[QUOTE="OBXGuide, post: 1565522, member: 31770"] Okay Terry, I will add to what Roy and Tim said, maybe in a different way. You will need to open the attached screen shot to follow along. This is a screen shot of image editing software with a photo of a gray catbird loaded. On the left is the original image (call it image #1) that measures 4762x3768 pixels outside dimensions, as indicated by the arrows. Now, let's say you highlighted the area of this image indicated by the red box with your crop selection tool and chose "CROP" from your menu, then saved the resulting image, you would get a file as shown in the right window. We'll call this image #2. Image #2 measures 2564x1908 as indicated by the arrows on the right image. Okay, what you have here is a 100% crop. Image #2 is a 100% crop of image #1. WHY? Because as you can see, the bird in image#2 is the same size as the bird in image#1. You have cropped the image, but you left the resulting cropped area unchanged. All you did was CUT AWAY or "CROP" out the unwanted part. That is the "crop" part. You left the bird the same size, and that is the "100%" part, thus a "100% crop". IF you then took image#2 and RESIZED it to 1024x762 pixels in order for it to be an acceptable size for posting here and saved it as image#3, then it would no longer be a "100% crop" of the original (image#1) because what is depicted INSIDE the image is no longer the same size as the original data. It's now smaller than what was depicted inside the original image. I hope this helps demystify this understandably confusing concept. (Sorry Tim, I know this is getting away from your original post topic) [/QUOTE]
