I do snapshots not careful commercial and professional photos. Prefer to show things as they are. Use natural diffused sunlight so have to digitally correct sometimes only for blue. Use moderate price Canon G6. Make certain not too close to object with lens and smallest aperature thus good depth of focus. 7 meg. pixel adequate for tight cropping so depth of field retained. I like images that actually show reflections and shadows like the real world thus are truly representative. I submit this because a watch recently bought has a an odd silvery reflective grey and white checkerboard dial difficult to photograph, but by simply using natural sunlight off the white room ceiling at an angle it shows up well. No need for fancy equipment, special lighting and optics. Added a couple of same movement photos as example for depth of focus. Watchmaker does nice image with fine equipment and closeup lens attachment. Note some depth of field loss. The black background is from moderate close focusing and cropping, but still sharp all over, and has better color fidelity because of natural sunlight. Black is best for color fidelity. I have never seen a
green gold watch case image like this that actually shows the green.
