Pixlr
Recently, when writing a blog on someone else's computer, there was a need to crop and add a watermark to an image, but the computer didn't have the graphic design software I was familiar with. Downloading a full Photoshop would take too much time and the laptop probably wouldn't have enough battery, and it felt inappropriate to install other simple photo editing software on someone else's computer. Some of the less commonly used, non-mainstream software also required time to explore. The situation was not efficient at all. Then I thought of Pixlr, a website that simulates a Photoshop software, which can be opened directly using a browser. Its features and configuration are almost the same as Photoshop, with a Chinese interface and a 0-second start-up time. After uploading the image, editing can be completed quickly, making it a very convenient tool website. It is a must-have for designers who are out and about, traveling at home, or in case of emergency.
Google Art Prject
Google established the non-profit Google Cultural Institute to provide museums around the world with free digital archiving technology support, such as 360-degree virtual reality, street view services, digital content management, film or recorded guided tours, and even assistance with translations in multiple languages. It also helps museums produce mobile apps and provides search engine technology support services. Some people may think museums are outdated, but when they see the online collections, who will come to the museum? However, the idea is that by releasing resources for more people to see, the museum's reputation will grow and more people will be willing to buy tickets to see the real artifacts. As a result, museum ticket and souvenir sales revenue will increase. Currently, there are over 4 million artworks available for download and use.
