35mm-75MM Film Grading: The Industry’s First & Only.
Stop Hiding Your History. Grade Your Cinema.
The hobby is evolving. From the neon glow of Pokémon and the magic of Disney to the epic galaxies of Star Wars, collectors are rediscovering the beauty of authentic 35mm film. Whether you’ve acquired a full reel or have carefully hand-cut your favorite single frames, 2-cell pairings, or 5-to-7 cell strips—Collector’s Grade is the only grading service in the world that treats your film with the same professional rigor as a 1st Edition Holo.
We don’t just "encapsulate." We grade.
The Collector’s Grade Standard: What We Look For
Just like a high-end trading card, a film cell carries a "grade" that defines its history and value. Our experts put every frame under the lens to evaluate:
- The Edge Cut: Was it a clean, professional separation, or are there jagged edges?
- Surface Clarity: We hunt for surface scratches, "hairlines," and abrasions that distract from the image.
- Film Integrity: We check for "cinematic wear"—looking for wrinkles, creases, or "heat melting" from vintage projector jams.
- Color Preservation: We assess the vibrancy and condition of the emulsion to ensure the "soul" of the movie is still there.
Why Grade Your Film with CG?
1. The Only Game in Town
You won't find this at PSA. You won't find this at Beckett. Collector’s Grade is the pioneer. We are the only company with the specialized knowledge to officially grade and slab 35mm film frames.
2. Permanent Archival Protection
Film is organic and fragile. Exposure to oils from your skin, dust, and humidity can destroy a frame in years. Our slabs provide a rigid, archival-safe barrier that freezes that moment in time forever.
3. Museum-Quality Documentation
Our labels don’t just say "Film." We document the Year, the Movie, and the Specific Scene. Whether it's a German-language title card, a credit roll, or an iconic character close-up, your label will tell the world exactly what piece of history you own.
What We Accept:
- Single Frames: The perfect "card-sized" cinematic gem.
- 2,3 & 4 Cell Strips: Double the action, double the story.
- 5-to-7 Cell Strips: For those who want the full "motion" of the scene preserved,
For the People. For the History. For the Collector.
Don't let your film reels sit in a dark tin. Bring them into the light. Get them graded. Get them protected. Join the cinematic revolution only at Collector’s Grade
Please Note: 1,2,3 & 4 cell strips are standard size - 5-7 cell strips are Jumbo size

INSPECTING & CLEANING YOUR FILM BEFORE grading
FILM INSPECTING & CLEANING
I. Advanced Inspection Protocols
The "Raking Light" (see photo on the left) method you discovered is scientifically sound for detecting surface deformation. When light strikes a smooth surface at an acute angle, any deviation (like a scratch or a vinegar-induced bubble) casts a shadow or creates a highlight that is invisible under direct "transmitted" light.
1. Identifying Vinegar Syndrome (Chemical Decay)
Vinegar Syndrome is the autocatalytic decomposition of cellulose acetate film base.
- Early Detection: The first sign is often a faint vinegar odor (acetic acid). Professional archivists use A-D Strips (Acid-Detecting strips) to measure the level of acidity inside a container.
- Visual Cues: Look for "Spoking" (the film warps or twists), "Channeling" (bubbles forming between the emulsion and the base), or a white powder/crystalline deposit on the edges (Kemper & Herm, 2023).
- The "30% Rule": Research shows that lowering relative humidity to 30% RH significantly slows this degradation (Kemper & Herm, 2023).
2. High-Magnification Scratch Analysis
Using a 5x to 10x loupe under raking light allows you to determine the depth of a scratch:
- Base Scratches: These appear as indentations on the shiny side. They can often be hidden by "wet-gate" scanning or specialized fillers.
- Emulsion Scratches: These appear on the duller side. If the scratch has "plowed" through the silver or dye layer, it is permanent image loss.
II. The Archival Cleaning Toolkit
Using the wrong solvent can permanently "mottle" or streak the film by leaching out oil-soluble dyes (Society of Motion Picture and Television Engineers [SMPTE], 1999).
1. Approved Solvents
- Isopropyl Alcohol (99%): The "98% or higher" rule is critical because lower concentrations contain water, which can soften the gelatin emulsion and cause it to swell or stick.
- HFE-7200 / Novec 7200: This is the modern professional replacement for restricted chemicals like Perchloroethylene. It is non-flammable, dries instantly, and is safe for both base and emulsion.
- PEC-12: Highly effective for non-water-based stains (grease, adhesive residue) but should be used sparingly as it is a powerful solvent.
2. Forbidden Materials
- Cotton Balls/Swabs: These shed fibers that snag on the film's sprocket holes.
- Water-Based Cleaners: Never use "Windex" or water-diluted alcohols; water causes the emulsion to soften and can lead to permanent damage if the film is wound while damp.
- Mineral Oils: Avoid lubricants or oils as they can dissolve the film’s dyes (SMPTE, 1999).
III. Step-by-Step Archival Cleaning Procedure
- Environment: Work on a clean, dust-free surface. Ideally, use a light table but keep the light off during the initial wipe to prevent heat from accelerating solvent evaporation too quickly.
- Preliminary Air-Dust: Use a Bulb Blower or canned air (held upright) to remove loose grit. Wiping a film with grit on it is like using sandpaper.
- The "Cloud" Method: Apply the solvent to a PEC-PAD (not the film). The pad should be damp, not dripping.
- One-Way Swipe: Wipe the film in a single, continuous motion along the length of the strip. Do not scrub back and forth, as this can grind trapped dust into the cell.
- Quarantine: If you identify a cell with "vinegar" signs, do not use the same cleaning pad or gloves on healthy film. Acetic acid is "contagious"—it acts as a catalyst that accelerates decay in nearby healthy film (Kemper & Herm, 2023).
