How do you compute a crop percentage? Do you compute it based on the final crop measurements (length x width) or based on the relative area cropped from the image?
I'm not sure if I was clear.
I mean, when I use the crop tool, I usually indicate the final image size I want, usually 1024 x 800 (based on Flickr free account). Cropping this way allows me to crop either a very small part or almost full frame of the image and still come up with 1024 x 800. Basing this on an initial image size of 4272 x 2848, it is a 7% crop.
The percent crop though becomes different if you base it on the area cropped against the whole image, ie, whether you took a small or a large part of the original image.
I am thinking that the percent crop is based on the relative area cropped from the image and not on the final size.
Another usage of the percent crop is 100% crop when referring to a pixel view of an image which has now an entirely different meaning.
So, what do you think?
