  1. BW Images still open as colour, and when manually converted to BW, they lose all their Foveon benefits. There's two methods to obtain BWs from Foveon RAWs, and neither of them work in AP. Images taken with the Merrill series cameras are normally able to deliver BW images without the mushiness of a CFA (colour filter array, such as Bayer), or the heavy resolution loss from an antialias filter, like with the a Leica Monokrom, yet are not prone to strong aliasing artifacts like many other cameras. All test images were captured in BW, latest camera firmware, and open properly in some other applications as BW (however, some LibRaw demosaic engine apps open them as colour, suggesting LibRaw as a possible element for the problem. Note however, that digiKam which uses LibRaw 1.19 builds these image thumbnails correctly in BW, and it is configured not to extract the embedded jpeg - it is building a downsampled version of the raw). Forcing BW RAWs to convert from colour to BW in Affinity Photo for the nearly 9 months of production and beta AP versions results in severely downgraded noise and detail and tonal range. How can I support Affinity support getting the issue posted to LibRAW's devs, so that it gets added into their mix of stuff 'in the queue' to be prioritized? I'd really prefer if it had the gravity of a respected LibRaw integrator (Affinity) verifying that it's not some lone user that hasn't done any due diligence. As well, the LibRAW folks might not otherwise appreciate that this affects all Merrill sensor Foveons (not all Sigma cameras, but a large percentage of the current user base).
  2. Hi. Was able to try out Affinity Photo (latest revision over the holidays) for two days before my trial ended. It seems my lenses were not detected, but I think that may be because of the crop factor precion: one camera of mine is crop factor 1.5, whereas the closest database matches were 1.52 or 1.53. Does it need to be an exact match (2nd decimal matching)? Also, the qualities of the program seemed excellent, except I couldn't find where to disable all demosaicing and zero the sharpening. It appeared like both were always being applied to some extent. Would love an additional 5 days test armed with how to do that: if I can, consider this a conditional sale. Thanks!
