    I found out awhile ago while trying to make an HDR, but never really bothered me till now, that I can't change the EV while shooting in manual. I can change the EV while on other settings but when you are trying to take pictures with the same aperture and shutter speed to make an HDR it's kinda an impossible task in any mode other than manual.

    I have 3 questions:
    1. Does this happen to anybody else using a D40?
    2. Does this happen to any other cameras?
    3. Can I fix this so I can use Ev in manual?


    :hail: please help

    i have the same problem on my pentax k100d

    though technically speaking you can just adjust the shutter speed for different exposures without altering anything else

    ^^^ except the EV settings give you partial f-stops difference in light from what I understand. I have never actually used this, but it is theoretically a nice "fine tuning" feature.

    I don't quite understand what you are saying.... it really does not make sense.. is it that you can't adjust exposure compensation in manual??? of course not... there is nothing to compensate when you control the aperture and shutter against a light meter.... exposure compensation only works on A, S, and P (insert canon equiv.. and of course full auto)


    when you say "i can't change ev (exposure value) in manual" ... you change the exposure value by changing either your aperture or shutter setting.... in the case of HDR .. you would adjust your shutter setting to change the value while maintaining your aperture value to provide a stable image with no difference in depth of field...

    when you say"when you are trying to take pictures with the same aperture and shutter speed to make an HDR it's kinda an impossible task in any mode other than manual".... i really don't know how to answer that.... how can you make an HDR with the same aperture and shutter speed on multple exposures???... i'm confused...

    you can change it, you just need to go to the menu and do it manually. you hit either the bottom button on the left or the one about that then use the d pad to go to EV then hit OK and change it.

    You actually can change it, dearleader... I just commented earlier that I can do it on my D300... it's a partial f-stop adjustment.

    What's the point, though? Are you telling me you people don't have shutter speed in 1/3 stop increments?

    Seriously, I wouldn't know.

    The idea of Exposure Compensation is that the camera deliberately over/under exposes compared to the light meter's reading. So if you had -2EV when you pointed the camera at a dark building, the shutter speed would increase drastically if you then pointed the camera at the sky, but you would still get the -2EV. But take the light meter out of the equation, and you can't get exposure compensation as the camera has nothing to compare the current exposure to.

    You can, however, get your own EC by adjusting the shutter speed yourself (three "clicks" of the wheel equates to one stop)

    1. Does this happen to anybody else using a D40?

    There is no exposure compensation while in manual exposure mode with a 40D.

    2. Does this happen to any other cameras?

    Yes. It's that way in the 20D, and the 5D, and most other cameras I've ever used. I may be confused about this post, but all exposure compensation adjustment would do in manual exposure mode would be to move the meter's center point around. It wouldn't change the exposure like in the auto or semi-auto modes. The only way to adjust exposure with the camera controls in manual is to change the ISO, shutter, or aperture. You'd have to have one of those on auto for there to be anything to compensate for.

    3. Can I fix this so I can use Ev in manual?

    Just read up on M mode.

    They could change the ISO, although I agree that most folks probably adjust shutter or aperture.
