Export TIFF without compression in Affinity Photo

Recommended Posts

Using Affinity Photo 1.6.5.135. Is there any way to export a TIFF image without compression?

It seems that compression is enabled by default and there is no way to disable it. I'm using View NX-i and Capture NX-D as my raw converter and after an image has been worked on in Affinity Photo and exported I cannot open it in the for mentioned Nikon apps.

Would be great for Affinity to have this feature.

The latest Affinity Photo 1.7 beta version for Mac allows the user to select the compression method for TIFF export. I would hope we’ll see this added to a Windows beta version quite soon.

TIFF compression option is now available in Windows beta 1.7.0.284 :)

Needs tweeking but I assume this will be ironed out in future release.

When you select a LZW or no compression and exit the export settings box there is no way of telling what settings you have set. If you go back into the Export settings and select compression options you will notice "ZIP" is set as it's the default. So you will need to select a compression option again before you exit and export the file.

How can you find out what compression is used after file has been exported?

View the file with a program that can display that information. On Windows, IrfanView, for example. Or Exiftool.

FYI

I tested exporting a file in all 3 compression modes (ZIP, LWF and no compression) and viewing the file info in IRFANVIEW shows compression as "AdobeDeflate" for all 3 files.

Note: I created a new profile for no compression and LZW mode based on existing "TIFF RGB 16-bit" profile.

I think that's been reported in another topic. It seems that (on Windows, at least) we have the option but it's not being used.
