A while back I saw a Scott Kelby video on YouTube about the HDR functionality in Lightroom and that in Photoshop. I had assumed that they were the same prior to seeing his video but he showed that the Photoshop version of the HDR was significantly cleaner than that in Lightroom. I was interested in how this could be but I wasn’t too concerned. The Lightroom version was so easy to use I figured the impact was not so much that it would show up in my shots.
Then, I found out I was wrong. I was in the cockpit of the Comet at the Museum of Flight’s restoration facility at Paine Field. I took a sequence for HDR because the cockpit is very dark but the view out of the windows is much brighter. It isn’t particularly important since the view outside is nothing special but I did it anyway since I was there. The lighter shot had quite a bit of shadow noise and, when I created the HDR in Lightroom, the noise was very conspicuous on the finished version. I decided to try it in Photoshop to see what happened. The difference was significant. I include both of the full shots as processed along with the section of cockpit shadow so you can see the impact.
