Phone Cameras

Smartphone cameras are great at taking phots with the default setting, but sometimes we want to do other things, like taking a looooong photo with low light settings to do things like light painting.

Most modern Android phones will have a "Pro" mode or "Manual". iPhones have more limited controls (unless you download an app that give you manual control), but there's still much than can be done

Let’s start by understanding what it takes to expose an image correctly. This is crucial for shooting in manual mode. In photography, the exposure triangle represents how ISO, aperture, and shutter speed work together. You must find a balance between these three elements to expose an image correctly while keeping in mind how altering each element affects quality.

ISO is a setting on your camera that controls how sensitive the camera’s sensor is to light. Think of it like this:

Low ISO (like 100): The camera is less sensitive to light. This means you might need to let in more light by opening the lens wider or keeping the shutter open longer. The good news? Your pictures will look cleaner and clearer!
High ISO (like 1600 or more): The camera becomes more sensitive to light, which is great for low-light situations. You can take pictures faster or use a smaller lens opening. But, the downside is that your photos might look grainy or noisy, which can make them look less sharp.

So, if you want clear pictures in bright light, use a low ISO. If you’re in a dark place and need to capture more light quickly, go for a higher ISO, but be ready for some graininess!

Shutter Speed is how long the camera’s shutter stays open when you take a picture. It controls how much light hits the sensor:

Fast Shutter Speed: The shutter opens and closes quickly, letting in less light. This makes your photos sharper and can “freeze” action, so moving things look clear.
Slow Shutter Speed: The shutter stays open longer, allowing more light in. This can create a cool motion blur effect, making moving objects look smooth, but it can also make your photos brighter.

So, if you want sharp pictures of fast action, use a fast shutter speed. If you want to capture movement or need more light, go for a slower shutter speed!

Focus

Manual Focus: You can control the focus yourself. This lets you choose exactly what you want to be sharp in your photo.
Focus Peaking: Some cameras highlight the areas that are in focus with a color. This makes it easier to see what looks sharp.
Tap to Focus: You can tap on the screen to focus on a specific spot. This is quick and helps with moving subjects.
Depth of Field: The aperture affects how much of the scene is in focus. A wider aperture (like f/1.8) blurs the background, while a narrower one (like f/8) keeps more in focus.
Locking Focus: If you find a good focus point, you can lock it so the camera doesn’t change it if you move.
