P mode overexposing (40D)

[bekie_marie]

<p>Why is P mode over exposing? I have changed iso & white balance, but it is still doing it.<br>

Blows out almost to complete white.</p>

<p>Check your Exposure Compensation setting. You may have dialed in +2 stops of over exposure.</p>

<p>Make sure the compensation is at `0` (centred) thats on the top LCD (-2 -1 0 1 2)</p>

<p>Or... are you shooting dark subjects?</p>

<p>My camera's can't handle it when I shoot my black cat. If I want correct exposure I must set it for the grey sidewalk or the green grass and use that setting when I focus on my cat that's sitting upon it...</p>

<p>What are you shooting and how are you metering it? Remember meters generally meter the chosen object as if it is 13-18% grey. You may need to compensate if it significantly deviates from this.</p>

<p>Post an example.</p>

<p>You can also dial in a little <em>negative</em> exposure compensation. Another good trick is to set your metering mode to something like center-weighted, to set exposure to suit whatever predominantly in the middle, and ignore the edges.</p>

<p>I find night and dusk pictures in particular need negative compensation (or just use manual exposure, and dial in what works for you), the camera is always trying to make the shot look like regular daylight, and night/dusk scenes can benefit from darker look.</p>

[steve santikarn]

<p>you can send you camera to Canon for sensor calibration. My 40D was half a stop off.</p>

<p>Your camera isn't overexposing, you are. You have to learn to read the scene to adjust the compensation.<br>

Takes some practice.</p>

<p>Thanks for responses all, turns out it was jammed in +2, i didn't notice, but i'd set it to what I wanted & it would automatically jump back up...</p>
