<p>I am having some difficulties while using <code>Manual Mode</code>.</p>

<ul>
<li>Sometime face become so <code>Dark</code> as I don't know what should be the aperture.</li>

<p>So can anyone guide me what will be the global settings or anyone can differentiate about the aperture &amp; focal length.</p>

**Camera : Canon 650 D**

I am having some difficulties while using `Manual Mode`.

* Sometime face become so `Dark` as I don't know what should be the aperture.
* In night shots, Grains appears if I set ISO to low it becomes dark video If i set it to `High ISO` Grains Appears.

So can anyone guide me what will be the global settings or anyone can differentiate about the aperture & focal length.

There is no global setting that works in all these conditions. The solution is to light properly and expose properly for the conditions. It's hard to give specific advice because you don't say what you're shooting in these low light conditions or what venue you're shooting in. Here are the general solutions:

1. Do you have the option to increase the lighting? If so, that's you're best bet. Note that you may not need to buy more lights - reflectors can do wonders and are very cheap.
2. If you can't increase the lighting, the next best thing is to open the aperture. However, that causes your depth of field to become more shallow, meaning it's harder to focus on your subject and keep them in focus, particularly if they're moving.
3. Decrease the shutter speed.
