Digital Pics
Jetmaven,
It's all in the lighting. Notice in Scott's pics that where the flash bounced back into the camera the reflection of the surrounding Metal Coat is silver. The flash is a very white light. His overall ambient light is probably incandescent. Fluorescent bulbs come in cool white, daylight, soft white, and etc. Cool white fluorescents usually show up as a greenish light. The remainder of the fluorescents that I listed will show up as amber. The pros will use a very white light in conjunction with silver or white backed reflectors. The auxilary flash units used to spread the flash out to a larger area are also reflected by silver or white reflectors. The walls in a photo studio are also colored to give off a certain color of reflection. If you want it to show up as silver then move the model to an all white room and use the whitest light that you can find easily. (Halogen) This should help.
I'm not a pro but an amature photographer. The real pros could probably add more to this....Kevin
PS---Scott, your airplane is becoming a work of art!!! I can't wait to see it in person. Kevin
