You can see in the photos below how when at the same aperture the photo with the wider focal length has less depth of field.

Understanding DOF will allow you to add interest in your photos. If you want your subject to really pop you need to know how to create a shallow DOF. If you want your whole image in focus, like in landscape photography, you will need to create a deeper DOF.

I hope after reading this you have a better understanding of depth of field. Now go get your camera out and experiment with DOF.

The FS70-4K4 has an added built-in IR LED light source to stimulate NVG for training at nighttime with IR transmission optimized at 740nm. It allows for full individual control of both the visual and IR light intensity, making sure the projector is tuned exactly to the trainee’s scenery needs. The dual iris built into the projector ensure improved contrast and deeper black levels for the most realistic image reproduction.

Aperture, focal length, and distance from your subject. Using a combination of those 3 things you can create exactly what you need.

The FS70-4K4, powered by Barco Pulse image processing, is an addition to the flagship F70 laser-phosphor series with native WQXGA and up to 4K (3,840 x 2,400) resolution. This version comes with an added built-in IR LED light source to stimulate NVG for training at nighttime. It comes with improved performance for fast moving content, as well as improved color-to-white ratio, intended for high-demanding applications. Designed specifically for the simulation market’s tough requirements it is robust and reliable, with an outstanding image quality.

The distance that is sharp around your focus point. Shallow DOF means not much of your image other than your subject is sharp. Deep DOF means a lot of your image other than your subject is sharp.

In the photos below you can see how the focal plane affects how much of the photo is in focus. The first photo all the toys are in focus because they are on the same focal plane.

As you can see from the example above the 200mm lens really compressed DOF. Even though these images were both shot at the exact same place this lens makes the subject and background seem more pushed together.

The below photos were taken with the same settings and same focal length. The only difference is I moved the stool closer to the plant in the second photo.

I’m not really sure what James (the above commenter) is talking about as he really doesn’t elaborate what he takes issues with in regards to this article.

If you are struggling to fit everything in the frame is it because you have crop sensor? See here: Everything you Need to Know About Crop Sensor vs Full Frame

In each of the photos below you can see that the focus is on the bunny but how blurry the background is (DOF) changes drastically depending on the aperture.

In fact, if you are shooting with your kit lens this is a great trick to give you a more narrow depth of field when you feel restricted by how wide your aperture can go.

Designed for the motion platform's rapid and sudden movements, it is the perfect choice for any type of applications that need a robust visual system that last over time and can be operated 24/7. With a lifetime of up to 60,000 hours* coupled with long service intervals, the F70-series is one of the most durable projectors on the market and make sure the training time is maximized.

The next photo only the wolf is in focus. The other toys are on different focal planes. They have been moved to a different focal plane therefor they are not blurry. You can see this more clearly with the turtle, half of the turtle in in focus while the other half is on a different plane.

The only thing that confuses me is the area where you talk about sensor sizes where it seems that you may be contradicting your own argument by stating:

To be able to explain depth of field we have to start with defining certain terms. Then I will get into describing some things that affect depth of field.

When you are shooting more wide open (smaller aperture number) less of the photos will be in focus. Then you will have a narrow depth of field where the background is blurred.

Notice in these next few photos how the subject is in focus but the majority of the rest of the photo is not sharp. This is showing narrow or a shallow depth of field.

If you are anything like me, understanding depth of field (DOF) was one of the biggest hurdles you had to overcome when learning the technical aspects of photography and shooting in manual mode. I would read explanations online, see links to calculators, hear it described as “shallow” or “deep” and couldn’t make sense of it all.

Hi! wonderful article today. Is there any chance you could post the same pics of your “studly” husband with the 50 mm and 85 mm with the same camera settings, to see the difference? Can you tell I’m an an amateur? LOL

Hey Adam! Thanks for the comment. To clarify sensor size does affect depth of field, but since most people use one camera consistently (and thus one sensor size) I didn’t want to go into too much detail about how changing sensor size affects DOF. That subject could be a whole article on its own but since most readers of this particular blog probably don’t switch between full frame and crop, I felt it was the least important factor to discuss. Hope that makes more sense! Thanks for asking!

STIHL FS 70 R review

The FS70-4K4’s powerful and improved Motion Smear Reduction Processing (SRP) is optimized to remove the typical challenges occurring when viewing fast-moving content, e.g. when an aircraft is rolling, pitching, or banking. Combined with an improved color-to-white ratio, the user will experience increased brightness in colors, better color performance across moving images and deeper black levels for an impeccable reproduction of scenes. The SRP feature will also have a positive impact on lifetime.

I know a lot of people who initially struggle with getting a grasp on aperture and depth of field especially when starting and and you have laid out it nicely in this article.

Even though every photograph is two-dimensional, it portrays a three-dimensional world. The distance between the camera and the subject and the distance behind the subject to the “end” of the photo is the “depth” of the photo. The amount of depth that is in focus is the depth of field.

One day it just clicked. I’m not sure where or when, but I have a much better grasp on it now. I love using that knowledge to positively impact my own personal art as well as the art I create for my clients.

Sensor Size: “I believe this has the least impact on depth of field” and then you state “Changes in DOF depend on whether you use a crop or full frame;”

DOF is a range of distances on either side of the focal plane that are “acceptably sharp.” (“Acceptably sharp” is where the confusion begins.) Another way to state this would be, the area behind and in front of your focus point that is in focus as well.

Focal length can affect the depth of field as well since the longer you focal length the more narrow your depth of field is.
