What are the “priorities”? Before the digital era, analog SLRs were divided into two categories: shutter priority or aperture priority. What kind of influence can have choosing between the first or the latter option? And why is it so important with the Lubitel 166+?
Let’s start from defining what are the two priorities. Few episodes ago, we spoke about Aperture and Shutter Speed; we can give priority to the first or the latter, in terms of keeping the first fixed and the latter changing (or vice versa).
- Shutter Priority: the shutter speed is fixed and the aperture changes, according to ambient light and reflected light, in order to give you a perfectly exposed image.
- Aperture Priority: aperture fixed in one position and the shutter speed can change, in order to have a correct exposition of the frame.
Nowadays, modern digital cameras have both Aperture and Shutter Speed priorities. With ancient 35mm SLRs this was impossible, so photographers were used to choose between the one or the other; this choice was not random, because there’s a specific stylistic and composition reason to choose between them.
In that period photographers were divided into two categories:
- The ones who used Canon cameras (Shutter Priority cameras);
- The ones who used Minolta, Nikon, Pentax and Minolta (for example), which were Aperture Priority cameras.
No one won, between the two styles. In 1977 the Minolta XD-11 was released in the market, which was the first camera able to use both the modes (let’s call it “dual mode”), letting the user to choose between Aperture or Shutter Speed priority.
Good news: The Lubitel 166+ is able to shoot both with aperture and shutter priority!
In the next two episodes we will see HOW…
Disclaimer: We spoke about philosophy, history (ancestors and birth of the project of the Lubitel 166+),tech specs. Inside all the previous article I left some little, but very important, details that will let you easily interpretate the next ones. These articles are meant to be read in series, so don’t lose the opportunity to go and check the previous episodes.
