<p>Chris<br> I'm not able to print; I'm scanning negatives, so I guess this could also be a factor.<br> As regards agitation, my routine is ten seconds in every minute.<br> This morning I developed a roll of HP5 for 11 minutes, in line with Tetenal's recommendation. My first impression looking at the negatives is that they look markedly different to the ones I've been producing, with sharper definition, but I lack sufficient experience to be able to read negatives. I'll have to wait until I've scanned them later today.<br> Rex</p>

<p>Robert, this is a most helpful response, thank you.<br> Please excuse my ignorance here. When you say expose on EI 200-250, does this mean set the film speed on the camera to 200-250? Then, with a dilution of 1+50, how long would I develop for?<br> In line with what you say, I certainly seem to be getting better results with an ISO 100 film.<br> Rex</p>

<p>I started developing films recently and, so far, have used Tetenal Paranol S. I've read that Paranol S is based on the formula of Rodinal, and so employed developing times for Rodinal when no time for Paranol S was given.<br> I've been producing some pretty grim results - flat, grey, murky - with Ilford HP5 film and, in an attempt to get to the root of the problem, checked developing times and found an apparent contradiction. Ilford recommends 6 minutes for Rodinal, and Tetenal 11 minutes for HP5.<br> I use 1+25 dilution at 20 degrees.<br> Is Paranol S fundamentally the same as Rodinal or not?<br> Thank you<br> Rex</p>
