  1. Resolved: Can confirm 1.7.1.404RC2 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 1.7.1.367 and .404RC2 has EXIF and focus info, but recent prior betas were p
  2. 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 1.8.4.665 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 (1.8.3.641), 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
  3. BW Images still open as colour, and even if converted to BW, lose all the Foveon benefits. There's two ways to obtain BWs from Foveon RAWs, and neither works. Similar crops below from the same image, all at 200% zoom (slight variations in cropping). Most recent of multiple posts (prior beta) Above: AP 1.7.2.414 choosing BW Above: AP 1.7.2.414 choosing BW and only using blue channel Above: IrfanView 4.5.2 as opened (uses DCRaw) Above: Sigma Photo 6.6.1 Export using Blue Channel only
  4. Just an update after doing some testing last night with 1.7.1.385, and the ongoing denoising/demosaicing issues (not sure which was causing the problem) which made Merrill (SD and DP Merrill series cameras) barely usable, now appears significantly improved. Before, there was so much noise evident (mostly chroma, but also some luminance) even with reasonably well exposed images, that to get rid of sufficient noise resulted in also removing so much detail that the output almost looked like a stylized cellphone oilpainting filter. NOTE: this problem only occurred with the Sigma Merrill cameras, a
  5. Affinity Photo Desktop Windows, latest (non-beta) rev: 1.6.5.135 Win 10 x64 up-to-date, 16 GB ram, >45 GB on SSD, >400 GB on HD & defragged no SMART errors). GTX 1060 6GB. Camera: Sigma SD1M (M for Merrill, inventor of the Foveon sensor), X3F RAW files. Neither of these issues happen with my SD14. Reproducible. Two unexpected behaviours both occurring during RAW import, even with the same image file. Behaviour One Import B&W RAW image, and B&W setting is lost (appears with separate colour channels). Camera has two methods for obtaining high quality B
  6. sd Quattro files still look muddy. (Compared to a TIF out of sigma photo pro, opened in affinity!) DP2 Quattro files look like mud too. Occasional artifacts and colour cast (again, missing from a TIF SPP->Affinity) Merrill files have a crazy colour cast As before, onedrive of raw files here: https://1drv.ms/f/s!ArciU0vVYB2QiWmyBYHTBFZ60Ee4
  7. I have a Sigma DP2 Quattro and while that camera is partially supported, I get better results from converting X3F files to DNG with X3F Tools and then develop the DNG in Affinity Photo (adjust white balance tint and it looks pretty good). The problem is that Photo doesn't honor the crop instructions. It does honor the size of the output file (5424 x 3616), but displays thick black borders along two sides and cuts off the opposite sides. Older versions of Iridient Developer used to do the same but their newest version works correctly. Here's a link to the tool in question: https://gith
