One way would be to use the quick selection tool to create a selection of the product areas like the bronze and chrome area. With the selection active add a hue and saturation adjustment layer. Them use the properties to colorize it.
Adding to JJMack’s advice on using Adjustment Layers:
The images you posted are poorly fitted to automating the task in a significant way, I’m afraid.
You will likely have to do considerable manual masking because the chrome armature does not separate from the white ceramic very well.
And changing the image with the black product with the matt finish to a reflective-surface-appearance would probably be a pretty time intensive task.
Should your customers dare say something like »but to achieve this effect in Photoshop you just have to …«: Beware – your cutomers might not be willing to pay for the time the work actually takes because they don’t comprehend the task.
In any case getting the RAW images (or 16bit images from that originak data) might help as with extreme color adjustments working in 16bit can be beneficial.
Thank you for the reply. Automating the process seemed very unlikely for the get go. I wanted to see at least how to achieve this efffect and in what time frame. Your result is pretty good thou still not presentable as you know. I will play with it some more. As I understand, the client is willing to pay the cost, but I'd have to take it one step at a time.
