I tried to make a Gemini 2.5 portrait look like an actual photo
Generated about thirty portraits in Google AI Studio with Gemini 2.5 Flash Image (the one people call Nano Banana). Composition was perfect every time. The faces always read as AI inside two seconds: shiny forehead, no pores, eyes too symmetric, a strange uniform softness across the whole skin.
Tried Topaz Sharpen AI. Made it look like over-edited Instagram. Tried Magnific. It changed the face. Tried just dropping film grain on top in Photoshop. It just looked like a noisy AI face.
What actually worked: I ran the Gemini output through NanoFace Vivid (the online demo at the time, sounds like it is integrating into the NanoPocket FaceSwap Pro 2.0 desktop app soon). It only touched the high-frequency band — pores, lash detail, micro-shadows under the cheekbones. The face shape and identity stayed identical. After the pass it stopped reading as AI to anyone I showed it to.
If you are stuck with the same problem, the trick is to use it as a final post-processing step, not as a replacement for the generator. Generate in Gemini, finish in Vivid.
