Alright, subtoot time, but positively so.
A friend of mine with significant visual impairment pointed out that the lack of description on images is a cultural problem on Fedi, not an individual failure.
So, let me do a thing to help build that culture.
How I Do Image Description
I close my eyes. I look at the image first, and close my eyes. Then I try to describe it without looking. I find this focuses me on the important things to get the image across, without getting distracted by unnecessary detail.
It's okay to peek. I have a strong visual memory, so I'm good with one look, but not everyone is. But do try and see the picture in your mind, if you're not aphantasic.
If you are, I'm not sure if I know a way to help. I apologise; I don't know enough about it to know yet. I did want to acknowledge that not everyone can do this approach.
Anyway, that's my contribution today to creating a culture of image description.
What can you do to add to it?
