Exposure:
-
Open the shutter for a brief moment, allowing light to hit the photosensitive surface. Start with exposures of about 5 to 10 seconds for pinhole cameras, adjusting based on your results.
-
Developing the Images:
- If you used film, follow correct developing techniques in a darkroom. If you used a digital sensor, connect to a computer for image processing.
Evaluating And Optimizing Results
After developing your photos, it’s crucial to evaluate the results critically.
- Analyze the Images:
-
Look at aspects of lighting, focus, and composition.
-
Make Adjustments:
- Based on your evaluation, tweak your shutter speed, focus, and aperture (if using a lens) for improved outcomes in future shots.
