I could think of a couple of different reasons. In the first place, there's the increasing ease (whether perceived or real, but let's leave that) of creating high quality photographs. Young photographers can hang their hat, so to speak, on the relative technical skill required to produce a good still life. At the same time, the still life is also (conveniently enough) a genre with a long tradition in the history of art, and photographers can use this to position their work within a broader field. Still, the usage of intentionally bad objects ("useless," as Krijno calls them) makes it possible for the photographers to create a kind of nostalgic connection with their audience. (Another still life photographer, David Brandon Geeting, has taken an image of a BIC lighter, which I'm sure will have some connotations for many Americans.) So, while this work is able to reference classical art—and Krijno is doing exactly this in his "Venus" photographs—it's also not difficult to grasp.
