Adjusting the colors of images saved in the Photoshop Document (.psd) format and sharing these modifications, often along with related resources like actions, tutorials, or before-and-after examples, is a common practice on the Tumblr platform. These adjustments can range from simple tweaks like brightness and contrast modifications to more complex techniques involving curves, levels, and selective color changes. For instance, a user might post a .psd file of a portrait with adjusted skin tones and a softened background, alongside a tutorial explaining the process.
This practice facilitates the dissemination of knowledge and resources within the creative community. By sharing adjustable files, users enable others to learn advanced techniques, experiment with different styles, and adapt existing work to their own projects. This open exchange fosters collaboration and accelerates the development of individual skills. Historically, finding and sharing such resources required specialized forums or software; platforms like Tumblr have democratized access, creating a more inclusive learning environment.
