Kodak Portra 400

Overview

Kodak Portra 400 is the middle member of Kodak's professional color negative line (Portra 160 / 400 / 800) and the most-used professional color negative film in wedding, portrait, and editorial photography today. Current formulation reformulated in 2010 as part of the Portra-family refresh that also produced the Portra 800 covered on photographyFYI. Portra 400 shares the family hallmarks — natural warm skin tones, muted saturation, exceptional overexposure latitude — while occupying the practical sweet spot of ISO 400 (fast enough for most available-light work, slow enough to retain the finest Portra grain).^[1]

Positioning within the Portra family

The Portra line covers three ISO ratings with consistent color palette and tonal character:

• Portra 160 — 1-stop slower; finest Portra grain; daylight-only practical
• Portra 400 (this film) — the middle; the workhorse; 35mm / 120 / 4×5 availability
• Portra 800 — 1-stop faster; low-light/indoor; 35mm / 120 only

Portra 400 is the default choice for most professional color negative workflows. Wedding photographers typically carry Portra 400 primary with Portra 800 backup for reception work; editorial photographers use Portra 400 for mixed daylight/indoor scenes.

The "rate at EI 200" overexposure workflow

Portra 400, like its siblings, has unusually wide highlight latitude (~5 stops over) and moderate shadow latitude (~2 stops under). This asymmetric latitude makes overexposure a common Portra-family workflow:

• EI 200 (1 stop over box) — most common pictorial rating; smoother grain, richer midtones
• EI 100 (2 stops over) — for portrait work prioritizing skin texture; accept tighter exposure tolerance
• EI 400 (box) — honest delivery; use when speed matters
• EI 800+ (push) — see Push Processing below

Rating at EI 200 is so common that many labs' default scanning profiles assume a 1-stop-over exposure. For photographers new to Portra, start at EI 200 for richer output; move to EI 400 if speed is a constraint.

See the Portra 800 page for a fuller treatment of the overexposure ritual (same rationale applies to both films).

Grain and resolution

Portra 400's grain is meaningfully finer than Portra 800 and at 120 format becomes effectively invisible in normal prints. Per-format behavior:

• 35mm — Visible at 4000 DPI scans; structured and pleasant; enlarges cleanly to 11×14
• 120 — Grain essentially invisible at normal print sizes; 6×6 crops scan at 400+ megapixel equivalent
• 4×5 sheet — Portra 400's sheet-film grain is absolutely invisible; suitable for mural-scale enlargement

Color palette and skin tones

Identical family signature to Portra 800:

• Skin tones — natural warmth; flatters most complexions; the Portra-family defining feature
• Warmth — subtle global warmth; less than Gold 200, more than Ektar 100
• Saturation — deliberately muted; Portra is not a "pop" film
• Shadows — retain color detail; don't crush to black
• Highlights — roll off gracefully; no paper-white burn under overexposure

The palette is optimized for skin rendering and editorial use — not for saturated landscape (Ektar 100) or neon street (Cinestill 800T).

Push processing

Portra 400 pushes cleanly to EI 800 (+1) with minimal color shift; EI 1600 (+2) with moderate warming. Push times: approximately +30% in C-41 at the lab. Beyond +2 push, color casts become aggressive.

For low-light work requiring >EI 800, switch to Portra 800 (box speed EI 800 with Portra's native characteristics) rather than extreme-pushing Portra 400.

Reciprocity failure

Standard color negative reciprocity:

• 1 second metered — no correction
• 10 seconds metered — ~½ stop additional
• 60 seconds metered — ~1 stop additional + slight magenta cast
• 5+ minutes metered — bracketed testing recommended; color casts variable

See [[reciprocity-failure]] and Reciprocity Failure Compensation for complete workflow with ND filters.^[1]

C-41 processing

Standard C-41 chemistry; no special considerations. Standard time-temperature (3:15 at 37.8°C / 100°F), standard agitation, standard bleach/fix/stabilizer. Any commercial C-41 lab processes Portra 400 routinely; home developers (Cinestill Cs41, Tetenal Colortec) handle it alongside other C-41 stocks.

Format availability

Portra 400 is currently available in:

• 35mm — 36-exposure cassettes, pro packs of 5
• 120 — 5-roll pro packs
• 4×5 — 10-sheet boxes (limited; the only current Portra in sheet format)

No 8×10 offering. Pricing at Kodak's professional tier — roughly 50–80% more per roll than Gold 200 at mainstream retail.

Manufactured at Eastman Kodak's Rochester, NY plant; distributed worldwide by Kodak Alaris, the British spinoff that retained distribution rights to the Portra and T-Max trademark families after Eastman Kodak's 2012 bankruptcy reorganization. (Eastman Kodak resumed direct distribution of several other films — Tri-X, Gold, UltraMax, Ektar, Ektachrome — in 2024–2026, but the Alaris-trademarked Portra family remains under Alaris distribution as of 2026.)

Shelf life: refrigerate for 2+ years; freeze for 5+ years; room-temperature acceptable for 6 months.

Comparison with alternatives

Film	ISO	Grain	Palette	Positioning
Portra 400 (this film)	400	Fine	Natural warm, muted	Professional portrait / wedding / editorial
Portra 160	160	Very fine	Same family signature	Daylight-only pictorial
Portra 800	800	Medium	Same family signature	Available-light reception/concert
Fuji Pro 400H (discontinued 2021)	400	Fine	Cooler, greener	Historical competitor
Ektar 100	100	Very fine	Saturated, punchy	Landscape / product
Kodak Gold 200	200	Medium	Warmer, more saturated	Consumer/casual

Portra 400's distinctive position: the middle speed with the Portra family's professional palette, availability in 35mm/120/4×5, and the widest exposure latitude in its ISO class.

Workflow recommendations

• Wedding ceremony (daylight) — EI 200 in 35mm or 120; scan flat, adjust minimally
• Wedding reception — EI 400 as light drops; 1-stop push if necessary (or switch to Portra 800)
• Editorial portrait — EI 200 for smoother skin rendering; EI 400 if handheld at dim interior
• Travel documentary — EI 400 box speed in 35mm; Portra 400 is the classic travel color negative
• Large-format landscape — EI 400 in 4×5; the only current professional color-negative sheet film

Famous users and cultural context

Portra 400 and its predecessor formulations have been the dominant wedding-photography film since the 1990s. Fine-art photographers using Portra 400 include Stephen Shore (later color work), Alec Soth (various series), Joel Sternfeld (American Prospects). Editorial portrait photographers universally relied on Portra for the two-decade era between 1998 (original Portra introduction) and present.
