Provia is a brand name for a pair of daylight-balanced color reversal films (slide film) produced by the Japanese film company Fuji film. It is currently available in one speed, 100/21°, marketed as Fujichrome Provia 100F Professional [RDP III],.[3][4] An additional speed of 400/27°, marketed as Fujichrome Provia 400X Professional [RXP],[3][5] was previously available.
Details
Provia 100F [RDP III] was developed to replace Provia 100 [RDP II] and Provia 400X [RXP] was developed to replace Provia 400F [RHP III],[6] improving on color image storage permanence and color fading resistance.[5] Provia has less saturated colors and contrast compared to Velvia.
Provia 100F [RDP III] is available in 135 and 120 formats, as well as 100-foot (30 m) rolls and various sheet sizes. Provia 400X was only available in 135 and 120 formats prior to discontinuation.[4][5]
Neither film requires reciprocity compensation between 1/4000 sec and one minute, with Provia 100F [RDP III] able to last up to two minutes.[4] These longer times make the films particularly suitable for multiple exposures.
Provia 400X [RXP] used what Fuji film described as Epitaxial Sigma Crystal (ESC) technology to achieve a granularity of RMS11.[5]
