I know this has been covered on here before, but can't find the thread - AND didn't quite get it anyway.
Someone just posted in the gallery a 100% crop picture. What does that mean? :h?:
To me if I were to 100% crop a photo, all would be taken away, ie when I crop I am deleting some of the photo, so would not a 100% crop delete everything? I'm sure there is a good explanation, and I will probably look a fool (not uncommon) for asking!|:$|
 
I think as we found out before that this is open to interpretation. There was quite a debate as to whether the term should be used at all.

For me it means a crop from a full sized image without any resizing. On my 20D a full sized image is 3504x2336 pixels so a crop of 800x600 pixels of that image for web use with no resizing would be 100% - i.e actuals pxels from the full frame. Most often I crop to something like 1600x1200 and resize to 800x600, but occasionally with distant subjects they're so small in the frame that a straight 800x600 crop is all I can do.

Here's the main thread where it's been discussed previously if you want to peruse - http://www.birdforum.net/showthread.php?t=92172
 
Lisa, I am not totally sure whether this is right. The way I try to get a 100% crop for the web is to zoom in to the photo until it says 100% or 1.1 then use the marque tool to pick 800 pixels on the longest side and move the box to get the frame I want and then just crop, this gets rid of the unwanted bits I don't want. I think this is what people mean when they say a 100% crop.

Ian, thanks. What you said makes perfect sense and when I've done that I say I've resized the photo for the web - no cropping.
Christine - I also understand what you said. I do that all the time to get rid of the unwanted bits of the picture. Then I just say that I've cropped it, has never made sense to me to call that a 100% crop.
Sounds like the old saying - Different strokes for different folks.
