I’m discovered a few days ago that eye of gnome (eog) in the ubuntu 7.10 release picks up the color profile if it’s set with the xicc tool. Eog also read embedded color profiles from jpg images.
I tested this on a laptop. The xicc are place in the universe repository, and can be installed with sudo apt-get install xicc. Other tools that support this feature are listed here. Read the rest of this entry »
I tested canon’s Digital Photo Professional (DPP) software a few days ago on one of my linux box. I like to take some notes for myself for later use. I have installed DPP a few times today just too fine tune the documentation. I even tested it on an ubuntu live cd, just to be shore it will work for most people.
The picture at right is straight from dcraw in 8 bit mode. In this post I try to find out what dcraw does in 8bit mode versus 16 bit mode. The point for me is just to learn more about how dcraw works. Read the rest of this entry »
I have seen a lot of ubuntu people asking for a cinepaint version with printing support. I have done tests with the ubuntu linux live cd and a chroot environment. This way I am able to write down each step.
You need to install these packages. I prefer to use command line, and then the step is:
Recently I purchased an eye-one photo lt. With that set there was a scanner target included, named Eye-one scan target 1.4. Since I don’t have a scanner I took a quick test at my office. Linux is now very user friendly. On my ubuntu laptop I just had to run the command “sudo apt-get install sane” and there was the scanning software installed. I plugged in an Epson 3200 photo and started xscanimage, which is part of sane package. I put the target on the scanner and scanned it as a 16 bit pnm file.
I have taken a look at the statistics behind dcraw. I’m just thinking about how it grows in lines. Of course that is not a very good quality indicator, but it gives us an indication of the activity to Mr Dave Coffin.
I was going to make a screencast with audio comments about cinepaint and ufraw. Unfortunately I get a lot of trouble with the sound. Anyway I put it on the web with only text comment. There is other way to do this. This is only meant as an example. I could have spend more time in ufraw, and I guess on another image I would.
The reason I was thinking of making this screencast was to present how a 16bit colormanged workflow could be done in linux. There is a lot of people around complain that they can not use linux because of this. In this workflow even the printing is in 16 bit. I guess thats not very common in the windows world.
If the color looks very off, I guess the reason is that I have not profiled my laptop. My workstation is profiled, but it was easier to get the screencast software up and running on mu ubuntu laptop. I am using my workstation screen profile, just for the sake of an example. The video is in 800×600, which is an compromise between filesize and what is usable.
Dcraw is a very nice and high quality program. New versions are coming the whole time. It can however be quite hard to notice what is new in the latest version.
For a couple of years my workflow has been, download the current dcraw.c and use diff against my previous version. It works of course, but reading the output can be quite hard for a non-programmer.
That was the reason I wrote this shell script.
On my old website there was a howto for how to install Picture Window under linux.
I will add this content here to. You can read more about Picture Window on Norman Koren’s website.
