I've read many posts talking about "at 100% crop" and have been uncertain how "enlarged" that makes the image or how "tight" that makes the crop. I can click the zom+ button on my D7100 8 times to zoom in on my camera display - is 4 clicks 100% cropped? Please clear this up for me - I'm sure the answer is as plain as the nose on my face 😳. Thanks.

100% crop means that you should not resize your image to show the whole image capture ....instead you crop a section of the image so that one pixel from the image maps to one pixel in the screen

When I post a detail cropped with no magnification of contraction I use 1:1 crop as description when other use 100% crop...

I find the 100% description misleading in my opinion.

Jerry, Kumaran is accurate but more importantly is that when you view a true 100% crop, and you do view at 1px:1px level, there is NO distortion from the computer. At anything less or more, the screen if you are on "fill the screen" mode, the computer has to "interpolate" the data, which means it has to compensate by adding pixels or taking away pixels as it sees best, which is no longer a 100% true rendition of the image, as it has been altered in much the same way as when you convert to a jpeg file but likely not as drastic as that. Hope this helps clarify why it's important! ;-)

I agree. 1:1 crop makes sense. To me a 100% crop should mean NO CROP it is 100% of the image as captured. The use of a percent to mean a 1:1 is just plain peculiar.

I mean, what does a percentage have to do with this at all?

I'm sorry, but there's not a single answer on this page that makes anything clear (except maybe the hotlink). You guys are either trying too hard or you just don't know how to simplify things so we peons can understand. Get rid of the gibberish. Say it without trying to impress us with the marvelousness of your knowledge.

Guess it's been so long since I became a mental midget that I can't even envision any mental giantness in my past. Must have gotten up on the wrong side this morning.

Thanks very much - I had thought it meant some percent of the original size rather than any level of zoom while retaining all the detail of the original. Since a JPEG is compressed from RAW, does it also hold true inasmuch as cropping a JPEG retains whatever detail a JPEG gets from the RAW file size?

I'm guessing here, but it probably means that you are filling 100% of your screen at 1:1. No more, no less! ;-)

I'm going to jump into the waters and try to add a productive post instead of the negatives I've managed thus far.

I did a search on this very question a week or so ago because I was also bumfuzzled by the term. Here's my take on what all the posts and hotlinks indicated (at least to me).

-First, envision being in some PP software and looking at a photo.
-Zoom that photo until it is at 100%.
-Now, do a crop of anything in that photo you wish at any size you wish. Doesn't matter.
-Do NOT resize the crop. Simply do a "Save As".
-You now have a crop out of a 100% sized photo. A 100% crop.

Ok, now I'll see how accurate my interpretation is of what all I read.
Sic 'em, guys. :)

Basicly, if your picture is un-cropped, it is a 100% crop ...., then again it's not a crop if it's 100% of the original picture. Who's on first ......

So it is just a crop without resizing. In short it is just a crop. The added 100% tag is just superfluous.
