As mentioned that i don't always shoot landscapes but rather more on birds for the moment so iam actually using my own experiences to share here. Not sure if there is any degree in differences between them?
I do agree to share with those who are responsible and reasonable.
But how do we know if the person is responsible or not? Personally if the location is for public access,I will share and remind them on the things to take note. If i ever knew they aren't being responsible,I will think twice in future if i wanted to share with them or not,and not assuming everybody is irresponsible and not share which I think is pretty unfair. Sometimes it takes some courage to ask being feared getting rejected or scolded,yes i kena scolded before..lol
Iam not sure if u have ever asked others on where some of their photos are being shot at?
When u found a nice location do u post it in any group or your own FB to share or just keep it personally and share with close friends only?
Did anyone asked u before on the locations?
