I received a lot of great responses to the image I posted yesterday of the National Building Museum HDR image. First of all, this place really lends itself to the HDR process so I kept the tonemapping fairly simple so that the HDR effect was pretty low-key. I used 3 images shot in RAW on the Canon T1i to create the original RAW files. The images were then merged in Photoshop CS4 using the Merge to HDR command from Lightroom 2.0. The tutorial picks up in Photomatix Pro after I have already made my tonemapping adjustments and then follows along as I take the image into Adobe Camera Raw and finally Photoshop for some noise reduction and image sharpening. These are two areas where Lightroom just can’t deliver the goods. For the noise reduction I used Nik’s Dfine 2.0 and then applied sharpening using the high-pass filter. Check out the video to see the entire process.
