Hello again, and Happy Friday! Today we continue with another tool, which
will assist you in becoming the photographer you always wanted to be.
What’s that little
graph for?
If you preview your image and keep on pushing the info
button a little graph may come up. This
is called a histogram. I have to say I
just love this tool. I use this tool
more than my light meter. The basic
thing to understand about this tool is that it counts the colors of the pixel
in the images and represents it in a graph.
The ideal histogram will look like a hill in which starts off low than
slowly goes up somewhere in the middle, then comes down before the end of the graph
(good tonal range). If that hill or
peek is not in the center but push to the left or to the right and is missing
part of it, than you are losing detail in your highlights (move to the right)
shadow (move to the left). If you see
big gaps so that you have two peeks, this means that you are losing part of
your tonal range. This tool will
prevent the photographer from going out and Photographing something then
getting home to realize that your subject is loses in the highlights or shadow
areas. The small screen on the back of
your camera is sometimes too small to view your image to realize this. It is only apparent once you get home and
view it on your computer screen.
Next week, I will discuss Tip Number Four. Have a great weekend and take some photographs.
