I have tried to process X-Pro1 RAW files with Lightroom and have not been very happy with the results. This is especially true with high ISO shots. ISO 1600 is totally okay but I will need ISO 3200 and even 6400 often. With that high values I am getting quite mediocre results.
When shooting JPEGs even ISO 6400 is quite clean of noise. Below is a shot taken with ISO 6400 and I even added some grain by using a VSCO Film preset. And I feel very comfortable with that shot and result. You can see evolution in that shot. I really hope Lightroom’s RAW converter will have same kind of a evolution – from dinosaurs to elephants.
