Chris says that sometimes you need to "heal" an image to make the image better. The cloning brush in Photoshop, Lightroom, or any other photo editing app is ideal for healing areas of a subject you'd rather not be there. The cloning tool uses pixels from another part of the image, and clones it to the destination. But it's best used sparingly. There is also a healing brush, which will adjust the color and brightness of the cloned pixel, to that of the destination. If you hold down the shift key, the edge gets feathered. And it's non destructive if you don't like it. You can either undo it, or move it around. You can even do it on your mobile device with an app called SnapSeed.
A few other tricks: Take out something, like a wire. You can drag the healing cursor to make a selection and then remove it. Click on the beginning, and then with the shift key pressed, click on the end. It'll create a complete line of selection. Lightroom has another tool called "visualize spots" which enables you to remove dust bunnies by enhancing hard to see spots and then you can remove them.
Don't forget our current assignment - "eyes". Take a photo of, about or otherwise concerning the concept of "eyes" and then post it to the Tech Guy Group on Flickr. Make sure to tag it with the word "eyes" as well! And if Chris likes it, it could end up on next month's photo contest review segment!
