Mark,

with JPEG’s etc the camera’s image processor increases saturation and contrast before writing the JPEG file. With raw (in Canon’s case *.crw) this is not done (look at it as if the image processor in the camera is replaced by your computers and its software, RawStudio in this case).

It is very likely that yuo will want to add saturation and contrast to almost every image (which is why a settings copy feature is essential…).

Rawstudio is the most intuitive of the photo apps I have tried. I love it’s workflow but ALL of my images need to have contrast and saturation bumped up else the image is flat looking. this forces me to duplicate these changes on EVERY image.
Is there a setting that I am missing? My current settings are RawStudio 1.0 in Ubuntu 8.04. I have tried Preferneces…Colour…Experimental on and off. On gives slightly better results.
The resulting images all appear flatter than the original NEF or associated JPGs when viewed and output through RawStudio.
‘Tis a pity because I love the way it is designed.

check out enabling RAW in home grade cameras
(i used it for my Canon 640A)
http://chdk.wikia.com/wiki/CHDK

updating the firmware with those addons upgrades the
camera’s features and abilities to handle RAW picture capturing

Thanks Joel.

I have been looking for good raw processors for Ubuntu. Here is another article experimenting with raw processors on Linux that I found quite helpful. I think between your article and his I have found what I need.

By the way, I just installed Raw Studio on Ubuntu 8.04 and it appears that Raw Studio 1.0 is in the default repositories. I found it via the simple Applications -> Add/Remove tool.

Thanks again!

FYI, if the saved PNG is 16 bit (which the format supports) then you are losing no quality whatsoever compared to TIFF, and gain better compression, support for metadata and better overall compatibility (TIFF isn’t a fully specified standard).

Given the choice you should use 16bit PNG over TIFF.

Xavier,

Send me the details of your problem by private email. I tried the getdeb.net version without problem the other day.

Take care,

Joel

Hi Joel,

Indeed, I’ll wait until a fixed package is released.

Thanks

Xavier,

Remember that version 0.6 doesn’t has the full size demosaicing algorithm – your TIFF / JPEG images are only half size, which is not very useful. I’ll have a look into the getdeb.net package to see if I can reproduce the Pango issue…

Take care,

Joel

Hi Joel,

So far, I’ve installed a version 0.6, but I got an error with libpango when I tried to install the version 0.7 from getdeb.net . I’ll retry later. Hopefully a fixed package will be available soon.
Anyway, I’m gonna try the version 0.6

Thanks for your help

Salut Xavier!

Congrats – once wifi is working on Linux, all the rest is a piece of cake (almost). RawStudio is available in Universe, the standard *buntu repositories. However, this will be version 0.6.1.

My take is:
1) install version 0.6 so you have the dependencies satisfied
2) grab a version 0.7 from http://www.getdeb.net/search.php?keywords=rawstudio
3) just double clicking on the deb file should fire gdebi which will allow you to install after asking you if you really want to overcome the standard version.

Let me know if you have any trouble.

Take care,

Joel
