subreddits related to r/atoptics
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.
/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/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!
/r/CrossView is dedicated to the stereoscopic free viewing method of cross viewing. Accepting submissions of all forms (pictures, gif/gfys, videos). If things look 'reverse depth' than /r/ParallelView might be the place for you! Full rules, 'how tos' and links to helpful apps [on the wiki](https://www.reddit.com/r/CrossView/wiki/index)
The best links to click while you're stoned! Psychedelic, mindfucking, mesmerizing, reality-distorting or trippy games, video, audio & images that make a sober person feel stoned, or stoned person trip harder! Come for mindfucks and self-inflicted gaslighting. Or the hypnotic or mesmerising. Vivid colors, intense patterns. Mind-blowing science and philosophy. Chill or trippy music. Surrealism, absurdism and strangeness. Reminder: This is not a "reaction subreddit".
This is a community of passionate photographers to work together to improve one another's work. Our goal might be described as making this a place geared toward helping aspiring and even professional photographers with honest feedback. We would like the information given here to be a tool to help those that are serious about their photography to improve.
