Lightroom not showing proper exposure with different ISO settings

[Bob Coulter]

Hi, I'm having a problem with Lightroom's Photo Merge to HDR. I'm using a Fuji XPro2. I took some shots using "ISO bracketing". When I look at the 3 bracketed pictures in Lightroom ISO 200 and ISO 400 look identical, they have the exact same exposure level. The 3rd shot at ISO 100 looks darker. If I look at those same pictures in Photoshop, they have 3 different brightness levels that match their ISO settings. WHY!?!?!?
Thank you,

Bob Coulter

Hi Bob,

Sorry that the HDR merge using Fuji XPro2 in Lightroom shows different ISO settings. 

Which version of Lightroom are you using and does the problem only occurs with the Fuji camera you're using?

I'd suggest that you take a look at the below discussion and let us know if that helps?

Merging three photos will the same exposure but different ISO is totally useless. That will not give you an HDR file, but a file with exactly the same dynamic range as the correctly exposed single exposure.
