Hi Folks , today I have another HDR rendered image , this old barn has been a prior subject that I have uploaded , fortunately I was given to taking a goodly amount of shots of it to play with ;-)
my first upload of this barn was done with simple photoshop processing seen here , not a particularly popular upload , but mostly color true , my second and third upload featured more extensive rendering into Black and white images , seen here and here
in this image I used Photomatix pro to render three images processed from one Raw file , I like to use one raw file because it is a nifty way to avoid problems from non-static elements in the image things such as moving clouds and swaying foliage do not exactly work out for the best when merging exposures , not exactly the best method for HDR but really good for just practicing the process and learning what types of scenes are suited to multiple exposure efforts ;-)
one thing that seems to recur as an issue in the HDR process is sensor grain , particularly in the area of the sky , to deal with this I duplicated layers then used the magic extractor tool in photoshop elements 6 to remove the sky from the upper layer , with the color difference between the sky and the rest of the scene this was very easy in this image , then using that upper layer I used the quick select tool to select what was now transparency in the sky , changing over to the lower layer I refined the selection to only include sky then simply used the denoising option 'remove dust and scratches' , on an area like the sky such a strong denoising measure works fine , removing the grain from the sky not only improves the aesthetics of the image but also make the file compress better for uploading a bunch of grain in the sky is really just seen as detail by a jpeg compressor and can really drive up a file size , I think the same thing happens doing a 'detail enhancement HDR' the software views noise as a detail and tries flatter it with the other real details , I think that learning HDR will require me to learn better more advanced noise removal in the long run...
thanks for stopping in , hope that you like it.
regards
