In my experience, TD-3 does everything Photographers Formulary promises. I've shot TP in my Hasselblad at ISO 50 and found the results with TD-3 to be excellent. The shadow detail is there and it gives beautiful tonality. I used the Formulary's "acutance" method of developing with agitation every 3 minutes. The sharpness and absence of grain are pretty amazing.(posted 8914 days ago)
