There is no shortage of technical photographic advice out there on the Internet—buy this camera, read this book, and memorize these rules of composition and you'll be great! But the process of becoming a great photographer is more subtle than that.

For us sighted folk, it's difficult to imagine an image-less Facebook News Feed, where a screen reader tells you that your friend uploaded a photo... and nothing more. But thanks to Facebook's new "automatic alternate text" tool and the power of artificial intelligence, that reality is no more.

If you think male and female photographers sometimes have very different styles, the reason might go beyond their tastes and approaches to shooting.

According to the findings, men are more sensitive to moving objects and seeing small details, while women tend to be sharper in seeing color changes.
