Re: Agar-agar

What is the best gelatin to use?
I see that fish gelatin is more transparent than bovine, wonder if that helps in the final efficiency, or refractive index modulation. Anyone know which one gives the highest index modulation?

fixing with strong whitelight

What is the logic behind fixing with strong white light, doesn't it expose the entire plate?
Which method is better, chemical or white light?
