Conclusion
After completing all the steps above, close the lens to the camera. Re-insert the battery into the camera, and add in a test roll of film as well. Turn on the camera and shoot a couple photos in order to see if the light seal is working correctly.
After completing all steps detailed above, replace the lens by completing step 3 backwards. Once shooting with the fix, high contrast photos are a good way to test the light seal placement. If there are any remaining light leaks, inspect your foam placement and gently press down each foam strip to maintain full contact in the crevices. Over time, check your light seals during routine cleaning—especially if the camera has been stored in heat or humidity.
