It's just another way to play with photography and learn from others. It is written in Portuguese. Resume of the last articles in the blog: Wikimedia Commons Imagine a website with more than  100.000 images that can be used in other projects, by other persons and companies. Images that can be used legally, at zero cost, and without the need to ask permission; for commercial and non-commercial purposes. It's only required that you giver credit to the photographers or designers who produced the photos in the projects that include them. Some images can only be used in projects that are licensed under a specific license. Projects that grant this same rights to its users. Most images you can find in Commons are "information-type" images. It's purpose is to be used in encyclopedias, educational books and news stories. All images I post in the "Wikimedia Commons" are licensed under "Creative Commons", and they can be used to commercial and non-commercial purposes.  However they can't be used in projects under copyright that do not have a free license, one that is similar to the license I adopted. User page,  contributions Wikinews Wikinews is the open online newspaper where anyone can help. In Wikinews there aren´t opinion articles, and the news text can be improved by any user. Everything in  Wikinews can be changed by any user: texts, images and website design.  Like any other wiki-based website, if your contribution is not good for the project, it can be erased or changed by another user. User page, contributions Wikipedia The biggest online encyclopedia is free. Free to read, free to copy and free to improve its content. The Wikipedia does not show advertising, and it's an excellent source of information about everything.  Wikipedia works thanks to thousands of volunteers (297076 in the English language and 10309 in the Portuguese language) I'm just one more. 366 Photographs on the Beach Its a wiki book to select 366 photographs made on the beach, the selection criteria is mostly aesthetic. All the 5 continents are represented. Every photograph must have a free license, so it can be used for free in other projects either commercial or non commercial. However any project that uses them has to be licensed with a free license, and it has to display the photographers name.
