Can't decrease the brightness of the transparent shader effect I'm trying to make a transparent plane in blender 2.8 that works in cycles. I want to reach the same effect that I have when I set up a background image with the transparency enabled. Below you can see how I have configured the shaders :



Instead,below you can see how it should look like :



mine is too bright. I tried to change the strenght value,but I don't get the desired effect. What's wrong here ? thanks.
The following node setup still uses an emission shader, but ensures that it only affects the camera. The math node allows to control the transparency of the image. If you'd like to adjust the brightness you can add a Bright / Contrast node between the texture node and the emission shader node (Add > Color > Bright / Contrast).
