Turns out my very last statement was the most accurate.
Something SS or someone said in one of their posts jogged a mental gear a tooth or so, maybe more.

I just opened my PSE, loaded a photo and did crops in 12.5%, 25%, and 100%, saving each without resizing. Then looked at each crop and they appear to be EXACTLY the same. I locked the crop window to something like 800x600 just for grins and that crop box automatically adjusted its size to cover the exact same area (in proportion) in each different zoomed view.

So, it looks to me like as long as you haven't resized your photo from whatever came from your camera, then any crop taken from that photo in PP will be a 100% crop. And, I think I'm still relatively correct in saying this establishes a common reference point in letting us compare photos (and maybe cameras, lenses, sensors, and such?).

Now, is that an accurate assessment and statement?

Nope. Not if I understood what I read. The 100% tag means you cropped it from a photo that was at 100% size in your PP software. If you crop it from any other size in PP, then it would be a __% crop. A crop out of a 50% sized photo would be a 50% crop; a crop out of a 25% sized photo would be a 25% crop. I've never seen any references to any size crop other than 100% though, so that must be the common reference point in letting us compare photos.

Now, you guys who know this stuff backwards and forwards, how accurate is that statement? Hollar quick before someone sees my answer and starts quoting it as if I know something. Which I don't.

Aw, he's just resting on his face. Totally relaxed. Prolly the quickest way to regain energy.

Wow, this is one that really needs to be seen in the download to appreciate how well you focused on the face. I never think of birds as having nostrils but this little guy makes it obvious.

Very nice shot.

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. :)

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.

What the h... does that mean?

totally agree :thumbup:

Over here that's a red-breasted nuthatch. Excellent shot.

For sure no one is going to argue with your title. That certainly falls into the category of "fixer upper", or maybe more appropriately, "money pit".

Whatever, you got a nice shot.
ron

Luck, good timing, super focusing, great PP - all made a terrific shot. Congratulations.

ron

I just returned home from getting the patch off my second eye after the same surgery. I know exactly what you're saying about the yellow tinge that wasn't noticed before. The nice thing is getting the second eye done takes care of that problem. Love it, love it, love it...

ron

Well, aren't you the party pooper.

thankie,

Thanks.
