Title: 100% Crop
Post by: bmpress on June 25, 2009, 10:16:21 AM
How does one make sure that you are looking at a 100% crop on the monitor?

In most image editors you simply select 100% zoom.

100% means that one pixel in the image corresponds exactly to one pixel in the display. At less then 100% more than one image pixel is condensed into one display pixel. At more than 100% each image pixel is expanded into more than 1 display pixel.

Generally - which software? - a less than 100% crop will have scroll bars while the 100% crop won't.

Thanks...I guess what is confusing me is that some pictures have different image sizes and a 100% zoom on one will be a larger section on the other.

What do you want to see here?  To my ears a 100% crop is the full image on screen, with the scaling somewhat arbitrary in order to fit your screen dimensions.

But in your last message, you seem to be asking about looking at the pixels 1:1, the image scaled such that each pixel on the screen corresponds to a pixel in the image.

In any case, your software should have a menu command to do either of these, or even a key-combination "shortcut" that can get you there in a keypress.
