In the days of digital photography people tend to equate the process of “Photoshopping” and image as altering the photograph in some way to make it better either by enhancing the photo’s color and hue, adding or subtracting objects, or generally creating something that did not exist when the image was captured.Yes, you can do all of that when you bring a photo in Photoshop or any other image editing software.
All of the photos on my web site have been run through Photoshop. My goal when I bring a photo into the editing software is to make the image on my computer screen look exactly as I remember the moment when I depressed the shutter release.
Camera sensors, like different kinds of film, react to different colors and light in their own way. A camera’s color profile, ISO setting, and other image settings can alter the way the sensor sees what is coming through the lens.
I set my camera on the Adobe RGB color setting that usually results in a fairly color-dull image. The color information is locked inside the image, and I use Photoshop to unlock that color and bring it to the screen or print.
