Was perusing the forum and noticed threads regarding stacking for close up shots which got me thinking. My wife says this is dangerous. Anyhow would stacking be applicable say to attempting to get a nice shot of an over buffed reverse. Now I know this shot is horrific, out of focus, bad lighting etc. and only post it to bring up this point. Due to the reflective nature this is an 1883-O VAM 1C1 DMPL which is absolutely gorgeous in hand but an absolute bear to take pics of. Trying to get the overbuffed areas to "pop" I have tried shooting at angles etc. and wondered if stacking would be applicable in a situation such as this.  |

Stacking is one option to get this image fully in focus. Stacking allows you to tilt the coin and then focus on each focal plane along the tilt, and use software to stitch together the in-focus areas.
Another option is to use a tilt adapter. The tilt of the coin can be compensated by a complementary tilt of the camera or lens. My preference is tilting the camera as it gives you tilt with minimal movement of the image circle.

Ray do you have alink to a "tilt adapter" to see what it looks like. Shot of the reverse which does not show the over buffed areas with no camera angling.  |

Caution...that adapter tilts at 45-deg on camera axis. Not adjustable. So you need to tilt the coin that way as well. Can make for interesting lighting but it does allow variable tilt. My copy of the adapter is also misaligned for tilt angle indicator. Would be nice if it could be adjusted for tilt plane but it seems like it's machined that way...

Thanks looks interesting. Seems like it might be easier to play with angling the coin itself; including greater range of motion. Gonna have to think about this one a bit.

Wouldn't your "pocket mirror" solution for alignment work for this technique as well? |

The process is to angle the coin and the camera by the same amount. This ensures the whole coin is in focus.
I'm not sure how to use the mirror technique combined with tilt. Gotta think about that.
BTW, since the lens inverts the image, the angle of the coin and the tilt adapter need to be opposites. Close to close, far to far.
An interesting thing about this technique is that it does NOT fully compensate for the visual distortion from the tilt. Seems like it should but it doesn't. So the coin will appear oval shaped for big tilt angles even though it will all be in focus.

Wonder if forcing it square in post would be effective. |
