Really excited to see the activity supporting X3F files: thank you immensely for all these efforts. I think there's been a small oversight in packaging the 184.108.40.2065 Photo Beta, because when you open an X3F file, it immediately crashes to desktop (even before fonts are loaded, etc.). As a control, I also retried the most current non-beta Affinity Photo (220.127.116.111), and that can still open X3F files without crashing out. I tried this new Affinity Photo Beta using X3F RAW images taken using: Max resolution Low resolution B&W Taken with a Merrill sensor Taken with an older SD14 Sigma. I tried manually browsing and opening the varied test set of files from within Affinity Photo, as well as using Windows Explorer's "Open with..." and choosing both 'Affinity Photo Beta' and 'Affinity Photo'. The issue is consistent for all these (above) X3F files opened with this newest beta. But even with a CTD, I'm still ecstatic for the developer attention after all this time.
Resolved: Can confirm 18.104.22.1684RC2 has full control over noise removal, especially chroma noise (working since recent betas: thank you so much), and is fully usable now on Sigma Merrill cameras. Also, only as of 404RC2 is EXIF and focus reliably consistent. Outstanding: BW images still open as colour: no benefits from in-camera BW captured images. Additionally, some BW images shot at higher than base ISO open like linear exposure (super dark). Quick test images (apologies for quality): 6745, ISO100, BW: in 22.214.171.1247 and .404RC2 has EXIF and focus info, but recent prior betas were partially missing EXIF & focus metadata. In all versions, these open as colour (should be BW). 6742, ISO800, BW: Very difficult trying to extract a workable image from these RAWs (shot higher than base ISO). Opens fine in other RAW editors. Why Not Use Normal Colour to BW (Post-processing Conversion): The key issue behind this is that the Foveon Merrill can capture the full spectrum at every single 'pixel' (photosite), and output it in BW (like a Leica M Monochrom). No demosaicing is required (or ever wanted). When these are shot as BW in the camera, Affinity Photo opens them as normal colour images, and loses all their benefits. For instance, Foveons also normally capture full spectrum at every 'pixel', and when all treated as BW, you can get 3 times as much sampling per pixel as the monochrome Leica, for improved noise.
