Reversing a Photograph 
Reverse Print
Create a Reverse/Inverted Image in a variety of ways:
To create a Reverse/Inverted image you must first create a positive image with the best clarity and contrast you can. Take the completed image and put atop a Test Strip and cover with a cleaned piece of glass to form a tight contact. Create a Variable Timed Test Strip, using a reasonably high Filter (3+-5) and analyze which time best reflects a full/complete range of value from Black to White. Now take a light sensitive piece of paper and create a full size Inverted image. Notice that the Blacks become White and the Whites become Black. Your Spooky image is now ready to turn in along with the original.
You can also create an inverted Reverse image using Adobe Photoshop. If you select all you can click on Invert and your image will transform into a Reverse image.
