    Default 1st HDR attempt

    Went to Chinatown early this morning, to try out some HDR.

    came back and processed the following 2 sets using photomatix.

    Comments?







    Anyway, i am seeing a very high amount of noise generated from the HDR photos. Is it common? anyway to reduce it?

    Hi luntut,

    You might want to work on the curve a little more. As it is now the shadow area is too light and looks weird, especially the second picture.

    To John E,

    For an explanation of noise, please see this explanation on dpreview.

    HDR means "High Dynamic Range" and is a photography technique of using multiple exposure of the same scene to extend the small dynamic range limited by the sensor of the camera. Here are some links for more information (you're welcome to google your own links):

    Are you using photomatix or CS3 for creating the HDR?

    2nd one looks much better and more natural. This is of course assuming that you're looking just to extend the dynamic range and not to create a surreal picture (otherwise the 1st one is more surreal). Maybe an enhancement is to darken the shadow casting on the road slightly more, as it is a bit too light and bluish now (seldom see light bluish shadow unless reflected by blue surface).

    actually i am intending to use HDR to create a more natural looking image with an extended dynamic range. not really into surreal effects yet.

    think i need to tweek the settings more. let me see how to get a decent looking darker floor.. but if i darken the shadow, wun i darken the buildings too? cos the buildings are wayyy tooo dark in the original version...

    thanks ziploc in advance!

    Hey no problem at all, we're all here to share and exchange ideas.

    Yup the buildings will be a bit darker also. But I guess that is ok since I find them a little too bright now. Just tweak it such that the buildings and road are dark enough (hence looking more like in the shadow) without losing much details. You might also want to try reducing the color saturation (you have a velvia 'orange man' now ).
