Different lenses change the look of your portraits a lot.

  • Shorter focal lengths will render the parts of your image that are closer bigger than parts that are further away. So if you choose for example 35mm, you will realize that the front arm of our model Anny looks bigger relative to her head than in the 85mm shot.
  • If you keep the size of your subject equal, longer focal lengths will blur the background more, creating a different bokeh than shorter focal lengths would.

ISO is actually a pretty weird name for the “gain”. It is short for International Standards Organisation*, and there are thousands of ISO standards flying around in the tech world. That the photography world decided to use the name of the organisation that standardized the gain  instead of using the term “gain” itself is beyond confusing.

A Quick Summary

To better understand what ISO really is, let’s recap exposure. If you are new to this site, I recommend starting here. For everyone else, here is a quick  roundup of what you learned so far, looking at this 20sec video.

The light of your scene that can be brighter or darker, passes through the aperture and once the shutter opens, the sensor is being exposed to that light.

When the shutter closes after a certain time (exposure time = shutter speed), the process of exposure has ended.
