Grabbing a 700x700px 100% crop

This tutorial explains how to take a 100% crop of your image at the exact size of 700x700 pixels.  The illustrations here were taken in Photoshop CS5, but this method applies to all recent versions of Photoshop and Elements.

Often I'll ask you for a 700x700px 100% crop if we're discussing noise or focus or any small-detail problems in my Facebook group.

Of course, you can adapt these instructions for other sizes as well.

It's very simple.  When you're ready to take the screenshot, simply press M to choose your Marquee Tool:

(If the rectangle Marquee isn't selected by default, click and hold on the tool to get the little flyout menu, and choose it there.)

In the Options Bar, change the Style to "Fixed Size":

IMPORTANT: Make sure the "Feather" is 0 px.

Then enter "700px" in both the Width and Height fields:

(It's always a good idea to type the "px" part. If you don't, it might default to inches or something else.)

Single-click on your photo and the 700x700 marching ants box will appear. Then click in the middle of it to drag it to exactly where you want it:

Go to the Image menu and choose "Crop":

And there it is - your 700x700 piece of image:

Now save it as a jpeg, ready to upload to Facebook for me to see.
