flux 官方 kontext 总结

Image Editing

Examples of Editing

Basic Object Modifications

FLUX.1 Kontext is really good at straightforward object modification, for example if we want to change the colour of an object, we can prompt it.

For example: Change the car color to red

Iterative Editing

FLUX.1 Kontext excels at character consistency, even after multiple edits. Starting from a reference picture, we can see that the character is consistent throughout the sequence. The prompts used for each edit are shown in the captions below each image.

• Remove the object from her face
• She is now taking a selfie in the streets of Freiburg, it’s a lovely day out.
• It’s now snowing, everything is covered in snow.

Text Editing

FLUX.1 Kontext can directly edit text that appears in images, making it easy to update signs, posters, labels, and more without recreating the entire image.

The most effective way to edit text is using quotation marks around the specific text you want to change:

Prompt Structure: Replace '[original text]' with '[new text]'

Example - We can see below where we have an input image with “Choose joy” written, and we replace “joy” with “BFL” - note the upper case format for BFL.
