Decoding X100 RAW files

I've email David Coffin of DCRaw [1] with a query about X100 support id DCRaw.

He was kind enough to provide me with a preliminary patch, which I'm assuming falls under the same license as DCRaw itself.

I've posted the patched source code as well a windows binary (and instructions as to how it was compiled) to my Dropbox account, where it will be available for a limited time.

You can download all of this, including 3 RAW conversions from QueSabesDe's "preview" [2] from here: http://db.tt/jSGfK7R

I want to stress that these are preproduction samples from a camera with firmware 0.69. Also, the camera has obviously not yet been color calibrated for DCRaw. Take these samples with a grain of salt.

With that said, if you have any other RAW files you can link too, please share them in this thread.

Thanks!

Thank You very much!
And of course thanks for Dave Coffin for his excellent raw decoder.

I love dropbox! The files will be waiting for me to look at when I get home. Thanks for posting this.

Re: Decoding X100 RAW files

Looking at the files. It seems like there is just a bit of CA correction, and no distortion correction in the raw conversion.
The guys at Fujinon have done their job well.

Exif? Banding.

I downloaded your png, but see no exif. The shot with the colorful plastic cups on ice has banding.

Could you tell us which shots were taken at which setting? I'm particularly interested in what ISO the plastic cups were taken at.

About picture data

As I've said in the OP, the image samples were taken from [1]. You can download the original RAW files there. Initially, there were also links to in camera JPEG conversions there too, but since they seem to me missing, I'll reference them here.

Re: Nice :]

I decoded the X100 RAW files in the day 20 of February at 2:00am GMT (judging by the last compilation time), I used my old RAW decoder for HS10 ;]

I used an hex editor to check for file structure and manually extracted the offset from TIFF tags and manual analysis, after that I empirically test the pixel data (with HS10 I extracted bit statistics and decoded it in a more scientific way), until I got an valid image, then applied tried out a few color array filters and basic demosaicing to be amazed of how good it looked with the cups, since the shot was taken at ISO 3200 ....

In the end I got this image by pixel binning demosaicing, gamma correction to screen (but not color calibrated), resized - because my internet it's just to slow - and with AWB from GIMP (because you wouldn't like a green image):

Obviously, and in contrast with HS10, offset is not the same for all pictures, this is what happened when I applied the same code (with hard-coded offsets) to other RAW:

Well, I was bored when I started messing with RAW files, so after that and being 2am I forgot about it and went to bed...

Nice work, and thanks to Dave Coffin for doing such a great (and fast) job with it...

How about this version

zebarnabe Regular Member • Posts: 102
Much better indeed...

For anyone wondering that one - the original from quesabesde - was taken at ISO 200, f/5.6, +0.7EV, 1/150s

X100 it's quite something, but that 1000€ tag scares lots of people :/
