Can I link to my own photogrammetry tool or portfolio?
Only if the post itself is about photogrammetry, like a workflow, a model you captured, or a question, and it does not read as blatant spam.

Rule summary
- Posts must be related to photogrammetry: Please make sure your post is related to photogrammetry.
- No blatant spam: Please do not post blatant spam.
Works well
- Sharing a textured 3D model you captured, with the photo count, capture setup, and software used in the post.
- Posting an article about new photogrammetry software or techniques, with a sentence on what you took away from it.
- Asking a specific question about your capture workflow, like how to handle reflective or thin objects.
- Showing a side by side of a difficult scan, what went wrong, and what you changed to fix it.
- Linking a video walkthrough of a photogrammetry project and answering technical questions in the comments.
Avoid
- Posting a bare link to your product page with no photogrammetry context or discussion, since that is textbook blatant spam.
- Writing a post that is really about your marketing, your agency, or your funnel, which fails the photogrammetry relevance rule.
- Dropping the same promotional link across many communities, which is the pattern the “No blatant spam” rule exists to stop.
- Sharing content that only tangentially mentions 3D, like generic 3D printing or gaming posts with no capture or modeling angle.
- Repeatedly pushing your own link in comments without contributing real answers to people's questions.
What r/photogrammetry Is For
This community is for people who share and discuss 3D photogrammetry modeling, which is the process of converting a series of photographs into a textured 3D model. The description says links to models, images, articles, and videos about photogrammetry are highly encouraged, so this is not a link-hostile place. It is also a place to ask questions or share opinions on anything related to 3D photogrammetry. The stated goal is simple, a spot where people help each other out. That tells you who posts here: hobbyists, practitioners, and curious people who care about the craft itself, not about being sold to.
Rules That Matter Before Posting
Two rules decide everything here, and both are short. The first is “Posts must be related to photogrammetry”, which means every post has to connect directly to turning photographs into textured 3D models. The second is “No blatant spam”, which is the rule that decides whether a marketing-adjacent post survives. There is no rule against links, in fact the community description encourages links to models, images, articles, and videos. So a link is fine on its own. What gets you removed is a link that exists only to sell something with no real connection to photogrammetry.
What To Post
A good post here is a link, an image, a video, or an article with a real photogrammetry story attached. If you build a tool in this space, show a model you captured with it, explain the workflow, and invite people to ask questions. If you write about a technique, share the article and explain what you learned from it. Questions are explicitly welcome, so asking how to improve your capture setup or which software handles your use case is a genuine contribution. The description even asks for opinions, so a short writeup of what worked and what failed on a real project fits the room perfectly.
What To Avoid
The obvious failure is blatant spam, a post whose only purpose is promotion with no photogrammetry substance behind it. The second failure is drifting off topic, because posts must be related to photogrammetry and nothing else counts. If your post would still make sense in a general 3D or marketing subreddit with photogrammetry removed from it, it does not belong here. Anything that reads as excessive self promotion rather than helping the community is against the spirit of both rules.
