  1. Wow, some awful nice coins posted recently. The w/a half is superb, Bill!!!

     

    Here's a recent NEWP compliments of Mark Feld:

    This coin was a bear to image. Had it not been in the holder at a slight angle, the color would be impossible to capture. Regardless, I'm still not happy with the result, but it will have to do for now....Mike

  2. I'm still having a tough time with taking images and slabs.

     

    Join the crowd. smile.gif I think that was a pretty good effort and bet the coin is MUCH more impressive if you flash the mirrors.

     

    A few tips (not that I've mastered the art, and there are many coins that simply defy in-slab photography). Hope these helps:

     

    1) Longer lenses help a huge amount.

    2) Keep the light as close to the camera as possible. Moving the light "above" the camera will often allow you to get even closer.

    3) If the coin is in the slab tilted at a small angle, use this to your advantage. When you're taking the photo, try moving the light in a circle around the camera until you find the area that "lights up" the coin the most.

    4) For the most impossible coins, I've found that using extremely diffused lights (using a photographers diffuser or a piece of paper) then just shooting through the slab glare can result in images that can be maniuplated in post processing (to remove the contrast lost) to resemble the coin's color and look.

     

    Hope this helps. Take care...Mike

     

    p.s. here are two more NEWPs from FUN, both compliments of Mark Feld.

  3. The nickel shot was from about a foot and a half.

     

    I had forgotten there were a few coins I had brought home to re-image . After a few minutes experimenting to see what the sweet spot of this lens was, here are a few more quick pics:

    Here's a link to the larger unretouched photos (click "next" for the reverse)

     

    My first day thoughts on this lens (Nikon 200mm f4 AF-D Micro)...

     

    o The sweet spot is about f/11 for coins -- enough depth of field to capture the depth of the coin in focus yet not too small of an aperature to cause significant loss of sharpness through diffraction.

    o It is significantly sharper than the 70-200 w/500D.

    o It seems to be sharper than the 60mm micro.

    o It has better contrast than either lens -- this additional contrast will probably be the single biggest improvement visible in the photos.

     

    Have fun...Mike
