A lot of ARRI Alexa users have been utilising X-H2S as B or C cams due to their great image and incredible features and need a LUT to colour match the 2 camera systems. As well as this, a lot of X-H2S users have emailed me describing their dissatisfaction with the native colours coming out of their camera. To address these issues, I decided to develop a LUT to emulate my Alexa Mini using the tried and true process I developed with Sony, Canon, DJI, Blackmagic and Panasonic cameras. While no camera is perfect, personally I find the Alexa’s colour science to be the gold standard in terms natural, accurate and beautiful colours right out of the box as a starting point to grade from.

Over the course of a few days, I shot exposure matched test footage with my Alexa mini and X-H2S side by side. I shot in sunlight, shadow, overcast, indoor daylight, indoor mixed lighting, controlled studio lighting and all with my trusty Xrite Colour Checker Classic Card and my Xrite Digital Color Checker SG Card.

In total I shot approximately 80 scenes this way. With each set up I recorded 3 exposures - under 2 stops over 2 stops and correct exposure. With the extensive data gathered, I was able to build an emulation that is extremely accurate; factoring in not just the overall colour response but also the more subtle aspects of the Alexa colour science that it borrowed from photochemical film such as it’s non linear hue responses for rich, complex colours, subtractive colour modeling in relation to luminance vs saturation dynamics and the Alexa’s overall saturation profile for beautiful highlight rolloff and shadow falloff to name a few.

Phantom Fuji X-H2S LUTs

For FUJIFILM X-H2S users who need to colour match with an ARRI Alexa, want more creative choices for their post workflow or who are unsatisfied with the standard F-Log2 to Rec709 technical LUTs on offer, I have developed a LUT that accurately emulates the ARRI Alexa 709 colour science for F-Log2 for the X-H2S camera.
