I also wanted to see how well I could take an attribution shot. These were done with either two 14mm extensions and a 7mm extension. OR one 14mm extension and two 7mm extensions. (I can't remember... I had written down everything except that, I guess  ).  Quote:
That obverse is ridiculously good. The reverse proves how difficult Morgan reverses are even when you're very good at photography - and it's time for you to believe yourself very good at photography. So it's time to concentrate on tweaking your work with reverses on Morgans. The lighting requirement is subtly different. Thanks Dave! I will have to keep playing around with lighting, and diffusion for the reverse. Quote:
Saved from the Gimp at 80% Quality, an 800px coin loses no apparent quality while being around 200kb in size, and anyone on a smartphone or wifi tablet will thank you for it. Noted. I usually save them at 90%. From now on I will also start downsizing. Edited by Canadian-Banknotes

Throw every extension you've got onto it, and see if you can image the result. Let's see what that lens is capable of.  |

You're going to find out what depth of field is all about.  |

Oh yeah, that's what we're looking for! I had fun looking over every inch of the obverse shot, and found no weaknesses. Good job!

Time to download and learn stacking software. Ray's better qualified to recommend the best one than I am. |

I think I'm ready.
I just need to wait for the M42-RMS adapter to arrive now.

The M5 is a nice objective. Its NA of 0.1 (equivalent to around f4) will give you a reasonable depth of field so that stacking can be done fairly easily. For most coin work, you can get away with 2-5 images, depending on how flat the coin is and how much topography you are capturing. Basically, the method is to start at the highest point you can get into focus, then move down a little until the next lower features are in focus, and continue on until the lowest features are in focus, and snap a shot at each point. For software, I have two recommendations.. If you want to start with freeware to get some stacking experience, go to http://www.hadleyweb.pwp.blueyonder...allation.htm and download CombineZP (CZP). It requires a bit more work to use than the pay programs, and it tends to oversharpen the output, but does an excellent job. Supposedly you can adjust the sharpening level but I never figured out how. If you can figure that out, it might be the only program you'd ever need. What I've been using for the last few months is Helicon Focus. All you need for normal stacking functions is their "Lite" version, which is a $30 per year license. It is far more automated, and the output is easier to adjust than CZP. You can view the info here: http://www.heliconsoft.com/helicons...licon-focus/I'm sort of a heretic over on the Photomacrography page, since most everyone there uses Zerene Stacker. I would have used Zerene (also fee-based) but there are advanced features of Helicon that Zerene doesn't have yet, and I've been very happy with the output images Helicon has given me, so I'm recommending it.

Yikes...Im still learning how to take ONE picture of a coin and your already on to stacked photography Canadian-Banknotes, that's great!! I've picked up some great tips here on the utility settings that I didn't even know existed...thanks guys Quote:
We've created another one, Ray. Yes you have! I wonder how many have gone to this setup that me and Canadian-Banknotes have? Canadian-Banknotes...now that you have played a bit with it, how would you rate it? |

In addition to those posting publicly here (you guys aren't the only ones), there are a couple I've worked with exclusively off-forum who preferred to keep their work private and only present the finished result in public. I'd be surprised if fewer than a dozen have gone down this road based on what they've seen here. |

Dave, I am going to try and add as many extensions as I can, to get the best attribution shot possible. Stay Tuned. Quote:

Just a small update: You won't be disappointed with the attribution shots.  |
