100% crop?

I see this a lot in posts of photos to show sharpness and detail. Would someone mind defining what it actually means? Does it mean cropping a small section, and NOT resizing it?

That is exactly it, cropping a small section of your image while it is at 100%

By "100%" is meant that the cropped area shows pixels at a one-to-one relationship between image sensor pixels and screen display pixels. Hope you don't mind this small clarification, Buddha!

I'm confussed again, Chris. Your explination appears to be different to Buddhas.

Ok, 100% crop means that the section cropped is at 100% size of what shows on screen when picture is viewed at 100% magnification in your photo software.

Normally, pics are displayed at 72 dpi. (72 dots/pixels per inch), so that means, that a 3000 x 2000 pixel photo (roughly 6 Megapixel), if you have a big enough screen, it will show at 71.5 x 27.5 inches. So a 100% crop, is a section of that picture at that size.

Now, consider this. At 72 dpi is only good for "screen". For printing purposes (minilab or your own printer) you need at least 200 dpi. For commercial use, you need at least 300 dpi. The same picture at 300 dpi, will have a size of 10 x 6.66 inches.

Hope this doesn't scramble things more.

no, it is the same.

what buddha was trying to say is that you first take your image and view at "actual pixels" (at least in photoshop this is the command)

regardless of your monitor/resolution size you will now see the image at a one to one ratio of image pixels vs monitor pixels.

you THEN crop a section of that "actual pixel image" and post it here on the net.
