Help with Pics and grading.

I am new to getting quality pics from my coins. I have asked about grading and trying to get the correct tone.
I read about white balance and artifical lighting. Now, is sunlight the better source?
I have 2 sets of pics on one coin. The 1st is light from the lightbulb and a light from my tripod. The 2nd set is from the sunlight on Monday. To me the sunlight is showing the coin in its true form.
I believe I grading the coin at AU-55, but some people said XF-40. That was with the artificial light.

Let me know if I am on the rt track.

Thx

Those look better than your first ones...

...and MUCH better than mine.

I just can't get motivated to take better pictures.

Good job.

You are certainly getting there. From what I see you still have a bit too much reflection going on. Try to diffuse the light from your light bulbs and see if you can duplicate the sunlight pictures. This can be done simply by placing a tissue or something in front of the light. Remember, the light will get hot.

You could also try having the coin next to a white wall and having a light shine into the wall, thus only receiving the "reflection" of the light from the wall and no direct pointing. Also, how close are you to the coin and what type of camera.

As a note, your second set is very nice.

Thats awesome! Thx for the comments zero :)

Its all about the learning curve.

tights24, too much light? I guess you mean on the 1st set from artifical light, correct? Since sunlight is directly on the coin in the 2nd set, is that too much reflection?
Good Idea on the diffuser. I will give that a try.

I was on the macro function (the 1st set was on the super macro), and I would guess 5". I didn't measure it. The camera is a Canon S51S.

Again, thx for the advise.

Keep in mind, you're working with particularly difficult subjects in Peace dollars. Even well-struck, they don't offer really sharp contrast between fields and devices. So, although I'm not suggesting that you lower your expectations, be aware that a circulated Peace dollar isn't the ideal coin to be perfecting your photography skills with, as it's not going to give you those "eye-popping" results available with designs that have better relief.

There's a reason why I use copper for most of my examples in this forum.

Have you looked around at some of the threads here regarding camera placement and use? I think your Peace dollars might be best-served by one lamp, at a bit of an angle, around 10:00 to the coin, like so:

Lighting,-Pics-And-Grading

You have a very good basic camera, and you should be able to expect similar results to this, once you get it dialed-in. Try backing the camera off a little bit - shoot for a final size of about 800 pixels instead of the 1000 you're getting - and that might allow the camera to get a nicer focus and give you more room to play with lighting.

I went looking, and found an example of what another forum member has achieved with the exact same camera as yours:

Lighting,-Pics-And-Grading

It's a Mint State coin, and admittedly a better candidate for photography than a circulated one, but it's a goal for you.

Note he's using one light, at about 1:00. It brings out hair detail better than my shot, I think.
