The Screen Transfer Function
This might be a good time to mention another tool that is useful. While [ctrl]a is great for quick looks at the data, sometimes you want more control. The ScreenTransferFunction is used for this.

When using the ScreenTransferFunction, (and [ctrl]a, you are not actually changing the underlying data. What you are doing is changing how that data is presented on the screen. When using this, I almost always have the blue check mark on the bottom right clicked. This tells the screen transfer function to take on the settings of whatever image is selected. If you click the yellow and black icon that looks something like a radiation symbol, this will do on auto-strech of the data similar to hitting [ctrl]a. Moving sliders around will affect the results. The only other thing I want to mention here is that the symbol that looks like to links of chain is currently selected. This ties all channels together, when doing the stretching. This is important for RGB data. Sometimes you want to do the best stretch for each channel independently. To do that you would deselect that link icon.
Here are the autostretched results of the Dynamic Crop.
