Tutorial: Enlarge an image with little loss using Gimp

final

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, 150x200 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.

The image is taken into consideration this, a fine example of a golden retriever adult.

As you can see the dimensions are very small, but now we will use G'MIC. Let's go over "Filters" - "G'MIC" and click on the settings "Enchancement" - "Smart upscale" with the following values.

The processed image will be twice the size and the loss you will notice, however,, but will always be less than the tool "Scala" .
