Recently, I took a trip to the local airport to photograph planes. My goal was to create a series of tone mapped HDR photographs. I’ve fallen head over heels for Photomatix Pro, but keep encountering the same problem––a noisy, sometimes blotchy sky. Although it’s possible to process a scene twice––once for the subject, and again to produce a noiseless sky––this approach rarely satisfies me. The noiseless version of the sky possesses weaker richness and contrast than the noisy one. In today’s tutorial, we’ll examine an approach for dealing with this challenge.

Re: reducing noise in HDR
I bring all images into photoshop and run Define2.0 on each one and save those as TIFF files which can be used in Photomatix to generate an HDR, without noise.

Mark, thank you for this great tutorial. I also use Photomatix Pro and fight with the noisy skies. This is the such a great and simple way to deal with this issue. You truly are a PS Genius.
