Abstract
If T-grain Technology can be used to manufacture emulsions of astro nomical type, it will provide a better Detective Quantum Efficiency than any existing plate. As Dr. Millikan explains us, this increase in D.Q.E. can result in an increase in Signal to Noise ratio (i.e. increase in con trast or decrease in granularity) or in an increase of plate speed. As Kodak and we, their customers, don’t have a lot of money to spend for three or more new emulsions, we have now to choose for a new emulsion, which might be a harder one (more contrast), a finer one (better granula rity), or a faster one. Let us now examine these three possibilities:
