weight: -8.0 to 8.0 (or more)
positive: into the future
negative: into the past
High weights go forward, negative weights go back, like a time machine. One issue is that it cannot go back much farther than the 50s or 60s, unfortunately, there are just not a lot of pictures before then that SD was trained on, for whatever reason :). Pictures can also go greyscale or get orange. Add "monochrome" to the negative prompt to help combat that. Going forward, everything gets silver. Silver clothes, silver walls, etc. If you like my work, I'm not asking for coffee, but a good review is always appreciated.
