Photomicrography Astronomical Photography The low contrast of most microscopic subjects often requires The extended red sensitivity of Technical Pan Films makes a contrast-enhancing film-and-developer combination and them especially suited to solar photography at the H-alpha (with stained specimens) a contrast-enhancing filter. For line (656 nm), and their reasonably uniform spectral routine photomicrography of H and E-stained tissue, try a sensitivity over the visible region of the spect
