I am an avid DSLR photographer and a couple of years I have switched to shooting all my images in RAW and I have never looked back. Using a RAW format retains much more of the information captured by the sensor during the exposure and places the power to develop these 'negatives' yourself. Usually the camera does this process automatically and spits out a JPEG image. Shooting in RAW gives you much more control over the look and feel of your final image and I think it's an invaluable tool to photographers.
The XF1 offers shooting in FujiFilm's proprietary .RAF format. You can also shoot in RAW + JPEG so you get the best of both worlds. Here are a few examples of the JPEGs created directly by the camera as well as the RAW images after I processed them in Adobe Lightroom.
Before I could work with the RAW images from the FujiFilm XF1 in Adobe Lightroom, I had to upgrade to version 4.2 since it was the earliest version to support the FujiFilm .RAF format. But once I was set up, I ended up shooting almost all images with the XF1 in RAW.
Photography is all about light. Therefore cameras struggle big time when it comes to shooting in situations where there is very little of it. This applies especially to night time photography. To compensate for the lack of light hitting the image sensor, the camera will open up the aperture as wide as it can and increase the ISO to amp up the sensitivity of the sensor.
While the aperture of the FujiFilm XF1 can open up to F1.8 it's usually not enough during night and so the ISO rises to quite extreme levels depending on the shot you are taking. This causes a lot of noise in your image as can be seen in the picture below.
To deal with exactly this situation, the FujiFilm XF1 provides an EXR High ISO Low Noise mode. With this mode, the camera takes a a quick sequence of images and combines them to reduce the noise in the final photo. I was actually impressed with how well that worked. Below is the same scene, shot with the EXR High ISO Low Noise mode of the XF1.
Let's look at the video capabilities of the FujiFilm XF1.
Just wanted to say a great review from somebody that can take a good photo, I'm just waiting delivery of my XF1 and this review has helped outline some very good pointers.
