Extreme closeup photo
ras...@gmail.com
this is an actual crop from the image, it isn't enlarged or enhanced
by photoshop. this was taken on a new a nikon d300 and 60mm macro
lens. for comparison the inset shows the actual size of the coin held
out to a foot or so away which is about normal viewing distance.

whikle working this way with coins is awkward, not to mention the gear
being so expensive to view a coin this big in "real time" on a big
monitor is a jaw dropping experience. the setup itself is a bit
complicated. you need first of all a tv/monitor with HDMI "high def"
inputs and a camera that can output in hdmi. then you need to have the
coin placed under the lighting rig you normally shoot from with the
camera and monitor tethered via a usb cable. lastly the working areas
have to be close enough to each other that you are able to rotate the
coin while viewing the image on the monitor. you can then take
screenshots of areas of interest. in fact, if you pull the lens back
enough you can take an image of the coin without ever pressing the
shutter!

Very impressive, thanks for sharing.
I have experimented with my camera (Canon S3-IS) on a tripod tethered to the computer
via USB to view the shots in large scale on my monitor rather than the camera's
viewfinder and use the keyboard to trigger the shutter. This gives a lot better
opportunity to see that the lighting and focus are optimum.
I have also been interested in the new "toy" magnifiers that are on the market like
the "EyeClops". It seems that with the quality of digital cameras increasing so
fast, and the prices coming down, a quality consumer digital microscope for coin
collectors and other hobbyists may not be far away.

Maybe I should have checked the 'net again, there are a few out there now. If only
they'd upgrade to a quality lens system, these might become more useful.

200x magnification is pretty good. That is what we used to use when
terminating Fiber Optic connectors to see if there were scratches on the
head of the connector.
Thanks for the info

Good sharp photo. Although my camera has a super macro mode for taking
shots like that I need to rig up some type of steady tripod before I
can get pictures that are not blurry. Or at least get them easily
without a lot of trial and error. For now, I just use the continuous
shooting mode and take 5-10 pictures at a time without 1 or 2 of them
being pretty good.

Anyone ever look at a coin with a powerful microscope? I've wondered
what a PCGS MS-70 coin would look like with enough magnification?
