I'm not sure this qualifies as an essay, being taken with a couple of cameras and three different rolls. What it does have it commonality in the subject: my pregnant wife.
I'm still struggling with the manual focus which makes me think I need glasses or, at the very least, a dioptric correction for the cameras.
The B&W ones were taken with an Asahi Pentax Spotmatic and a 50mm 1.4 Super Takumar. The roll used was Agfa 100 APX pushed to 400. The color was made with a Canon AE1 with 50 and 35 mm lenses, using Fuji Pro 400H and Portra 400.
All comments well received.
P.S: Please, if this does not qualify as an essay, feel free to remove the post... no hard feelings.
