Thanks to all for taking the time to respond. Rexer John I'm using the D5100 and have been pressing the info button to turn off the screen in this case. carguy unfortunately I do have that setting turned off. Rodbender I would prefer to not have to resort to flipping the LCD around. But alas while the D5100 does not seemingly provide a setting to disable the display in this scenario. I did stumbled upon a beneficial side effect when the shutter button is pressed half way, it will inhibit the display from turning on. So as long as I half press and hold the shutter button, followed by pressing the fn button and using the exposure compensation dial to tune in the ISO value I desire. Then release the fn button before taking the shot or releasing the shutter button, results in me not being temporarily partially blinded by the LCD. Thanks again for all who responded, and to those who would have responded with their insight.
