Hey guys, 
I found this weird problem, while importing 32bit .tif files. Photoshop and Windows can preview them normally, but Affinity is adding white boarders around the white areas.

Hope to get help here... Any idea what I am doing wrong?

Thank you

Jonny

Hi and welcome to the forum

 

we would need the actual tiff file to check.

it looks like a 32 bit greyscale image. Affinity seems to import this incorrectly (displayed as GREY/16, as Affinity does not support GREY/32).

Assume this is a bug (if it's rated as missing feature, Affinity should provide an error message instead of silently importing it wrong).

If possibly, try tiff/16, or EXR, HDR if you need to use 32 bit colour channels.

I edited the file with Mac Preview and exported as TIFF GREY/16. that file imports correctly in Photo.

Windows has some Apps to edit images, try them out. On Mac, the Preview Apps does the job.

Last resort option: try snipping tool, but this will probably reduce to 8 bit color depth.

Yes, would make sense to file this as bug. But it is a kind of grey area, Affinity may decide to give an error message "unsupported file format" instead of correcting the bug.

In my opinion the lack of a message and/or opening the unsupported file format is the bug.

Mac Pro (Late 2013) Mac OS 11.7.1 
Affinity Designer 2.0.0 | Affinity Photo 2.0.0 | Affinity Publisher 2.0.0 | Beta versions as they appear.

I have never mastered color management, period, so I cannot help with that.

Or do you have a tool, where I could convert the image to hdr or exr 32 bit?

Try ImageMagick
convert 32bit.tif -define exr:color-type=Y -compress zip 32bitY.exr
produces an identical view to opening the original in CS2, it's slightly different from NotMyFault's
