no. they allow u to use your on-camera flash, but if u want to do strobbist way, they want u to apply for permit.
but i must say they are already very very kind in this respect. other building will just ask u to go away, be it on or off camera flash, got flash , no flash ... they dun care, just get out and shoot else where..
yep .. i was warned by the security guard before. as long as its off camera flash, you need permission from the management.. tthe guard was kind enough and i told him i was finishing and he told me, "Ok i walk there for a while but when i come back you must stop already " :thumbsup: nice guy... we packed up and headed to helix bridge area
