Sharpening is one of the most taxing aspects of the digital process and consequently many photographers prefer to stick to safe and secure ways, either using presets, plug-ins, exporting to Photoshop or ultimately using JPEGs straight from camera. The X-Trans sensor produces wonderful JPEGs, and all the usual advice about always shooting in Raw doesn’t necessarily hold true anymore. There are now many professional photographers who happily shoot JPEG using X-Series cameras all the time and have no complaints.
JPEGs are very convenient, but for a landscape photographer like me, interested in the creative process and using post-processing as part of the digital alchemy, Raw files are so much more versatile. Sharpening Raw files from the X-Trans processor can be challenging for those of us who have grown familiar with more traditional Bayer array sensors; they demand a different approach and even experienced photographers will find there is a learning curve.
