I'm using a Canon SD780IS Settings are natural sunlight,ISO 80,macro,tripod Just can't seem to get the sharpness or color quite right program is HP ImageZone then saved as a paint file to reduce size Any ideas ?

Couple quick thoughts.
First, I'm not sure but it seems like the coin isn't *quite* parallel with the lens - it kinda looks like the right side is a little less-focused than the left.
Second, are you using manual settings or just reading the Automatic settings the camera is using? Try running the ISO up to 200 - that will make for a much faster exposure which is occasionally the culprit with point-and-shoot cameras.
I'm guessing this is a much smaller shot than the camera is actually giving you. If that's the case, you are only a little postprocessing away from some really, really nice stuff. You're already 95% of the way there.

SuperDave, thanks for the quick response and giving me some hope...I was getting frustrated.Yes I was using manual settings so I'll change the ISO and then start looking for some post processing tips. I needed direction...95% of my hair has been pulled out.I'll double check the parallel too, I know to do that from your posts,but maybe I need a more accurate way of setting it up.

I'm interested in these tips too, since I have the same camera. I find my biggest problem lately is lighting. I'm always getting reflection from the camera (which is the red model!). I know I just need to play and experiment more. Thanks

I just read SuperDaves lessons fro beginners and saw one thing that caught my eye..the part about being no closer than 6" from the coin.I've been getting as close as possible...more like 1".

It's working. Your Canon can do it. Don't mess with it. Yes, there's that little band of brightness from the hair down to near the lapel, but it doesn't interfere with eye appeal or the grading-quality of the photograph. Was I right in thinking your images are a lot larger than you're showing here? If so, you can back the camera off a bit in order to possibly bring different lighting into the picture. What you have here is large enough to come up with a reasonable grade; if you shoot for an as-shot image size of 800 pixels (as opposed to the 600 pixels of the image you posted), you might get the camera a fair distance from the coin. You don't need the final image larger than 800 pixels if it's nice enough. If this is the actual size of your images, and you're using the camera on the highest quality setting, then work with what you know works for light and we'll see what incremental steps we can take to improve.

Yes, I believe they started out at 4000 x 3000.I cropped, then reduced to 600 x600 before I saved in paint so I can post here.

If you were only an inch from the coin, then you didn't have much left to crop and those pics were stupid big before you downsized them  You're doing this even better than I thought. Email me a full-sized image, and I'll show you what I mean.

I have the SD790IS, which is the same lens, but only 10 megapixels. I shot this coin hand-held at ISO 200; it's just a matter of practice to get parallel to the coin. Lighting, of course it a bit trickier for BU coins. Good luck!

^^^^ I strongly urge you not to listen to that man, whose God-given skills are ridiculous and he probably shot that with his eyes closed.  For the purpose of our conversation, stick to newer Lincolns. They're very, very difficult to get right because of the combination of luster, color and indifferent relief; I suspect you could duplicate DVCollector's tremendous results today with a similar coin. You've already chosen the hard way, and are getting great results with it. The rest (excepting lustrous silver, another problem entirely) will come easy.

 yeah, it's good to hear my methods have decent results. Listen to SuperDave--his techniques are solid

Newer pennies are a problem for me.But I wasn't able to email a pic to you...didn't see a way to attach it using our PM system...figured if you reply,I'll be able to do it.

SuperDave, I sent the original...it was 4.25 MB..I know that's large and wonder if it went through on a reply ? Also downloaded GIMP...that's going to be a new challenge,but I like the ability to do elliptical cropping.

I got the pic. Forgive me for not replying - your image was one of over 200 I received yesterday alone, and I'm the proverbial one-armed paperhanger these days.  It was so big I had to giggle. I had no idea you were getting such large images from that camera. It's bigger than my dSLR and 100mm Macro lens provides. Amazing results from such a tiny camera; this one just went way up on my list of "bang for the buck" coin cameras. With that said, you're giving up a little focus in return for size, I think. The coin looks nice and sharp once downsized, but the camera's limitations show up in the fullsize image. As I thought, it was a tiny bit out-of-parallel, the left side being in focus while the right was not. You can, I think, double the distance between camera and coin during the process of experimentation. I believe you'll still have images way too large to post here, and the camera will have an easier time of focusing. Machine Doubling. This is silly - a camera the size of a cellphone should not be able to do this.

Not a problem at all, I don't expect instant gratification...after all, you have a life ...but I appreciate the help and will continue to upgrade my camera skills thanks to people like you.Funny about the MD...so I have a 1997 DDO-1 with MD too...I think it's minor enough not to affect the value. I'll back off a little and then work on getting some lights like you've recommended...again, thanks very much
