100% Crop

[audi321]

Hi all. Sorry to be dim, but I hear this term used a lot on here, and for those without Photoshop, could someone explain what it means?

I use GIMP on the Mac, so a tutorial would be nice! I've tried to Google it but I can't get a sensible answer, a lot of results suggest there isn't such a thing lol.

Thanks all.

Its a cropped image (not re-sized) where the image displayed on the internet is at the resolution it came out of the camera, therefore showing maximum detail.

Eg if you camera captures a 4000x3000 image, and you crop a section out at say 1000x1000 and then display this 1000x1000 image it is a smaller image but still at the resolution that it was captured.

Original Image resized to 800pixels wide



100% Cropped Image (800 pixel wide crop)

Also refers to purely arable farmers.

I've never understood this either! If you crop away 100% of the pic then surely there's nothing left?!

I've always thought of it as blowing the image up to the resolution at which it was captured, then cropping it to only see part of it?

There is actually a chance I may be partly responsible for this horrid expression. In 1996 (IIRC) might have been 95 or 97 - I won the Internet Digital Photographer of the year award. It wasn't a big deal as there were only about 35 and a dog of us doing it back then. The cameras were crap, as were the photos.... but during said award I had to explain how I'd done what I did (which was take 2 digital images and combine them). At the time I showed the judges a 100% crop as I called it... and they had no idea what I was talking about... but from that moment on, I saw the expression endlessly appear on forums.

I may have nicked it, but I don't think so. Hardly a Tim Berners-Lee moment, and I apologise if it was me... 'cos it's a bit crap.

As you were.

ETA... out of interest, it was sepia at the time (don't ask... okay, yes, because I could), but this was the image:

Actual or full-size crop might be better. In other words it's pixel for pixel (camera pixel and computer monitor pixel), and as that would be too big to fit on a monitor, you show only a small section of it.

The idea of '100%' probably comes from Photoshop, when you zoom in or out of an image and only at '100%' is it actual size.

Ah that explains why google doesn't really bring anything up. So it's showing an image at its full resolution that the camera has taken it at?

Anyone know how to do this in GIMP?

Not a GIMP user, but just zoom to 100% and then crop (shift C) a portion of the image.


FWIW it's normally used for technical reasons such as to show sharpness (or lack of it) in an image

It is used mostly because the majority of website forums have restrictions on image size that won't allow you to post an image at 100% resolution. To render detail at 100% for someone to view/appraise, it's necessary to crop a portion out of that image to a size that meets posting restrictions. The resulting crop is at 100% resolution, but only a small percentage of the complete image.
