I used to have a T3i and that is not something I ever had happen.
Is it possible you set a shutter delay, such as you'd use on a tripod to avoid camera shake from pushing the shutter button?
Also, try resetting all settings to default in the MENU and see if that helps.
If yo reset don't be a dope like me and be bummed out when the camera resets to take JPG shots instead of RAW shots if that is whatyou are used to, right at the beginning of a big vacation!!.

If it's any consolation, Scott, you're not alone. The same thing happened to me a couple of weeks ago.I discovered halfway through a shoot that I was shooting JPEGs. Fortunately, the shoot was mostly outdoors in fairly normal sunlight, and my 5D3 is very good at reading WB. So the JPEGs really weren't bad. But the experience was scary and embarrassing. I think the cause was that the camera had been in the Canon shop for a CPS inspection and cleaning, and I think they routinely reset the settings. I'm going to try to be more careful next time!

I'll look into resetting. F the camera (rebel t3i) changes to JPEG I can change it back to Raw format correct?
Of course. We're just talking about the default settings that you get if you do a full reset. You can always put all the settings back like you want them. But you have to remember what all those settings were. It's a good idea to have them written down.

I have T3i. While I'm taking pictures the camera shutter goes off on its own when at rest. I take a picture, and in between the walk to my next destination the camera keeps going on by itself? Any suggestions? It's so annoying!
Do you have a battery grip on the camera? I use them on all my cameras and occasionally when I'm carrying them I'll accidentally bump the shutter release, taking a series of shots.
Another possibility is that the shutter release button is sticking. It's not something I've heard of happening a lot on T3i, though. It's more common on 20D through 50D, and maybe 60D. And, more typically it causes the camera to have increasingly long delays taking shots... until eventually they just won't fire at all.
What happens is dust and dirt and finger oils gradually build up in the shutter release button, causing it to jam. I suppose it's possible it could jam "on", though it usually jams "off". All that's really needed is a cleaning. If this is the problem, there are DIY methods outlined on several websites, or you can put the camera in the hands of a professional repair tech (the better option, if possible). If you send it to Canon, they will simply replace the shutter release button with a new one. But a simple "flood cleaning" is usually all that's really needed and that's what an independent repairer will do.
If neither of these seems to be the problem, it's baffling unless you have exposure bracketing or something else enabled. But, even then, I have no idea. Maybe the camera does need to be sent in for repair.
Just to clarify... Yes, if the camera is set to JPEG accidentally, you can easily change it back to shoot RAW files. You also can set it to save both RAW and JPEGs of each image (but that takes up more storage space, of course).
However, once a shot is taken, converted and saved as a JPEG.... No, it cannot be converted back to a RAW file.
Actually, all digital cameras shoot RAW files all the time. What happens when you set the camera to JPEG is that the camera is instantly converting the RAW into a JPEG, in-camera and according to the camera settings you've made ("Picture Style", sharpening, contrast, saturation, noise reduction, etc.) It then saves the JPEG on the memory card. In the process of converting to JPEG, a lot of the originally captured data is simply thrown away and once that's done there is no way to recapture whatever was thrown away.
On the other hand, if you shoot RAW everything captured at the time of exposure is saved. Later you can "post-process" the RAW in your computer, using various softwares. If you use Canon's own Digital Photo Pro (DPP) and have it set to "as shot", the resulting JPEGs will be identical to what the camera would have produced if you'd set it to save JPEGs instead. But you also have a lot of options to change those settings with RAW files, if you wish. You also can make other types of files, instead of JPEGs. For example, TIFFs and PSDs (Adobe's own type of file) can be worked in 16 bit and higher resolutions, while JPEGs are pretty much 8 bit only. That's a difference between thousands of colors vs millions of colors, which can make a difference in finished images depending upon how they will be used.
In other words, working with RAW files you have a lot more latitude to "fix" things later on, than you do with JPEGs. Even corrections to exposure or white balance are nearly always better done from a RAW than from a JPEG.
Think of RAW as film negatives and JPEGs as the prints made from those negatives. Personally I shoot RAW most of the time, RAW+JPEG occasionally (such as when on a tight deadline where "finished" images are needed immediately). RAW are much more "forgiving" of mistakes or simply let me change my mind about how an image is later finished. So I almost never shoot JPEG only.

i was just uploading my photos and next second my EOS550D canon decided to start taking photo's and i turned it off then on and it is still doing it it will not stop taking photo's , nothing was touching shutter button it was plugged into the computer i do not know whats wrong with it at all
