Fujifilm HS30 EXR JPEG vs RAW

To compare real-life performance between RAW and JPEG files on the Fujifilm FinePix HS30 EXR, I shot this scene in the camera's RAW plus Large Fine JPEG mode enabling me to compare images created from exactly the same data. The sensitivity was set to 100 ISO and the aperture to f5.6.

The JPEG was processed using the in-camera defaults, while the RAW file was processed using the supplied Raw File Converter EX 3.2 software which is based on SilkyPix. The conversion was done first using the software's default settings, I then tried to improve on the default result by tweaking the parameters.

The image above was taken with the Fujifilm FinePix HS30 EXR.The camera was set to Aperture priority mode with the aperture set to f5.6 and the sensitivity was set to 100 ISO. The HS30 EXR metered an exposure of 1/850 at f5.6

It's immediately appearent from the crops that the RAW file conversion using the software's default settings produces quite a disappointing result that doesn't come close to the in-camera JPEG in terms of overall quality. Looking at the first crop, there's a lot less detail in the RAW file conversion and what there is looks blurry and smeared. The lighthouse in the second crop is a lot less distinct and, more worryingly, the windows in the middle distance of this crop appear to be sufferring from the same jagged edge 'aliasing' effect that was evident in the central crop from the outdoor test results. That's the same crop as the fourth crop on this page where you can see that the effect is much more pronounced in the RAW conversion.

I tried for quite some time to eliminate, or at least minimise this artifact without success. It begins to appear when you apply output sharpening (as opposed to demosaic sharpening) in Raw File Converter EX. Applying the No Sharpeness preset gets rid of it, but results in a very soft image. And if you apply unsharp Mask, either in the output settings when you save the file from Raw File Converter EX, or later in Photoshop, the jagged edges make an unwelcome return.

In the end it comes down to striking a balance between image sharpness and reducing the effect. The best I could manage was by reducing the Outline emphasis and detail emphasis from their defaults of 60 and 75 to 50 and 40 respectively, then increasing the False outline control setting from 0 to 20. The result is an improvement on the default, but overall, though the jagged edges aren't as much of a problem as in the in-camera JPEG, I don't think the result is as good.

Now check out how the camera performs in my Fujifilm HS30 EXR noise results.
