Selecting specific area using "cookie cutter"

[Ruth McDowell]

Hi all,
Could anyone point me to a plugin or feature of imagej that acts as sort of
a cookie cutter?

I want to analyze haphazardly chosen sections of photographs for brightness,
and I want the sections to be the same size each time. I can set the area
manually each time, but in the interest of efficiency, I am hoping there is
a way to somehow enter the area I want and "cookie cutter" out these
haphazardly chosen sections from multiple photos for analysis.

In addition, if anyone has used imagej to measure brightness and has any
advice or tips, please let me know.

I'm new to the list and wasn't sure what to search for in the archives, so
I'm sorry if this has been discussed before. Thanks for the help!

Hi Ruth,

Have you tried the Restore Selection command?  You can draw a
region of interest on one image, then click another image and
use Edit --> Selection --> Restore Selection (or keyboard
shortcut Cntl+Shift+E) to re-create the ROI on the new image.
 The new ROI can be dragged to a random area on the new image
if that's what you want.  

Image --> Duplicate (Cntl+Shift+D) will then pop the ROI out
of the image and into a new window without harming the
original image, allowing you to crop multiple ROIs from the
same image quickly.

Best,
Christine
