Eventually something has been posted after a long gap! .
The Burrard Bridge in downtown Vancouver. This shot is an HDR photo, combined of 3 exposures -2,0 and +2 EV. The focal length and F Number kept constant and used tripod and remote control to minimize the camera shake.
marvelous shot! i'm impressed you got it from just 3 shots, it usually takes me 5 or 6 shots if i want to avoid grey noise (of which you have none at all). great capture
thanks a lot photofairy! , I actually waited for clouds to cover the sun to reduce the bracket between highlights and shadows and basically the contrast. For "Coal Harbour" [link] since it was a direct sun light, I had to use 7 shots! Thanks for your comment .
