Xu's entry showed cells with abnormalities and features that appeared and disappeared, which an associate professor said were classic indications of AI generation. A PhD student at UT Southwestern Medical Center said the source image appeared to contain a watermark indicating AI generation. Xu said AI was used only to distinguish and visualize features in grayscale images during post-processing, but Nikon's investigation found he violated competition rules. The title now goes to Nguyen Nam Nhat of Vietnam, and Nikon says it plans to revisit its rules and evaluation procedures. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How was the AI-generated video in the Nikon Small World in Motion contest detected? Scientists noticed cellular structures and cilia that appeared and disappeared in ways not seen in real biology, a classic AI artifact. A PhD student at UT Southwestern Medical Center also found a distinctive watermark on the source image indicating it had been AI-generated, which led Nikon to investigate and strip the winner's title. _Spotting AI artifacts in media matters beyond photography contests; daily.dev surfaces reporting on AI detection methods for developers tracking the issue._ ## Community take How the wider developer community reacted, aggregated from 1 discussion and 67 comments across hackernews (as of 2026-10-25). **TL;DR:** Most agree the disqualification was justified once evidence of generated artifacts (cilia appearing/disappearing, a possible AI watermark) surfaced, but the thread spirals into a broader, heated debate about why people use AI and whether it constitutes cheating versus just another tool. **Sentiment:** 5% positive · 30% mixed · 65% skeptical **The case for** - Some argue AI-assisted camera features (autofocus, denoising) are already widely accepted and not fundamentally different from generative post-processing. - A few see heavy use of diffusion models as a legitimate creative tool for restoring old or technically limited photographs. **The pushback** - Several commenters say the video's artifacts (features popping in and out) were an obvious giveaway of AI generation. - Many distinguish between deterministic post-processing (denoising, exposure correction) and generative AI that fabricates details not present in the original capture. - Some frame using undisclosed generative AI in a contest as a rules violation and a sign of broader laziness or lack of integrity. - One commenter notes competitive pressure (publish-or-perish incentives) likely drives researchers to take such risks despite the ethical problems. **By community** - hackernews (heated): Discussion splits between those condemning the use of generative AI as cheating and those arguing the line between acceptable processing and generation is blurry, with a side debate on AI's broader effect on creativity and effort. **Hottest debate:** Where the line falls between legitimate AI-assisted photo processing (denoising, autofocus) and generative AI that fabricates image content, and whether that line should disqualify entries. **Open questions** - Should photography contests define clearer rules distinguishing deterministic processing from generative AI fabrication? - Was the disqualified photographer intentionally cheating or simply not disciplined enough in how he used AI tools? **Highlights** > I was surprised at how obvious the AI was. Cilia do not, in fact, pop in and out of existence while moving around. > — [odo1242 on hackernews](https://news.ycombinator.com/item?id=50233012) > > AI-assisted autofocus, subject tracking... This is already present for the last decade. It's the foundation which makes "sports DSLRs" possible. AI here is not what we know as today's "AI". These are specialized models baked into DSPs to run at inhuman speeds. In Sony's case it's phase data, image itself, information from the lens, and sometimes the accelerometers on camera. This is not making something up from thin air. AI assisted autofocus is smarter phase detect autofocus. Subject tracking is an educated guess for where the focus shall move, based on movements in the image. My ~20 year old Nikon D70s has a 1004 pixel "scene detection and metering" sensor "trained" on thousands of images to make educated guesses in full-frame metering mode to exposure correctly. This is in no way helping or altering the image in any way. Same for faster autofocus and object tracking. Exposure, white balance, noise reduction, color correction, HDR et al can be all achieved with deterministic and traditional algorithms as well. Some of these processes have history in film photography and carried over to digital from analog. Some photographers are famous for their darkroom treatment of their shots during development. Processing an image with deterministic algorithms using the data in the raw photo is fine. This is how darkrooms work as well. However, guessing things, altering images by adding something which was not there and claiming otherwise is not acceptable. This can be a new element inside the scene or pixel details which was not resolvable by the lens/sensor/film to begin with. Both are "photomanipulation", not photography. > — [bayindirh on hackernews · 2 comments](https://news.ycombinator.com/item?id=50233255) > There has always been some fuzziness behind what counts as "genuine photography" and people have been gatekeeping it for decades as new camera tech became available. Generating statistically likely pixels given the context of the image and massive amounts of (untraceable, stolen) training data definitely seems like a different kind of post-processing than what you'd normally do in an editor, or even changing pixels by hand. Nikon gets to gatekeep their competition however they like. Personally I think it would be a shame to reward photographers for the work they do outside taking the shot and light editing/compositing. What's the point of a competition if you're not going to enforce high standards and challenging constraints? > — [ajs1998 on hackernews](https://news.ycombinator.com/item?id=50234566) > Publish or perish. The stakes are incredibly high. Cheating may be the difference between keeping and losing your job. Especially since everyone else is aware of that. If you don't take the risk, you will lose to someone who did and got away with it. This researcher is in China, where I gather the competition is even fiercer than in the West. I do not know that for a fact, but if it is true it makes it even clearer. Viewed that way it's not foolish. It's actually mandatory. And it's just going to get more prominent as the AI makes fewer mistakes, and competitors get better at spotting and removing them. > — [jfengel on hackernews · 1 comments](https://news.ycombinator.com/item?id=50232726) > Why don’t we allow printers in a painter competition?
