Having problems with your Canon EOS 400D / Rebel XTi Digital Camera ?

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 outside in daylight. They are not coming back with a completely blank screen as I can see the outlines of the image. Even when I try different settings nothing improves the image.


Answers :

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.

Not focusing I'm not sure what happened, nothing seems to be obstructing and to my extent of knowledge nothing has happened to my camera. However when I turn it on the lens comes out once, goes back in, and comes out again. Then the screen is blank, shows no picture until i push the play button, or until I change what picture setting it is on. Once the screen shows picture it will not focus anything. Any help here?

I think it is possible I have inadvertently changed a setting. I use this camera daily to document construction projects.

I have tried in low light levels and the images are coming out at all but, poorly. I have experimented in vein with settings. As much as I use the camera I rarely adjust any settings, don't kn

Canon Powershot A610 digital camera--LCD screen shows icons, but otherwise is blank--there is no visible movement in the lens when I take a picture without flash--have tried setting it on TV setting and taking a picture, then opening the battery cover for a few seconds after waiting 7 seconds or so, but no images on the LCD except the camera's icons--ideas? probably a stuck shutter, or is it still possibly the CCD sensor even though there's no visible movement in the lens? Ideas? Thanks!


Much more likely that it's a stuck shutter, especially for your model camera. How many tries did you give the fix? Some people stated that it took at least 15 repeated tries before the shutter opened:\015\012\015\012\015\012 ... Canon PowerShot A610 Digital Camera

Images I seem to get yellowish images and images that are really dark even when I put the flash on. The flash seems weak, almost defected. But then in the next series of shots it will work and the picture will come out just fine. All of this in the same setting with the same subject and everything else a constant too.  Help please, it seems like I must be doing something wrong either that or my camera is broken. P.S. it is brand new Amber


No that isn't it but I am not offended. The flash in fact looks like it goes off but at 10% of the full strength. I had other people try to take a picture to see if the same thing happened to them and it did and I saw them, they did not have their ha ... Canon PowerShot SD1000 Digital Camera

I just set the date stamp in the on position. Then, turned the camera off as I didn't need to take a picture. Now, when I turn it on, the lense comes out and then immediately goes back in flush and the camera is in the off position. The battery is fully charged and the camera even does this when I have it on the charger.

Blurry Pictures I have had this camera less than a year. I took it to the beach 2 weeks ago and the camera was fine. Crystal clear pictures. Then, on the last day of vacation, the pictures started coming out blurry. Even when I am preparing to take a picture the view finder is blurry. The camera is on auto focus and it is set to the shoot and click setting (little green camera). It didn't get wet at all. Anyone know if there is a setting that I may have touched or is this an internal problem.

LCD White-out I have had this Fuji FinePix A350 since Christmas 2006.

My Sony DSC-W30 has a problem. When turned on the screen picture rarely can be seen. It is either completely dark and a picture taken will also turn out dark and unseen. Sometimes the screen will turn on and off many times and then turn dark. Sometimes I can smack it on my hand and it will go black or come back on. The anti-shake button sometimes allows it to come back on. I do not have any screen messages and all the other features seem to work but in a dark unusable screen.

Canon A560 camera problem - the images are overexposed. I checked the exposure setting, AWB, and all other settings and they are all normal. There is an exposure setting where I can set to + or - 2, but setting it to -2 does not help much. Outdoor photos are almost completely white. There is some detail in black objects. Indoor photos are overexposed. Flash pictures seem OK. The picture on the display is OK. I compared some macro photos taken a few weeks ago with macro photos now. The good photo

I turn the camera on, the Canon image comes up along with various icons, but there is no picture in the viewer - and when I take a picture I get nothing. It's like the lens remains covered. Is this a setting that is somehow changed? I reset - but no change. I can view pictures on the card, so it's not the display. I can also view settings - just not any picture.
