Photography is all about the light. We all know that without light we would not have photography, or any other visual sensation for that matter. In photography, sometimes we fall short of having enough or the right amount of light. So this is when post processing gives me the opportunity to correct my photo, and give it the light I was envisioning when I took the picture.
The photos above are an example of putting my vision into effect. The top photo (original), was taken around mid-day. The sign was on the north side of the building in the shadows. When I saw this sign with the spot light fixture above it, my mind saw this light on at night, and shining on the sign. I knew I could re-create the look without having to go back at night to re-shoot the image. So, in my post processing I sent the image to photoshop and strategically placed the light where I had envisioned it, (bottom photo).
This is a fairly simple technique, yet can add a little drama to an otherwise plain image. Learning a few simple photoshop techniques can help in giving your images more sparkle and life. Try it.
