I assume you weren't using fill in flash. The camera can lock up for several reason like if it can't find a focus point due to low contrast . Thhis usually happens in dim light but can also happen in bright light if all the sensor were reading the white dress. If it really is an exposure problem you should just be able to use the exposure compensation switch and cut out two stops of light. Also if light was striking the eye piece of the camera it can throw stuff off but normally one has an eye block this from happening. If you are shooting negative film you are ok because of the latitude. If you were shooting slide film then you probably have a big problem. n a message dated 9/23/02 10:54:43 PM EST, shutterbug123@hotmail.com writes: > Hi everyone, > > While shooting an outdoor wedding today (in bright sunlight), my Minolta > xtsi locked up on me 3 times...everything appeared to be on, but it would > not fire.(Can't wait till I can afford med. format).
