Spinnaker
Tower, Portsmouth – Rick McEvoy HDR Photography
This
is the third image image of the Spinnaker Tower.
The first image was taken on
my
Canon Eos 5D using my 17-40mm F4 L lens with an exposure of 1/100th
of a second at f16, ISO 400, the second image was taken using an exposure of
1/200th of a second, f16, ISO 400. This image was taken with the same
settings but a shutter speed 1/50th of second. By reducing the shutter speed by
one stop from the correct expsoure I have doubled the amount of light reaching
the sensor, resulting in an over esposed image, capturing the detail in the
shadows lost on the other two esposures.
I use
auto-bracketing on my camera to produce a set of three images, the first one the
correct exposure, the second photograph one stop under-exposed and the third
shot one stop over exposed. The reason for this is that quite often it is not
possible to capture the whole tonal range in a scene.
What I am going
to do is merge the three images, identical apart from the exposure. I am going
to export them from Adobe Lightroom into Photomatix 4.2 and produce a single HDR
(High Dynamic Range) image.
