Upload & Sell: On
I don't have Lightroom, but in Adobe Photoshop Elements 9 the EXIF info only shows whether the flash fired, if Red Eye Reduction was on, and if "Compulsory Flash Firing" was on.
In Digital Photo Professional I see whether the flash was on or off, and if Flash Exposure Lock was used.
I do not see any information on flash power level, flash exposure compensation, multiple flashes used, etc. in either program.
