more pixel from your DSLR :)

nightpiper · 14th January 2005

hi all Oly users, just pop into dpreview & saw this very interesting thread about getting more resolution by using some Linux imaging software plugins. i dun know anything about Linux, if any of u r using Linux, pls tell us how u find the overall quality besides the increase in resolution.

http://forums.dpreview.com/forums/re...ssage=11815026

just for convenience sake, i put a quote here for all to see:

When I run dcraw under The Gimp image editor (both are free), I get a 3337 x 2502 instead of the normal 3264 x 2448. This is a gain of a rather significant .36 megapixels, which bumps the pixel count up to 8.35 MP. It will probably do something similar with the E-1.

I thought the OTF forum would want to know this, as there is real information to be found in the added pixels (it doesn't just make the image larger). I would like others to confirm this for me. I've combined two of my posts below on installation of dcraw and the Gimp as well as the advantages of the Gimp and dcraw.

dcraw does not work under Windows as is. Follow these 5 simple steps to install:

1) Install the Gimp 2.2 using the link below (install GTK first and then the Gimp).

2) Download UfRaw if you have the E-1 or RawPhoto (http://www.princeton.edu/~mplough/rawphoto.html) AND dcraw.exe (http://home.arcor.de/benjamin_lebsanft/) if you use the E-300.

3) Place the UfRaw.exe (for E-1) or rawphoto.exe (E-300) in Gimp 2.2\lib\gimp\2.0\plug-ins
4) (Only for E-300) Place dcraw.exe in GIMP 2.2\bin

5) Open a Raw file in the Gimp (or use Open with... by right clicking on the .orf file).

Gimp uses UfRaw for RAW conversion: see http://www.aei.mpg.de/~udif/UFRaw/. Converts in 16-bit and allows for custom tone curve profiles. Real-time histogram in RGB. UfRaw uses dcraw as the conversion utility, which is an excellent conversion utility according to http://www-ise.stanford.edu/%7Etingchen/main.htm as it uses VNG interpolation. UfRaw has dcraw already built in.

Well Nightpiper,

You have raised the ante for technical reporting on this forum :-)

My mouse will be clocking marathon-like mileages to come up with any useful response :-)

Interesting subject though.

Thanks !

hi chancy, how about u supply us with info on how to shoot infra-red pics with our E1/E300. u know, those DIY dismantling cameras & taking out filters on the CCD? u can be 'the chosen one'.

i can sense the force is strong with u.

looking forward to hear from ya.

Hi Nightpiper,

Sorry to let you down, but I believe Tomcat is the authority on this has written an article and posted pict(s) on IR here, abeit on his EOS and techniques appear specific to EOS sensors.

Correct me if my memory is wrong.

Cheers,
