DCRAW でDP-1 の現像を試みる(失敗)

RAW X3F sigma linux camera koedolug

桔梗さん(@akiha_tohno)に小江戸のオフで教えていただいたDCRAW

- Decoding raw digital photos in Linux
http://www.cybercom.net/~dcoffin/dcraw/

SIGMA の一眼レフSD14 も行けるようなので同じイメージセンサ(Fx17-78-F13D)のDP-1 でもいけるのではというとこで試してみました．

$ apt-cache search ^dcraw$
dcraw - decode raw digital camera images

ということでパッケージがあるのでこれを導入．
早速tiff への変換を試してみます．

matrix が見つからなくてAuto で変換したようです．
開いてみると，noiz だけの謎画像になりました．
SDIM0431

パッケージのバージョンを確認するとv8.86 で，最新は9.04 の様なのでVersionUp で対応されてないかなと試してみましたが，結果は同じでした．

$ wget http://www.cybercom.net/~dcoffin/dcraw/dcraw.c
$ gcc -o dcraw -O4 dcraw.c -lm -ljpeg -llcms
$ ./dcraw -T ../SDIM0431.X3F

残念…．
