Film Developing FAQ – Guelph Foto Source 


Welcome to the Film Developing FAQ from Guelph Foto Source. Whether you’re new to analog photography or a longtime film shooter, we’re here to help you understand the process and make the most of your film. From 35mm to medium format, color to black & white, we provide professional film developing, scanning, and printing services in Guelph and across Canada. 

  • 1. What types of film do you develop?

    At Guelph Foto Source, we process 35mm, 120 (medium format), and disposable cameras. We handle color negative (C-41), black & white films. If you’re unsure which type you have, just ask—we’ll guide you. 

  • 2. How long does developing take?

    • Color film (C-41): 6-7 business days 
    • Black & white film: 10-14 business days 

    Rush service may be available—contact us for details. 

  • 3. Do you offer film scanning and digital files?

    Yes. We can scan your film to JPEG or TIFF formats in standard or high resolution. Files can be delivered via FILM CLUB , USB drive, or CD—perfect for archiving or sharing online. 

  • 4. Can you make prints from my film?

    Absolutely. We offer professional-quality prints in multiple sizes, from standard 4x6 to enlargements. Prints can be made directly from negatives or from digital scans. 

  • 5. Do you develop disposable cameras?

    Yes—we process all major disposable and single-use cameras. Drop them off in-store or mail them in for easy developing. 

  • 6. Can I mail my film to Guelph Foto Source?

    Yes! Many of our customers mail their film to us for processing. Simply package your rolls securely, include your contact information and order preferences, and ship them to our store. We’ll send your scans digitally and return your negatives by mail. 

  • 7. Will I get my negatives back?

    Yes—your negatives are returned to you at a cost, unless you specifically request otherwise. 

  • 8. What about expired film?

    We develop expired film, though results can vary. Expired rolls may show color shifts, grain, or lower contrast, but often this adds unique character to your photos. 

  • 9. How should I store my film before sending it?

    Keep your film in a cool, dry place. Refrigeration is best for long-term storage (but never freeze your film). Avoid leaving rolls in hot cars or direct sunlight. 

  • 10. What if my film comes out blank?

    If your roll is blank due to underexposure, expired stock, or a camera issue, we’ll let you know. You won’t be charged for scans or prints on blank rolls. There is a small charge for blank roll developing as we have chemical and labor costs  

At Guelph Foto Source, we’re passionate about keeping film photography alive. Whether you’re local to Guelph or mailing in your film from anywhere in Canada, we’re here to help you capture and preserve your memories.
