Developing Polaroid film involves a self-contained chemical process that happens after the picture is taken and ejected from the camera. You don't actively develop it in a darkroom like traditional film. Here's how the process works:
-
Ejection: The Polaroid camera ejects the photograph after you take the picture.
-
Development Starts Automatically: As the photo is ejected, it passes through rollers inside the camera. These rollers spread a reagent (a chemical developer) between the negative and the positive receiving sheet within the photo.
-
Protect From Light (Initially): Immediately after ejection, protect the photo from bright light. This is especially crucial for the first few minutes. Keeping it in your pocket, placing it face down on a clean, dry surface, or using a Polaroid film shield are all effective methods. This protects the film from overexposure during the initial development.
-
Keep it Warm (Optional, but Recommended): Warmer temperatures generally help with faster and more consistent development. Keeping the photo warm (but not excessively hot) can improve the final result. Your pocket works well for this.
-
Wait: The development process takes about 10-15 minutes for color Polaroid film. Some black and white films may develop faster.
-
Do Not Shake: Contrary to popular belief and old movies, shaking a Polaroid picture does not make it develop faster or better. In fact, it can damage the delicate chemical process and potentially lead to uneven development or other issues.
-
Observe: As the picture develops, you'll see the image gradually appear. Avoid touching the surface of the photo during this time.
-
Final Result: After the development time has elapsed, your Polaroid photo is ready!
In summary, the Polaroid film development process is largely automatic. Your main role is to protect the ejected photo from light and, optionally, keep it warm while it develops.
