When to Choose Portra 400

Portra 400 is the film stock that makes everything look like a memory you want to keep. Its color rendering is unmatched for human subjects and natural environments.

When color tells the story -- A field of wildflowers, the blush on someone's cheeks, the warm glow of late afternoon light through curtains. Portra preserves and enhances the colors that give a scene its emotional context.
Professional portrait sessions -- Portra's skin tone rendering is the industry benchmark. It flatters every complexion and handles mixed lighting with grace. Clients expect to look beautiful, and Portra delivers.
Soft, emotional narratives -- If your work leans toward intimacy, tenderness, and quiet beauty, Portra's gentle contrast and warm palette support that mood naturally.
When you need forgiving exposure latitude -- Portra handles overexposure beautifully, with highlights that roll off into creamy, luminous tones rather than harsh clipping.

When to Choose Tri-X 400

Tri-X 400 has been the backbone of photojournalism and street photography since the 1950s. Stripping away color forces the viewer to see in terms of light, shadow, form, and gesture.

Street photography and urban scenes -- Tri-X turns city streets into graphic compositions. Hard shadows, geometric forms, and human figures become the subjects. Color distractions disappear, and the photograph becomes pure observation.
Documentary and photojournalism -- There is a reason every major photojournalist from the 20th century shot Tri-X. Its high contrast and forgiving latitude let you focus on the moment, not the exposure meter.
Dramatic, editorial portraits -- When you want a portrait that feels like a character study rather than a beauty shot. Tri-X renders skin with sculptural dimension, emphasizing bone structure and expression over smoothness.
High-contrast architectural and abstract work -- Buildings, staircases, shadows on walls. Tri-X's punchy tonal response makes geometric subjects feel monumental.
