How to do a 100% crop in DPP

In Photoshop, use the crop tool. Make sure the "Resolution" window is empty and that the "Front Image" button is not clicked.

Then crop, and you'll have a 100% crop. If you want a particular aspect ratio, enter it in the width and height windows in inches (not pixels).

Heh! Peano, are you sure you are talking about at "100% crop" here? As in a crop of a small portion that will map 1 pixel of the image to 1 pixel of the monitor resolution in a way that will be viewable on the Web? Maybe I don't get your explanation?

A 100% crop is just a way of showing in a forum what you see on your monitor when you view an image at 100%, without making people have to look at a 3+ MB file.

To me both definitions essentially say "any crop of an original that has NOT been re-sized". (Different sized monitors notwithstanding.)

That is what I have always taken it to mean, anyway.

When you do/make/perform/execut​e/effect/[etc] the 100% crop you can have the picture displayed on your monitor at any practical size. The result will still contain the original, un-resized number of pixels. You can then zoom in/out and view the result larger or smaller as you wish.

Now don't all tell me I'm wrong and that it's hat-eating time.

In the 'old days' '100% crop' meant that the image was to be printed from the full frame (negative or slide) - so actually, no cropping at all. Took me a little while to make the transition to the new meaning after moving to digital and joining the digital discussion forums.

Yes, he is.

Hehehehe. Know what you mean

I want just to give a complementary tip to this tutorial.
If you want an exact crop, say 800*600, just choose the 4:3 ratio and then just draw any small crop, and then write directly 800 in the Width edit box.
When you'll move the cursor to the Height edit box, the cropping area will be updated automatically and the value 600 will be calculated automatically too.
Then if you want you can move your crop area to adjust its position as you want.

Sounds like you might need a little refresher on the meaning of "100% crop."

I think it's because I'm not using CS5. Of course the OP was asking about DPP and so nothing is quite the same there!

Works the same in CS4, CS3, CS2, CS ...

Sounds like, as long as you don't resize/resample, it's 100%. Is that about it?

Exactly.

I guess I should say I'm used to using Lightroom and occasionally DPP and not using PS for such things!

Seems like the other thing to set to zero is noise reduction, third tab on the tool pallet. DPP defaults to camera settings which are more than zero. I took some test shots on my CF card with a 7D in BestBuy and when I opened them with DPP the settings were something like 14 and 8 which are quite high. If you want, this default can be changed on Tools/Preferences/Tool Pallet/Default Noise Reduction Settings. Seems to me that around here many people think they are posting 100% crops with what they think are zero noise reduction, but in actuality DPP is applying NR to their RAW image.

That's a good observation, Dave -- I'll have to be more observant of that -- I do a lot of lower light high ISO shooting so NR tends to be a way of life, but I should check that for good light/low ISO shots and see how much of a difference it makes. I do my "serious" processing in Lightroom but play with DPP enough to want to get the most out of it...

It might just be me not knowing what I was doing with the 7D but with all the discussion on the low noise at high ISO settings of the 7D, I took a few test shots in the store at 12800 ISO and I was real surprised the camera defaulted to NR of 8 and 14. I was considering the 7D for night and indoor sports but after seeing the defaults I decided to stick with the 1DmII for now. I can crank up the NR if I want a soft image.
Here is a screen cap of all zeros and the 7D default 8 and 14. Is there a 7D menu setting to change this?
