It is currently available in one speed, 100/21°, marketed as Fujichrome Provia 100F Professional [RDP III],.[2][3] An additional speed of 400/27°, marketed as Fujichrome Provia 400X Professional [RXP],[2][4] was previously available. DetailsProvia 100F [RDP III] was developed to replace Provia 100 [RDP II] and Provia 400X [RXP] was developed to replace Provia 400F [RHP III],[5] improving on colour image storage permanence and colour fading resistance.[4] Provia has less saturated colors and contrast compared to Velvia. Provia 100F [RDP III] is available in 135 and 120 formats, as well as {{convert|100|ft|m}} rolls and various sheet sizes. Provia 400X was only available in 135 and 120 formats prior to discontinuation.[3][4] Both films have the ability to be pushed/pulled from −1/2 stop to +2 stops.[3][4] Provia is also a favored film for cross processing. Neither film requires reciprocity compensation between 1/4000 sec and one minute, with Provia 100F [RDP III] able to last up to two minutes.[3] These longer times make the films particularly suitable for multiple exposures. Provia 400X [RXP] used what Fujifilm described as Epitaxial Sigma Crystal (ESC) technology to achieve a granularity of RMS11.[4] See also
