Film Development at Neptune Photo: What Happens to Your Roll
You've shot a roll of film — now what? Here's exactly what happens from the moment you drop it off at our Garden City lab to when you pick up your scans.
Film development at Neptune Photo is simple: drop your roll off at 731 Franklin Ave in Garden City, choose a scan size, and pick up your negatives and digital scans — about 3–5 business days for color (C-41). We process C-41, black & white, and E-6 slide film in-house. Here's exactly what happens to your roll at every step.
Step 1: Drop Off
Bring your roll to Neptune Photo at 731 Franklin Ave, Garden City, NY. We accept all standard 35mm and 120 format films. When you drop off, let us know:
- Film type: C-41 (color negative), B&W, or E-6 (slide film)
- Scan size: Small (social media), Medium (standard prints), or Large (enlargements)
- Any special instructions: Push/pull processing, border scans, etc.
We'll give you a receipt with your order number and expected pickup date. Current pricing and scan options are listed on our film development page.
Step 2: The Development Process
C-41 Color Negative (Kodak Gold, Ultramax, Portra, Fujifilm, etc.)
C-41 is the standardized process for all modern color negative films. The film goes through a series of chemical baths in precise sequence:
- Developer — Activates the silver halide crystals and forms the dye image
- Bleach — Converts silver back to a halide
- Fixer — Removes unexposed silver halides
- Stabilizer — Prepares the film for drying
The whole process takes about 45 minutes at controlled temperatures (typically 100°F / 38°C). Temperature control is critical — even a degree off can affect your colors.
Black & White
B&W film uses a different process: developer, stop bath, fixer, and wash. B&W development gives us more control over the final look — we can adjust the development time to alter contrast and grain characteristics.
E-6 Slide Film
Slide film (like Fujifilm Velvia or Provia) uses the most complex process and is the most sensitive to temperature and timing errors. It's also the format where you see the image directly on the film itself, not a negative.
Step 3: Drying
After chemical processing, the film hangs to dry in a temperature-controlled environment. Rushing this step or drying in a dusty area can leave marks on the film. We take care to dry film cleanly so your scans don't have unnecessary spots.
Step 4: Scanning
Dried film goes onto our scanners. We offer three scan sizes:
Small scans — Great for sharing on Instagram or viewing on your phone. Resolution is sufficient for social media but not for printing larger than 4x6.
Medium scans — Our most popular option. High enough resolution for printing up to 8x10 and sharp enough to crop into individual frames.
Large scans — Maximum resolution scans ideal for photographers who want to make large prints or do heavy post-processing.
Step 5: Delivery
When your order is ready, we'll notify you by text or email. You can pick up in-store (scans on a USB drive, negatives in sleeves) or receive a digital download link.

Tips for Getting the Best Scans
Store your film properly before developing. Unprocessed film should be kept cool and away from X-rays. Don't leave film in a hot car.
Expose correctly. Even the best scanner can't rescue a severely underexposed negative. When in doubt, expose one stop more — color negative film handles overexposure better than underexposure. Choosing the right film speed for your conditions helps too — see our film ISO guide.
Communicate special requests. If you've accidentally shot a roll at the wrong ISO or want a particular look, tell us when you drop off.
FAQ
How long does film development take?
C-41 color negative is 3–5 business days; black & white and E-6 slide film are 5–7. Rush next-business-day processing is available — call ahead.
Do you develop 120 medium format film?
Yes. We process both 35mm and 120 film in all three processes: C-41, black & white, and E-6.
Do I get my negatives back?
Yes — your negatives come back in sleeves along with your scans. Keep them; they're the highest-quality original of your photos.
Can you develop expired film?
Usually, yes. Old film loses sensitivity and shifts color depending on how it was stored, but most expired rolls still produce usable images. Mention it at drop-off.
Do I need an appointment to drop off film?
No — walk in any time during business hours, Monday–Saturday.
