What's wrong with the photo of cos? That is, colored ..

Actually, you don't know upstairs ... Cosmetic contact lenses usually don't show much color, depending on the photography technology and camera. At present, color matching generally adopts color scale color balance and highlight shadow, and some people directly paint layers, add various materials to eyes, etc ... In fact, if you want to use only color balance, it is good to look at it with the naked eye. After all, cosmetic contact lenses are opaque ... the effect of opening the layer can refer to my space default album "Yalian III".
