How to Set Camera View using gluLookAt() function?

I have used glOrtho(500, 600, 600, 700, -100, 100) projection with this i want to use camera view settings with gluLookAt() method what should be the parameters for gluLookAt function on this projection…

They are not directly related. The gluLookAt should be used with the view-model matrix not the projection matrix.
