Hi Rob, Thank you for your help. The problem was the creation of the small rectangle. I was clicking on the HDR image where the luminance meter was focused, but I didn't realize I needed to hold down the left button mouse button and draw a rectangle/box.

How did you create the image you're trying to calibrate? - Rob On 4/21/16, 8:54 AM, "Andrews, Ben" <[email protected]<mailto:[email protected]>> wrote: hello all, I am experimenting with high dynamic range imaging and glare analysis. I am attempting to input a luminance value (cd/m2) into an HDR image with Photosphere software. The ultimate goal is to save a .hdr file to bring into Evalgare. I've used an luminance meter to record the cd/m2 in the room and now I'm trying to pick that same spot on the HDR image and calibrate the luminance within the Apply Menu of Photophere. Trouble is the Apply button is grayed out. Has anyone experienced a similar problem? Any advice would be much appreciated. Thank you.
