Photography Tips | Understanding Aperture and F-Stop Numbers

Understanding aperture and f-stop numbers. Mother holding her baby's head, in a before and after comparison of the editing.

Understanding aperture and f-stop numbers…do you understand any of those terms?! If not, it’s okay. I”ll try to explain how they work in relation to this image!

Newborns grow so quickly so this is an angle that I love to capture for parents so they can remember how tiny their babies once were!

The focus here is on the whorl of hair at the top of the baby’s head so I used a very wide aperture: f/2. The wider the aperture (indicated by a smaller f-stop or f-ratio number), the more light is able to go inside the lens and reach the sensor. It also creates more separation from the area of focus with the rest of the image. Using a wide aperture (aka “stopping down”, “increasing depth of field”) allows me to blur everything else in the picture so that the eye is drawn to the hair.

I also noticed a bit of magenta in the “Before” image, so I adjusted it in Adobe Lightroom by sliding the tint slider towards the green end. That, plus brightening the exposure, resulted in the final image as seen on the right!
