100% Crop, How To Do In Photoshop CS

Eddie Gonzalez , Jun 12, 2005; 10:04 a.m.

What is the definition of a " 100% " crop? How do I make a 100% crop in Photoshop CS? This is my first attempt but it turned out to be a 4x4 inch file that is 2348x2348 pixels. It's a cut out from a 20D raw file.

Hi Eddie, Just zoom in to 100% by pressing CTL-ALT-0 (that's a zero, not the letter "O") then drag the crop tool over what you want to see (or show) and press enter. That's it! Good luck . . .

no need to zoom in all the way - just simply take your straight scan/digital camera file and crop.

that's it.

a 100% crop is simply a crop of a section of a photo at it's original (i.e., 100%) resolution, without any resizing/resampling, usually to show how well (or poorly) a particular camera or scanner works.

In printing a 75 percent crop means 3/4 the input image is not used A 90 percent crop means 9/10 is not used; 1/10 printed. Thus a 100 percent crop would be nothing printed; ie nonsense.

<ctrl> <alt> "zero" will push your image frame out to fill the available space in the Photoshop window, either with or height, so that 100% of the image is visible. Subsequent <ctrl> <alt> "+" key combos will further push the image frame out to fill the other direction, and increase the zoom in steps. A few of these latter key combos will bring you to be 100% zoomed in.

It usually refers to pixel-for-pixel imaging, e.g. the picture on the screen is full size. One pixel from the camera is represented by 1 pixel on the screen.

Omitting the <alt> will leave the image window as-is, just doing the zoom. Replacing "+" with "-" will... (you know where this is going)

It's interesting to consider the difference between Kelly's language and the other answers. It seems to have become common usage for a "100% crop" to mean the whole image - essentially, an "uncropped image" and a "100% crop" would mean the same thing in that case. Nonsensical, perhaps.

Eddie Gonzalez , Jun 12, 2005; 09:36 p.m.

if Leszek is right, which he makes sense, then how would one achieve that 1 to 1 ratio? In Photoshop CS, you can change the PPI when you crop. So how does one determine what the PPI should be at when croping (to ensure a 1 to 1 pixel ratio)?
