Chapter 14: Taking Close-Up Photos for eBay
Set Up the Camera for a Close-Up
1. Set your camera to its most manual setting. Ideally, you want control over aperture, shutter speed, and exposure value.
# Setting up the camera for a close-up is critical. This is one case where automatic settings can work against you. Manual settings provide the most control for setting up close-up photos.
2. Adjust the Aperture setting to increase or decrease depth of field. For eBay pictures, you want the depth of field only as deep as the picture. The background should ideally be out of focus to concentrate attention on the item for sale.
? Aperture refers to the iris the adjustable opening behind the lens that regulates the amount of light that enters the camera to create '' ','' The aperture size is expressed as f-stops (f16, f8,
f4, f2, and so on). As the f-stop numbers get smalller, the iris lets in
twice as much light as the next larger f-stop, which increases the depth of field and brings the background into focus. A larger f-stop setting results in reduced depth of field, which blurs the background. Compare Figures 14-1 and 14-2 for an example of reduced and
3. Adjust the shutter speed, if necessary.
# Shutter speed determines the length of time the shutter remains open and allows light to enter the camera to expose the digital film. Shutter speed is expressed in fractions of a second (^oth of a sec ond, J6oth of a second, and so on). When you shoot a bright subject,
it requires a shorter exposure time or a faster shutter speed.
4. Adjust the exposure value, as necessary.

Set Up Lighting for the Item
Set Up Lighting for the Item
1. Prepare the lighting for the object that you're shooting. You want the lighting to eliminate shadows from the object as much as possible.
2. Distribute the light evenly. Evenly distributed lighting reduces shadows that can obscure details of the item. Some methods of distributing light are
Fluorescent lighting: Using multiple fluorescent light sources provides good light coverage and can help to eliminate shadows. Fluorescent light, as shown in Figure 14-3, is more diffuse and less likely to reflect back into the camera than an ordinary bulb light. Aim light from as low an angle as possible to minimize reflection into the camera lens.
Diffuser: You can also devise a simple diffuser by suspending thin white muslin between the light source and the subject. If you're using a copy stand or have a set-up shot, you might make a tent of the muslin to assure uniform diffuse light.
If you're shooting outdoors, you can light the subject by reflecting sunlight onto the source using a piece of white cardboard or foam core. Have a friend give you a hand with this.
3. Use a flash to bring out the color, texture, and detail of the item.
Keep in mind that use of a flash increases depth of field and that a camera flash can overexpose close-ups and cause impossible glare on reflective subjects. If you're doing much close-up work and your camera allows lens attachments, see if you can get a ring flash attachment, as shown in Figure 14-4, for your camera. These are designed especially for close-up flash photography.

Use a Copy Stand to Support the Camera
1. Mount your camera on the copy stand, as shown in Figure 14-5.
A copy stand is ideal for shooting close-ups of objects. It holds the camera steady and in the proper orientation. It also creates a uniform set-up for multiple pictures and speeds the process.
If you don't have or can't borrow a copy stand, you can use your tripod turned on its side. Another option is an inexpensive tabletop tripod. You can successfully substitute a tripod for a copy stand when shooting small objects. See Figure 14-6.
2. Align the copy stand so that it's perpendicular to the copy board (the base of the copy stand where the object is placed) and the item being photographed.
Many copy boards have gridded backgrounds and require a cloth or paper cover to give the final background for your photo.
3. Shoot test shots and experiment until you have the distance, angle, and focus perfect.
eBay is a great place to watch for copy stands. Copy stands with lights are usually much more expensive than stands without lights.
