FROM IDEA TO RESULT

What can you do with Black Forest Labs Flux 2 Flex?

Lighting, materials and texture

Specify the subject's material, lighting and camera angle. Guide the image toward a studio product scene or an atmospheric environment.

Composition and visual guidance

Flux focuses on detailed visual instructions and refined imagery. In image-input mode, build on a source visual; in text mode, specify object placement and style.

From text to an image

Start with an idea without a source image. Describe the subject, setting and style to develop an illustration or advertising visual.

Work from a source image

Use the image-input mode to work from an existing visual. For an edit, describe a specific change and identify what should remain.

Where it fits

Product scenes, advertising imagery, covers and concept art.

How to get a useful result

Use concrete visual details: light source, palette, lens or composition, rather than simply asking for a beautiful image.
