This is what you see a lot of on ebay and other websites of people selling metal objects. My examples are using my Yamaha YTR-734 Silver Trumpet, which I pulled out and started playing again.

After cleaning it up I didn’t want to waste not preserving this for myself.

You would think just putting a metal object like this Silver Trumpet on a blue background and using two off the camera flashes at 45º angles (like copy stand) would give you perfect light. This is how this is lighted.

Here is the setup for the photo above.

I have two hotshoe Nikon Speedlights (1 SB900 & 1 SB800) lighting the trumpet. They are setup like a typical copy stand photo shoot. Works great for objects other than metal. Perfect for copying flat art work and books.

This is the same photo as above with just the room light and no flash.

This is the available light without the blue background

By removing the blue fabric the white table wrap the light around the metal and give it more shape.

Two flashes

My recommendation is Tent Lighting

Here I am using tent lighting. I pulled back the front panel so you could see inside.

When you wrap an object with light all around it you get much better results.

There are four flashes lighting this setup. Two Alienbees B1600 up in the ceiling pointing towards the back and two on umbrellas as you see here.

This is the setup with white seamless background.

I think you might do a better job of selling this trumpet on ebay with lighting like this than the light above.

Notice how in the bell the blue fabric is reflected. if you look really close you will see just a little black spec. This is the camera peaking thought the front panel.

Here the only difference in the above photo is using a blue fabric.

Somewhere in between?

Maybe you want something in between the top photo and light wrapped all around the object. Instead of tent lighting just use white foam board and cut it into different shapes. You can then put a black sheet out of the photo but blocking light. Then just place the strips of white foam board to place you want to add white verses the black. Slowly you can give different looks. Use different color foam board and you can add color to the reflections like the blue fabric is doing here, but just put it outside the view of the camera but in the reflection of the metal.

Rather than me showing you everything, go photograph something yourself and see what you come up with.
