Hmmm.... My three girls own a few 'large' beach balls.... Err as in like 72", 132" and a few 168" large ones lol!
Looks like I'll have to get them to make an 'instructional' photoshoot on what to do with them
Would you be using a mobile phone or a tablet to capture your images Otto? These have that orientation chip that rotates the screen when you turn the device- well it also records the orientation of the device into the photo information which then will display your image in 'Landscape' if that's how you took it. You should be able to either disable it on the device or phone- or you can correct the image on the device by opening the image, editing it (use the rotate option) then re save the image before uploading and it will then appear correctly (the right way up) for you
