10:10 Photography – The Exposure Triangle

The three main pillars of exposure are Aperture, Shutter Speed and ISO. We’ve talked about the first two. Aperture and Shutter speed are physical mechanisms that allow you to control the light.

ISO measures the light gathering speed of film. Back in the old days old timey images were exposed for a long period of time using long shutter speeds. With digital cameras the sensor is …well… more sensitive so we can shoot at faster shutter speeds and increase light through ISO.

That means that when you take a picture there are three things that determine how light or how dark your image will be.

Aperture – (how large or how narrow the aperture is will impact how much light passes through the lens (effect – blurred backgrounds and depth of field)
Shutter Speed – (how fast or slow the shutter opens and closes – good for stopping or blurring action)
ISO – the amount of light allowed to hit your camera’s sensor

These three things together are referred to as the Exposure Triangle

For the most part we have been shooting with Auto ISO. ISO records light levels across the sensor and charges each pixel with electrons to amplify the signal. ISO is simply how much amplification is applied. So if we need more light, we can increase the amplification.

This amplification comes with a cost though. The higher the levels, the noiser the image. Take a look…

Shutter Speed
Aperture
ISO

That’s it! If you know these three, then you know how the fundamentals of photography work!

Why, When and How to increase or decrease the ISO…. – Let’s practice

Take picture with ISO at lowest to auto setting.

Enduring Questions to ponder?

What happened with our shutter speeds at low ISO settings?
Why would a tripod be useful at low ISO settings?
Why were the images at high ISO so bright?
What changes did you notice with the shutter speed at different settings? Why would the camera change the shutter?
Nighttime photography, why would higher ISO be useful
If you are photographing a subject that is moving or the light is changing what ISO setting would make your life easier?
Can you change the max ISO setting in your camera?

10:50 Morning Break (10 minutes)

11:00 Personal Logo Showcase

This morning we are going to take a look at your logos. Your task is to put a checkmark next to your two favorite personalized logos from your classmates.

After some crowdsourcing, you may, as the designer, choose to agree with the feedback you received or go against the grain and continue with your own choice.

Your next task is:

Select two of your logos
Redraw your logos on 1 sheet of paper (incorporate any feedback if you received some)
Go to Illustrator and create two artboards (one logo per artboard) to create digital versions of your logos.
Next week we will animate your logo – so my pro-tip is think about how you might want to animate your logo and divide up anything that needs to be individually animated on separate layers.
