Want realistic AI images in Midjourney? Just add a camera filename


In brief: Midjourney recently launched a new version of its generative artificial intelligence program that makes it almost impossible to distinguish digital creations from real photos, especially when leveraging a clever prompt trick.

Over on X, user Min Choi shared a series of images created with Midjourney v7 using a clever hack. By appending a generic camera filename to the input prompt, Choi was able to get the AI to spit out photo-realistic images time and again.

According to Choi, these 100 percent AI-generated people are not real. Presumably, the images are straight out of the AI and have not been doctored in any way. Try as I might, I was unable to detect any anomalies in the samples. Can you spot any AI glitches?

As PetaPixel highlights, generative AI programs like Midjourney are trained on real photos and many of them have default filename formats. CR2, like Choi leveraged, is Canon’s last-gen RAW image format. Adding text like “IMG_7384.CR2” to an AI prompt along with “casual selfie at [chosen location]” seemingly tricks the system into generating incredibly lifelike images.

Interestingly enough, it is also possible to enter a filename into Midjourney v7 without an additional prompt and get something totally random reach time.

The trick isn’t limited to Canon’s image format, as others were also successful in using the HEIC extension to create photorealistic pictures.

Worth noting is the fact that the filename trick is not new. Several months ago, a Reddit user shared several images created in an earlier version of Midjourney using a similar filename prompt. These weren’t of people, but the results were still rather impressive.

Midjourney version 7 is available now. According to the company’s description, it affords richer textures and more coherent details – especially in bodies, hands, and objects. The update additionally introduces Draft Mode, a way to prototype images at 10x the speed and at half the GPU cost. Should you create a draft you like, simply tap the Enhance button to run a standard generation on it.
