I’ve been involved in photography a long time. Such a long time, in fact, that I can still remember using a darkroom to tweak a photo. Digital photos are so much easier to manipulate.
Like me, I’m sure you have many digital photos that look washed out, dull and flat. The colors aren’t what you remembered when you took the photo and photo just seems lifeless. Photoshop and other editing programs can help you render these kinds of photos into ones that you would be proud to show on your site.
Let me show you an example. The first photo is the original. The only thing I did was size it to fit this page. The second photo is this same photo manipulated in Photoshop. Which one do you like better?

Grand Canyon photo before Photoshop.

This same photo after a digital darkroom session.
This second photo is much more dramatic and the colors ‘pop’. All this was done with Photoshop. You can double click the photos to see a larger version.
