When I'm printing my settings are the f/8 for 9secs on Ilford MG IV RC DELUXE SATIN FINISH PAPER with a MG Filter #3, after test stripping ofc, and it was the same for a second print from a frame of the same set of negatives. Will the settings be the same too on another frame from the same set...

Hi everyone! I am trying to edit some of my photos to make them big enough to have framed and put on my wall. But they are low resolution and I am not trained enough to know how to change them. Can someone please please help?? Thank you!!
