If you're not really across the trend, users stand infant of the camera, strike a sexy pose and the screen fades into a deep-red Bond filter. But because the world can be a terrible place, there are a bunch of people on Youtube instructing others on how to use editing software or apps to change the contrast and colour in a way that reduces the silhouette effect.
The editing isn't able to revert the videos back to their original form, but can reveal more details.
What this means is that anyone who has recorded the silhouette part of the video in less clothing or lingerie, the editing can reveal their bodies.
Reddit. A subreddit for posting edited videos, called r/SilhouetteUnfiltered, has already been banned. At least two Twitter accounts that were editing TikToks on request and shaming the people in them have been suspended.
Now, women are warning each other on social media about the hack, and advising people that whatever they are (or aren't) wearing may end up being seen.
"Just make sure you're being cognisant of what you're wearing before you do all the editing for the final product," says @lostvsnryshots.
