Question

Two things I don't understand about generative fill

  1. Why does GF hew to the color of the central objects. For instance, today, I have an old photo of two people dressed largely in blue. I requested a fill behind of “white curtains,” but the curtains are generated as blue. Why does GF not allow me to choose what colors I want?
  2. Why does GF usually misspell words? 

Why can’t I dictate what will be generated and have GF simply follow directions properly?

    I just generated the attached images in Photoshop using the following instruction:

    A man weating a t-shirt which says "Video extravaganza"

    Wow, that’s terrible, lol. Which models are you using? I tried it this way. I started with the photo of the man, selected his shirt, and used this prompt: Change shirt to a white t-shirt with the words, "video extravaganza" stacked in two equal lines. (It didn’t really get the “equal” idea but it got the spelling correct.) When you prompt with words “which says” it might be confusing. Try “with the words” instead when you want something written.

     

     

    ETA: It didn’t stick to my selection very well, especially the sleeve on the right, and that’s another problem.

    @nicmartJust as a test, I was able to achieve both of your requests the first time trying using the FLUX.2 pro model. To get spelling correct, try putting the words you want in quotation marks. The original curtains were sort of crooked, so I added the word straight to the prompt, but I still think they are a bit crooked. Note, I did save the file to PSD from WEBP, but that might not make any difference.

    GF created the crooked curtains that are not white. I posted an example of GF lettering per a simple instruction.

    And it did not hew to the color of the central objects in my test.

    WILD guess -- what is the color in the set foreground color box?

    -editing to add-

    `My a-HA moment fizzled; FG had no part to play in my experimenting.

    Try #1: my prompt in Edit>generative fill was “fill oval.” NOT oval, but the right color [after sampling a dough coil to make the FG batter-colored]

    Try #2: no prompt in Edit>generative fill resulted in the appearance of an impish child in blue.

    Try #3: Edit>generative fill prompt was one word, “fill.” It duplicated the dough spiral.

     

    Next contestant.

    I’m afraid that bears no relationship to the issue I raised. In this case I selected the subject, which included the entirety of both people, inverted the selection, and told generative fill to create white curtains. The result is not the exception, it is the rule. GF ignored my color choice and chose to complement the blue. Why did it not follow my command, which was not very challenging?

    @nicmart 

    It seems to me you’re misinterpreting the original problem.

     

    The problem here isn’t that the curtain is “blue”. The problem is that the photo is so severely underexposed that there are no whites here, it’s all muted to a middle gray value. And then an overall blue color cast becomes very obvious.

     

    In short - you don’t need any generative fill here. It doesn’t solve the problem. What you need here is simply a few tone and color corrections, applied globally:
