Photo Apps for the Mac (sans Adobe)

My intent is to provide descriptions of photo/image applications other than those offered by Adobe, e.g., Lightroom and Photoshop, so that an experienced Mac user can determine what the application is for and how to use it. I have intentionally left out descriptions of Apple's Photo and Preview applications as well. The book is not a review of applications that you may find on the internet.The scope of the book is limited to those image and photo apps that I have. Some I use frequently and others infrequently if at all. I will also mention other applications that I do not have but have similar functionality of the applications being described. I also directly quote Wikipedia and applications' websites and manuals when I feel that the quote is superior to my writing about the topic.Users should be familiar with image and photography application user interfaces as I do not explain what a jpg is, cropping, layers, etc. The focus here is on what a particular application does so that you can decide if you need it for your photo/image work.The 37 applications described are grouped into four sections: Image Viewers, Managers, and Organizers; Image Editors; Special and Single Purpose Image Editors; and High Dynamic Range Applications.
