Over time I've learned more and more about coin imaging. Now I'm trying to put it all together. Please tell me what you think of the images, NOT the coin.   And if you REALLY want to say something about the coin, go ahead. It's an NGC AU-53. Edited by kanga 09/09/2015 1:24 pm

kanga hello first impressions. I am still learning as well. I will say I have improved but still have a ways to go. ok first impression. first image at the top of your coin it is just slightly and I mean slightly blurry to me. the second image is bang on perfect. did you change any thing or refocus. great job on your photos.

Quote: did you change any thing or refocus. great job on your photos. CHANGES: -- I had to turn the coin over -- I'm using manual focus so "yes" I refocused on each side That's about it for changes.

kanga great photos. what I am learning for myself is that for different metals. I have to use different lens. see I don't know enough about the camera like the more experience shoots here. so I did trail and error with lens. I have found that for low lustre and dark metal coins enlargers lens totally excellent. I use for silver and nickel Minolta 100mm f4 bellows lens. the lens makes it easy to light the coin and very easy to photo. plus the coin look just like when its in my hand. for that type of metal. here is and image taken with the canon t1i and the Minolta lens. 2 janjo lamps

Here's a Half Dime that I got right. I imaged 5 Half Dimes but this is the only one I got in focus. They are so small that I'm having lots of trouble imaging them well. But I not have some suggestions that should help correct that.

Nice pics in this thread.
What type of lighting do you use for these images? -- it seems like there's good contrast, but no burned-out highlights. No matter how diffuse the light I use (except for the macro ringlight), it seems like I have to way underexpose most of the coin to keep the brightest spots from burning out.

kanga great photos you are very good at this. I will set up my camera again. I will take a photo of a old Canadian dime. your shots are great. I find we some times judge ourselves to hard. you are very good at this. there is a few here that are over top. they are great helpers where my skills lack is the camera. I don't like changing the camera but I will from time to time. those Half Dimes are excellent

hello kanga took a couple of shots just now. I crossed the border this morning got my hands on a American penny. I took one of a older Canadian nickel. I like the Minolta bellows lens because the smaller. the coin the more I can extend the bellows making it easier to focus. see where it is a bellows lens. I am able to keep the light along way from the coin. with the right diffusion. the coin lights evenly.

kanga if you don't mind my asking. what do you use to take your photos. camera lens and mount. just wondering like to know. when I crossed the border this morning. I met with a very old gentlemen. I purchased a lens from him. he lives In the state of Maine. he wanted to see some coin photos. so I showed him some links here. he was totally amazed at the photos here. he said if you get that lens to work. he said I believe you will be very happy with the results. it is one beautiful piece of glass. I am amazed at the resolution even looking through it with ones eye. he laughed he said strap that on a camera. if you can find a connector or adapter. I believe you will be very happy.i believe so have a great one

Very nice kanga. I too would be interested in your setup. The only thing I see is that both your images could be rotated a bit.

Hah! I am not the only one. Rotated coins are a pet peeve of mine.
Kanga, your shots are looking pretty decent. You have some focus issues on both obverses, but the reverses look better. How are you doing your critical focusing? And what are your aperture settings? Your contrast, highlights, shadows, and overall lighting look good. How much post-processing are you doing? Might be good to show what your shot looks like coming out of camera, camera settings, and what you do for post-processing. But first: figure out your focus issues; then rotate the coins so they are properly framed! Then show us your process if you don't mind, it will be good teaching others how to get the results you're getting.
