Star stacking — TIFF files without alpha channel
I was using ON1 to prepare nightscape / milky way RAW images for stacking by Starry Landscape Stacker (Mac OS). I exported the images as TIFF files which were rejected by Starry Landscape Stacker (SLS) as mask files.
Reviewing the SLS website, I discovered a posting indicating an issue with ON1 TIFF files and suggesting one remove the alpha channel when saving TIFF files. I understand from ON1 support, that this is not possible until a development change is made.
My workaround has been to import ON1 TIFF files into Luminar 2018 and get Luminar 2018 to save the images as TIFF files that can be imported into SLS.
