Replace Subject [Klein 4B & 9B]

Allows you to replace a subject in the first control image with a subject in the second control image.

The model will skew towards preserving existing details if the secondary control image does not include the relevant details and the prompt leaves them unspecified. For example, if you are using a head/torso image as the new subject, but the original image was zoomed out more and the person being replaced has jeans, the new person will also be wearing jeans unless you specify otherwise.

For best results, try to have comparable framing, camera angle, and number of subjects in both images.

replace the person in Image 1 with the person in Image 2
replace the man in Image 1 with the man in Image 2
replace the woman in Image 1 with the woman in Image 2

Model Comparisons:

• Copy Pose will preserve the subject and background in Control 1, while bringing the framing/pose of Control 2

• Replace Subject will preserve the framing/pose and background in Control 1, while bringing the subject of Control 2

• Replace Scene will preserve the subject and pose in Control 1, while bringing the background scene of Control 2
