The first thing that you want to consider when using a photo light box is the quality of the bulb. The best bulbs should be bright. Use the same type of bulbs that produce the same level of brightness.
If you want to achieve a shadow effect, ensure that you use a single light and place it one side. This will cast light on one side of the image.
On the other hand, if you want eliminate the need for a shadow, use two lights on either side of the photo light box. Ensure that the level of brightness on the bulbs is the same.
However, there is a chance that there will still be a shadow on the back of the image. If you want to completely get rid of the shadow, place another light on top of the photo light box.
The next thing that you need to consider is the camera settings. Images may also come out a bit dark. To prevent this, set the camera for exposure compensation. This will ensure that the images come out bright.
Color is important for the best quality images. To ensure that the image shows off the right colors, set the camera to white balance setting. It should also be the same with the level of brightens on the light.
