Is this your film?
Start with the shape of the cartridge, spool, or envelope. Then check the label. Never open or unroll exposed film to identify it.
- A sealed roll marked 120 with slide, transparency, or reversal film on the wrapper.
- Common medium-format slide stocks are the Provia and Velvia families.
- A roll that says C-41 or black-and-white is not E-6 and goes through a different line.
Format and chemistry are different things.
120 is a format and E-6 is a reversal process. E-6 develops to a positive transparency rather than a negative. ECN-2 is a separate color process.
Old film, honestly
Film that has waited deserves an honest assessment before it goes into chemistry. Here is what we watch for.
- Transparencies keep color well in the dark but fade quickly when displayed.
- Old E-6 can lose shadow detail and shift toward magenta or cyan.
- Store slides cool, dry, and dark when they are not being viewed.
What to expect
The age and condition of your film affect the results.
- Correctly exposed medium-format slides are richly detailed when scanned.
- Slide film punishes underexposure and overexposure more than color negative.
- Scans show the transparency as it is, including any age it carries.
Then put one on the wall.
Phones are great. Walls are better.
Developing reveals the images on your film. Scans make them easy to share, and photographic prints make them something you can hold. You are not charged upfront for a guess at how many frames will turn out; print quantities and charges are based on your actual images.
If you add scans, the files are delivered digitally once your film is developed. Prints can be added at the same time or later; sizes and finishes are chosen in the builder, and the lab confirms the print charge. For 120, 220, and 620, both are separate choices from developing.

Questions we get
Do 120 slides come mounted?
Medium-format slides are not returned in 35mm-style mounts. They come as cut transparencies, ready to store or scan.
Can you print from a transparency?
Yes. Once developed and scanned, we can make photographic prints. Dense or thin slides may need more careful handling.
Is E-6 available in 220 and 620?
Tell us which roll you have. E-6 is available for 120; 220 and 620 need handling confirmation because they are less common.
Can I mail my film, or do I have to come in?
Both work. Start your order online first, then mail your film to the Quakertown lab at 308 W Broad St or drop it at either store: Quakertown, PA or Flemington, NJ. Include your order number with mailed film.
Is the price guide a final quote?
No. The developing chart and scan guide are guides, not a checkout quote. Your exact price depends on the format, process, and options you choose when you order. Scans, prints, shipping, and tax are additional where they apply.
