It was a fantastic job for your first time. All I have to say is work on your lighting a little bit, there is just too much glare coming from the left.

Good sharpness on your image!  One way to control the highlights burning out the left side of the coin--on the right side, use a white card just outside the field of view. This will fill the shadows a little and the camera's exposure program won't have to burn out one area to properly expose the right side. |

Thanks.
Yeah, I'm not really sure where that hot light from the left is coming from. I'm working on a little light booth to control lighting and I want to use LEDs on a rheostat.
Since the A520 is tether capable (with the Canon software), would the canon hack open this up on other models?

It's my impression that CHDK does not affect this capability if Canon doesn't originally provide it. I don't believe *anyone* offers current-generation point-and-shoots with tethered shooting capability - you either have to find an older one with reduced megapixel count, or look into dSLR territory. |

Yeah, I was researching trying to make up my mind and found that only a few of the "A" series were tether capable. So, I've set my mind on either the A620 or A640. 7 Megapixel and 10 Megapixel, respectively. Both come with the Canon Remote software. And the swing out LCD is a nice bonus. Either one will serve as the dedicated macro rig quite nicely I think.
I'm not quite ready to give up my Nikon yet to trade up to a dSLR. (But I feel a change coming on!)
Thanks a ton Dave for your help.

The A640 would be the obvious choice, but they're going for ridiculous prices where available. Food for thought - an average dSLR with whatever the "stock" lens is, will immediately duplicate the best you can do with most point-and-shoots. With that said, I think only Canon offers tethering software for free. Nikon and Olympus have it, for a price.
My standard lighting rig uses halogens; I wired a dimmer in, but find I never use it. All that happens when I dim them is, I have to change exposure parameters and still get the same artifacts. Placement is far more important than sheer intensity of light. LED's are on the list of things I want to explore down the road, though.

Like you Dave, I've been a dedicated Nikon(nope, NOT Canon) user for many years. Got a ton of lenses, so a dSLR brand is pre-determined! I will only use tethering on the macro rig anyway so the Canon is a no brainer.
I have an idea for a light tent using some sheer nylon material and some 1/2" pvc tubing. I'll post pics if it works out. The A640 is supported in Win7, which is my newer laptop, but I have a spare Win XP laptop that can work for the A520 if needed.
Frankly I'm rather excited, new ground to explore. I can already see this overflowing into my other pastimes, like homebrewing. Anybody want some CLOSE UP pics of hops?!

Well, when you take the dSLR jump, I'd guess the brand is settled.  No real qualitative difference exists between Nikon and Canon, anyways; Canon is just where I landed years ago and I settled there. As far as OS support, if you're going Canon point-and-shoot it's more about ZoomBrowser rather than the OS. In Win7 it seems to work well for some and has issues for others. Worst case, maybe you do it in XP Mode. A light tent will be a solution to *some* problems, not all. They tend to work well for general illumination, at the cost of accurate representation of luster. |

Hehe, in microsofts infinite wisdom, XP mode is not part of Win7 64-bit Home Premium!
Either way, I've got it covered with either laptop.
The light tent will be an interesting way to experiment with lighting. Many years ago I worked here in Branson in the theaters as a lighting tech, so trying out some gels might provide some direct light with out the glare. We'll see how it goes.

Well, Dave, you were right, the A640 are going for big prices.
So I wound up with a Canon S2 IS. $89 shipped. Tether capable with Win7 !!
Color me giggled!

I am quite pleased to hear that. The S2 IS is one I am experienced with; it is the camera I replaced with my first dSLR. It could be said that I learned coin photography with the S2 IS. Learn its' capabilities, and you will find it quite satisfying. Furthermore, it's a tremendous everyday camera; left on Auto and playing outside, it does sharp images with prefect color.
Couldn't be happier for you.

Yeah, after reading several reviews, I kinda got that idea of it being a good way to ease into digital. I always wanted to try macro but with film it can be very hit or miss and film was expensive to blow on trial and error.
Anyway, thanks a ton for your help and guidance. I'll be posting more with the trial and error of tent lighting!! ;)

My best efforts with it resulted in images of crown-sized coins at 1200-1300 pixels diameter, and minors around 800-900 pixels, to give you an idea what to shoot for.

Was that with an add on lens?
I'm gonna try to get there without using an add on.
This all started as a dedicated Macro coin setup, but after reading about the versatility of this camera, I have a funny feeling this is gonna snowball on me!! ;)
(is it just me or is my Nikon whimpering?)

That's straight out of the camera. I've never used an add-on lens, the reasoning being that it would not only multiply the resolution, but also multiply the optical errors and make it all the harder to get right.
"Versatile" is the best word for Canon's whole Sx IS series. Nice cameras.
