[QUOTE="yauman, post: 414281, member: 15418"] Ok, you are "over thinking" this. It really is quite simple so let me try. You are shooting in Manual mode - right. What it means is that you set the Aperture, the Shutter Speed and ISO - the camera does NOTHING for you. BUT you are using the camera's light meter to get the light level reading. This all has NOTHING to do with how or where you focus. So let's look at a concrete example. In Manual mode, you are shooting a landscape scenery with the sky, hills and a lake in foreground and you want to focus on a boat tied to a tree in front of you. Now, you set your shutter speed at say 1/200 -it will stay that way - you are in manual mode. You set your ISO at 100 - you are in manual mode, it will stay that way. Now, you aim at the sky and using the light meter (in the view finder) you adjust your F-Stop to be correct pointing at the sky. Say, you set it at F16 - and the little bar in the light meter is correct at the center (0 ev point). You have the correct exposure - you are in manual mode - it will stay that way. There's no exposure to "lock in" - it will just stay that way - you are in Manual Mode - the camera will NOT change any settings for you! Now, recompose, aim at the boat and now focus - doesn't matter what focus mode you use - the exposure you have set will NOT change -the sky will still be correctly exposed, the hill a bit darker and body of water probably correct. If you notice the light meter reading when you aim at the boat, it may indicate that you are not correctly expose - but it does nothing to the camera's setting - you set it to ISO 100, Shutter 200 and F16 - it will stay that way and you snap the picture with those parameters - regardless of what the light meter read - YOU ARE IN MANUAL Mode. In Manual Mode, the light meter tell YOU what you exposure is - over or under but it does NOTHING to change the camera's setting - so you can recompose, re-focus all you want and the image will be shot at whatever settings you have set. You set it based on light reading of the sky and it will be exposed as such. Hope that makes sense. [/QUOTE]
