How to frame a coin
Taking good quality pictures of jewelry for most is an unsolved mystery. However, there are some simple techniques used by the professional, which even amateur photographers can use to obtain dramatic results with minimal effort. The following examples show the basic setup that should allow anyone to achieve results they can be proud of. These images were all taken using a Canon Digital Rebel camera with a 100MM lens.
The basic setup we used included an EZcube light tent to soften the shadows and eliminate glare, while providing a clean and clutter free background. We used TabletopStudio lights as the primary light source, equipped with true color daylight balanced compact fluorescent bulbs. We also used a special Diamond dazzler LED bulb to light up the diamonds and faceted gems in the example images on this page.
The keys to good jewelry photography are sharpness, lighting, exposure, and in the case of gemstone photography, creating some sparkle. Good jewelry photography needs sharp, crisp focus. It is worth getting out your camera's manual to find out how to put the camera in "spot focus" mode. The normal focus mode of digital cameras is some sort of average focus mode. That means that the camera will look at a wide area of a scene and base the focus on that area. Since you want to control where the camera is focusing, it's better for jewelry photography to put the camera into spot focus mode, this will allow you to control more precisely what the camera will be focusing on. However, even in spot focus mode many digital cameras can't really "lock-in" on a small shiny object like gemstone jewelry
using auto focus.So unfortunately, for close-up jewelry photography, you need a camera with good manual focus capability.
Another key to a sharp image is a tripod. It is absolutely essential to use a tripod or similar camera support when shooting jewelry. A sturdy tripod is better than a flimsy one, but any tripod is many times better than no tripod. Use a tripod.
Another key to good jewelry photography is the lighting. Normally diffuse (soft) lighting works best for jewelry. You have probably already discovered that an on-camera flash does not lead to good jewelry photos. Not only is the camera's flash too bright at such a close distance, but it is probably in the wrong position to actually light up the jewelry properly. On camera flash will also create harsh and distracting shadows. Rather than flash, we like to use continuous lighting for product photography. Using continuous lights makes it easier to visualize what the final image will be like.
We prefer daylight balanced compact fluorescent bulbs for lighting. These bulbs provide nice, natural-colored light and they produce very little heat so they can be left on for long photo sessions without over heating the photographer. Even fluorescent light bulbs will need to be diffused and for that we use an EZcube light tent as the diffuser. A small light tent makes it easy to reduce glare and control shadows for jewelry photography.
Proper exposure is also key to good jewelry photography. (For more information on adjusting the exposure for jewelry images take a look at this page .) Now lets look at some specific jewelry photography situations that go beyond the basics.Source: www.tabletopstudio.com
