I think it's great that this service is available. I myself could have used it when working in several situations where electricity and communications were very scarce resources. However stylistically I prefer the originals in most cases, which include more details and information. As Nacthwey has done with the "three zombies" photo (https://plus.google.com/u/0/s/nachtwey%20max%20hodges?hl=en
), amping up the contrast to get this gritty, stark, more abstract style has become a veritable cliche and can distract from the content as often as it can compliment it.
