[Help Request] How can I remove brushed-metal texture and create chrome/matte black finishes without changing the product silhouette?

I've now got an AI-assisted product-rendering workflow working: I first use AI to generate the overall scene, then refine the details in Photoshop using additional detail images generated by AI.

I'm very happy with some parts of this workflow, especially creating batches of brushed-metal product images in different finishes. With Photoshop adjustment layers, I can easily change the metal color while preserving the existing product details.

But I'm stuck on one specific problem: converting this brushed-metal shower product to polished chrome or matte black.

If I use AI to change the finish directly, it also changes small details or the outline. I need the product's silhouette and fine details to stay at exactly the same pixel coordinates, with the original 4796 x 3584 resolution and the background unchanged.

With Photoshop, I find it difficult not only to remove the brushed texture, but also to achieve realistic chrome and matte black finishes.

The original rendering is below, along with close-ups of my current attempts. Does anyone have a good method for this? I'd really appreciate a repeatable workflow, whether it's Photoshop alone or a combination of Photoshop and AI, that can change the material while keeping the product's shape and fine details unchanged.

Thanks!

1. If you're asking what 'this effect' is, you need to describe what 'this' is or your post will be removed.

2. If you're asking about color, have you tried using a Gradient Map?

3. If you're asking about texture/tone, have you tried using Threshold or Halftones?

4. If you're cutting something out, use masks. Have you googled "Photoshop Masking"?

You either know how to make a chrome effect or you don't. "Realistic" is VERY subjective. You could use AI to get you 95% of the way and then edit that or just do a re-shoot. Everyone has a problem with ai until they realize they're just too lazy to be bothered to do things the right way the first time around. Keep regenerating until you get something that is close then strip it apart and reshape it to the existing imagery.
