I know, it sounds crazy, but Preview actually has some pretty decent image-editing controls (very much like iPhoto's new image-editing controls, except believe it or not, Preview lets you set custom White and Black Points, whereas iPhoto doesn't). To unlock the photo-editing power of Preview, just go under Preview's Tools menu and choose Image Correction, which brings up a floating palette. Here are a couple of tips on correcting your images: The Gamma slider controls the midtones, and dragging it to the left brightens the midtones. To make a black-and-white image, drag the Saturation slider all the way to the left, then drag the Contrast slider to the right. |
