Canon T4i sounds like shutter is sticking.

At first it sounded like a long exposure, causing overexposed photos.  Now it still sounds like shutter is lagging, sticking, but the photos seem underexposed and blurry around the persons body.

If you are shooting in low light, with too low an ISO, you are probably getting really long exposures that are blurred due to either camera shake or subject movement or both. Try increasing your ISO and see if that helps.

 

Underexposure might be due to having Exposure Compensation set toward the - side.

 

If you have Long Exposure Noise Reduction turned on, that will make the camera take a second "blank" shot with the shutter closed, that it uses to compare with the first exposue to deduct noise from it. The second exposure is the same duration as the first and if it's cancelled in the middle of that second exposure, both image files are discarded (probably not the problem here, since you wouldn't have any images at all if this occurs).

 

Without more info about your camera settings and seeing sample photos (with the EXIF still attached prefereably), these are only guesses.

Can you either describe the shooting situation:   Are you indoors or outdoors?  If outdoors, is it daylight or is it night?  Also... what shooting mode are you using on the camera (Auto (green box), P, Av, Tv, etc.)?  If any any mode other than full auto, what ISO are you using?  

 

It would be great if you could post an example WITH the exposure data included (this is automatically embeded in the image's "EXIF" data if you don't remove it when exporting or uploading -- many of us have a browser plug-in which allows us to see the exposure settings in the image when we view it online.  Again... that only works if the EXIF data has not been removed.)

 

I ask this because it's entirely possible that the camera is actually using a correct exposure and you're getting the long shutter time because that's the best it can do given the circumstances.  But we don't have enough information yet to determine if that is the case.
