When adding this many numbers together, it's rather easy to go way beyond 255. Blowing out the highlights is as easy as falling down. I have gone farther than what I've shown. One thing that I've done is add a lighting solution with the same nanometer definition method. Mixing colours is cool and all, but tossing in a light source is way coolier, especially when tinted. This is when I really started to blow things out way past white. The first thing that I thought was, "Hey, specular hightlights are inherent in the system." Well, not necessarily specular highlights, but reflection and intensity. But what if I don't want to blow things out too much? How do I reign it in or let it out just a little? This is the kind of scaling that has been running through my head. If you can believe it, I've actually read a few tutorials about fixing blown-out flesh tones in photographs. I remember thinking that it's a rather odd thing to fix if it's not too crazy. Is a little shine on the forehead really that bad? Does a little shine make a photograph so bad that it has to be fixed? Maybe for studio portraits, but I would largely say nay. The photograph that I remember in particular was outside in the park on a very sunny day. Of course our are going to see some white in the skin in certain areas - through the camera and/or with your own eyballs. How do we see the world with our own eyeballs as opposed to what makes a good photograph? Age old quandry, isn't it? Especially since retouching has become so prevelant in the past few years. Another phenomenon that I find interesting is the use of light absorbing make-up in conjunction with uber lighting. Understandable, yet some how ironic. Earlier today I was thinking about this while watching The Incedible Hulk. My eyes started to wander looking for reflections and highlights. I couldn't find a single thing that did not reflect a highlight of some sort. All it took was one window with closed blinds and closed curtains for everything to reflect highlights. Either daylight really is that strong (closed curtains and blinds) or such highlights are extremely prevelant. I have thought about this before with respect to shiny fleshies. Back then, I started to really look at foreheads. Unless the lighting is extremely dim, I see shiny foreheads to varying degrees. In the world of 3d rendering, I've always found it odd that specular highlights are a totally seperate attribute. To me, specular is just a reflection hack. Not just that, but how they were largely built to work with light objects only. This makes absolutely no sense to me. But it's what we do for speed reasons. When you get into photometrics and real reflections, render times seriously increase. So it's easy for me to get massively blown highlights with what I've been playing with. Do I fix it with a hack? Or do I adjust how I'm using the system? Do I go with what I observe around me, or do I go with what is considered 'good rendering' by the majority? And around and around we go. Loading...
