Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your question.The problem is almost certainly not the 'shutter'. I would surmise that a setting (such as white balance or f-stop etc.) is affecting the exposure of still images. I advise you to check your settings. If necessary - and if you are willing to do so - a factory settings reset of your camera (followed by some test pictures taken) would be the best check you could do on the function of your camera.
How old is the camera? in months or years since you bought it.Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ?Has it ever been subjected to a humidity higher than 85 % or gotten wet ?Has the camera been operated in a gritty or sandy environment, such as a beach, a seaside, a construction site, or the like?
Hello Russell, thanks for your response. Not sure of the age, probably 5 or 6 years. With regards ***** ***** operating environment, the answer is no to all your questions, except it will have been used at the beach occasionally. I have tried to check settings, but must admit I got confused and gave up! Any help gratefully received! Bill
