| So then we could crop the final photo as seen below. Cropping a digital photo is easy with software. You can crop a slide by removing the transparency film from the slide mount and masking around the image with thin, metalic tape called "slide masking tape". Then put the slide in a new slide mount. Plastic slide mounts and the tape are available from good photography stores. |

| You must be careful that the lights are illuminating the artwork but NOT the photographer or the camera.. Also, turn off all the room lights and close the curtains... make it as dark in the room as you can, or you might get something like this: |

| Can you see my arms and ball cap in the picture above? You must light the art, and nothing else that will reflect in the glass. If you are using a zoom lens, it is better to use the more telephoto setting so that the photographer will be farther away from the art. If you are using a more wide-angle zoom setting, the photographer will be closer to the art and thus more likely to be lit up by the light spilling from the lamps. Another way to help this problem is to get a piece of black mat board between the camera and the art... and cut a hole to stick the lens through. |
| Great. But that's not all there is to it. We must discuss a few more things... |
EXPOSURE... if you are using a digital camera, you can easily look at the images quickly and determine if the images are too light or too dark. If you are using a 35mm camera and you are shooting negatives or slides, you must get the exposure correct. Particularly if you are shooting slide film, the exposure must be within one half stop. Negative film is more forgiving. When you take a light reading with your camera, the camera doesn't know if the painting is light or dark. It is assuming that the subject matter is middle grey. It tries to average everything out to be middle grey whether the piece is mostly white or mostly black. In photography stores, you can purchase what is called a "grey-card". No kidding. It's a piece of grey cardboard which is the exact shade of grey that your camera meter is looking for. You can hold it in front of the artwork and take a light reading from the card. Set the camera on "manual" so that when you take the card away, the setting will remain the same. If you are on "automatic", the camera will re-adjust. Here is a picture of a grey-card: |
