Ok, I've shot some pics in Av. This is easier, no constant WB adjustment. I was also worried since no shutter speed is shown in the slot. But now I notice the picked shutter speed flashes when you take the picture.

Another convert! I personally don't really care what shutter speed the camera chooses. The Canon EFSC eliminates all shaking, and as long as the speed is "reasonable", ie shorter than a second or so, there is no impact on my workflow. It's not like my coin is crawling around or cleaning itself.

So I received a Nikon M5 microscope objective and the RMS adapter a few weeks ago. So here are a few pics. First a 75mm lens with the shot only cropped square. Then 2 shots with a 50mm lens, and finally the same area taken with the Nikon M5. 75mm  Now 50mm   Now Nikon M5   I think the M5, unstacked, lacks the clarity of the 50mm lens. Obviously, the M5 produces a more magnified image. So its on to experimenting with stacking to make this sharper. |

Wizzy...all those shots look excellent. It looks like you have a very good copy of the 50mm lens. Sharp and detailed, and you nailed the focus. The in-focus areas of the M5 are nice and sharp but overall you are correct, it needs stacking. A 3-stack is probably sufficient but likely 4 or 5 would be better. When stacking manually, you have the advantage of using Live View to make sure you are critically-focused on the important features you want to be sharp in the final image. This way you can minimize the number of images required. You can also visually determine the DOF during this process and adjust accordingly.
One piece of advice...The front chrome piece on the M5 is just a trim ring, and purely cosmetic. If you remove it, you can get a bit higher angle with your lighting...Ray

I know there are some blown out spots on the 1st picture, but I'm kind of lazy with post production stuff. Is there a big advantage to using more than 2 lights to limit overblown areas prior to taking the shot?

Adding diffusion on the 2 lights can reduce the over-exposed areas by spreading the light out more. Is usually better than adding a 3rd light IMO but there are times when a 3rd light (or reflector) is necessary if you don't want to do PP.
CombineZP is the best free stacking software I know of.

My first stack. A shot of the Full head on a 1917 SLQ. Whole obverse  Full head stack using CombineZP  I used all six methods to stack and picked the best one. Its a little intimidating to use. I'll have to compare this shot to the 50mm cropped. It's much easier to light the coin with the 50 mm lens. |

That coin makes me weak. What an amazing SLQ. And *that's* the beauty of this kind of photography - you can present a coin like this in all its' glory, as it deserves. Images like these drag new collectors into the hobby.  |

Wrong forum. Anyone else ever notice blue specks on Standing Liberty quarters. I have a few that have them. In these shots they are in front of liberty's forehead, front of the cap, and at the back of the jaw line. |

I just got it, Dave. Its graded MS-63. Heritages photos didn't do it justice its a real undergrade.

Did I do the stack wrong? I took multiple shots moving the entire camera body and lens. In the other thread austrowiki said only the lens moves. Which is the correct method?
