Images as emitters constantly come out dull. White emission not actually white. What am I doing wrong? I have been using Blender for a while but keep hitting this problem that I don't understand.  First of all, I don't understand why I white emission shader set to pure white is not actually white unless I blast up the strength to at least 10. 



This is fine if something is just white, but if I want an image to show up, I cannot increase the strength without blasting out the image.  For example, I downloaded this smiley face and brought it into Blender, and then changed to an emitter.  How do I get it to look like the actual photo that I downloaded?



Help is much appreciated!!!
