Re: Canon XTI

There are a few things to do in order to identify the problem more accurately. First, is it a "spot" or a "line" on the images. Second, is the "swipe" in relatively the same spot on multiple images. Are you using an external flash? In order to rule out the dust problem, you'll need to retreive the manual for your camera, and after removing the lens, follow the intsructions listed to move the mirror inside the camera to it's raised position and open the shutter. Once the mirror is out of the way and the shutter is open, you can inspect the camera's imaging sensor for dust or dirt. Based on your description of your problem though, it sounds as if you may be using an external flash. If you are using an external flash, you need to be certain that the camera does not exceed it's "sync speed". The maximum shutter speed used should be 1/250th of a second with this camera. If you are using a faster shutter speed, the images will be noticably darker on one half of the image. Hope this awas helpful.

I'm having problems with the settings on my Canon EOS 400D. When I take pictures in AV mode I can get quality pictures but in TV or M modes the pictures always come out so dark even when taking them...

You need to understand the relationship and teractivity of aperture, shutter speed and iso. In Av mod, you choose the aperture and the camera makes thw shutter speed agjustment, In Tv mode, you set the shutter speed and the camera makes the aperture adjustment, In manual, you have to set both shutter speed and aperture manually. If the ISO mode is set to AUTO, the camera chooses the sensors sensitivity to light automatically. Change to specific ISO
(200-400 for daylight and 799-1600 for night). Take a picture in AV mode and note what shutter speed the camera chose. Then switch to TC mode choose the same shutter speed and see if camera chose the same aperture(f-stop) you chose in first shot. Change to Manual and choose same f-stop and shutter speed the camera chose for you in the other modes. Compare all three photos. They should be almost if not exactly the same exposure wise.
In Tv mode choose a dlowers shutter speed, In Manual choose a combo of slower shuuter and wider f-stop(smaller number). Read your manual.

You may have the white balance set incorrectly. If so, set it to "auto white balance".

Canon 400D, Auto setting, images too dark

Automatic settings are not useful in all conditions. The built in flash is not good over 20 ft. Under low light conditions, an external flash is better option, but it costs additional too. Remember that shooting under low light conditions is always a difficult task. By the way, I don't know about such common problem in Canon XTi

Black screen for Shooting Canon S3 IS

I have a similar problem with my Canon S3 IS. Dark/black LCD in Shooting mode. However, I can view my existing photos in Display mode. I was about to spend money to get a Panasonic TZ5. Somehow I bumped into a solution post for S2 IS. Here is the link:

I tried their solutions twice and it WORKS. My S3 is working fine now.

Canon Powershot SD1000: LCD screen display

Hopefully you resolved this already. If not, push the "DISP." button left of the MENU button. Pushing it gives you three options: black (for discreet shooting so your LCD doesn't give garner dirty looks from fellow concert goers), liveview, and liveview with info overlayed (shooting mode, ISO, etc.). Good luck!

Why does the word, ''busy'' pop up on the canon rebel xti?

If the flash fires a full charge(eg. in a dark environment) then this message will appear whilst it recharges. If the message appears all the time and you cannot take a photo there is most likely a problem. Try taking some pictures without the flash card to eliminate that first.

Choosing to shoot Raw images

If you have Rebel XTi (400D), press Menu button.

Under the 1st Tab, the first option is "Quality" - select it. You should see 8 options from "fine L" to "Raw". Move selection using the arrow keys, and select RAW.

CANON Rebel RTI Outdoor pictures are dark

learning to use light metering correctly can have its challenge.
the manual will guide you on how to set up to read light from the subject. spot metering a dark area will cause general overexposure, or a washed out look. spot metering a bright area will cause a dark image. if you are on spot meter and shoot two people standing together against a bright lit background, your meter will see between them if they are centered, and read all that bright background, setting the camera to a less sensitive combination of aperture / shutter speed, resulting in a dark image. use field averaging meter setting and be sure you are metering the subject and not the background. try shooting a wall that is fairly clear of other colors and uniform it light hitting it, you should have a correctly exposed image. since it works in other modes (at least 1, anyway) then it is unlikely you have an exposure compensation issue. that is the only other non defect issue that would cause your problem.
once you confirm that you have these settings correct and still get a dark image, its time to have it serviced.
good luck
