Sounds like your AF experiences are more like mine. I find AF completely useless on anything smaller than a Dollar. When focusing on smaller...
I'm very fond of the cheap Chinese Z-stages for adjusting focus at higher magnifications. Nice to move the coin rather than the whole camera and...
To capture a mintmark with a bit of the date on a Cent, you need 10:1 magnification. Here's an example: [IMG] The extension required is easy to...
You can get what's called an "18% Gray Card" that you can use as a background for coin shots. Use the card for setting the White Balance, then...
No, that image is fairly well-balanced, except for the few lost shadows around IGWT, and a splash of mostly R highlights across much of image....
As long as there is sufficient dynamic range in the image, then the overall brightness is easy to adjust. The latest image does have more lost...
Here are the areas that are over-exposed in most recent photo: [IMG] And here are the areas from the previous photo: [IMG] The most recent one...
Once you have eliminated the over-exposure, and have the contrast set so there are no lost shadows, you will have what I call "good raw material"...
Maybe a bit dark, but a much better image. It is actually still a bit over-exposed, but within reason. You can improve by using Style settings...
Go into the Shooting Menu, hit Save/Edit, and the Style menu will be shown. You might want to pick Neutral, and then go to the Adjust Settings menu.
Better, but still a little over-exposed. Try making the EV -1/3. Not 1/3 less, but actually -1/3. What Style settings are you using in the...
Much better. You might want to move the light at 6:00 farther from the coin, or maybe add some diffusion to it. Overall contrast is a little low,...
Looks like your lights are at 3:00 and 9:00. Tilt won't help you much in this case. I recommend moving the lights to 10:30 and 1:30, and then...
I have occasionally used animated gif images to display luster or color variations due to change in angle. A series of stills can be used to...

Check out Brandon's thread he linked to on first page. He shows the effect of low, medium, high angle lighting.
Mark's book is excellent, and every coin photographer should buy a copy. It will give you a starting point for most all styles of coin...
tpsadler...the totorial post by Brandon (brg5658) is excellent and should get you started. The post explains two dimensions of coin lighting: 1)...
Best for you to start another thread to talk specifically about lighting. Don't want to hijack this thread, unless the OP wants to go down this...
Most of the work in coin imaging is getting the lighting right. Is your 105mm lens a new Micro-Nikkor AFS type? If so, lighting is going to be...
