<p>[QUOTE=&quot;Midas, post: 95862, member: 2761&quot;]Not so...today&#039;s laser scanners scan at a <u>multiple</u> angles to collect x,y, and z data (which <u>is</u> 3D).&nbsp; You see this in a number of industries including everything from the military to dental digitized scanning.&nbsp; That is why I mentioned x,y, and z data points (3 points), not just x and y.&nbsp; Laser scanning can collect data down to as small as 10 microns.&nbsp; That sure is better than how coins are graded with a 5X magnifier.&nbsp; Remember...the key is what is the <u>given</u>?&nbsp; My suggestion is to take 10 coins of a given year and mint mark from <u>each</u> of the top TPG&#039;s and make a collective database of what an average is of a given coin from a given year and from a given technical grade.&nbsp; Of course 10 microns is way too small, but you can always adjust how many datapoints you wish to measure.</p><p><br /></p><p>Our eyes can see items very well.&nbsp; The problem is in <u>processing</u> and <u>communicating</u> color...hence the dot experiment I posted.&nbsp; Our eyes see color differantly under the sun than in your kitchen.&nbsp; The given item&#039;s color didn&#039;t change, but the lighting and adjacent colors did!&nbsp; For instance, you could NEVER take a picture of your car and then head to your body shop to buy paint that matches the &quot;true&quot; color of your car.&nbsp; That is why they use color measuring instrumentation that goes directly on the car to measure the color ACCURATELY.&nbsp; The same goes for places like Home Depot.&nbsp; Pick a color in their store and people wonder why the same color looks differant in their living room.&nbsp; Why? the lighting is differant.</p><p><br /></p><p>Bottom line, there is NOT one industry that use photography to measure and quantify color.&nbsp; Is the lighting the same?&nbsp; Is the distance of the light the same?&nbsp; Is the intensity of the light source the same?&nbsp; Are the adjacent colors next to the subject the same?&nbsp; Is the angle of the light the same?&nbsp; The answers to these questions are all NO and hence the reason why photography is great for taking and showing pictures, but never a true exact representation of what color is it.</p><p><br /></p><p>Don&#039;t believe me?&nbsp; Take your favorite coin and take a picture with the same camera outside and then take the same picture of the coin inside.&nbsp; Same coin, differant color results.</p><p><br /></p><p>BTW...here is what x,y, and z data looks like.&nbsp; Imagine 50,000 plus data points per coin.&nbsp; It can happen...the question is would the TPG&#039;s want it to happen.</p><p><br /></p><p>Speedy...the technology wasn&#039;t there back then as it is today.&nbsp; Laser and digital scanners weren&#039;t even around 10 years ago.&nbsp; Think about how much technology has entered the market place over the last 15 years alone.&nbsp; As for your conspiracy theory and being able to adjust data, I guess you don&#039;t trust a computer to add and subtract.&nbsp; Let&#039;s have a race and see who is more accurate.&nbsp; My excel spreadsheet column with 500 figures against your pencil and paper addition.&nbsp; Ready, set, go!...I am done.</p><p><br /></p><p>Consistency, consistency...how do we achieve that?&nbsp; Here&#039;s a start.</p><p><br /></p><p>&quot;It&#039;s common sense to take an idea and try it.&nbsp; If it fails, admit it and move on to the next...but more importantly, try something.&quot; - F.D.R.[/QUOTE]</p><p><br /></p>
