Colours of the image posted by Simone appear very natural and life-like (this landscape and its appearance is very familiar). Details look good too. A lot of the output otherwise have smeared rendition of fine branches against the sky etc.
Thanks for the comment Bjørn.
A note to all Iridient users regarding Fuji files: the presets that can be freely downloaded are highly recommended.
The default rendition has excessively saturated colours and somewhat altered tonalities; this applies especially to reds.
I tend to use the "negative" presets for more natural-looking colours, especially when people are involved or when there are lots of reds. The image then benefits from some added saturation and vibrance (the saturation tool is "smart" in that it has some inbuilt protection against blowing channels).
For images with lots of contrast the ProNegStd preset allows much better highlight and shadow recovery; the default result usually has shadows that somewhat lack punch but one can add back contrast to taste during development.
For more punchy images out of the box ProNegHi works well.
I fairly often use Natural for landscape images, this gives fairly punchy and saturated images without going overboard. I always try Natural or ProNegHi + saturation/vibrance before deciding.
