It appears that in this blog feature i can upload only one image per entry. Therefore I will have to make this in four parts.
The third picture is a screenshot after making what I would consider to be the basic, and essential adjustment to any image. By clicking-dragging the black, lefthand arrow over to where the histogram begins (at level 46) I have adjusted the black point from where there are no pixels to the level of the darkest pixels.
Doing similarly with the white arrow, by dragging it to the left where the histogram ends, I have adjusted the white point from where there are no pixels to the level of the lightest pixels in the image (level 218).
