T-Grain technology - name for Kodaks film emulsion technology used in all Kodak APS films. Uniquely shaped grains that align better than conventional silver crystals absorb and transmitting light more effectively to produce sharper images.
In some color films where tabular-grain (T-grain) emulsions are used, high speed and increased sharpness are combined.
In the 1980s Eastman Kodak invented the T-Grain, a synthetically manufactured silver halide grain that had a larger, flat surface area and allowed for greater light sensitivity in a smaller, thinner grain.
A lot of pros use Kodachrome 200 pushed. I haven't tried Fuji Provia 400 but I don't think it is a lot better than the T-grain Kodak Elite 400, which I tried in 1993 and found wanting. I recommend using ISO 400 negative film.
In fact, Kodachrome 25 and Velvia are considered the two finest-grain transparency films on the market. So, why would your editor complain about grain in a Provia or Velvia photograph? Processing variables may be the culprit.
