A PhotoChallenge for our better forum shutter-bugs.

Apparently our membership is obsessed with AT and NT coin-judging as demonstrated by the continual posting of and responding to threads which beg us to vote either AT or NT. Some of the threads are actually able to suck long absent members from the ranks of "lurker" back into the "regular poster" ranks. In the interest of further educating ourselves with the fine points of digital online pictures I thought it might be fun to try a new little exercise. Here's how it goes.

Take a picture of a coin which you feel relatively certain is one displaying original tone, post the best quality picture of the coin that you can and then post the same picture juiced so that it looks AT. That may seem an easy task, but the trick as I see it will be to get a "played with picture" that doesn't look played with, a picture that just looks like the coin's tone isn't real. I'm sure someone can come up with a really, really goo pair of pictures.

Are you up to the challenge??

Here is my attempt. The coin is album toned on the obverse only. It is pretty subtle, as the picture on the left shows. I also recently had this graded by PCGS and it did slab.

I am not sure I actually completed this challenge to your specifications, I could probably juice it to make it look more unreal, but the picture on the right is definitely not how the coin looks in person.

Ooo I like this idea! Can't wait to see what people come up with. rgCoinGuy - Very interesting photos. I could see it now that if you were to sell that coin on eBay you'd get twice as many bids on the juiced picture.

UtahCoin, yours is too easy to tell. The slab is a different color in the second picture (BTW, I like the first picture a lot more than the second)

Here you go, I tweaked the the slab color....

This should be fun!....

I acutally made this for when I posted a recent purchase on the TCCS forum.....some folks love images that to me don't look real so i was fooling with them








The coin looks like this without the additional saturation...

Here is one Ive had in my album for probably over 20 years. Top is natural bottom is juiced

pretty good examples thus far.

i wonder how many of the "juiced" images would be called AT if they were shown either in an auction listing or forum thread?? i think this sort of highlights two problems with online pictures when we each see color a little differently: it may be tempting to manipulate the image to make it look closer to what we "see" and perhaps with different monitors and different adjustments on them we end up with varying images that we each think are correct.

I don't understand all I know about this stuff but.... I can tell you a couple of times I've been surprised... no, shocked at how different the same exact picture can vary in appearance from one monitor to another. I don't know why that is, but I do know it is.

I can tell you that (on my monitor) each of the coins "in hand" looks somewhere in-between the flat "raw->jpeg image" and the juiced "raw->jpeg->brightened->sharpened->saturated" image. Though I use sRGB profiles for every image I save I know for a fact that every final picture is still going to look different on my macbook pro screen vs. my dell external screen vs. my sons toshiba screen vs. the apple cinema display on the family computer. It simply cannot be helped.

- Default Gamma in Pre-Snow Leopard Macs is set to 1.8 vs. the 2.2 which has been standard on Windows/PC machines for years (this is a holdover from the Mac's pre-press days)
- Color temperatures differ wildly even on the exact same model screen.
- The older a person gets the more contrast they want in their computer screen. It is a fact of aging that cannot be helped. One which will drastically change how a 20 year old sees a coin vs. a 40 year old vs. an 80 year old.

"Owlsely and her colleagues determined the contrast sensitivity functions of 91 people aged between 20 and 80 3. Everyone underwent extensive eye examinations to ensure that subjects with defective vision were either excluded from the study or given glasses that fully corrected the problem. The results, some of which are depicted in Figure 3, showed that from the age of 40, contrast sensitivity at higher spatial frequencies starts to decline until at the age of 80 it has been reduced by up to 83%!"

All that said I still think it is pretty easy to tell the difference between many AT vs. NT simply by color progression and pattern. And further that most juiced images are easy to spot.

Lets just start with this photo.
