Hello, I am out traveling on holiday with my Fuji GA645. I have just finished a roll of film when something has gone drastically wrong. After the 16th shot, instead of the film rewinding, the camera seems to have jammed and not rewinded. The shot count number (16 in this case) is flashing. How do I recover from this? I dont want to lose the images on this roll of film. Thank you for sending this urgent help! I am out on a trip making photographs and have lost the use of my camera.
