偷参考美学做真感写真

Prompt

how to generate ai photos that look 100% real with gpt-image 2.5

2.5 is a step up from 2 but it carries the same tells

straight out of the box with no reference you still get that ai look

so stop describing the aesthetic and start stealing it

find a photo that already has the look you want

drop it into gpt-6 astra and ask this

"analyze this photo and give me a very detailed json prompt describing its visual style. break down the color grading, the lighting and the exact colors so i can apply that look to my own images"

astra reverse engineers the reference into a prompt

you were never going to describe that grade yourself

take the json into gpt-image 2.5

attach your product and prompt

"using this json as reference, generate a person holding my product"

then generate the same thing without the json and put them side by side

the lighting and the grade are the whole difference

save the character you like

attach that photo on every future generation and ask it to preserve the same facial features

now you have a consistent person across your entire product library

want a different mood
go back to astra, iterate the json, run it again

the tells are almost always the same two things

flat default color and that plastic grain

so grade on purpose and check those first

the json controls the light
the character controls consistency
you control the product

that is a repeatable ugc pipeline instead of rolling the dice every time
