  1. When I convert a grayscale image to RGB then I get more available colours for working with this file. Is it useful to convert an 8-bit RGB image into 16 or 24-bit to increase its colour range when working on it? – Or do I work with an RGB image always in max. colours, and limit them only on Save or Export?
  2. Hi folks, anyone noticed the colour change when converting down from 32-bit to 16-bit? Searched the forum for a while and it doesn't come up. I'm working with 32-bit EXR render and at some point you need to convert down to a lower bit depth and when you do any editing on the scene, it changes the colour. Do the same in Photoshop and it stays correct. You can try it with anything: Exposure or Curve to make it visible. Set up the exact same settings in both AP and PS and convert down to 16 bit and then compare both images. Or even just do it in AP. Have your layer stack in ful
  3. Hi, so, I am reporting a rather obscure error. It may be difficult to reproduce unless duplicating fairly exact conditions, so I will be specific. System / Software Operating System: Windows 10 Pro 64-Bit 1709 Build 16299.371 Hardware: Gigabyte 15X - i7-7700HQ / 16GB Ram / 1.5TB NVMe SSD / Nvidia GeForce GTX 1070 Max-Q GPU Affinity Photo: v 1.6.4.104 Capture One Pro: v 11.1.0.140 Issue Description Using Capture One (C1) 'Edit with' to edit an existing NEF raw file, a 16-Bit uncompressed TIF file is generated and saved in C1 and then sent to Affi
  4. Summary: The image is 4988 x 2814px, 14.04 MB, 7 layers: 1 background pixel layer, 5 masked curve adjustment layers, 1 B&W layer in RGBA/32 (HDR), ProPhoto RGB (Linear). Using Document, Color Format to convert this image in 32-bits to 16-bits RGBA/16 - ProPhotoRGB takes over 8 minutes of processing time on a relatively well-spec'ed machine. Adobe Photoshop CS6 using the same image in 32-bits, similar number of layers and same color space to 16-bits in same color space takes about 5 seconds. Affinity Photo takes an inordinately long time that is not acceptable for the workflow. Details
  5. I've done some controlled experiments and had another person verify this is repeatable. Steps to produce the problem: Take photo with iPhone running iOS 11 (tested with iPhone 7 and iPhone X). Photo will be in HEIF/HEIC format Export image from Apple Photos on the Mac as an 8-bit TIFF Open 8-bit TIFF in Affinity Photo 1.5 or 1.6 (tested both) - image looks fine Export the same image form Apple Photos as a 16-bit TIFF Open 16-bit TIFF in Affinity Photo 1.5 or 1.6 and the right 10% of the image will be sort of a grey, metal-looking digital mess The same 16-bi
  6. FYI, this question has to do with AP: Looking at a recent image, I noticed some faint banding that was visible when I applied a color gradient (maybe it was there in the B&W version, but I couldn't see it). See the darker of these two images: https://forum.affinity.serif.com/index.php?/topic/20687-photos-from-a-mountaintop/(FWIW, I see the banding on my non-retina, late 2013 iMac; I haven't checked on other machines). Searching the forums I came across a comment about the "Dither Gradients" preference and the different effects if you are working in 8-bit or 16-bit (see MEB's comme
