After adding 25 colour graded images they stitched fine however when trying to add a single image to the 25 images the other 25 images become very under exposed and the single image I added very over exposed. This happened on Pro 12 Beta 14 & 15 however it never used to when I 1st started using 14. Updated to Beta 15 but it’s still a problem. Have I touched a setting somewhere or is this a bug. Attached photo should explain it better.
