If we have picture files and look at the histogram of the black to white scale, what code do I input. Let's say it goes from 2*10^-4 to 6*10^-4, what if I want to just see the pixels maybe, from 3*10^-4 and up? Thanks

You can use MATLAB Image Processing Toolbox function 'imhist' to create the histogram of black to white scale of your images. Refer to the following link for more information:

However, there is no pixel level range control except for the bin count.
