Tutorial: even out the color in a simple way with Gimp

And after a long absence due to earned vacation I'm back with a tutorial very simple for our program editing fotografico preferred: Gimp.

In this tutorial we will see how level colors of a photo automatically. It can happen often to extract from the album of memories some photos taken a few decades ago, which have now lost most of the color original and are dyed red or blue, or even green. Here are some examples.


“Print” time and date automatically in a photo

Today we are insert current date and time in an image using the terminal. By itself, the procedure is not complicated, let's see how.

Meanwhile, we see how to make us say the date and time from PC:

[user@localhost ~]$ echo $(date -R)
Tue, 24 Aug 2010 11:45:04 +0200

And now let's see how place it in the we are interested in using ImageMagick. This program allows us to perform many image manipulation, without having to go through the GUI. There is also a primitive graphical interface, but ImageMagick is mainly used for a number of automation (that soon we will see) command line, the invoked by PHP. (more…)

Tutorial: Newsprint retro with Gimp

Today's tutorial is very fast because the effect is Gimp's native. Transform a RGB image in un’indexed image in two colors: white and Black. This conversion will give the image a starting effect “newspaper“.

First, we open an image that lends itself. In this tutorial I will use a landscape, despite the portraits lend themselves more. (more…)

Tutorial: play with gradients Gimp

I gradients are a tool that beginners often ignorant of graphics tend to neglect because “difficult“. In reality, the gradients are a part fundamental graphics software, without it would be more complex to create shades and glows. In this article we have fun playing with some of the gradients default Gimp, we will see that they are simple to use and can help us to create simple, but effective effects.

Here are some pre-defined gradients of Gimp. It is enough to set the gradient mode of “Radial“. (more…)

The software for raster graphics

In this article I want to explain the advantages of graphic software “Pint“, but I let him go willingly to some thoughts that I bet I'm not the only one making. I will try to illustrate the problem (because of a problem is) as simply as possible.

The software “Pint” has just arrived (the 6 July) his version 0.4, a release is still immature when compared to the build number and characteristics of its alternative sia open che closed source. On Wikipedia inglese is written clearly that “Pint, inspired by, arises as alternative Gimp easier”. (more…)

Tutorial: da bitmap a SVG con Inkscape

Together with Gimp by image manipulation, e a Scribus for desktop publishing happens to me sometimes to adopt the use of Inkscape. Inkscape is a vector graphics editor, a program for the picture “screen”. It can be used in various fields, there are those who use it to draw company logos, or even for the illustrations of some books. Personally, I have many skills in this area, and I find that even a pencil and paper in many cases are the most expeditious (of course, from my point of view). More than anything else I Inkscape is useful for vectorization of raster images, I know that Inkscape provides several other functions and is a little’ simplistic to use it exclusively for this, but for now I have no other duties for him to perform.

Open Inkscape and import an image jpg: (more…)
