photoshop generative verb urgent help for a problem?

[Ya??z_Yava?5869]

I urgently need help quickly. As seen in the video, I want to combine the man and the car in Photoshop. When I put the man in the car frame, it doesn't look realistic. I thought I could create a more realistic background by expanding the car image sideways, with the man inside. Perhaps expanding the car itself would yield better results. The first problem is, as seen in the video, when I expand the car photo, the man disappears. When I expand the man, the car disappears. How can I fix this? Could you explain it clearly? If possible, with photos or a video, I'd understand better. Thank you.Note: I couldn't upload the video, I'll send it as an ss.

Hey, @Ya?? z_Yava? 5869. Welcome to the Photoshop Community. While AI features can aid your workflow, you'll still need to start with a composition to achieve the desired results.

You can't just click a button and hope to make this work. You need to place the image of the person where you want it on top of the car image. You can try using the new Harmonize feature in Photoshop Beta to blend the images together. I'm not clear on where you want the person in the car image. Learning some traditional Photoshop editing will go a long way for you to make this look they way you want.
