You can download my image if you'd like to follow along with the same image. I took this photo while experimenting with the macro mode on my newest camera. I never saw the tiny spider on the flower until I viewed the photo on my computer.
In your layers palette, right click on the background layer and choose "convert to smart object." This will allow you to perform non-destructive editing on the layer and make it easier if you need to edit the image after creating the detail view. If you're using an older version of Photoshop that doesn't have Smart Objects support, convert the background to a layer instead of a smart object.
Double click the layer name and rename it "original."
If you need to edit the photo:
Right click the smart layer and choose "edit contents." A dialog box with some information about working with smart object will appear. Read it and click OK.Now your layer will open in a new window. Perform any necessary corrections on the image in this new window. Close the window for the smart object and answer yes when prompted to save.
