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!

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
