Question about Canon EOS 40D Digital Camera

1 Answer

Manual shooting mode problem.

Hi there,

My 40D in Manual mode insists on underexposing to -2. If I press ISO on top of camera, the exposure is clearly set at 0. Consequently, image is black - totally underexposed. The dial on the rear of the camera has no effect when rotated either left or right. It's driving me mad at the moment! Is my camera faulty - it's only 2 months old. Therefore, still under warranty.

I am using the position above "on" when the camera is swithed on.

This problem does not occur in all other shooting modes.

Lenses are Canon USM f/4 L 70-200, Canon USM 100-400 IS L, Canon 18-55.

Kind regards,
Adam.

The exposure compensation dial (at the back) doesn't work when you're in Manual. In Manual, you set the shutter speed and aperture to get an image with the amount of over- or under-exposure you need. In the view finder, the "exposure meter" at the bottom shows how much light there is where the lens is pointed. When it shows what you called "2-stops", its really underexposed. Thus your black images. You need to increase ISO, open the aperture and slow down the shutter speed (or a combination of these 3 options)

Set your camera to P or full-auto. Do the photos turn out ok? If they do, then there's nothing wrong with your camera and you just need practise on the Manual mode.

    Hi, not sure if I can post comment since it was 2 years ago. But I am struggling with the similar issue - my 40d in all mode - P, full-auto, tv or av mode is constantly showing -2 under the "exposure meter" at the bottom. What else I can test? or it is a faulty camera?

When I take daylight shots that have a large portion of sky in them, they are invariably underexposed. I have tried different modes, P and manual, and all have the same result. The meter "thinks"...


There is nothing wrong with your camera. You nailed the explanation....your meter thinks there is plenty of light and cuts down the exposure. Two ways to do this: 1. Point your camera toward the part you want properly exposed and press the exposure lock button. Then, recompose, focus and shoot. 2.Press the exposure compensation button and set a lower number.

Canon 40D camera On P mode it is - 2 stops I can't find the setting to take it back to 0 and my pictures are underexposed.


When you turn on the camera, there's an option to turn the switch beyond "On", indicated by an angled line. Move your power selector switch there. Then half-trigger a scene and turn the Quick Control dial behind the camera to adjust the Exposure Compensation. Note: Being in "On" mode doesn't enable exposure compensation, leaving the settings stuck at previous.

How do i turn the auto ISO off?


In the Basic Zone modes, you don't. The camera automatically sets the ISO in the range 100-800.

In the Creative Zone modes (P, Tv, Av, M, and A-DEP), press the ISO/Flash Exposure Compensation button (rightmost button in front of the top LCD panel). This will display the current setting on the top panel. While looking at the top panel or in the viewfinder, turn the command main dial (just behind the shutter release button) to change it.

Overexposure unless in manual mode


Is your "exposure compensation" (the button with the +/-) set to "0" or some other setting?

Inconsistant exposure in Manual mode


In manual mode the light meter result is the output of setting the apeture and shutter speed. It will constantly change as you change these and the ISO until you get the desired exposure. Is this what you mean by inconsistent? If it is giving verying results in the same conditions try it with ISO 100. That should fix it

Blue corners when shooting in BULB


With the same exposure settings, you should get the same result. When using Bulb in Manual mode, you also need to be sure you have set the lens aperture to the largest opening (lowest number). And don't forget to set ISO to 1600. Since the D80 has shutter speeds as long as 30" (minutes) I recommend you use them instead of Bulb, unless you need longer.

The blue areas are heat noise from long exposure -- other electronic components near the sensor are generating heat from the constant current flow. Be sure you check your Shooting Menu settings to set Long Exposure NR to ON and also High ISO NR to HIGH.

Underexposed image on Auto mode


You can change the ISO setting also to Auto. If you have the advanced guide (see pp 80, 107).
Press the ISO button it will switch from various ISO setting to AUTO.

Do remember in Bright light , a lower ISO number like 80 will give you very fine images, while as the light level goes down, the ISO number will change to a higher number and the image will become more grainer.
I hope I could answer to your query.

How do i change ISO/ASA on the nikon N65?


The ISO is automatically set by the DX code on your film canister - if there is no code, the camera sets ISO 100. If you load canisters yourself with, say ISO 400 film, you can adjust the exposure using the exposure compensation button at the top right side of the LCD ( " +/- " ). Using ISO 400 film set the +/- to minus 2 ( -2 ) so that it will UNDEREXPOSE 2 stops since the film is 2 stops ( 4X ) more sensitive than ISO 100 film.

Exposure problem


Your 40D requires that you use an ETTL-II type flash like the Canon 380-EX. What flash are you using?

Exposure problem


If you set your meter based on the white (or substantially white) wall, as per the attachment, I would expect the image to be underexposed.
