THE *COLLECTOR-DEALER* INTERACTION Continued.....

Before we, analyze the above problematic, fear driven, subject-matter I propose the following:   Every Picture tells a story and as a picture so does the coin picture. Who loves pictures the most? The Artist's Collection do! And you can't have fun without a bit of wry humor and less boring facts. You are allowed to be witty by universal law: free will.The subject of the coin dealer strikes fear deep into the center of the collector.At least it does in this collector. There are as many re

THE *COLLECTOR-DEALER* INTERACTION

As per your request: Here is the dealer's coin image. Sometimes the file sized slab image is a bit too small to adequately judge its relative reliability. To see old comments for this Journal entry, click here. New comments can be added below.

THE *COLLECTOR-DEALER* INTERACTION

Coins are purchased from a variety of sources: *Dedicated Auction (Brick & Mortar) Houses *Online non-dealer Auction Websites *Dealer Websites *Dealer Auctions and website Auctions *Direct Dealer Interaction or Dealer afar transactions *Commercial Merchandise Auction Website *Live Yearly Coin Exhibitions: City/State Shows *Coin Club Shows *And Many More What they have in common is the usage of coin imagery. Back to the issue: the coin image is the vehicle we rely on to tell the

APO Lenses for Coin Imaging

Regular camera lenses produce chromatic aberration: Red, Yellow Blue do not focus equally on the CCD sensor plane.Apochromatic lenses, like BRG might use, focus the many varied color rays oflight together on the CCD sensor plane. Regular lenses do not and therefore produce color image distortion.It would then seem beneficial for accurate coin color rendition to use an APOlens.This would include types of copy camera lenses as well as film enlarginglenses and specialized apochromats made for came

There are some very talented Photographers on The Collector's Society.

Thank you so much for your high resolution images. I will have to try your approaches. I tried an old 35MM film, manual focus 55mm Micro-Nikkor on my digital Nikon and below are the results. It appears to have an edge over the AF 105 MM Nikkor. You can be the judge. It's a dime. I had to move the tripod to about 5" from the coin. To see old comments for this Journal entry, click here.

Coin Imaging: Serious and Talented Collectors Post their Creative Coin Images.

I am very pleased that, by accident, I was able stimulate this most encouraging muti-talented display and demonstration of the seriousness of the Collector's Society members.I hope it continues, so we all may expand our abilities and perception.Here's to all the great collectors....Many Thanks!To see old comments for this Journal entry, click here.

BRG: Your Images are Perfection:* CONGRATULATIONS*. Great Equipment Setup

I have a medium format Rollei HY6 with Sinar 65 eSprit 31.6MP back; I also have the Rollei rail bellows and the 120MM Zeiss Makro lens. Curiously enough, using them for coins never crossed my mind because my Nikon is comparable at 32MP and much lighter in weight and easier to use. Plus, one needs a dedicated space for fixed apparatus placement.   The black matte background is a nice touch to make the coins stand out. However, a question I should pose to you is:   Is this type of imaging our

THE IMAGING SETUP:5; The Light Source.

Surfaces and dimensionality elucidate the coin for honest coin photos. The empirical elucidation of a coin depends on the extent of 3-dimensional and and 2-dimensional depiction combined through the use of two light sources. Two sources of illumination combine to bring 3-D sculptural depth with 2-D surface depiction. Thus one has the means to accurately depict a coins reality without resorting slight of illusory, visual computer trickery. Positioning the upper and lower light sources front

Coin Imaging: FYI ONLY!

These journal entries were thought to be private. When I unchecked the box: publish to Forum they were published anyway. When I saw my entries on the left column of my page I was disconcerted. Then I decided that there may be someone who would benefit from the technical information. Since I do not participate on chat boards you can take it or leave it. If you feel it is a boring rant I suggest you do not read further entries. It's your choice. Here is the photo of the coin to which I refe

The Imaging Setup 4: The Camera & Lens.

Does your camera have a large enough CCD sensor to match the coin diameter? The camera for the imaging of coins should have a CCD sensor size comparable to the largest diameter coin you wish to reproduce. This will then allow the clicked-on magnification of the coin's surface detail and luster to be closely scrutinized for comparison of graded coin levels. Years ago the 35MM film format provided enough detail to be closely maintained to hundreds of times the magnification factor in movie th

COIN IMAGING: Theory and reality. A beginning.

Good and Bad intentions: Collectors versus Dealers versus graders.   Who's looking for what qualities and quantities: Personal agendas?What should the nature of coin imaging entail?What are the imaging motives of the coin collector?What are the imaging motives of the coin dealer?What is the fundamental importance of a coin's image?What is going on in today's coin imaging environment?Are the Grading companies accurately archiving each coins real condition? Cultural Posterity?

THE COIN IMAGE TRAP: Ensnared!!

Here's the story of how I was sabotaged by a dealer's auction coin image trap. I recently purchased, on line, an 25c Seated liberty in the ever appealing PR66 grade. This coin was the most alluring entity imaginable: Picture a Florescent red-gold Seated Liberty on a yellow-green pasture with the golden red sunrise rising above the stars in heaven. Breathtaking in its stunning vision. I was the high bidder. When I received it I was dumb-founded by a dingy gray surfaced phantom of what had bee

COIN IMAGING: The good the bad and REALITY

Oh, that's a nice coin! Really. It's pretty and has such beautiful colors!   Errr... under what source of illumination??? And, under what source of computer image software???What's the bottom-line in coin imaging? >Reality, authenticity, actual condition, luster, surfaces, devices: but really only one: OBJECTIVE TRUTH! No enhancement; no twiddling with color, minimal sharpening. No screwing around!Most of the time the defects are more attractive and interesting than apretty made-up face wit

The imaging setup continued:3

The last component I entered was a sturdy tripod; and then, an equivalent height adjustable table-topped tripod placed in front of the camera tripod; the center of the lens plane should be level with the table top surface and the table top horizontal in parallel with the focal plane of the camera.m All of these elements should be checked with a bubble level on 3 planes. The next component is a suitable shadow box and coin holder. The shadow box prevents ambient room illumination from casting

Re-photograghing distractingly, unattractive coin dealer pictures.

I have begun the labor intensive process of reversing the truly, ugly dealer's coin photos in my collection beginning with my Morgan Dollar set. I have made early mistakes that have required creation of several non moveable elements: a coin holder shadow box; a goose neck, fiber-optic, microscope slide illumination system with fan cooling; a heavy aluminum tripod, etc.To be continued....
