I am 60+ and a lover of image making. First mainly digital, now analogue for years. Have your own dola and a large collection of cameras. In addition to the Rolleiflex, I photograph with the Leica IIIF with Elmar 3.5 5cm. But also shot a roll with the Ahasiflex. small film.
To understand the quality of negatives and understand the influences on the quality of a negative image, I am now delving into Sensitometry, Characteristic curve (SD), step wedge, but also Ansel Adams and his Zone System. Beautiful hobby with many challenges and possibilities. For now I'll stick to black and white photography and development.
