I found this from some where. It's from a bro. Let's call him Bro Sebastian.

For camera system, such as Canon system, both the Canon 60mm and 100mm marco lens are very good lens. Coupled with the current DSLRs in the market, it's a formidable weapon.

First of all, where equipment setup is concerned, ideally would be to be able to use a marco lens since it allows a shorter minimum focusing distance. You'll find that using a normal lens will only allow you to focus on your amulet successfully till a certain distance away from your amulets. Any nearer will result in your lens being unable to focus properly to achieve a sharp image. There is nothing wrong with the lens, just that different lens have different min focusing distance. If you do not have a macro lens, you can still take the picture, though the amulet will appear small in the photo. You can then proceed to crop the amulet image portion in photoshop which will "magnify" your amulet image, but this is best done using high Megapixels camera since you're actually cropping away pixels when you crop the image.

Next is how to achieve a sharp image. To do this, a tripod is a must after being able to get a proper focus on the amulet. Besides using a tripod, use the self-timer function on the camera body itself to avoid handshake, even if the camera is mounted on a tripod. If you're using a DSLR system, a remote cable release will be best. Else, the self-timer function can do as well.

Last but not least, proper lighting is essential in order to get the closest color of the amulet you're shooting, as room light is normally projected from the top and will cause certain areas of the amulet to be in shadow areas. For a start, you might wanna experiment with window light, preferably in the morning, as the light is softer. If you find your flash light too strong, you can either tune down the strength of the flash or use a tracing paper / tissue paper etc, to cover the flash which acts as a diffuser to soften the flash. Personally, i've not used a light-tent before hence i have no experience in that. A light tent looks like this: http://www.obnphoto.com/light_tent.html. Alternatively, you can DIY:http://digital-photography-school.co...ive-light-tent.
Using a light-tent will require you to play around with the lightings to achieve your desired result.

Hope it might help you to take better amulets pictures. Amulets photography (if there's such a term), is actually the same as product photography in the photography field.
