Here's an idea I've been playing with. Since die varieties such as overdates are best understood from several lighting angles, I have shot this 1875/4 from 9 lighting angles. I then compiled these stills into the animation you see here. This is my first try--there are things to finesse such as lighting angle. This works best shooting with a macro stand; the apparent motion is an optical illusion. Shot with my D810 and 105mm micro @ f10 ISO 160, Mup + EFCS. |

No--just a single Jansjo light at a low angle to bring out the details.

I would love to see this effect with an over buffed reverse DMPL or PL Morgan dollar. What program are you utilizing and how does this work? Edited by CherreePicker

Love it! It's tough (or impossible) to capture the character of many varieties with a single lighting situation.
This is complementary to what I am doing with 3D, except using light instead of viewing angle. It would be very useful to automate the process with a multi-LED ringlight.
What program did you use to make the animated GIF?

I suggest slowing it down a bit (2 sec/change?).
I spent a lot of time thinking "Wait, let me see that again".
I couldn't absorb the details quickly enough.
And coming around again didn't really help.
Possibly viewer control when switching one image to the next.
But I think you are on to something good.

Thanks all...there's a lot of room for fine-tuning.  Setting up a ring light to do this would make this easy as well as more consistent results. Quote:

Btw, here's the same animation but with 2 second intervals. I like 1 sec. best, possibly because I'm already familiar with this overdate  |

This begs to become an animated .gif with about 15 cells, each featuring a slight move of the lighting source in clockwise fashion. Make the shadow circle the coin, sundial-style, and the mispunches will jump out at you.

The shadow does (roughly) circle the coin--but counterclockwise. All good ideas for the next round of shots--although precise lighting angles/increments will be tough to achieve manually.  |

Here's a newer overdate animation. I like this one better--it captures some interesting details, especially on the 0/9. You lose some image quality converting to gif, but I think the information presented makes up for it. Peru 1/2 Dinero 1900/1890  |

I've done this with full-coin shots to show luster or unusual surfaces. I use Photoshop to ensure the registration from image to image is correct, then Imagemagick scripts to build the animated GIF file. Nice, original 1907 Saint in 64.  1889-O VAM 23A. Radial die break from 2nd T in STATES into the d of God.  1903 VAM 1A. Agressively polished dies (both sides).  |

Messydesk--nice work! I especially like the changing luster on the St. Gaudens--it gives it a sense of volume.

You lose some image quality converting to gif, but I think the information presented makes up for it. The reason for losing image quality is that the GIF format only supports 256 different colors. Even on a uniformly colored coin, if there is color noise in the picture, that noise will mess with the 256-color palette selection. For close-ups of varieties, I almost always convert to grayscale, as color information is at best useless when looking at pictures of varieties. Since grayscale only gives you 256 shades of gray, no further color information is lost when converting to an animated GIF. |

I suggest slowing it down a bit (2 sec/change?) with the rate of your most recent deceleration of the speed DV. And as one additional option to consider offering to the viewer, would it be possible to allow one to manually browse through a predetermined series of distinct shots by conveniently tapping the 'tab' key, for example? In this way a user could stop and study just one particular lighting angle, for instance, for any desired amount of time w/o being rushed on to the next slide etc.... Folks measuring dimensions and angles would find this type of feature invaluable and time-saving in the long run. mdpmedia |
