168/365 ~ Aperture Study: f/3.2

by Heidi Egerman June. 17, 2018 362 views

Since I'm spending quite a lot of time on the wider side of the aperture setting (which gives me shallow depth of field), I thought I would mention that the focal length of the lens and the camera to subject matter distance will also affect the depth of field. As I mentioned before, my focal length is 50mm since I'm using a 50mm prime lens. Therefore moving closer or further away will affect the DOF. I have this affinity to macro and close-up photography so I have to force myself to step back now and again.

You can see this distance difference in images 5 & 6 below. Every day I've been learning something new. If you were not already aware of this, give it a try and find out for yourself. Since I'm an amateur I was not aware of this, but now I can see how I can use this knowledge in the future.

When you focus on your subject, the further your subject is from the focal plan (sensor) of your camera the more depth of field you will have using the same f/stop and lens. See images below.

Beautiful 
Wonderful study and revelations! 
Very informative! 
Nothing like personal trial & error for truly internalizing learning! 
Thank You!

Interesting read and beautiful shots Heidi. I've been running into problems with my macro lens and wasn't sure if it was the lens or me. Finally took it to the local camera store and they were nice enough to let me know that it is the operator and not the lens who's got issues. The thing that stuck with me is that macro lenses in contrast to the prime lenses or zooms really need to be placed on a tripod if you are doing close ups because the minuscule movement cause the whole pic to be out of focus. Also closing the aperture makes a ton of difference.

Thanks Camellia,
I often shoot on a tripod because I've noticed how any type of movement can cause the image to be out of focus. Macro especially, but even close ups. I envy those who can shoot without a tripod and get a tack sharp focus. And I am learning this about the aperture. I've a tendency to shoot quite wide open and know that I can still get some depth of field without being so wide. I'm anxious to the smaller apertures in the next few days. grinning
