===Velvia 100===
Velvia 100 was introduced in 2005, to replace the discontinued original Velvia.<ref name="BJP"/> It is about as saturated as the original version but was designed to be more accurate in color reproduction.<ref name="Velvia100"/> It used the new "Super-fine Sigma-crystal" technology which ended the need for larger grain size to achieve greater film speed. The newer speed also has finer grain (an [[RMS granularity]] value of 8), and uses the color correction layers found in [[Provia]] 100F. The Advanced DIR Technology releases developer inhibitors release compounds that regulate interlayer and edge effects yielding dramatic improvements in color reproduction. The color rendition of Velvia 100 was designed to record all colors even more accurately. Reciprocity failure was reduced for long exposures and dye stability extended. Fujichrome F transparency films held color accuracy for years of archival color stability, while Kodachrome films faded in less than 20 minutes of accrued projection.{{Citation needed|date=June 2023}}

On July 6, 2021, Fujifilm announced the discontinuation of Velvia 100 within the United States, effective immediately. The chemical phenol, isopropylated phosphate (3:1) (PIP (3:1)) (CASRN 68937-41-7), the use of which is banned under the EPA's Toxic Substances Control Act (TSCA), is present in minuscule quantities within the layers of the film. While Fujifilm believes the trace amount is not harmful to the environment, they opted to discontinue the film within the United States in compliance with the regulation. Their statement does not make it clear if the film will continue to be sold in other markets.<ref name="FUJICHROME_Velvia100"/>
