If you're an Iridient Developer user and a Fuji X-Trans shooter (X-Pro 1, X-E1, X-E2, X100s, X100t etc) the developer of the software has posted film simulation presets to match the ones that are available in camera. They've actually been available for a little while, but they've just posted some updated versions. According to the website:
These film emulation style presets are intended to produce a similar look to the X-Trans in-camera conversion styles for Classic Chrome, Standard/Provia, Soft/Astia, Vivid/Velvia, ProNegStd, ProNegHi, Monochrome, Monochrome+Ye, Monochrome+R, Monochrome+G and Sepia.
The presets require Iridient Developer 3 and they're available now from the Iridient Developer website.
