I am new to the D7000. When I zoom in using the Zoom button ( bottom left) of the monitor and wish to retain the' zoomed in' image that I have just taken, how do I go about doing this? I use I Photo on my Mac and this also lets me zoom in but I have not figured out a way of retaining the image. I can crop and brush etc and retain the alterations but not the zoom feature. I don't have Photoshop - is there a feature there that I could use? Thanks for any help.
