  1. I've been scanning my old 35mm negatives with a Minolta Minolta Dimage Scan Dual IV so that I can put them up on my website. The negatives and all black and white and in need of a bit of attention, so my plan was to run them all through Affinity Photo to remove any dust and scratches and tweak the levels. I did this a few years ago with an old copy of Photoshop CS2 with no issues, so assumed the latest version of Affinity Photo should have no trouble. As I did the last time I scanned a batch of negatives, I have been scanning them with Vuescan as 16bit greyscale TIFF files. When I open the resulting TIFFs in Affinity Photo however, they are opened in the Develop persona with the picture completely blown out. On some occasions they fail to open at all and leave either a blank window reading 0x0 pixels, or crash the app completely. I'm happy to provide a copy of the error log if you think that would be helpful. I can kind of fix the blown out image (for the ones that do actually open) but it really shouldn't be necessary. The files which fail to open at all open fine in Preview, Photoshop CS2 and pretty much anything else I try to open them in. As it is, I am getting better results out of the almost 15 year old Photoshop CS2 than I am out of Affinity Photo. I know I could just use Photoshop, but my copy won't run on my current Mac so I have to open my TIFF files on an old Windows 7 machine. I would much rather however use Affinity Photo as I otherwise find it works very well for my needs. Is there any way in which I can open these TIFF files normally in the photo persona? Is this a bug or the intended behaviour for 16 bit TIFF files? Any help would be much appreciated. Thanks
  2. What is the advantage of doing tonal corrections in "Develop Persona" when compared to do the same changes in "Photo Persona" in RGB 16 bit mode? My usual workflow is: I open a RAW file in affinity. Just set to output profile Prophoto and color depth to RGB 16 bit. Then click develop and go to Photo persona and do the tonal changes there. Am I loosing anything by skipping the RAW development and directly going to Photo Persona with 16bit image? Thanks
  3. When I import a RAW file taken on the IPhone and develop it in Affinity’s RAW persona, and then do my processing and save the resulting AFF file, the thumbnail of that image shows in the Home screen as RGB 16 bit below the image dimensions. I’m a little confused; is this 16 bit/channel in the RGB, or the rather restrictive 16-bit RGB format? Sorry for a rather basic question, but I haven’t found an answer online. Thanks in advance.

  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: The machine: Windows 7 Professional 64-bit up-to-date per Windows Update Service Pack 1 Processor: Intel Core i7-3770 CPU @ 3.40GHz 32.0 GB RAM Windows Experience Index 7.7 (on a scale of 1.0 to 7.9) Graphics card: GeForce GTX 970 version 385.69 NVIDIA Control Panel reports (see attached PNG) More details on machine in attached PNG. Disk C: is a SSD and has both Affinity Photo and Adobe Photoshop CS6. The software: Affinity Photo 1.6.1.93 RAM Usage limit 25,599 MB Renderer: Default (NVIDIA GeForce GTX 970) Adobe Photoshop CS6 64-bit, using the NVIDIA GeForce GTX 970) Using Photo Affinity's Document, Color Format, RGB 16 bit it takes slightly over 8 minutes to have hourglass disappear and the RGBA/16 - ProPhotoRGB to appear. During this time Windows Task Manager reports (see attached PNG's). CPU utilization by Affinity Photo is essentially 100% during this time. Trying 32-bit to 16-bit conversion on the same image in the beta version 1.6.1.93 (Beta) does not result in Task Manager reporting "Affinity Photo (not responding)" but if anything the conversion takes even longer at about 8 minutes 55 seconds. Doing this 32-bit to 16-bit conversion of same image and same color spaces in Photoshop CS6 takes about 5 seconds of processing time. Machine Info 1.pdf
  5. I love Affinity Photo and Designer. I plug them continually, however, please add support for 16 bit PNG exports!
