N'Awlins Contrarian posted a topic in (Pre 1.7) Windows resolved threadsI'm using Affinity Photo 1.6.4 on a Windows 7-64 bit Home Premium machine. I have some TIFFs that Affinity Photo does not open correctly--even though Windows Photo Viewer, DxO PhotoLab, and GIMP open them fine. For whatever it may matter, these TIFFs are grayscale instead of RGB, and are 16 bits per pixel. Opening the file brought up the Develop persona instead of the Photo persona. The file displayed completely wrong--grossly over-exposed, high contrast, like somebody had grabbed the top right of the tone curve and dragged it almost all the way to the left edge (while leaving it at the top). The first attachment is a screen capture from immediately after opening the file. The second attachment is a screen capture of the same file opened in Windows Photo Viewer, which displayed it correctly. Back to the Affinity screen capture. Note the histogram at top right, which seems to correspond to what I see. Maybe more significantly, note the "RGBA/32 (HDR) - RAW" text toward the top left, which seems to be wrong. In other words, Affinity appears to be misconstruing what it's opening. Just as an experiment, I clicked Develop, but the image did not get fixed or even change appreciably. Also: this is a big file, over 150 MB and 80 MP (it's a scan of an old 8x10 negative). In case you want to experiment, the file's page at the U.S. Library of Congress is: http://www.loc.gov/pictures/collection/det/item/2016796043/ and the direct location of the full-resolution TIFF is: http://cdn.loc.gov/master/pnp/det/4a20000/4a23000/4a23600/4a23684a.tif Thanks!
Subclavius posted a topic in (Pre 1.7) Windows resolved threadsAffinity Photo 18.104.22.168/Windows 10 Am trying to load a large TIFF file from the scanner. It is a 16 bit file with dimensions 12163x15348 (see pic from Windows). However, when loaded (apparently without error) into Affinity Photo the file size is drastically reduced to 1090x1375 (see pic from AP). (1) This file loads correctly into Lightroom (2) A smaller version of the TIFF file (4561x5756), also 16 bit, loads correctly into AP. Any help would be much appreciated. Nigel
