# How to make mesh lights brighter without washing out in the render? [duplicate]

Sometimes to get a mesh light to illuminate a scene fully I need to crank the emission value way up, however this causes the object itself to be washed out in the render. Is there any way to keep this from happening?

• Can I see an image of this so called washed out render? – iKlsR Dec 9 '15 at 23:53

• @Gonzou I searched multiple ways to try to find this question already (I was wanting to link to something explaining this in a BA post) before posting and couldn't find anything. I had totally forgot answering that one! SE needs a better search engine. – PGmath Dec 10 '15 at 1:11

You can do this by using the Is Camera Ray output of a Light Path node to dim the emission strength (or even use a different shader) for the camera. The Is Camera Ray will output a 1 if the ray is coming from the camera (see here for an explanation of ray tracing) and a 0 otherwise.
