Hello, I'm coming back to B&W and i'll like to know if the agitation method from Kodak or Ilford will give more or less the same result with same film and chemicals? Since one used more agitation less often orthe other way around. Is there some advantages to agitate the first 30 seconds. Also, i read that pre wetting the film before development might help in the case of 120 films or it is old school. REgards!
