The >more you agitate the more grain you'll get. > >Jiri D. As you said, the more you agitate the more grain you'll get. But it is not only a question of how long or how often you agitate, but also how you agitate. Kodaks own instructions are interesting. For T-Max developer they say "agitate vigorously", and for Xtol they say "agitate gently". They have a reason for using different terminology. Try the following: lift the tank -gently- a couple of inches, then - -gently- turn it round its own axis, wait a second or two to let the liquid settle in its new position, then -gently- turn it back round, (wait a second or two and repeat turning as you wish), and then -gently- set the tank down. It makes a difference to the grain if you do it this way or if you shake the tank like a bar tender. - -- christer almqvist eichenstrasse 57, d-20255 hamburg, fon +49-40-407111 fax +49-40-4908440 14 rue de la hauteur, f-50590 regnéville-sur-mer, fon+fax +33-233 45 35 58
