The highlighting brings such a delicacy to this petunia, yet the dark defined
veins that run through it signifies strength to survive in its elements.  the negative space
of dark value really makes the flower stand out as the focal point.

This is a wonderful example of contrast between lights and darks
as well as textures of smooth and rough, yet ,this image gives
me a feeling of balance.  the dark values cover one side and the
light values cover the other side.  There is also a great mixture of
values throughout the photo too.

I felt like a detective when I was playing with the values. I didn't notice while I was taking the picture that there
was a hidden message on the house. I believe is says, "HOME GROWN".
Working with black and white photographs really made me focus on the  details
which I normally wouldn't have noticed necessarily in color
