Let $X$ be a smooth degree $d$ ($d>5$) surface in $\mathbb{P}^3$. We now blow up $X$ at a point, embed it in some projective space, and and consider a projection of it into $\mathbb{P}^3$. The question is does this resulting surface have only ADE singularities? If not when is it the case? What is the degree of the final surface?
