Exporting tiff files

[gingerinpr]

Hi! 

Is it possible to export tiff 16-bit files?  I'm trying to upload astrophotography photos into Sequator.  Error received: Sorry, can not handle images with 32-bit samples (in module "image")


Per Sequator manual: RAW files are recommended. If you use TIFF instead, do not alter the linearity of data. Any processing except vignetting correction should be avoided. Sequator accepts uncompressed 16-bit TIFF.

The images were shot in raw, opened in Raw Therapee to start some edits and then the image transfers to Gimp but I'm not seeing how to export as 16-bit tiff.  

(Raw format files accepted are .cr2, .cr3, .nef, .arw, .rw2, .orf, .pef, .dng.  I don't see options for exporting as any of these extension either)

TIA

Why don't you use the RT app directly instead of using it as a Gimp plugin? Otherwise in Gimp, if the image is using 16bit precision/encoding, it is exported as a 16-bit TIFF.
