“Easy way to answer that question.
“Buy it, take the crappy JPG from Orly and see if it can produce the same level of resolution and quality as the TIF image.”
I notice that you have declined to deny that it may be possible to use image resolution enhancement software to double the JPEG resolution of Orly’s image, take a picture of it as a TIF file and then falsely claim that only you could possibly have the much higher resolution original.
Per Topaz promo:
“With Topaz Vivacity, you can: ...(5) enlarge images 2X or more and still maintain visual clarity...”
I’m not saying that you did this, but that it could have been done. What folks with enough money or access to intelligence resources can do with image enhancement is amazing, after all.
