Tutorial: Effect “macro” a panorama with Gimp

Today's tutorial is a cross between photography, graphic and Mathematics. Photography because we start from a real photo, and a good photograph is the beginning of a good job, graphic because of the various tweaks that as we make any and Mathematics because the effect scomoderemo today follows strict mathematical rules, nothing is left to chance. For this tutorial we will use Gimp and its plugin MathMap. (more…)

Import tracks from Inkscape, Gimp

Anyone with intellectual honesty would not hesitate to affirm that the level of interoperability reached from the Adobe suite (the manner in which they interface between their programs) e di Gran go top compared to open source alternatives. An example is importing tracks the Illustrator a Photoshop, possible by the classic copy – Paste.

Today's article, however,, not meant to be a criticism of the lack of communication between the developers of several open source projects, intention is to demonstrate how it is possible (in a way perhaps slightly longer) the same import operation paths between Inkscape and Gimp. (more…)

Tutorial: Enlarge an image with little loss using Gimp

The tutorial Today is one of those simple tutorials that are exhausted in a passage. More than a tutorial would call advice useful to remember.

Let's say you have a picture medium / small, not suitable for printing, we want larger than twice. Until today I expanded work space with “Picture” – “Scale Image” and inserting the double values, but I just recently discovered a way to resize them in excess with a higher yield using G’MIC, the plugins that we had already discussed, that does it all.

Let's say you have a picture very small, 150×200 px. Of course we all know that is impossible to enlarge a small image without loss, and even this procedure is not without loss of information, on the other hand applies the small improvements to “simulate” magnification without loss. (more…)

Photography: techniques for the reduction of “Digital Noise”

In today's tutorial we talk about photography. How many times has it happened to take pictures, affect them on the display of the camera and see them in good condition, then download them on the computer and realize the presence of the noise in the picture.

The digital noise present in the photo is the deterioration which can range from small disturbance barely visible, the disturbo “a puntini” very annoying to see how we will see in the next image it shows how the quality of the image may change, changing the ISO. (more…)

Change the dpi / ppi of an image with Gimp

I often find myself having to create images that serve as separator content within prints, or some simple graphic effects created with tracked, or with letters. I'm thinking of something very simple, that surely even in the old schoolbooks we were used to seeing without realizing.

Occasionally, however,, I happen to create the new image, save, and realize that the work is finished the dpi is too low Gimp because those who apply by default are 72, excellent to the web but too little for a detailed Print quality. Today we see how increase the dpi of an image we have already saved with Gimp 72 dpi, and the portarla 300 (great for Print). (more…)
