Order of operations when making a print from setting your easel blades to your desired print size to inserting your FINAL print in the developer.
What is 1. set your easel blades to your desired print size (keeping in mind your paper size, and the aspect ratio of the film) 2. insert your clean negative into the negative carrier, emulsion side down and facing away from you 3. turn the focus light on on your timer and adjust the focus until you see the grain in your grain focuser. 4. adjust the height of the enlarger head to fit to your easel blades, re-focus, repeat as necessary, and/or adjust your easel blades to crop your image 5. make a test strip, recommendation f/11 at 2-3 sec 6. determine the accurate density / time of your exposure, and possibly (if you have a good enough sample) determine if you need a filter--if so, make a new test strip 7. make a test print at the exposure 8. if you haven't done so already, determine if you need a filter, if so make a new test strip, and new test print 9. determine where you need to burn and dodge, and estimate how long, and / or make test strips to determine how long in each section 10. make a new print burning and dodging and / or with the filter 11. look at that print, determine if there are any more areas that need burning and/or dodging 12. if it's perfect, take notes on what you did and/or consider making an extra print or two 13. if it needs changes, make the changes, then insert your FINAL print in the developer.
