FORMULARY TFX-2 HIGH DEFINITION DEVELOPER is an updated proprietary modification of the popular FX-2 developer. A number of small modifications have been made to gain better performance with the most modern films including the T-grain films. TFX-2 offers an extremely high degree of sharpness, which is at least as great as the Beutler developer, although somewhat less than FX-1. However, gradation with TFX-2 is much more pleasing than with either Beutler or FX-1. TFX-2 offers a speed increase between one half and one full stop and has an exceptional resistance to streaking. This is one of the most versatile film developers on the market today. By varying dilution, agitation and development time an extremely wide variety of contrast effects can easily be obtained. The stock solution will make up to 10 liters depending upon the dilution used, and has a shelf life of 1 year in a full well capped bottle. The working solution is a one shot developer with a life of a few hours.
