That's a little close for photos...

Sure. Not from that angle.
It should be around that location of the riverbank indicated by the distance ruler in the Google Maps imagery that I've posted just above. The view of those photos is actually directed at/about parallel to the longitudinal direction/length of the assembly hall.
Also, things that we're used to looking small on photos can indeed be pretty big when viewed while physically located close enough (or zoomed in close enough). And less we forget - The 054B is a 5000+ton FFG.
We have seen similar images in the past of 054B and 054A under construction at Huangpu many many times.View attachment 178270View attachment 178271
