And then there is option #3 which I use; Disregarding any really deep technical stuff:
My monitor is 1920x1080. I view my shots in a window not full screen. That window shows the full frame as being at 22% zoom level which I equate to percentage of actual size. I assume that if I zoom in to 50% then the portion of the shot I see is 50% actual size. So I say I cropped at 50%. This completely ignores how much I threw away or kept. I am assuming a one to one correspondence for picture pixels mapped to screen pixels when viewed at 100% which may not be a reality. Works for me anyway.
This is not what is was asking about, and your option #3 will not help me. When I see a shot posted here, the poster says it is cropped 70 percent, I want to know how big the remaining image occupied on the uncropped image. Wiki, as somebody wrote here, says one thing. Some people here use the opposite meaning. I guess I will have to ask this question every time I see a posting and want to know what the original looked like.
