I'd like to point out this isn't a bug exclusive to the X-H2 (I reported it initially after discovering on my X-H2s and confirming it on old photos taken with my X-T2). I've tested it on other Fujifilm raw files and the problem appears universal to every camera with X-Trans sensors. Given Adobe's indifference to good rendering of that colour filter array, I have low hopes of this issue being addressed with any priority, if at all.  ... View more

Adobe is too busy fixing typos in Polish translations instead of handling the real problems. It's been ten years since this thread was opened, and their best solution is a computationally intensive process that litters your storage with additional files at twice the size of the original raw.    At least allow us to export files using the Raw Details method, so we're not juggling duplicates! ...

Out of curiosity, I tried to see where any artifacts are present when I use Raw Details instead of Denoise, and there is evidence of a similar, but not identical, pattern of artifacts. Notice the artifacts present with a substantial shift in colour.  This affects Fujifilm X-Trans RAF files from both cameras I've tested, which used different sensor generations (X-T2 and X-H2s). ...

Confirmed, the same large blocks appear when using Camera Raw.  I want to emphasize that no evidence of the artifacts exists in the Enhance preview window.  ... View more

I'd argue your Topaz example is the preferable version. I'm not expecting miracles in such deep shadows—it's mostly noise. It'd be nice not to have dreamt-up colours, though.  ... View more

Again, I must insist this isn't an extreme ISO image (640). It's a photo with extreme exposure and shadow adjustments made in Lightroom.  I was able to recreate it using a different and much older fujifilm model (X-T2). That raw file is attached above in one of my replies.  Perhaps it's an artifact specific to X-Trans sensors? Frankly, I wouldn't be surprised by that given the decade of complaints with how CameraRaw treats those files.  ... View more

This bug goes beyond this particular image.  I just want to clarify: the photo was captured at ISO 640. The stated exposure compensation was applied to preserve highlight detail. There is no ISO 10,000 equivalency. The image appears as intended when you open it in Lightroom using the default settings. There was no intention on my part to process the photo with a +5 Exposure adjustment in Lightroom. I discovered the bug by accident. The RAF was denoised, and I was playing around with the resulting DNG when I noticed some odd colour artifacts, so I looked deeper into the shadows... ... View more

The exposure bias (i.e., the exposure compensation) applied to the photo would have no additional impact on noise versus what we'd see had I used the same aperture, shutter speed, and ISO values in manual exposure mode. It's just a bias versus the camera's standard exposure index for that frame.  ... View more

We can call it a bug or a result of how Denoise interprets the underlined colour in the deepest shadows, but the fact remains: in the deepest shadows, Denoise is generating colour patterns that are not present in the source raw file. It's not even doing it consistently across different computers, to boot.    To ensure this wasn't caused by some aspect of the lights in the scene (doubtful), I Denoised and pushed a photo from months ago of a different location. Further, to ensure this wasn't some aspect of my camera or artificial lights, I repeated the process on a photo from last year taken with a different Fujifilm (X-T2 vs X-H2s) camera. The results are identical—bluish-reddish vertical banding in the deep shadows (not checkerboard like in your results).        The new and old files are here: https://1drv.ms/f/s!AjAOXAIjC1XCgaMA235qbZFycHrnZA?e=ct6D9y   ...

I've also been disappointed in the speed of face detection in LrC since the feature's release years ago. The interface needs a revamp. It asks for too many confirmations.  ... View more

Sorry for missing the raw files that were omitted from the attachment. You can download the original Fujifilm RAF and corresponding DNG (Denoise amount 30) from my OneDrive:  https://1drv.ms/f/s!AjAOXAIjC1XCgaMEHGfxMYIMFnHMnw?e=lzb5o4 ... View more

I've noticed that although the AI denoise feature produces excellent denoising results, it also creates odd magenta and purple streaks near photo edges. I've observed this only in Fujifilm X-Trans files saved specifically as "lossless compressed" – the "uncompressed" raw files are unaffected. It afflicts all such raw files captured by my X-T2 and X-PRO2 cameras that I've checked, regardless of starting ISO or strength of the denoise algorithm. Some key specs: 1. Lightroom Classic 12.3 2. MacOS 12.6.5 (this is a "Hackintosh" running an Intel i9-9900K and AMD Radeon VII 16 GB; I've never experienced such artifacts before). 3. Open a Fujifilm X-Trans raw file saved as "lossless compressed" and enable the AI Denoise function. In the preview, scroll to the left, top, or right edges, or confirm the file's creation to see the magenta streaks. 4. First attached photo shows the result, and the second image is a regular pre-ai denoise export.     More granular system specs: Lightroom Classic version: 12.3 [ 202304101834-a085245c ] License: Creative Cloud Language setting: en-CA Operating system: Mac OS 12 Version: 12.6.5 [21G531] Application architecture: x64 Logical processor count: 16 Processor speed: 3.6GHz SqLite Version: 3.36.0 Built-in memory: 32,768.0 MB Real memory available to Lightroom: 32,768.0 MB Real memory used by Lightroom: 8,309.0 MB (25.3%) Virtual memory used by Lightroom: 57,278.0 MB Memory cache size: 2,371.6MB Internal Camera Raw version: 15.3 [ 1451 ] Maximum thread count used by Camera Raw: 5 Camera Raw SIMD optimization: SSE2,AVX,AVX2 Camera Raw virtual memory: 1687MB / 16383MB (10%) Camera Raw real memory: 1799MB / 32768MB (5%) Standard Preview Size: 1920 pixels Displays: 1) 1920x1080 Graphics Processor Info: Metal: AMD Radeon VII Init State: GPU for Export supported by default User Preference: GPU for Export enabled ...
