That is a stunningly gorgeous coin and photo! I think your test of repeatability was a success. I notice you've been shooting at f/5.6. I've been mostly shooting at f/8. Do you think that's still a decent "sweet spot" for the 75ARD1? Keep'em coming. This has got to be one of the best rolls of wheaties for toning I have ever seen!

Thanks Brandon. I still have 12 more toners to image and post!
I prefer to keep my effective aperture below f12 or so to avoid strong diffraction effects. For full frame Cent photos, the magnification is around 0.84 to fill my Nikon sensor. Since the effective aperture is Feff = Finf (1 + M), this gives an Feff=10.3 for Cents at f5.6. For Dollars, you can stop down to f8 since the mag is lower (M=0.42). This gives Feff=11.4.

Perfect, that was the exact explanation I was hoping for. I always forget that little formula. I look forward to seeing the next 12 toners!

The filled date "9" and "5" are interesting on that one!

did you make the smile directors (covering light source) or are the available commercially?

Had to make them. Nothing like this is available commercially! Paper, scissors, tape...Ray

The pink on the reverse of #8 is actually as vibrant as on #11 and #12, but the Canon seems to be bringing them out more accurately. I'm doing essentially the same post processing, using the same tool on both camera outputs, but the Canon is just doing a better job with color accuracy. Love this new T2i! But now I have to go back and re-shoot #1-#8...Ray

First off, sorry for bringing this thread back from the dead, (as it were), BUT, I felt that it belonged back in the 'main stream'. It helps explain A lot about 'smile directors' and I have to say that prior to reading this thread, I had No Idea what they were. I hope this is ok. Charlie. And Ray, Beautiful work Sir!  |

No problem Dar, sometimes old threads have lots of good info. The original Smile Directors worked great, but since then I and several others have moved to fixed systems that do exactly the same thing but are easier to make repeatable. CaptainFwiffo was first to move away from applying the Directors onto the lights themselves, and did the "Lego" version of the Smilies. I took this one step further and moved them to attach directly to the filter threads on the lens, and the 'Cap took it even further with 3D printing of a modular Smilie system. He shipped me such a system weeks ago but work has kept me so busy I have not yet evaluated them. I plan to do a full evaluation on some toned Cents I'm supposed to receive for imaging, and I think the 3D printed system will get a full workout on them. You might PM the 'Cap for more info. I think they are partially documented in another thread as well.

Comparing the "old" smile directors pictured in this thread, and the "new" smile directors a la captainFwiffo. It looks like they work differently. The old ones blocked out a smile like a smile shaped solar eclipse. The new ones let light through like a smile shaped spot beam. Which do you think is more effective? For the old or the new directors where are you aiming the light(or block out)? just inside the rim or just outside the rim of the coin?

I believe they work essentially the same. If you look at the first post in this thread, you'll see two arc-shaped strips of light. These are due to the diffused gap of the "smile" reflecting off the mirror. The 'Caps system does the same thing but is not directly attached to the light head.
