Fast Picture Viewer
Not sure this is the right forum but this only happens with Sony RAW files so I thought I would start here because this issue is driving me crazy.
In in my workflow I use fastpictureviewer to review my images. I also recently switched from Canon to Sony. When I view the RAW Sony files in Fast Picture Viewer they show up smaller in size, say 6x9" instead of enlarging to the entire screen (31"). The Canon RAW files always showed up full screen. I shoot RAW compressed with my A9 because I need to get the high frame rate (I shoot sports). Maybe that is the issue? Any other thoughts? Does anyone else use this program?
