Camera Basics: Aperture, Shutter Speed and ISO

So at times this blog can get a little bit complicated, Here is a little video in the hopes to bring those of you who aren’t so sure about the manual modes of your camera up to speed. These are concepts which took me quite a while to grasp so this video may take a couple viewings, I’ve also included a lot of resource materials and examples in the description which I’ll also include in this post. A huge thanks goes to my friend Matthew Audino of Audi Productions for filming and putting together this video. So here we go.

Stanford does a far better rendition than my kebab stick model for depth of field
Try changing the first three variables (F number is aperture) and looking at the depth of field, which is the portion of the photograph which will be in focus.

To remember the F stops, start with 1.0 and 1.4, double 1.0 to make the next stop, 2, then double 1.4 to make the one after that, 2.8. And so on. Remember it’s a fractions smaller number= Brighter= Shallow depth of field

The Shutter Speeds start at one second and with some rounding double and halve from there, most cameras range between 30 seconds down to 1/8000th of a second.

ISO starts on most cameras at 100, but sometimes can go down to 50. It simply doubles from there. ISO is generally used to compensate when you need a quicker shutter speed to freeze motion or a smaller aperture for more depth of field, yet keep the same brightness through upping the ISO. The trick is to use the lowest acceptable ISO for the aperture and shutter speed you desire.

The extremes of each of these:

Large Aperture (f2.8 and below):
Small Aperture: (Making a generalization that most landscape photos are shot on small apertures, however it’s usually the case)

Slow Shutter:…
Fast Shutter:…

Slow ISO: The majority of studio and landscape shots when sharpness is very important
Fast ISO (Larger numbers) :
