Most of the projections are not geometry-critical so I think it’s just about projector placement and adjustment.
What's more interesting: what projector is it and how is it powered? It’s crazy bright for a portable setup.
Also, did you write this?
Please post more photos on the Fediverse rather than Twitter or Instagram.
Powering it is the hard part. I use a lithium battery in constant danger of melting.
Yes, I did write that. More to the point, I wrote a solarpunk mystery novel, which I’ll post about on Monday.
Given the great response, I will post more relevant projections here. What community tag should I use?
Still, what kind of projector?
You could try going old school and using something like a slide, overhead or film projector for static images (with a modern mercury/LED lamp): you’ll get 3x higher light efficiency than colorwheel DLP (color filters lose ⅔ light each) and 2x higher than 3LCD (prisms divide light efficiently but polarization loses ½ of it).
@AEMarling @ChaoticNeutralCzech The two in your projection are definitely appropriate, and are how I found your post. Maybe #GuerillaActivism and #ClimateCrisis. Be sure to use PascalCase for hashtags so that screen readers break them into sane words, and use alt text for your images :)
Why tag me?
If you look at their username thing, you can see that they're replying from Mastodon, not Lemmy. It's some weirdness Mastodon does that Twitter also does where it tags the person you're replying to and people tagged/replied to earlier in the thread you're replying to by default, unless you delete the tag before you post. Most people don't delete the automatic tags. So they probably didn't do it on purpose and may not have even realized they did.
It's how it works when you reply to a Lemmy comment from Mastodon. It will automatically tag the comment you are replying to and it's parent.
Still... software?
Most of them are static images, so... any picture editor?
