Picture Of 70B's With A 65 For Contrast

I took a picture of 5 stamps which I think are 70b's. There is a 65 stuck in just for contrast. The one 70b I own which has been certed is not shown separately.
Any comments?

Sorry, I did put the certed stamp picture in first.

It is not possible to compare a scan with a picture of five stamps. If the five stamps and the certified copy had been scanned together, it might be possible to find stamps matching the certified stamp. Photographing the stamps and the reference against a cluttered background is not an effective way to compare colors. The color balance in the digital photograph suggests that the five stamps are greenish color changelings. Is a cell phone camera useful for color comparisons? The jury is out.

All I can say is good luck on identifying the color of this item. RH White has (3) color plate photographs just concerning this issue. Below are those plates copied from the Encyclopedia of the Colors of United States postage stamps, volume 1. (Scanned at 600 dpi ... sorry for the background, but you get the general idea of the colors.) They even show some chemically altered copies to show you how easy it is to manipulate the colors on these.





Here are the various 70b scanned at 2400 dpi, but reduced by our Free Image Optimizer. Good luck.

Does anyone know when they first started documenting the different shades of this issue? Were there printing ink receipts or anything along that line?

Thanks for comments. I took a separate scan with the certified stamp in the center. After doing scans and photos and then trying to identify colors from the scans I can see why you experienced collectors say "get it in front of an expert" if you want to determine color, although just putting it under a good LED ring light really brings out the color (especially the shades of 64)

Thank you, Partime, it's always interesting to see some page of White's book, as it's not possible to buy it here (or anywhere). I have best results in uploading when I reduce the size in any image software (to for example 800x400px), save as JPG with compression about 80-90% and then upload it in a size below 200KB. Then no optimizer works there and no such huge JPG artefacts appear like above. Would be interesting to see the 24c stamps without them, of course :).
