Hi,
Start RawWork. Start from the menu RawUtil.
Try different settings. I don't know the parameters of your camera. My camera is with 2048/1536 JPG but the settings in RawUtil are 2064/1542.
Very important (if using Adobe Photoshop) - thick Compatibility mode. Other RAW converters don't need it.
Good luck :bye:

I tried with 2272x1704 (native size according to http://www.dpreview.com review) and with 2288x1712 (as announced in the manufacturer's site).

BPP was always left at 12.

I tried with RGGB and GRGB patterns.

The file size was 5935104 according to windows explorer.

Finally i turned on and off all additional options (not knowing what most of them mean doesn´t help).

The left image is the best i got and the right is the jpg version (both scaled, naturally).
You can barely make out the horizon.

Probably it just won't work, unless you have any suggestions...

NOTE: I'm using dcraw.exe with the -a option to convert the NEF file.

Hi,

A simple calc shows that the real resolution is different (bigger) from the one you used:
2288*1712*12/8-5935104 = -59520

Try increasing the resolution. In my case (C740) the above calc is 2064*1542*12/8-4775936 = -1904
Those 1904 bytes (in my case) are for internal file format use. Note that the JPG resolution is 2048/1536.

Try to convert the RAW file directly with the DCRAW program. Put it in separate folder (without the JPG) and run in command line "DCRAW.exe your.jpg".

If you do not succeed you can upload the RAW file somewhere and send the link (PM) to me. I could give a try.

Good luck!

I would try the resolution of C770UZ (2304/1718 with RGBG) and play with the other settings.

That didn't work, in fact Raw Work didn't produce any output, and if ypu replace that resolution in the formula you gave me it returns a positive value. Also, Raw Work's 770UZ and 765UZ default modes don't produce output.

I solved that formula to give me the resolution that returned -1904 while maintaing the aspect ratio:

(1.334*x)*x*12/8-5935104 = -1904

It gives x=1721.95

and y=1.334*1721.95=2297.08

So i ran Raw Work with 2297x1722, but it still didn't work.

Luck with me!

I succeeded @ 2304/1716 with only "Interlaced CCD" thicked.

Have tried with different paterns RGGB, RGBG & GRBG. Can not see any difference.

Tried with "Shift Right" and "Shift Down" but the colours look strange.

You can un-thick Compatibility mode and then you receive clean picture (without the black frames). As I know the new Photoshop (CS2) can import those pictures. The old (CS) can not and then you need "Compatibility mode" thicked.

Enjoy your RAW format. You need to process the file to make it more sharp and to adjust the white balance.
