2012

RAF — Raw Fujifilm — shipped in 2003 as the raw format for Fujifilm’s Super CCD sensors. Unlike most competitors, Fuji’s sensors use an unusual pixel arrangement (the X-Trans pattern since 2012, replacing Bayer’s traditional RGGB grid), which makes RAF files harder to demosaic than a typical raw. Adobe Camera Raw spent years improving their X-Trans algorithm; Capture One and Iridient Developer emerged as favored alternatives.

Fujifilm built a cult following among photographers who love the company’s film simulations — digital renderings of classic Fujichrome and Velvia stocks. RAF files carry the recipe of which simulation was applied at capture, but the actual film-curve magic happens inside Fuji’s X Raw Studio software. Getting non-Fuji tools to match the look has been a decade-long cat-and-mouse game.

MERAK EDİLENLER VE
İLGİNÇ BİLGİLER.

Fuji's X-Trans sensor uses a 6×6 pixel pattern (vs Bayer's 2×2) — harder to demosaic but reduces moiré without a low-pass filter.

Film simulations (Velvia, Astia, Classic Chrome, Acros) are baked as recipes in RAF files — applying them in third-party tools never perfectly matches Fuji's X Raw Studio.

The GFX medium-format bodies also write RAF — same extension, much larger sensor data (102 MP on the GFX 100 II).

RAF files contain an embedded JPEG preview at full resolution, which is what EVF and camera playback actually display.

Fuji photographers famously argue about whether Capture One or Iridient's X-Trans processing looks more natural.
