<p>Hello everybody,</p>
<p>I am new here and totally lost regarding B&W ASA / EI / film development / printing - all in one.<br>
I don't develop myself negatives, but via a lab who I don't meet in person because my local photo-shop is the dispatcher of my films, because the lab is approx. 300 miles away. I had no issues with slide films so I trust them, but I need some help regarding B&W and how to explain to them what I really want.<br>
I intend to shoot following B&W films:<br>
ILFORD 3200 at EI 1600<br>
ILFORD HP5+ 400 at EI 800</p>
<p>So I did my own logical thinking<br>
3200 ASA film shooting at EI 3200 = 0 (standard)<br>
3200 ASA film shooting at EI 1600 = -1 (reduce grain)<br>
400 ASA film shooting at EI 800 = +1 (add grain)</p>
<p>Now without much knowledge but a lot of imagination, I desire or want to have following result: from a film with less grain I want more and from a film with more I want less. So can any of you explain it to me, please? I had in mind not to tell them (the lab) anything and have them develop and print it for me as "normal" e.g. Ilford 3200 at 3200 ASA, but what impact will it make on final result bearing in mind that I shoot it at EI 1600 / or will the result this way be what I want it to be, less grain? Or if I want EI 1600 (-1) result the film must be processed at 1600 ASA too? Because in my head if I shoot at EI 1600 and have it developed at 1600 ASA then it is a 0 (same standard), not a -1 or +1.</p>
<p>Thanks in advance.</p>
<p> </p>
