|Profiles are built on a 900+ colour calibration chart and compared against the in-camera JPG profile simulations.|
This is a little update to my last post of my Velvia 100 RVP Film Simulation with a link to the preset for your own use. It has been really well received and I thank all those who have sent me feedback and also donated to the cause. Every little bit is appreciated.
Above you can see a little sample of my work flow in matching profiles to the colours it presents. This specific example is matching the in camera simulations made by my X-Pro1 and adjusting the RAF file to match each of the different simulations.
I started this project back in November but wasn't completely happy with the results. Matching across 900 different colours was the easy part (as in the example above), but there were other factors that were alluding me at how at least in this case, how FujiFilm was creating their profiles. When I applied the adjusted profiles from the colour calibration chart onto a live image, it didn't work.
I made some recent discoveries from my own generic Velvia 100 RVP film simulation development that helped bring me back to working on this profile. Below is a sample of my results which is very close. Bear in mind that JPG images are only 8 bit, and the RAF files are 12bit>16bit images which of course makes some of the matching a little challenging.
For X-Trans users who have been looking for presets that match the in-camera JPG simulations, I'm hoping to have those simulations out very soon.
The bonus of these presets is that although I'm working on making a specific preset for the X-Trans sensors, these presets can be used for other cameras as well. But my primary objective is first to match the camera output as much as possible then to make it available to the public.
Thanks to all my supporters as I continue to develop this.
You are always welcome to download my presets for free, but I also welcome donations to my efforts:
|Once a profile has been built, it is compared against live samples. Some adjustments made, and thrown back at the calibration chart. It's a painstaking process of doing this manually back and forth.|
