HI John,
The way I read it is that rule 4.3 applies to any and all submissions.
4.3. You confirm that each person depicted in the photograph has granted permission to be portrayed as shown—and has the right to grant that permission. Any costumes, props or other materials used must be rented or borrowed with the permission of the owner, and all other relevant permissions must have been obtained.
Whereas Rule 4.4 is a further rule specifically applying to "news" et al type images.
4.4. Images that purport to be “news” photographs, reporting, photojournalism, or documentary photography, should comply with the ethical guidelines of the National Press Photographers Association (
https://nppa.org/code-ethics) in general, as well as those proposed by UNICEF for ethical reporting on children .......
Quite how street photographers will obtain permission from (identifiable) members of the public in their images is beyond me, this sounds like a legal clause to cover LensCulture's onward use of the images and prevent them being liable if anyone in the picture takes out any action against them.
It's a shame that photography has now come to this imho, I expect it is the 'Net and the explosion of digital photography with images everywhere which has bought focus on the legality of snapping away on the street. Enjoy it while you still can...
