Again, given the fact that these text objects exist in a "virtual" domain, the surroundings that they will reflect can generally be anything you want.

To achieve the 'complex' chrome effect you see in the 1st and 2nd text objects at the top of this page, all you have to do is Duplicate the "Grad 3" layer and apply the Curves filter to it. There is virtually an unlimited number of settings that will produce a good, complex chrome reflection effect. I suggest you simply open the filter and try a few settings to see how it can effect the gradients properties. And remember, let your own eyes tell you when the effect looks good or not.

The 3rd example image above has a photo in it's reflection that is giving it most of it's colour. A photo or texture pattern layer should be put at the top of the layers palette.
All i did there was crop a photo i had down to a size that would fill my text. Then i pasted it into a Duplicate layer of the text. If you try this, be sure to click on the 'Preserve Transparency' box first before pasting. In my image here, i set the layer's Blend mode to Color Dodge and dropped the Opacity down to 60%. Try it with some background texture patterns too. Experiment!

And that's it!
Pretty simple wasn't it?

Just be sure that each time you create a new duplicate layer, you stop and take notice of how it changes the look of the effect. That's the only way you'll learn how & why my way of doing this effect works.

to the Top

To give your shiny objects a 'gleaming' effect you will need to add 1 more layer to your collection.
Duplicate the "Black" layer and move the layer to the bottom of the palette, right above the Background layer. Hit Ctrl + I to invert the black text to white.
Name this layer "Gleam".

Apply a 1 to 1.5 pixel Gaussian Blur to the layer. Then set the layer's blend mode to Color Dodge, and drop the opacity down to 60% or so.
Now click on the Move tool and use your up arrow key to nudge this layer about 1 to 3 pixels, depending on how much of a 'gleam' effect you'd like your object to have.

Needless to say, if your object is on a white background the 'gleam' effect will not be seen against the background.

TIP: Try adding a sparkle or two with a sparkle brush to really make your text and other objects shine.

Variations:

There are a large number of changes that you can make/add to certain layers that will produce some interesting variations to the effects you see at the top of the page.
Like this variation for example:

Here's one hint: one of the new layers has a 2 pixel outline of the text, and it's layer Blend mode is Difference.

No matter how you change the effect just remember that there is no one way that is or looks 'better' than another. This type of shiny metal effect can be very subjective. Which means that it's all in how you look at it as to whether it looks right or real to your eyes.
No one person can say that they have looked at shiny objects from every possible angle, with every different type of lighting situation that can be applied to these objects, so don't try so hard to 'reproduce' an exact effect.
It's more important here that you try to get a handle on how and why these effects can be achieved with Photoshop. After that, there'll be nothing stoping you from creating anything you can think of!
Whether it be real or unreal.

One charateristic that is missing in the examples here is a beveled or rounded edge. To create this type of effect realistically with chrome takes a lot of thought and know-how. Because it would be a somewhat lengthy subject to explain thoroughly, i will not be explaining that aspect of this effect here, but instead, hope to be covering it soon in the near future in a new section of my site devoted specifically to text effects.
For now, i hope the information here will keep you all busy for a while. ;?)
