Keep every thing very simple and basic ~ Use one film and one dev (HP5 and ID11 or Tri-x and ID11) a box of 5x7 and three dishes ~ small enlargements are nice to carry with you ~ do not worry about the enlarger or lens too much ~ print boarder-less ~ keep every thing clean ~ use multigrade paper without filter! (try 5 secs at F5.6) and get your film processing right ~ Try this ~ rate your 400asa film at 320 and develop stock for 7 minutes at 20 degrees ~ and the magic? expose all of your first film at 1/125 ~ F8.0 ~ you have nothing to loose and....I have taught this for 20 years and every time my students have had a big smile on their face!!
