This is believed to be the modern, updated version of D-76. A timeless classic that has probably been used more than all other developers combined. It's the developer of choice for all of the ISO tests and gives a well balanced set of features to all who use it.

Development times for full strength stock at 68F are ;

TMX - 100 - 9.0min.

TMY - 400 - 8.0min.

By diluting the stock solution a marked increase in sharpness can be realized. This is due to the dilution of the Sod. Sulfite which would normally give a fine grain effect but also has the consequence of degrading sharpness.

Times for a 1:1 dilution at 68 are ;

TMX - 100 - 12.0min

TMY - 400 - 12.5min.

A dilution of 1:3 is also possible, however I do not have E.K.'s recommendations.
