you have your test strip what are you looking for? You are looking to see which of the
timed sections gives you blacks that are really black without making the whites
look grey, with a good separation of the greys in-between. If the picture looks
grey overall with no defined blacks then the paper grade is too soft, meaning
lack of contrast. On the other hand if the blacks dominate the picture then the
grade of paper is to hard - too much contrast! If you need to change the grade
of paper you will need to make another test strip. It should be noted that test
strip evaluation is best carried out when they are dry as wet ones tend to hold
back some of the more subtle grey tones which may encourage you to pull or push
the expose time needed. While checking this you should also be ensuring that
the focus is accurate.
test strip is pin sharp with good clear highlights, defined shadows and the
right amount of contrast, you are ready to make a print.
