Calum Posted April 17, 2018 Posted April 17, 2018 Hi I know there are many threads about this but I have not managed to find a solution. I have opened my Sony raw files, ARW, in the Develop persona, edited very slightly then exported to tiff. The problem occurs when I try to load them in Sequator to stack them. The files are not recognised and I know that this program can load tiffs. Why do Affinity exported tiffs not work? It seems this has put many people off Affinity and I cannot easily find an answer help please! thx Quote
firstdefence Posted April 17, 2018 Posted April 17, 2018 Are the tiffs exported as 16Bit? Might also be an idea to ask the author of Sequator what settings are appropriate for export to Sequator from Affinity Photo, he can download the trial and advise.

Staff Gabe Posted April 17, 2018 Staff Posted April 17, 2018 Hi @Calum, Can you please attach the tiff file so we can have a look? Can you open the Tiff in any other apps? Or is the issue only "Sequator" related? Thanks, Gabe. DM1 1 Quote
Calum Posted April 18, 2018 Author Posted April 18, 2018 Gabriel thanks for responding. I intended to upload tonight but ended up battling with Norton again - what a lousy outfit. I will try again tomorrow. I can open it in other programs but I don’t think the issue is with Sequator since it can open normal tiffs. Quote
Calum Posted April 18, 2018 Author Posted April 18, 2018 Firstdefence yes they are exported as 16bit. Sequator has a sole author so not sure how to contact but I’ll look into it. Thanks for responding. Quote

Calum Posted April 19, 2018 Author Posted April 19, 2018 @GabrielM Attached (hopefully) is one of the tiffs exported from develop persona. Any advice would be gratefully received! @firstdefence I have mailed the author and I'll see what I get back but I think from his comments he is an Adobe user. No1.tiff Quote
Staff Gabe Posted April 19, 2018 Staff Posted April 19, 2018 @Calum i have tried several apps including MS Paint and the image opens just fine. I'm pretty sure the issue would be on Sequator side. Sorry Quote

It accepts the TIFFs produced by many popular software, e.g. PS, LR, FastStone, etc. But there may be some format it does not support. I guess the Affinity exported Tiff is just not popular or stable enough - shame. Thanks to those that responded!! Quote

I'm have successfully opened your file with Windows Photo Viewer, DXO OpticsPro 11, Corel Paintshop Pro 2018, IrfanView, XnViewMP, and Gimp. Possibly it is more complex or uses options that Sequator (or its library) are unable to process. However, I will mention that: Gimp gave a warning about an incompatible type for the RichTIFFIPTC tag; and Corel Painter refused to open it, saying "TIFF file has an unsupported number of bits per sample". Acccording to IrfanView the file has 48 bits per pixel and the EXIF info shows, for BitsPerSample, "16 16 16".

Hi Walt, Very kind of you to check - I also tried my old copy of GIMP but it did not support 16-bit tiffs. I imagine Corel Painter is the same. Calum Quote

I imagine Corel Painter is the same. And, perhaps, Sequator has that limitation, too. In that case you could simply export your file as an 8-bit TIFF rather than a 16-bit TIFF.
