Could someone please explain exactly what 100% crop means? I did a search & find it mentioned many times but no basic explaination. Thanks!

Basically, it's a section of the original image that has not been downsized.

If you tried to post a full resolution image from most cameras, it would be very large on screen, requiring a user to scroll up and down, and left and right to see the entire image.

By cropping out a small section of it (for example, 640 x 480 pixels), you can show someone the quality of the full size image by posting that section (since it has not been downsized or resampled), without the drawbacks associated with a larger image (which wouldn't fit on most screens).

JimC, sorry for my dullness, but here's how I understand what you are saying:

Take a raw image, convert it to JPG, then crop a small part while the image is at the original size? Thanks again.

Right. Make sure you don't have any resample boxes checked and don't try to resize it before you crop out a section of the image.

Showing 100% crops lets someone see detail that may not be visible in a downsized image, without the need to post a full size image.

The responses seem to ignore the question. The responses appear to address the general term "crop" and ignore the "100%". There are several possible definitions of 100% crop. I suspect that the definition is nebulous as used by most. I too would like a definitive answer.

I can't tell you for sure the mathmatics of a 100% crop, but in Picassa and I believe Photoshop too, you can zoom in and it will tell you what percent it is cropping. It appears to be about 10% of the original image, which would make the math pretty neat...

I answered it in the first sentence of my first post in this thread:

A section of an image is a crop. Because it's a section of the original image (without downsizing), it's a 100% crop.

Wow. I guess that makes my theory pure crop! So much for math. Live and learn... :idea:
