I have seen pouncing gel talked about, but I have never really seen anyone talk about why they think it does not work. I have only seen people describe why they think it works, or people simply say it does not work. My thoughts are this, please give me your ideas.
When you poke a hole in something, what you are really doing is creating a slit and then pushing all the material to the outside of the of the needle. You are not actually punching out any material, like you would with a dermal punch. Because of this, you are actually creating a small hole and around that hole, you have simply displaced material that was supposed to be in that hole. Poke a hole in some gel, close your eyes and feel around for it, you are certain to find it. When you are talking about gel, that extra material equals a slightly ticker spot, or, a darker spot. These dark spots adsorb more light and end up getting hotter than all the gel around it. In pouncing gel, are we actually just creating hundreds of points of failure, that were not there before?
People usually say that these holes help some of the heat escape from between the gel and the lens. Unless you went way, way over board, I can't imagine ever being able to poke enough holes to get any sort of airflow to remove that hot air. Also, in general, our instruments are pointed down, maybe instead we should be drilling holes in our lenses so that the heat can travel up and away from the gel.
What I'm wondering is: is pouncing gel actually doing far more harm than help?
