When working in Photoshop (elements) most of us know to save the image in a PSD format if we ever want to continue editing the image where we left off. The layer will appear nicely arranged on the right hand layers panel. But what if you have grouped layers, or even discovered the technique from a book or website? If you used an specific action to create the image, you may not remember the name of the action that you used especially if you have a long collection. What brush did you use with that image?
You could always use the text tool on the image, but there is a slightly more refined way of leaving yourself some additional breadcrumbs.
You will notice what appears to be a small pad of paper appears next to your cursor. When you click on your image, a pad and pencil appears along with a window opening up that allows you to enter a 'note'. In the above image, see the note icon left on the characters chest plate. You can add as many notes as you want to an image, or even change the color of the notes.
Right clicking on the note icon will give you the option to delete that note. This is a note within Photoshop, and if you save the image as a JPEG, the icon of the note will not appear in your saved image. This little feature is very simple, but can also save you a great deal of time when it comes to remembering specifics about a specific image.
