glad u liked them!
i didnt use PS to give the pic a blue tone, in fact i used ps to lessen the blue tone. i set the white balance on the cam to tungsten for the blue effect. actually the blue lighting would come ard 8-8+ i think, experienced such lighting at labrador park before... i wanted to be back home for dinner, so i thought wad the heck
for the urban escape shot, the shutter was 2s, iso 800. enough to create the wave-hit-rocks effect without blurring too much... couldnt do lower iso cos the whole tripod was in water n waves were strong, longer exposures will be blurred. camera safety is another factor too. some ps was applied to slightly darken the orange sky. for part of the 2s exposure i used my hand to cover the sky too. but personally i was slightly disappointed due to the distant factories spoiling the landscape, and the high noise level when printed out in s8r.
