#10. "RE: metering multiple areas without moving focus question"
In response to In response to 9

The dynamic range of the D7000 is really impressive at low ISO where landscapes are normally taken. But even with the extended DR, a scene with dark shadows and bright highlights exceed the range of light intensity that the camera or any camera can record.
So taking the photo, using the light meter built in will concentrate on getting the mid tones right with the extremes of dark and light might be lost due to clipping in the highs and dark shadows containing so little data that they are black, also representing lost data.
The D7000 shot at low ISO and in RAW format preserves more data at the high and low ranges than any other DX camera so even when shadows appear to be black, they contain recoverable data. The data can be recovered by adding gain or shifting the digitial numerical data up in value for values below some threshold you set when using the sliders in programs like Lightroom.
So, exposing to the brightest portion of the scene, and not middle grey like the meter is trying to do, you assure that the high tones are not clipped and skies and sunsets retain all the data possible. That results in an image displayed on your screen that is very dark in what appears to your eye as merely shadows. Download that file to your computer and using LR or any of the other editing software that can dislay RAW files. Now, you can adjust the gain, or brightness of the deep blackened shadows with shadow and exposure controls. Exposure controls all ranges but the shadow recovery section allows increasing the level of the deep shadows to they return to their normal appearance when viewed at the time of capture by your eye. Up tp about 4 stops of shadow recovery is possible without adding much noise. White Balance will also have to be adjusted or set to automatically adjust WB when importing a new image.
You can get the same sort of selective exposure adjustment by using a Graduated Neutural Density filter that allows more light loss at the top of the frame so the highlights are not too strong to capture all the detail and tone range. But the above method works well without any new gear to buy.
