You can simply add year, decade, era or Analog Photography as keyword to the beginning of your prompt and that will alone bring that retro look you’re looking for, you can always combine this with Cinematic effect by adding Cinematic keyword to the beginning of your prompt.

Basic Prompt:

Try the 80s, 90s, futuristic or any era that you love.

Now, let’s look at how we can advance retro look of our AI Photos by adding more details in Molecular Level:
