I have made claims in the past about how much I dislike Photoshop’s HDR toning.  That is still true, I am not a fan of the HDR toning, but  I do love the 32 bit workflow in combination with Adobe Camera Raw.  The results can make for some impeccable HDR images that are both very realistic looking and free of the typical HDR Noise.  While the effect is not as grungy as many might care for with HDR it is definitely something to consider in your HDR workflow!

I find it particularly useful with sunset and sunrise scenes as they can be tricky in many tone mapping programs.  Check out the quick workflow, Before-and-after, and the Video Tutorial if you are interested!

My 32 bit workflow is a 6 part process.


  1. Make the 32 bit file in Photoshop
  2. Save that 32 bit file as a TIFF
  3. Modify the 32 bit TIFF in Adobe Camera Raw (feel free to use Lightroom as well)
  4. Save it as a 16 Bit TIFF
  5. Modify the 16 Bit TIFF in  ACR again.
  6. Make typical post processing adjustment

Most people think I am passionate about Photography, but in reality I am not.


Wait, before you freak out, you are on a photo site, I am addicted to post processing. To be more specific, I am addicted to workflow efficiency and cracking the codes to complex systems. That's what I do here, crack the code to photo post processing and present it in a concise way, for you :)
