Dear Aksana Zaretskaya ,

A photorealistic human texture demands human facial proportions, or the computer generated character can result in the uncanny valley. Abnormal facial proportions, including those typically used by artists to enhance attractiveness (e.g., larger eyes), can look eerie with a photorealistic human texture.

Dear Shafagat Mahmudova ,

Recently, at a forum dedicated to the latest achievements in the world of advertising, I had a conversation with one of the specialists in AI generation of advertising images. He stated his position something like this:

- since the advent of photo correction, classic photo images in advertising have been transformed to make them more attractive. For example, the skin was smoothed, the neck was lengthened, the eyes were enlarged, etc., which ultimately led to the creation of rather specific images that people perceive as role models.

- today, advertising customers often prefer generated images because they show a greater sales effect than classic photos, even if they are processed in a photo editor

- one of the problems this specialist named is that neural networks today generate too plausible images, which often lack some magic of an ideal world, and specialists sometimes have to manually add implausibility to make advertising effective

- video generation is still imperfect and its use in advertising is still complementary, entertaining in nature

It turns out that the implausibility of images can and does work for attractiveness and increases sales. As I understand it, it was previously believed that implausibility repels the consumer. Here I see a gap between practice and theory: scientists say one thing, and advertisers see the effect of another. It seems to me that we somehow incorrectly understood the force of the gap, which we called the "uncanny valley". It works somehow differently and it should be understood not so narrowly.
