/r/ExposurePorn is a Safe For Work subreddit in the Safe For Work (SFW) Porn Network. The main focus of /r/ExposurePorn is to feature photographs that use the long exposure technique at night or during the day to capture stars, the milky way, movements, lights and much more! Great place to find astrophotography, HDR, long-exposures, light photography, and night photography!
SpacePorn is a subreddit devoted to high-quality images of space. As long as the focus of the image is of the stars or related to space in some way then it is allowed. This includes artwork as well as photography.
/r/photography is a place to discuss the tools, technique and culture of photography.
This is not a good place to simply share cool photos or promote your work, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.
/r/NASA is for anything related to the National Aeronautics and Space Administration; the latest news, events, current mission and future missions and more.
>Note: r/nasa is an unofficial forum and not representative of NASA or the US government
The aim of /r/Physics is to build a subreddit frequented by physicists, scientists, and those with a passion for physics. Papers from physics journals (free or otherwise) are encouraged. Posts should be pertinent, meme-free, and generate a discussion about physics. Please report trolls and intentionally misleading comments.
