Real-world Evaluation: Gemini 3 Pro Image vs. Photoshop vs. Jimeng

No amount of theory beats one real-world battle. I needed to create a promotional poster for my web video player project zwplayer. Here's the entire process.

Round 1 Challenge: A Photoshop Newbie's Attempt

My Photoshop skills are really limited; this is already my third version, barely passable.

Round 2 Challenge: Jimeng AI's "Understanding" Deviation

Next, I tried the popular domestic Jimeng AI. The generated image had some tech feel, but many detail issues: for example, characters like "全" (full), "多" (multi), "能" (can), "低" (low) had circled characters that were inconsistent and chaotic, plus obvious watermarks and AI logos. After downloading, I'd still need tools to remove them, and even paying to remove watermarks leaves the AI logo. This means I'd need extensive secondary modifications, completely beyond my PS capabilities, so I had to give up.

Final Showdown: Gemini 3 Pro Image's "Stunning" Performance

With anticipation, I uploaded the original image to Gemini 3 Pro Image and started conversational editing. The entire process flowed like water, almost without obstacles.Result 1: Perfect Fusion of Tech Feel and Professionalism

Result: Beyond expectations! The generated poster not only has excellent visual effects but is also watermark-free, ready to use immediately after download without modification. This completely changed my view of AI image tools.

Revealed: My Conversation Process

Such excellent results came from surprisingly simple prompts. Here's the complete conversation text version, feel its "understanding" ability:

1.  **Me:** This is a promotional image for the zwplayer js web player, please optimize it.
2.  **Me:** Keep the logo unchanged, fitting video playback characteristics, with a tech feel.
3.  **Me:** You are a design master, please further optimize the following text "Make video playback easier Full Protocol/Easy Integration/Multi-functional/Low Latency/Zero Cost".
4.  **Me:** Do not change the text content, only adjust the text effects.
5.  **Me:** The meaning is right, please design another one.
6.  **Me:** Beautiful work, you can do even better, make another one.

The entire process was like communicating with a top designer; it always precisely gets my intentions.
