In AI Art, words generate an image. Modifiers are words which have an additional influence on the creation of the image. There are certain kinds of modifiers - some are descriptions which are used by photographers like "close up", "medium close up" and such, and some define the style of the image by using the words "by artist xy".
Just now I am experimenting with capital initial letters. Here are two examples. With the first one, I used the following prompt:
Beautiful painting of the Initial capital letter H,by artist "Chantal Misplon", art nouveau, decorative, intricate, hyperdetailed
With the second image, I used the prompt:
Beautiful painting of the Initial capital letter H, by artist "Salvador Dali", art nouveau, decorative, intricate, hyperdetailed
And what a difference between those two images!
