I haven’t tried it yet, but one idea is to create a very detailed memory palace through the picture. If you have a location attached to each important detail, your mind should be able to remember it.
Check out the image below. I removed the color from the image so that the numbers would stand out. It is just an example so I only put 25 sample locations in it.
I was thinking about doing this for paintings, based on a couple of recent posts about using paintings as memory palaces. I’ve also been wondering if one could use a similar technique to remember specific locations in detail, like a room that one wanted to keep a strong memory of.
