I really love my Nikon D90 DSLR camera for a multitude of reasons. Here is just one: white balance.
I was shooting the progress of the headboard I'm building in my wood shop. I snapped the pic on top and noticed how "green" it was on the camera's rear LCD screen. (Common effect of fluorescent lights.)
So I clicked into the white balance menu & selected the "fluorescent light" icon. From there it gave me SEVEN kinds of fluorescents to choose from. I selected "cool white" and snapped the bottom pic.
No need to fix it in editing--the in-camera white balance controls do it--love it!
Rock on Nikon ;-)
