Free Photoshop

Most used around the world, PhotoShop, graphic editing software saves inside infinite possibilities to improve our creations. With this advanced course we know free some of these options that will help you give a professional touch to your pictures. Adobe Photoshop has become the application most commonly used in the field of photographic retouching and excluding design, both for professional users such as fans, both PC and Macintosh environments, and that can only mean one thing: that you have made a good choice when he decided to learn how to use Photoshop and that time used in this will be an excellent investment. Photoshop is no longer a tool solely used by designers / layout, now Photoshop is a tool widely used also by professional photographers from around the world that use it to make the process of printing and digital magnification, not having already go through one laboratory rather than printing the material. The tutorial We disponibilizamos is very full, with 22 chapters dealing with all this fantastic tool can do. Download now our tutorial and be prepared for the very lucrative and competitive labour market of imaging!.


Aluminum is, like any other metal, sensitive to environmental oxidation process. This spontaneous process would produce random spots, which would negatively affect the aesthetics of the profiles. It can be defined as the process of anodized as a controlled, accelerated oxidation and uniform of the most superficial layer of the profile, through an electrochemical process. The process of anodizing can be divided into three basic stages: pretreatment (degreaser + pickling), Anodic treatment (electrochemical process in which the aluminum becomes electrically positive and is immersed in an electrolyte) and post-treatment (sealed), to increase resistance to stains and corrosion of that layer. Outlook Email oftentimes addresses this issue. Treatment of lacquer consists of protecting the surface of the aluminium profiles with a coat of paint applied, either in powder or liquid. The designation of “Quality marine” is a process that improves the performance of the lacquer in very aggressive environments as first line of sea, industrial, etc., which consists in increasing the recess of the the material surface of 0.8 gr/m2 to 2 to 4 gr/m2, which benefits the penetration and grip of the depositions, while the “Fluorocarbonatados” or “PVDF” (lacquer based fluoropolymer 70: 30) are systems multilayer that offer excellent benefits to the aging and degradation of colour due to UV rays in environments of high aggressiveness. Both profiles such as aluminum plates used in construction are exposed to some risk of corrosion, which not only can have aesthetic but also structural consequences. For galvanic couple corrosion occurs when two metals are put in contact and both have different electrical potentials, which favors the behavior of a metal as anode and the other as cathode. To prevent galvanic pair place separators of plastics between aluminum and other metals, such as stainless steel for the anchorages and wicks.
