Answer 1

You have a 16bit gray level range but most of your values are at the lower end. Therefor everything looks dark.

You can either look at a smaller range of your values that acutally contains the visual info and cutt off the rest or you can alter your data like displaying the log of your data.. Another solution would be using a colour map. Make sure you understand why you hardly see anything here. Check out the histogram of your data and compare it to the histogram of a well visible image!
