HDRI photography – stained glass window

Category : Photography November 15, 2011

Bacon's College stained glass window (photo composite)I needed to photograph an image of this stained glass installation which was to be used for a Christmas card. The three panels are backlit by three vertical fluorescent tubes and covered by a protective plastic screen. I found I couldn’t get a decent shot of it despite trying a range of lenses and settings. The fluorescent tubes were prominently visible in the shots, and the more richly coloured segments let through far less light than the brighter ones, and looked dull.

To compensate, I mounted a Nikon D5000 with a Nikkor 50mm 1.8 on a tripod, and took three RAW shots bracketed 1EV apart. I combined the images in Photoshop CS5 using Automate > Merge to HDR Pro and spent some time tweaking the plugin’s settings to create an image which gave a more equal prominence to the colours, while reducing the highlighting caused by the flouro tubes. I used Photoshop’s Lens Correction filter to remove some slight barreling at the edges, and Curves to tweak the overall contrast.
