Why is he using Flash in broad daylight?

I saw this poster on the side of a Sukleen truck so I went into the App store to download the app and see what it’s about. As it turns out, it’s an app where you can take pictures to report any cleanliness issue to Sukleen directly and point out its exact location on the provided map. You can also follow up on the issues you’ve raised to see if Sukleen took action or not. Added to that, there’s a sorting guide that gives you tips on how to reduce, reuse and recycle at home and in your office.

I think it’s a pretty useful app but from what I understood it’s only available on the App store which sucks. As far as the marketing campaign is concerned, I wish they had gone with something simpler and showed an example of what we should be taking pictures of.
