Maybe it's just my eyeballs, but it looks like the <1 photon/pixel result was kind of fuzzy vs. the higher photon count image (cf. wasp wing).

If the idea is getting targeted bits of information about an object, as in whether a feature is present or absent, the very low photon image might meet the need.

However, with photography as art, the requirements for image resolution would be much higher, much more similar to the multi-photon image examples.

So it would appear mileage varies: the minimal photon images suit the minimalist domain, but an ordinary high-resolution image would require many more photons/pixel to get the expected result.
