You have got to learn to take bigger pics. BTW, you take bigger pics and shrink the pic to fit on the net (usually). If you take little pics, they will always be blurry when you enlarge them. Anyway, I am still at a solid 65 or maybe a little better.
How big do you need them? I have my camera 5" away from the coin with 3x zoom which is the most my camera can do. If I get any closer, the camera blocks the light so If you want a really big picture of it with a shadow over it, I can do that, but otherwise, I don't see anything else I can do.
Well the pictures are small, they need to be a little bigger and show more detail Your pics make it so the coin is like a 70, I don't see any flaws on your coin, and that is not the case. You need to find the right balance between the color of the coin, the details of the coin, and the light. You'll get there with more practice. A word of encouragement, you are a lot better at taking photos, than I was when I kept trying and experimenting! Now I don't use any zoom, at all, I get maybe about 1 foot or so away, and take my picture, then I crop it, then crop it round so I just get the coin, and I combine the reverse and obverse using photoscape. I have one light, bendy neck halogen lamp, and another lamp that I put over the coin. Take advantage of lamps with a bendy neck, I suggest getting two of them, and mess around with em' a little bit. Just keep trying you'll get it!
Your pictures are good, but they are still small, to small to see anything. I wish I had a picture of a wheat cent, but I don't. Try to set your camera to the max setting of megapixels (mine is a 6 MP camera, and that is what I shoot with 6 MP) See how big this picture is? Try and get your wheat near the size of this, so we can see the details up close on the coin.
I think the problem was that I was putting it in my ct album which resized it and then I used the link. How's this?
