I have encountered more image descriptions on Mastodon in 24 hours than I have in Twitter in a couple of years. Seriously. I'm not exaggerating.
As a blind person, this means a lot to me. If you read this and you describe your images, thank you so, so, so much on behalf of all of us. If you don't, now you know you'll be helping random Internet strangers make sense of your posts by typing in a few more words than usual.
@pyredrid I can send examples later if required, but for now here's a short explanation:
When writing a description, consider what message your image is trying to convey. If you're posting a pic of the amazing cake you made, you'll obviously want to focus on what type of cake is it and how tasty it looks, rather than the bit of wall you accidentally captured in the background. With a painting, you'd focus on its contents, mentioning the type of paint used only briefly -- unless the paint and style were the focus. So on.
Don't be afraid to be less than objective. You aren't writing these descriptions for newspapers. The Fediverse is humans interacting with humans. Trust me, we not only don't mind, but genuinely want to read about how cute that thing your pet does is.
But if objective descriptions are more your thing, those obviously work well, too. Write what you know and enjoy.
A fun, happy little Mastodon/Hometown instance. Join us by the fire and have awesome discussions about things, stuff and everything in between! Admins: @Talon and @Mayana.
