Kate Middleton's Photoshop Fail Had 16 Edits, New Conspiracy Theories

Kate Middleton's Photoshop fail reportedly had at least 16 editing mistakes that experts could see ... and with the release of a new pic, more conspiracy theories are mounting.

The Princess of Wales' UK Mother's Day tribute has been analyzed in-depth by several different photographers who weighed in with the Daily Mail -- who collectively highlighted more than a dozen blunders Kate made while manipulating her controversial pic.

Upon closer inspection of the viral image -- which shows Princess Kate posing for a photo with her children, Prince George, Princess Charlotte and Prince Louis -- it's clear that quite a bit was changed after reportedly being saved twice on Photoshop.

Here is a full list of the spotted errors ... Charlotte is missing a part of her left sleeve; Kate's zipper is screwy; Charlotte's hair is cut off; Charlotte's skirt juts out; Charlotte's knees are blurred; Louis' sweater sleeve is contorted; Louis' right thumb is blurry; indent/distortion on the ledge; step behind Louis is distorted; Louis' finger looks cut off; George's blue sweater enhanced; Kate's hand out of focus; George's sweater sleeve has unusual lines. Phew!

With all these changes made ... many are now leaning into a new theory about when this photo was actually taken -- and what everyone in the pic was actually wearing at the time.

Online sleuths went back to December, when a video was posted to the official YouTube channel of the Prince and Princess of Wales -- which shows Kate and her kids doing some charity work ... in outfits that some believe seem to match up with this Mother's Day photo.

The colors of each person's clothing are different than what you see in the picture in question -- but some have suggested that's where the real alterations lie ... namely, color swaps.

There's another conspiracy theory floating around as well ... and this one has to do with the photo that surfaced Monday showing Kate and Prince William in a car leaving Windsor.

You can't see Kate's face clearly in this new shot -- it's almost as if she's looking away -- and because of that ... some have made the leap that even if this photo might be manipulated ... even though we've been assured by the photog/agency distributing it that it's authentic.

The reason people suspect this pic might be Photoshopped, too, though has to do with the fact Kate's appearance here mirrors an older photo she was in from back in 2016 ... when she was snapped standing with Will and Prince Harry. Some think the angle/image are identical.

It's an interesting thought, but TMZ's art department tried lining up the two images -- as many have already done online -- but they don't blend into each other perfectly, specifically around the ears. In other words ... it is very likely these are, in fact, 2 different photographs.

TMZ's art team tried duplicating the edits ... and, unfortunately for conspiracy theorists, it doesn't line up. So ... despite the speculation, it does seem to be different photos.

That's not gonna stop the tinfoil hat people from continuing to gossip/speculate though ... and anything short of seeing Kate hop on camera or come out for an actual appearance probably won't appease everyone who's fired up about this.
