Spinnaker Tower Portsmouth

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.
