John Rostron Posted February 28, 2019 Share Posted February 28, 2019 I use VueScan to scan lots of black-and-white images. Within VueScan, I set the input as B/W and the output to 1-bit Tiff. After saving the image, it automatically opens in Affinity Photo with the message that the default profile is automatically being applied. This means I get an 8-bit RGB image. Now I know that Affinity does not (yet?) support 1-bit images, but it is annoying to have to set the image to Greyscale every time. I tried to look up this Colour Profiling, but it seems that it is a global setup that will affect any unprofiled images that it loads. VueScan says that the saved tiff file will be 'profiled' whatever that means. I find that Corel Photo-Paint does not do this. It loads the tiff as a 1-bit image. Is it possible to prevent this happening? If I am about to scan a batch of black-and-white images, would it be possible to prevent this default profile being applied? I posted a similar query to VueScan support and got the following reply from Ed Hamrick: Profiles only work for scans that are in color. They don't make any sense for 1 bit per pixel, so I don't store a profile. John Quote Windows 11, Affinity Photo 2.4.2 Designer 2.4.2 and Publisher 2.4.2 (mainly Photo).

walt.farrell Posted February 28, 2019 Share Posted February 28, 2019 From Ed's answer it sounds like you could scan as 8-bit grayscale rather than 1-bit and VueScan would save the profile.

John Rostron Posted February 28, 2019 Author Share Posted February 28, 2019 OK, @walt.farrell, I'll try that.

However AP still tells me it is assigning its own profile. (The box disappeared before I could see which profile.) So it would appear that: Setting VueScan to 8-bit greyscale results in an 8-bit greyscale file in AP. OK there. Setting VueScan to 1-bit B/W results in an 8-bit RGB file in AP. Seems that is something I will have to live with. John Quote Windows 11, Affinity Photo 2.4.2 Designer 2.4.2 and Publisher 2.4.2 (mainly Photo). CPU: Intel Core i5 8500 @ 3.00GHz.

walt.farrell Posted February 28, 2019 Share Posted February 28, 2019 You might examine the 8-bit file that VueScan produced to see if it has a profile or not. Exiftool should be able to tell you take. Or if you attach a file here others can check for you.

Exiftool should be able to tell you take. Or if you attach a file here others can check for you. This is no longer anything that I am pursuing. Thanks to @walt.farrell's suggestion, the matter is now resolved. Anyway, thanks for the offer. John Quote Windows 11, Affinity Photo 2.4.2 Designer 2.4.2 and Publisher 2.4.2 (mainly Photo).
