Originally posted by BruceBanner Ok, that's interesting. I was just thinking about it, and sometimes when I am out and about I deliberate choose 1:1 for composing the shot. The thought then struck me that perhaps it was cropping the RAW and like how we have the APS-C genuine crop perhaps the same benefits would be had in terms of buffer limits and what not. I am somewhat saddened to hear that is not the case...
On the other hand I didn't think this was so.. I thought I had imported a 1:1 RAW crop into LR and it showed only 1:1 and not the original 3:2 shot? So if the crop is a mask, but not presented itself like that in LR/PS natively, does that mean you can get the mask to go away and get a 3:2 shot back of the 1:1 crop taken an the time (somehow with some software)?

When K-1 was introduced I as always used Capture One Pro to develop the raw files. Capture One Pro doesn't use the raw internal preview it generates it's own that fits the inidvidual demands (monitor size etc.).
When we got K-1 Square Mode with a firmware update I immediately realized that Capture One Pro didn't create Square previews for my K-1 Square Mode shots. So I reported this as a bug to Phase One. It didn't last long and we got the bug fix to get the expected Square preview in Capture One Pro. Other software like PT Gui never offered this correct preview. So you have to remember that you intended to make a square image. I don't think I can decide in Capture One Pro to change a square mode raw shot to show as a 3:2 full screen shot. Maybe Lightroom offers this?!
My mainly used raw converter is Capture One Pro. But sometimes I try or use others for special cases. Here are my findings concerning handling K-1 Square Mode shots ...
Raw developers that
don't show square previews for K-1 Square mode images: Affinity Photo, Raw Therapee, PT Gui (I think it uses DCRaw as raw converter)
Raw developers that
show square previews for K-1 Square mode images: Apple Aperture (!), Capture One Pro, Darktable, PDCU
The funny thing is, that Apple Aperture 3 handles the K-1 Square Mode information correctly. It proves that it's a basic functionality that's related to the basic os raw support and not anchored in the application (that's not updated since years) - at least in Mac OS. Unfortunately Apple Aperture 3 doesn't work anymore from MacOS Catalina (MacOS 10.15) on. Until now I didn't upgrade MacOS.
If you use a lens that in FF mode shows the image circle or strong vignetting you may decide to shoot in K-1 Square mode to create a panorama using PT Gui. Then you should first convert your square captures to square tiff images and based on these images create your PT Gui panorama. If you don't do so, you'll get darker areas in your resulting panorama image since the vignetting areas are going into the panorama computing equation. I know this because of having made this experience. So - it may be important to know how your imaging software/ raw converter handles K-1 square mode.
Sorry, if I dived a bit off-topic.
