Stefan Bohacek Let's not limit this to only image descriptions in alt-text in toots from vanilla Mastodon.
How long is too long for an image description in general, regardless of whether it's in the alt-text or the post text? Or specifically when it's part of the post text? Is there such a thing as too long?
I'm asking because while I'm indirectly bound to Mastodon's 1,500-character limit for alt-text because Mastodon cuts everything that's longer permanently off, I'm not bound to Mastodon's 500-character limit for posts because I'm someplace very different from Mastodon. And my image descriptions tend to grow unimaginably long.
They have to be that long in order to be sufficiently informative. My own pictures are always from non-real-world places that nearly nobody knows, and so they only contain stuff that nearly nobody knows. And they don't always focus on one element so that everything else can be swept under the rug. So I have to describe a lot, and I have to explain a lot.
Let's just say I can no longer write full detailed and sufficiently informative image descriptions within Mastodon's constraints, not even within 1,500 characters. Even a carefully chosen camera angle that shows as few surrounding and background details as possible plus cropping away some more details won't let me stay within the 1,500-character limit.
Now, the thing is I hardly get any feedback for my image descriptions. Most of my image posts get none at all. Some sighted users say they're generally too long, but they never criticise any particular description of mine. Instead, they go by the character counts I tell them.
On the other hand, I've just received
praise from a blind user for
a post (content warning: eye contact) with two pictures and my longest image description to date: The preamble for both images has slightly over 1,300 characters, the description for the first image has almost exactly 40,000 characters, the one for the second image which references and relies on the former has about 6,750 characters.
Mastodon's alt-text police seems not to have discovered my posts yet, probably because none of them follows me. That, or they're perfectly okay with what I write. Without any feedback, I can't know. So I'm asking all of you.
