1. first do it vertically, this will help keep the results reasonable

if you don’t do it vertically, it might look too dramatic:

1. think about where to place the original image

   💡 doing it from the center, corner out, top to bottom etc. gives very different outcomes →

   

1. describe the expansion using text prompt

   • how to write a good expand prompt
     • the best practice is just to describe the full final image you want after the expansion
     • try to include more descriptive words about the style; AI matches the original style automatically, but it always helps
     • don’t put in commands like “extend this or that”; it might work, but is not necessary
     • throw in some magic words like “high quality” “highly detailed” “HD” “high resolution” helps too, craft the prompt just like how you create an image
   • iteration matters! if something doesn’t work perfect on the first try, check the result, revise your prompt, and try again

2. do it bit by bit for best quality and control

   

   

1. re-enhance the quality with ultimate upscale after expanding multiple times
