How does your image look when it does this? My assumption would be you are in manual mode and the flashing red is because the camera "sees" your settings as being incorrectly exposed - it's trying to tell you to change your f stop or ss for correct exposure.
I have the t2i and don't recall this - not sure if it just doesn't apply to my model or whether I never noticed it... I'll have to chk when I get home tonight because now I am curious :D
@kass ahem? "Incorrect setting" suggests that there Indisputably "correct" settings... I dispute that ;p. (I very often don't listen to my camera's advice!)
@northy lol. I have noticed this on my olympus and that's how I came up with my response. When doing long exposures on your t2i do you get a busy signal after the shutter ends? I have even upgraded to 45mbs memory card and still getting this ( it does seem better, but higher grade canon users commented that they had never seen this before :p yup blowing raspberries at those big heavy cameras)
@sianipops I get the "busy" message only when I have the special noise reduction setting on that takes a "dark" shot to reduce noise... Then I get the busy signal for the same amount of time as the exposure was (if you know what I mean)
@sianipops@northy I figured it was something like this. That something is trying to tell me it's not "correct". I mean I've never listened to it so far :p
It's often seen when I'm inside on a night, so I presume its something to do with low light probably.
@northy noise reduction setting? Well I'm not surprised I don't know what or where that is - I never read the manual! @amyamoeba thank goodness we don't "listen" to out cameras. - we'd never get what we were aiming for if we did. Or we would have to ETSOOI the crap out of everything!
@sianipops I think you are missing lots of good stuff that camera can do for you. If the manual is too boring, and they usually are and never really explain the why, try the "From Snapshots to Great Shots" for your particular camera. Here's the link for the 600D at amazon.com. http://www.amazon.com/Canon-EOS-Rebel-T3i-600D/dp/032177664X/ref=sr_1_1?ie=UTF8&qid=1389033388&sr=8-1&keywords=from+snapshots+to+great+shots+600D. Jeff Revell in particular is a great writer and there are beautiful images in the book which alone justifies the US$15 price, let alone the super exposition of the neat stuff that will make over your shooting.
@amyamoeba I truly think the book I linked to above is worth $15 and a few hours read.
@amyamoeba A red shutter or aperture figure in Live View mode indicates that you are zoomed into the live view picture (i.e. you are not seeing the entire camera frame on the screen). It acts as a reminder that the exposure settings displayed apply to the whole picture, not just the zoomed-in part.
@sianipops The setting in question (there are multiple noise reduction settings on the camera) is Long Exposure Noise Reduction. This takes a second shot with the shutter closed, after the shot you took has completed, and subtracts this from the original photo, which reduces certain types of noise. In the default auto mode, it will usually kick in for exposures over 30 seconds at lower ISOs, and exposures over 1 second at higher ISOs.
It can be disabled under the Custom Function settings of your camera, specifically custom function 4, however, it is typically wise to keep it enabled, as the particular type of noise this reduces is very hard to remove in post-processing. (This is also unusual in that it reduces noise in raw files as well, where most noise reduction settings are only applied to JPEGs).
And this my friends is why I have missed 365 over the last few years. The ability to understand things in layman terms is SO MUCH BETTER! You guys are awesome!
@frankhymus thanks Frank, I haven't read the manual because it's in such itty bitty fine print! Lol. Not doing too bad, I guess for just muddling along. I am trying to get through the manual on the olympus! because I had to d/l an English version on my ipad.
@abirkill holy smackerall, look at my clever little camera! Well still not sure if that's why it's doing it as I haven't taken an long exposure over 30 seconds. Does it not come as a default setting on a 5 DII? ( just asking as that was what the other guys were using when they remarked on my busy signal)
@sianipops It's enabled by default on all Canon DSLRs. However, the higher-end Canon models like the 5D series don't immediately lock up after a shot, but will allow you to keep shooting, and will go back and do the long exposure noise cancellation when the camera is idle. (There is a limit to the number of shots you can do before the camera will lock up, but it means you see the busy message a lot less on the 5D series).
Also, because the 5D series has a small top-mounted display for showing the settings, the busy message is a lot less prominent than on the consumer models, where it appears in big letters on the back of the main display.
If you're shooting at high ISOs (I forget the exact cutoff, over 400 maybe?) it will lock up and show 'busy' after any exposure longer than 1 second, when the setting is in the default 'auto' mode. It's only at low ISOs where it needs an exposure longer than 30 seconds to show up.
If you switch it from 'auto' to 'on', it will happen for any exposure longer than 1 second, regardless of ISO. If you switch it to 'off' you'll never see the busy message again (but 'hot pixels' start to show up more prominently in your long exposures).
Some people do turn it off, either not knowing what it's for, not wanting the busy messages and not caring about the noise, or for specific types of photography (star trail photography, for example, is a case where you don't want this noise reduction enabled).

In a million years, I would not have guessed that.
Thankee Oracle Alexis!
