![]() I compressed it at Photoshop's lowest quality JPEG setting so that the artifacts would be really obvious even after TOP's TypePad interface gets done with it (fingers firmly crossed). I created this JPEG for illustration purposes from one of my original photographs. But it can work many small miracles and that can be the difference between intolerable and tolerable image quality. It cannot take a truly crappy JPEG and turn it into a fabulous photograph. Build the rules it invents into a standalone program, and you have JPEG to RAW AI. Enter Artificial Common Sense-train a deep-learning network to recognize what the mangling looked like and undo as much of it as possible. You know it's not supposed to be contoured, it's supposed to be smooth. It is true that you can't get something for nothing, but a JPEG isn't nothing, it's just a badly mangled something. Simply switching the image mode from 8-bit to 16-bit doesn't get you out of that one, because the contouring is baked into the image. Because, eight bits! The dreaded picket-fence histogram. Like, say, punching up a dusky and hazy blue sky and all of a sudden the contouring that wasn't visible in the original high quality JPEG becomes unacceptable banding. That's just fine, until you want to manipulate some photo in a way that pushes it outside of its comfort zone. As in, my camera had a bad hiccup (or I did something dumb-take your pick), reset itself to all its defaults, and I didn't realize I was photographing in JPEG instead of RAW mode.Īlso, I know that some of you prefer to photograph in JPEG mode (I don't judge). Sometimes it's a really crappy JPEG and what they want to know is whether I can turn it into a semi-decent photograph.Īnother reason is that, umm, "stuff" happens. Sometimes the best file that a client can provide is a JPEG. Remember that two of the pillars that make CteinCo the multinational powerhouse that it is are custom printing and photo restoration. So.why would Ctein, the Guy Who Does Everything in RAW, even care about a program like this? One reason is that sometimes it's not my call. Okay, the class is a lot smaller you can all move in closer so I don't have to shout. No worries, it won't be on the final exam. If you have no interest whatsoever in working with JPEGs, you can skip out on this column and go do something more productive with your time. Hand it a JPEG of your choice and it will generate a RAW file (or 16-bit TIFF, if that is your preference). The last of my Topaz Labs reviews concerns a nifty little program with the intriguing title of "JPEG to RAW AI." It is, as they say, a one trick pony, and the trick is in the title.
