My image scanning process in detail...
My image scanning process in detail: I rely on a meticulous yet simple and time-efficient scanning process to achieve the "3D Look," transforming flat film negatives into dynamic, immersive compositions without ever using scanners.
With a Sony NEX-7 camera paired with an enlarger lens, I capture scans with exceptional sharpness and detail, preserving the depth cues—bold shadows, rich textures, and perspective lines—that define my signature style.
The enlarger lens is critical, as its optical quality minimizes distortion and enhances clarity, ensuring the scanned image retains the three-dimensional effect intended in the original capture. This approach, rooted in applying drawing techniques, makes images appear to pop out or draw inward, captivating the viewer's eye.
Lens selection for capturing and scanning is crucial to maintain or accentuate the illusion...
While camera lens choice is a matter of personal preference, the lens used for scanning and digitizing film is critical to preserving the "3D Look." I’ve moved away from macro and normal lenses, opting instead for professional-grade enlarger lenses paired with an extension tube and a Sony NEX-7. Here’s why this combination excels:
Why Enlarger Lenses Defeat Film Flatness
Enlarger lenses, designed for darkroom printing, are optimized for flat-field correction and exceptional sharpness across the entire frame.
Unlike macro lenses, which prioritize close-up detail but can introduce slight distortions or softness at the edges, enlarger lenses deliver uniform clarity and micro-contrast. This minimizes the "flatness" often seen in digitized film, preserving the depth and texture that contribute to the 3D effect.
Why the Sony NEX-7’s 24MP Sensor is Ideal
The Sony NEX-7’s 24-megapixel APS-C sensor strikes the perfect balance for film digitization. It captures every nuance of the film grain and micro-details without overwhelming file sizes. Higher resolutions, like 100MP, are overkill for most film formats (35mm or medium format), as they exceed the film’s inherent resolution and amplify noise or imperfections without adding meaningful detail. The NEX-7’s sensor, paired with an enlarger lens, ensures that the digitized image retains the film’s tactile, three-dimensional quality.
My Top Lens Choices
After testing numerous options, two enlarger lenses stand out for their ability to elevate digitized film to the next level. These are cost-effective gems if you can find them:
1] Schneider-Kreuznach Componon 50mm f/2.8 Enlarger Lens
Renowned for its razor-sharp resolution and high contrast, this lens excels at pulling out fine details and maintaining edge-to-edge clarity.
2] Minolta 50mm f/2.8 C.E. Rokkor Enlarger Lens
A lesser-known but equally impressive option, this lens delivers exceptional micro-contrast and a natural rendering of textures.
These lenses, when paired with an extension tube and the Sony NEX-7, create a scanning setup that defeats film flatness, pulls in micro-details, and brings out that unmistakable POP that defines my work.
This combination ensures that the digitized image mirrors the depth and dimensionality of the original negative, making it a cornerstone of my process.

Why Enlarger Lenses Defeat Film Flatness
Enlarger lenses are engineered for darkroom printing, where they project a film negative onto a flat surface with exceptional clarity and minimal distortion. One might assume this flat-field design would produce a "flat" 2D image when digitizing film, but in practice, these lenses enhance the three-dimensional characteristics of scanned film due to their unique optical properties:
1. Flat-Field Correction and Edge-to-Edge Sharpness: Enlarger lenses maintain uniform focus and sharpness across the entire image plane, unlike many macro lenses that may exhibit edge softness. This ensures that every detail in the film negative—grain structure, texture, and tonal variations—is captured with precision, contributing to a tactile, three-dimensional surface.
2. High Micro-Contrast: Lenses like the Schneider-Kreuznach Componon or Minolta C.E. Rokkor deliver superior micro-contrast, resolving fine transitions between light and dark areas. This enhances tonal gradients and texture, making objects appear to "pop" against the background.
3. Minimal Chromatic Aberration and Distortion: With corrections for chromatic aberrations and geometric distortions, enlarger lenses preserve depth cues like perspective lines and shadow falloff, enhancing the illusion of three-dimensionality.
4. Optimal Aperture Performance: Performing best at mid-range apertures (e.g., f/5.6 or f/8), these lenses capture the film’s full dynamic range, preserving subtle tonal shifts that give images a lifelike quality.
5. Lens Structure and Refraction: The multi-element, symmetrical design of enlarger lenses minimizes spherical aberrations and ensures uniform light transmission, amplifying the film’s depth cues like grain structure and tonal separation.
