Irfan shows that picture has 24 bit (hm my Nikon's nef has 12.. ;( )
There is lot of noise in dng. But Photoshop+Imegenomic Noiseware is much better than antinoise algorithm in ixus100

Are you able to open DNG from ixus 100 in photoshop? Does it 'just' work, or do you use some plugin for this?

No, unfortunatly i can't do it.
First i open dng in irfanview --> Save as tiff --> Open in PS (or open as camera raw in ps)

@Jestik: Thank you for your comparison.

You could test whether DNG has really more information (more bits) when you shoot in a bright spot with a dark area. When you lighten up that area (adjust contrast or something) there should be a slight difference.

The raw is only 12bit so I imagine the DNG has to be similar.  :)

hm.. i always thought that RAW can be 12 or 14 bit. But, ok, it doesn't matter :)
i think in cameras with such small sensor RAW can't be panacea, but it something really helps when i need to correct shadows and highlight.
Anyway many thanks to HapoMa.

It can be all sorts but alas the sensor only gives 12 bit (vs 10 bit for earlier SDs)

I have just noticed that all of my DNG photos have a black stripe, few-pixels wide on one side. Is it just my camera, or do you guys also get it? On jpg there is no stripe.
