[QUOTE="STM, post: 275919, member: 12827"] This is just a time (B) exposure. The reason some of the cars appear stopped is that traffic may have stopped in that lane for the duration of the exposure. Judging from the length of the light trails, exposure was maybe 2 seconds. I doubt it is HDR as that requires at least three exposures; base exposure and 2 others at least 1 stop over and under. There is no way you could have gotten the traffic to line up for those three exposures For exposures like this I will lock the shutter open, with a black card in front of the lens. Exposure like this doesn't have be super [FONT=Calibri][SIZE=3][COLOR=#000000]precise so I will usually just count out the exposure. Placethe card back over the lens and unlock the shutter. By keeping the shutter openbefore and after the exposure, you will eliminate any unsharpness and ‘doubleimages’ due to vibration. [/COLOR][/SIZE][/FONT] [/QUOTE]
