Nano Banana

 I asked Nano Banana to create versions of this photo:

And here are the results:

 

I was not pleased with the second photo because, by rotating the subject, it looked like a different kid, in my opinion. Here is the prompt that I used to get the first picture edited by Nano Banana.

"An expressive, natural portrait of a subject, bathed entirely in warm, directional golden hour sunlight. The light should be low, highlighting the texture of the skin and hair with a vibrant rim light. Camera/Settings: Captured on a Canon R6 with a 85mm lens, f/1.8, shallow depth of field (bokeh) in the background. Composition: Leading lines from a distant fence drawing the eye to the face. Style: Cinematic realism, saturated gold and orange hues, high dynamic range. Do not change subject position. Do not edit the face of the subject." 

In my experience, Nano Banana tends to always edit the face of the subject, which is the reason why I do not feel it’s a tool that can be reliably used for editing. However, you get decent results if you try to replace the background or use other tricks in that sense. If you do not put both pictures, the original and the one edited by Nano Banana, side by side, the results look nice, but if you compare them you can notice the AI editing right away. 

You can find other prompts and test them yourself here.
