Mastering Color Negative Scanning: Invert & Optimize in DxO PhotoLab 9
Diving into film photography often means dealing with the digital side—scanning negatives and converting them to positives. If you've ever scanned color film like Kodak Ektar 100 or Portra 400 and struggled with that stubborn orange mask or inconsistent colors, my latest YouTube tutorial is here to help. In the video, I walk through the process using DxO PhotoLab 9's scanned film optimization tools, from basic inversion to creating custom presets for batch processing. This companion blog post breaks it down further, with expanded tips and insights for film enthusiasts.

Why Scan and Invert Color Negatives?
Color negatives capture beautiful, vibrant images, but scanning them as positives often results in inverted colors dominated by an orange cast from the film's base layer. Tools like DxO PhotoLab 9 simplify this, turning raw scans into editable positives without third-party plugins. In the video, I use scans from an Epson Perfection V850 flatbed scanner on Ektar 100 (from a Pentax 645NII) and Portra 400 to demonstrate real-world results. The goal? Efficient workflows that preserve film's unique look while allowing creative tweaks.
Whether you're digitizing old family rolls or archiving pro shoots, mastering this saves time—especially with presets tailored to specific film stocks.
Step-by-Step: Inverting and Optimizing in DxO PhotoLab 9
The video focuses on practical steps; here's a detailed breakdown to follow along.
Prepare Your Scans: Scan negatives as positives (no auto-inversion) for maximum control. I recommend flatbeds like the V850 or DSLR/mirrorless setups for high-res results. Load your RAW scans into PhotoLab.
Invert the Image: Navigate to the "Color" tab. Under HSL, find "Scanned Film Optimization" (it may be grayed out—click to activate). Hit "Invert the Negative Image." This flips the image linearly (light to dark, dark to light), but colors will look off initially.
Choose a Starting Preset: DxO offers presets (e.g., Linear, #1-13). Ignore colors at first—focus on contrast. For punchy films like Ektar 100, try #13 for an S-curve boost. For low-contrast stocks like Portra 400, start with #1. Preview the curve graph to see the impact.
Adjust RGB Curves for Color Correction:
Red Channel: Often the culprit for casts. Pull highlights/shadows toward green to neutralize reds (e.g., in skin tones or bricks).
Green Channel: Add a control point on neutral areas; shift toward magenta for balance.
Blue Channel: Move toward yellow to fix cool tones. Make small adjustments—big moves can overcorrect. Zoom into skin, sand, or neutrals for accuracy.
Fine-Tune and Save Presets: Once satisfied, save via the preset dropdown (e.g., "Ektar 100 Normal," "Ektar 100 Vibrant," "Ektar 100 Skin Tones"). This creates reusable profiles for batch edits. For Portra, aim for subtler contrasts to match its natural look.
Apply to Batches: On new images, invert, then select your preset. Tweak as needed for scene variations (e.g., more saturation for vibrant shots).
In my tests, Ektar scans turned punchy and contrasty, while Portra stayed soft and true-to-life—proving the tool's versatility.
Tips for Better Results
Film-Specific Presets: Create variations (normal, vibrant, skin-focused) for each stock. Ektar loves high contrast; Portra needs subtlety.
Common Pitfalls: Avoid over-editing curves—small shifts suffice. If scans look "off," check scanner settings (e.g., disable auto-corrections).
Hardware Pairings: Use with scanners, DSLRs, or even smartphones for digitizing.
Post-Inversion Edits: After conversion, use PhotoLab's full suite (HSL, noise reduction) for final touches.
