Some solution to protect your images on the internet

macro

Those who describe today are the most common methods that allow us to, in the event of litigation, of resolve the issue related to copyright images.

The International Law (to Berne Convention for the Protection of Literary and Artistic Works) states that the artistic rights to the work resulting from the ingenuity and creativity can be attributed to the people who made. Forever. This means that if today I compose a piece of music will always be my, I can decide whether to play it without receiving compensation, but the author is me and to me that specific work must always be attributed. The same mechanism applies to the photograph (on condition that the photo is understood as a 'artistic work).

Real HDR effect with Qtpfsgui

hdr

The software we are talking about today is Qtpfsgui, software for the creation of HDR images.

Often mistakenly tend to confuse with the HDR tone mapping, in fact for HDR (High Dynamic Range) means the overlapping of several photos taken with different exposures to allow the optimum setting for the exposure areas. To get a photo HDR is really required the resumption of same subject in same shot, each with a different light, For this reason, the HDR is possible only with still subjects (monuments, case, vegetable, still life, etc.), you can not apply it to moving subjects (people, crowded streets, animals, treni in corsa, etc.). To get the best from Qtpfsgui it is preferable to take pictures from a fixed point, better still if a tripod.

Some scripts for Gimp

cross_processingFX

Unfortunately Gimp not is still at the levels of its main competitor closed source. This somewhat 'I regret, and a little 'pushes me to look for solutions that approach a suitable level. One of the most annoying differences between Gimp and PhotoShop the lack of import / export curves between the two programs. Gimp saves the curves in a format similar to 'XML (as far as I know only readable by the Gimp, but standard), while the curves in PhotoShop save format ".asc" (a binary format readable only by PhotoShop and similar). The curves are one indispensable tool for every advanced user, but to this there is a small solution.
