[QUOTE="SuperDave, post: 2668979, member: 1892"]I'll address this end, since Doug said all that's needed on the main subject. Set the iPhone on a solid base, pointed straight down at the coin. Use a monochrome background - black, white, grey - to give its' camera the best chance to get color correct (not that it's bad in your image). You may need to experiment with distance a bit to determine the optimal combination of sharp focus and image size - your image is a bit out of focus although plenty good enough to see what you needed seen here. I wold be hesitant to grade from it, though. Trigger the shot remotely, without touching the phone. There are a few different ways to do this - earbuds with a volume control can be used with an iPhone. This prevents any chance of introducing vibration from your touch. The coin should be presented square to the viewer, with no rotation. This makes visualizing features and spatial relationships easiest. Yours is a bit rotated counterclockwise. Crop the extraneous background away after the shot, right to the edge of the coin. None of that background is necessary, and it interferes with the final image size available to the viewer, especially if you're not reducing the filesize. The image is 783kb as it is; cropped just to the coin it would be down around 500kb or less. Be picky, and hold to a high standard of quality. iPhones are [B]terrific[/B] coin cameras, and there is no reason why you cannot shoot gradable images of all but the smallest coins with one.[/QUOTE]
