Question about Canon EOS Digital Rebel XS / 1000D IS Digital Camera

1 Answer

I have Rebel camera. The lowest f-stop I've been able to set it at, whether on AV or Manual, is 5.6. Do I need to adjust the ISO speed to be able to get larger aperture?

The maximum aperture is determined by the lens. At 55mm, the 18-55mm lens will not open up beyond f/5.6. This has nothing to do with the ISO or the camera's exposure mode. If you zoom out to 18mm, you can open up to f/3.5.

The varying of the aperture with the focal length is part of the design. While it is possible to build a lens with the same maximum aperture throughout its entire zoom range, that would result in a larger and more expensive lens. For example, Canon has a 17-40mm f/4 lens. That lens weight two-and-a-half times as much and costs more than four times as much as the 18-55mm.

Is there a good reference sheet for camera settings? For example, if I wanted to shoot a long exposure at night, what are the recommended range of settings for aperture, time of exposure, etc.?


There are dozens, perhaps hundreds of books with such suggestions, but I've found that even at night, the automatic settings on my Canon EOS Rebel are amazingly good. I recommend "The Joy of Photography", if it's still in print, by "The Editors of Eastman Kodak Company". An excellent old book that covers all the basics.

The nighttime pictures I've taken were done by setting the aperture to something mid-range, and letting the camera choose the time of exposure, and taking several pictures with different settings for "over" and "under".

I have a Canon XSI Rebel that I bought new 2 years ago. For some reason when I'm in AV mode I cannot seem to get the ISO down to 100. Is there a setting that I may have missed? When I have the cam


The AV mode is for setting the aperture (ie Depth of Field).
To change the ISO setting turn the Mode dial to the P position and then turn the Main dial (next to the shutter button) to the ISO setting you require.

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.

To change the "exposure compensation" it's saying


When you change the exposure compensation setting, the camera will change the aperture, the shutter speed, or the ISO depending on the mode you're in and the shooting situation. That's what "compensation" means.

I bought this canon rebel t2 film camera recently and used film with ASO 400. Portraits look ok. but the landscapes, especially the sky area look dark and grainy. I used ef 28-135mm usm lens. Any solutions...


That's odd that the pictures would be coming out under exposed unless the previous owner has gone into the camera functions and switched the ISO from auto to manual. Another reason is that the exposure compensation has been activated and set for - exposure

Under "normal" use the camera will read the DX code on the film canisters and adjust the ISO automatically. However the previous owner may have shut this off in preference to setting the ISO manually. Even though you have ISO 400 in the camera the ISO on in the camera setting may be ISO 1600.

Checking for the Auto ISO and exposure compensation is fairly easy as you can see the film canister through the film window or you know you have loaded 400 speed film. on the LCD panel at the back of the camera is an ISO icon and exposure compensation.

Make sure the ISO for the camera is the same as what you have loaded and if the exposure compensation is to the right of 0 then the resulting picture will be dark. Move this back to the Zero.

I wasn't able to find an exact manual (if you don't have one) for your camera but have found a camera with similar. Here is a ling for that manual.

Just started using Canon Rebel EOS XSI that we got last year. Landscape picures are not crisp and clear even using landscape mode. What are we doing wrong?


Basically putting the camera in modes other than Manual, TV or AV means that's you've given up a lot of control, so the camera is left to its own devices to solve the scene. When shooting landscapes you need a large depth of field, which means the camera chooses a higher F-number for your photo. Higher F-numbers mean less light gets into the camera, since the shutter speed has to stay high enough for you to shoot handheld. So now you've got two things t work which reduce the amount of light hitting the sensor: small aperture (high F-number) and fast shutter speed. Since the camera meters the scene and has only one remaining factor to get "correct" exposure, all it can do is set the ISO according to the two other mandatory settings of F-number and shutter speed. If there's enough light (bright, sunny day) then it can remain at ISO 100, which is usually the best quality image. If there's insufficient light though, then it may go as high as ISO 800 or even ISO 1600 to allow the small aperture and fast shutter speed. This will make your photos look grainy.

Instead, I recommend that you set the camera to AV Mode, put your F-number to F8.0, set your ISO manually to ISO 100, and use a tripod. Additionally you can use the custom functions menu to lock up the mirror (prevents "slap" which shakes the camera and makes the image less sharp) and also use 2-sec timer (select it using the button to the left of "set" on the back of the camera).

Following those steps you should get the sharpest photos your lens and camera body will allow. Be sure to use autofocus by defeault and switch to manual if you want to fine-tune (or if AF is "hunting" and not locking on a target) and also turn Image Stabilization OFF if using a tripod. Good luck!

Shutter speed won't go above 200


I have two possible solutions:

First, are you shooting with the flash up or an external flash connected to it? If so, the camera likely needs to synchronize at 1/200 or slower otherwise it won't be able to take a full photo. As a safety feature to prevent that, many new cameras just restrict the ability to pick a faster shutter speed.

Second, if its not related to the flash, it might be related to the mode you are using. Turn the camera off the automatic modes and put it on an all manual setting. Change the ISO to 400 or so, got outside and aim up at the day's sky, put it on manual mode and then adjust the shutter speed. Open up the aperture on your lens all the way (turn it to the smallest number). Now adjust the shutter speeds. It should be able to go past 200 now.

F-stop issues


See pages 36&37 of the manual.

If you haven't got one, you can download it here.

In M mode...

Turn the selector dial to adjust shutter speed.

Hold down the AV+/- button (top-right of rear screen) and turn selector dial to adjust aperture setting.

As for Av mode, this is perfectly normal that you cannot set the shutter speed. Av mode means that you decide on the aperture setting and the camera (not you!) decides on the correct shutter speed.

Hope this helps,

Matt.

Trying to take pictures in low light conditions inside a theater.


when you use high ISO like 800-1600 it will create big novice on image, and when you using law ISO it will be dark for sure.
so the solution is switch cam to TV mode and put into very law shutter speed and use ISO 200-400,make sure you are connected to tripod or else you will not get fine results with law shutter speed. point is when you use law shutter speed camera will take more light to censor even with law ISO your images will be perfect.
