<p>[QUOTE="SuperDave, post: 2287037, member: 1892"]Here's the basics:</p><p><br /></p><p>1) Coin and camera lens plane perfectly parallel and solidly stable. Macro photography involves very shallow depth of field, and if the coin is tilted with reference to the camera you will likely not get the whole surface in focus. Further, angled images subtly distort spatial relationships, and can deceive the viewer on date and feature positioning when you're trying to attribute.</p><p><br /></p><p>This is most easily accomplished with the coin on a flat surface and the camera pointed straight down at it, employing a tripod. In a pinch you can use the corner of a table - it will fit between two legs of the tripod and give you enough overlap to safely place the coin. Here's how you determine alignment: Place a small mirror on the flat surface where the coin will sit. Using the camera's viewfinder, arrange the camera so you can see the lens reflected/viewed exactly in the center of the viewfinder. When the lens reflects exactly in the center, you are perfectly parallel to the shooting surface.</p><p><br /></p><p>2) Delayed shutter. Do not trigger the shot with your finger on the button; you can introduce vibrations which will mess up the pic.

Extraneous lighting hurts contrast, as does light reflected into the lens which does not come from the coin. You don't have to be completely paranoid, but for instance the silver surface (if it's that color) of a computer next to your imaging rig can reflect enough light into the lens to hurt the shot.

"Color Temperature" is the "shade" of light - you'll see it described as "Warm White," "Cool White," "Daylight" etc. - and it's measured using the same Kelvin scale as used in astronomy to describe the color of stars.

Virtually every camera of the last ten years can correct for color temperature, and your Nikon has the ability to do Custom White Balance, meaning you can effectively tell the camera what you want it to call "white" and work from there.
