Editing photographs in CinePaint

After having been tired of the comparably low quality the Gimp 2.6.7 offers, about one week ago I stumbled upon a .deb file1 of CinePaint 0.25, and much to my surprise, it worked! (In the past, making CinePaint work under Ubuntu was sort of a challenge: often, there were no appropriate .deb packages available, and when compiling CinePaint from source I often ran into problems with the color management.) Now I’m in the process of applying the bitmap editing techniques I used to use with the Gimp to CinePaint. About the main issue are masks. While mask handling using the Gimp is a bit difficult, it is even more so in CinePaint. But: the reward is the really impressve quality one experiences when working with CinePaint. (I usually work in 8-bit mode, although CinePaint offers up to 32-bit color depth/channel.)

Since CinePaint is an application for retouching film, the requirements are somewhat different from those of say, Photoshop. One thing, though, I would really love to see in CinePaint is the possibility to tweak an existing mask. (And, maybe, a quickmask mode. 😉

When starting CinePaint, it becomes immediately apparent that it is targeted at pros. The interface, somewhat resembling the one of Gimp (CinePaint evolved out of Gimp 1.0), is stripped of anything unnecessary; the filters available are stripped down to the absolute essentials: blur, gaussian blur, motion blur, sharpen, unsharp mask, two noise filters, and a few others. But–unlike the Gimp–CinePaint offers, as I said, up to 32-bit color depth/channel (including HDR), proper CMYK, and a well-designed color management system, afaik based on LittleCMS.

CinePaint is currently available for Linux, MacOS X, and BSD. Additionally, a tarball is available, in order to compile CinePaint from source. (There used to be a version for Windows available as well, and, according to the information on the CinePaint web site, will be availabe again sometime in the future.) In addition to the current version (the ‘Film Gimp’ version, which is based on GTK 2) , a new version named ‘Glasgow’ is under development. Unlike the ‘Film Gimp’ version, ‘Glasgow’ is based on FLTK and will consist of a number of different applications (see the overview on the CinePaint site).

To sum it up, due to the really professional approach and the clear interface, CinePaint is one of my favorite graphics apps. I’m especially curious how the new ‘Glasgow’ version will evolve.

Bitmap editing in Inkscape

bitmap, edited using Inkscape

This is an attempt of mine to use Inkscape 0.46 for bitmap editing. I got the idea for this sometime last year, and I already posted a few attempts of mine on Flickr. The reason for all of this is, that the handling of the bézier curves in Inkscape is so amazingly intuitive that the idea for using this for bitmap editing came kind of automatically, after I had imported a few bitmaps into Inkscape and tried out different things. (I actually cannot exactly recall when it occured to me that Inkscape has possibilities for bitmap editing, but I guess it was when I trie d to to edit a few of my own photographs and had to realize that the possibilities of the Gimp where somewhat limited for the things I wanted to do.

Here’s just one example of a task that is a bit challenging when trying to use the Gimp:

The problem is that the clone brush doesn’t work so well because the transition between the different brush strokes is not as smooth as it should be. In Inkscape, though, I found a feasible solution for this by using gradients. By superimposing several circular gradients over one another & then fine-tuning the result in Gimp (read: adding some noise and using the clone brush a bit here and there) I was able to get satisfactory results. (At first—before I decided to use Inkscape—I even gave CinePaint a try, but although the brushes in CinePaint are of far better quality than in Gimp, the look of the edited areas was not as smooth as I wanted it to be.)

After trying some basic bitmap editing, I went one step further & used Inkscape for things like additional eyelashes, eye shadow, and lip gloss.

Then, still one step futher, I painted some floral vector pattern on top of the respective bitmap & exported the result as a PNG.

Yesterday I made a new discovery: that it is possible (and comparably easy) to use Inkscape as a vector paint app, similar to the—as to my knowledge discontinued—paint* by discreet; only that the strokes in Inkscape cannot be animated that easily. (Basically it is feasible, though, to animate SVGs by using a language such as JavaScript.)

What would I not give to have CinePaint available as a .deb package for the current Ubuntu 10.04. Alas, it is not meant to be (yet). A while ago, I posted on this to the Cinepaint-users mailing list, but got no response.

For those who are not familiar with CinePaint and its capabilities: CinePaint is a deep paint program actually designed for editing film, but it can also be used for photo editing. The present (Film Gimp) version evolved out of the Gimp, but due to some controversy, the developer teams (for Gimp, and Film Gimp) went their separate ways. Currently , the CinePaint developers are working on a new CinePaint version named Glasgow, which is based on FLTK instead of GTK.

CinePaint offers up to 32-bit/channel color depth, color management, and CMYK support.

Comparing colors made easy

At CopySense, I found a nifty little online utility by which one can easily compare two colors in the RGB color space. One can even increment or decrement the hex values of each color. Besides that, there’s a number of other useful utilities available at CopySense.

Btw, Martin Latter, who runs CopySense, does some really fascinating graphics work (see the following article at Computer Arts to learn more). He basically uses the open source program StructureSynth, some additional open source apps, and Sunflow, an open source global illumination renderer.

FMX 2010: surroundings

Like last year, here’s a map (PDF) of the surroundings of FMX 2010, since I thought that this could be helpful for people not familiar with the surroundings, when they want to check out the possibilities of downtown Stuttgart, between talks or in the evening. I’ve marked a number of venures here, such as cafés, Starbucks, snack bars, pizzerias, etc., which are within close walking distance.
