Commentary #4
I shot this at the same location as the other waterfall shot I posted last week. Here I have walked up the side of the gorge to include the trees in front of the falls and the rocks in the bottom right. These two features on opposite corners help to anchor the eye into the photograph and create this tightly framed composition.
This is processed using a technique called HDR that I have touched on previously. This involves taking 3 seperate exposures at capture - in my case doing them in a sequence of -2, 0, +2 stops. When blended later these three exposures provide information on the respective areas they capture, and produce a result with increased dynamic range. Have a look at the link at the bottom for more information on HDR.
This time I was shooting at f/16 to provide sufficient depth of field to render back-front sharpness. A total exposure time of 1.2 seconds including all 3 exposures gives the flowing water the flowing quality I am always looking for .
One thing to note is the blue-ish tinge to the water. This was created in the HDR processing and it is quite effective. This hue is carried into the back walll of the gorge on the top-left. The image has also had a slight vignette applied to it, whereby the corners are darkened slightly to frame the photograph even more tightly.
One thing I have noticed when embedding these photos in these commentaries is that the images look very compressed. They do not have this crushed effect when viewed full size.
