Photographs do not lie. Well that was the original concept that no longer works today. In fact, more people mess around with the images taken from their cameras or now the cell phone(s). This book is made as a tool to how you may enhance/change a picture to meet your needs. I often during family annual functions or visits with friends, take a couple of pictures of a group, then have everyone sort of stay in one place, as I put myself in a blank spot (edge) and have my wife or someone just shoot 2-3 more exposures with me in it, that I later just move me into position, and hurray, a whole group shot. I look for anyone that looks bad, eyes closed, etc. and then just clone/change them to look their best.
It is also a great way to take old historic pictures, often faded, stained, torn, and manage to repair them, using the "cloning" tool to repeat portions of the original part of the photo. So, have fun with this book, just some tips and images that may entertain you, and how you may save some family pictures from yesteryear.
