How do I know how much room I have to play with before a subject goes out of focus? It seems to change with f stop, how close I am to the subject(s), and the focal length I am using.

Shallowdepth of field

Some rules-of-thumb: DOF is not split down the middle; it extends about 1/3 back towards the camera and 2/3 behind the distance focused upon. Portraiture likely is best if DOF is shallow; use larger lens openings Landscapes likely best if DOF is expanded; use tiny lens openings. Best if the focus distance and the aperture used match the hyperfocal distance. Hyperfocal distance: Maximizes DOF – all distances acceptably sharp from infinity ∞ to half the distance focused upon. Use tables / charts to find hyperfocal distance. A math formula that will calculate: Focal length X 3.3 ÷ f/number = Hyperfocal Distance in feet. Example: 50mm lens mounted and set to f/16 Hyperfocal Distance = 50 X 3.3 ÷ 16 = 10 feet. Set focus to 10 feet and aperture to f/16 then DOF extends from 5 feet to infinity ∞ .

Focal length of the lens – shorter more DOF – longer less DOF 1. f/# - Lower aperture number (larger opening) less DOF 2. f/# - Higher aperture numbers (smaller opening) more DOF 3. Subject distance – The further the subject the more DOF 4. Viewing distance – The closer the displayed image is to the observer the less DOF 5. Acceptance of what is sharp is a subjective decision 6. DOF charts and calculators abound, but likely we can’t consult during the shoot. Additionally, the DOF viewfinder preview falls short; we must fall back on experience and instinct.

For portraits, I generally try to pick lower f-stop like between (1.8-6f). For more general use like taking pictures of animals I usually pick between (6f-10f).

I am fairly new to photography and I have read many "beginners guides" and watched youtube tutorials. One thing that remains elusive to me is how to properly pick what f-stop to use.

I understand the concept that I am basically focusing on a "slice" of space in front of me and when I lower the f-stop, this slice of space becomes narrower. I can't figure it out and I end up getting disappointed when I view the pictures on a large screen.

The issue I primarily run into is that when I take a picture with a lower f-stop, it looks great in my viewfinder. However when I go home to load it on a larger screen, I find that a lot of elements I am trying to capture is actually out of focus.

Depth-of-field (DOF) We focus our camera to obtain a sharp image of an object at a specific distance. We know from practical experience that objects before and behind the distance focused upon will appear sharp. This span of acceptable sharpness is what we term depth-of-field (DOF).
