Shutterspeed

[linda_roina]

<p>I have a Nikon D300. At the moment it has a Nikon 17-55 attached. My question is why when I have it in "Manual" mode does the shutterspeed change from where I set it. Have I got something set wrong in the menus? </p>

<p>Linda,</p>

<p>When you have your D300 in <strong>M</strong> for manual mode the shutter speed is set by turning the rear command dial on the camera body. In <strong>M</strong> mode only your manual input can change the shutter speed.</p>

<p>Do you perhaps have Bracketing turned on?<br>

That would alternate the shutterspeed after each shot, it could go in groups of 3's... if you press the button on the front of the camera, below the lens, and it shows 3F 1.0, or something like that not starting with 0F, then you have bracketing turned on... Turning the dials will either switch the First or the second group. 0F at the front turns bracketing off. I use bracketing for everything but my flash pictures of cats and people at 1/180s f/8.</p>

<p>Robert has a very good point here - I do remember accidentally engaging the bracketing mode on my D300.</p>

<p>I think when you switch to M, it remembers the last speed you were set to when there last? Is that the answer to your question?</p>

[Ed_Ingold]

<p>Peter has the answer. The setting in one of the auto modes does not transfer when you switch it to manual.</p>

<p>Use the meter bar in the viewfinder to set the exposure, or simply transfer the auto reading manually.</p>

<p>What I am trying to say is when I set the shutterspeed while in the "Manual" mode it moves to another setting when I move the camera around. In "Manual" mode shouldn't the shutterspeed stay where you put it until you dial in a different number? </p>

<p>In manual mode both the aperture and shuttter speeds should at the value you have set whether you point the camera to the sky or into a cave. The meter will see the change of light and suggest you change the settings for proper exposure. It sounds like you don't have it in manual exposure mode or there is a problem with the camera. You did change the exposure mode through the menu or top button set? You should have P, S, A or M options.</p>

<p>Linda,<br>

is it possible that you accidentally hit the dial which controls the shutter speed? I shoot a lot in A mode & I have on so many occasions changed my f/8 to just about anything & everything. It is easy to do as your setting isn't "locked" in. It's set where you placed it - until something changes....<br>

<p>Do you have auto ISO turned on? If so, turn it off and see if that fixes your problem.</p>

<p>I don't mean to insult your intelligence, but are you sure you have the camera set to manual <strong>exposure</strong> mode, or perhaps to manual <strong>focus</strong>?</p>
