo users. How on earth are people using Affinity Photo for raw photo editing with a histogram that's been broken for so long? Why doesn't Serif address this? This bug was the primary reason I gave up on Affinity Photo and reluctantly bought a Lightroom subscription, but I would prefer to return to Affinity if it was ever fixed.
  2. I posted about this here but didn't get an official response so figured I should report it as a bug directly. When I open a CR2 raw file, the histogram appears "squished" to the left side with a bunch of seemingly unused space on the right side. If I click the develop button to move into the photo persona (without making any changes to the image at all), the histogram is more evenly distributed in a way that matches what I expect. I've tried with the develop assistant set to both 16 and 32 bit modes and the results are the same. This happens only in the desktop version of Affinity Photo (I'm using version 1.6.7 on macOS 10.14). The histogram in develop mode behaves as I would expect in the latest iPad version. The develop persona is essentially useless because of this issue, to the point that I'm having to do my raw development on the iPad even when I'd prefer to use the desktop. Attached are example histograms from the develop and photo personas, following the flow I described in my second paragraph.
  3. Thank you—I'd seen that thread too but wasn't sure it was the same issue I was experiencing. I'm really dismayed to see that this was reported almost two years ago and hasn't been addressed. As I mentioned, this makes the develop persona very difficult to work with—perhaps even useless. That's a major flaw that I would expect to be an absolute top priority for a quick patch release. How is this not more of a problem for people using Affinity Photo in the last two years? I have a Canon T7i which uses the CR2 format, which is very widely used. It must be affecting a huge percentage of users.
  4. I tried replying to this thread which seems related, but I didn't get a reply, so trying a new thread. When I open a CR2 raw file, the histogram appears "squished" to the left side with a bunch of seemingly unused space on the right side. If I click the develop button to move into the photo persona (without making any changes to the image at all), the histogram is more evenly distributed in a way that matches what I expect. I've tried with the develop assistant set to both 16 and 32 bit modes and the results are the same. This happens only in the desktop version of Affinity Photo (I'm using version 1.6.7 on macOS 10.14). The histogram in develop mode behaves as I would expect in the latest iPad version. Is there an explanation for this? Might I have something configured in a way that can be changed to correct this? Or is this a bug in the software? As it is, it's very hard to work with raw files on the desktop version of Affinity Photo. Attached are example histograms from the develop and photo personas, following the flow I described in my second paragraph. Thanks in advance!
  5. Is this still not addressed/fixed? I'm unclear if this is a bug I'm experiencing or if I just have something configured incorrectly. Here is an example of what I see in the histogram when I open a raw file (develop persona) and after clicking the develop button (photo persona). This is Affinity Photo 1.6.7 on macOS 10.14.
  6. Thanks for the reply, @DWright. I sent you the links you requested. I am using all the defaults Affinity Photo was set to when I installed it, so I assume that means I'm using the Serif Labs RAW engine. I opened up the file again to see if there was an obvious way to tell which engine I was using and I didn't find anything. If there's a specific way I should check which engine I'm using, please let me know.
  7. I discovered that when I export an image from Affinity Photo, a lot of the EXIF metadata that was in the original image is lost in the exported version, even if I have the "Embed metadata" option in "More" panel checked. For example, I've included a diff of the metadata present in a RAW file compared to a JPEG exported from it. Lines beginning with < are unique to the original, while lines beginning with > are unique to the export. In some cases, such as file access times, the values differ in a way that is expected, but there are many fields that are removed completely, such as "Lens ID" and all the autofocus information. Is there something I can do to make Affinity Photo preserve all EXIF metadata in exported images? I've tried on both the desktop (macOS) and iPad versions and the problem is present in both places.
