photography concepts
High Resolution
Resolution refers to the amount of detail in an image. A higher resolution photo means more more detail. The resolution of a picture is determined by its number of pixels; the higher the number of pixels, the sharper the image will be. High resolution photos are excellent for printing, but take too long to load on the internet.
low resolution
Resolution refers to the amount of detail in an image. A lower resolution photo has less detail. The resolution of a picture is determined by its number of pixels; the higher the number of pixels, the sharper the image will be. Low resolution photos have small file sizes and are perfect for webpages as they are quick to load.
High Contrast
A high contrast photograph has intentionally contrasting elements. This is common in black-and-white photography, where pictures will have few grey middle tones, but lots of strong blacks and whites. In colour photography, a bright element will be cast against contrasting or darker colours. Simply put, in a high contrast photo, the range from dark to light is very wide.
Low contrast
In a low contrast photograph, all the colours and and tones in the scene are similar in appearance. Simply put, in a low contrast photo, the range from dark to light is very small.
exposure
The exposure of a photograph determines how light or dark an image will appear after it's been captured by your camera. This is determined by the amount of light the camera sensor captured when the photo was taken. Too much light creates a washed out photo (overexposed) and too little creates a dark photo (underexposed). Aperture, Shutter speed and ISO speed directly affect the exposure of a photograph.
depth of field
Depth of field is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. A shallow depth of field blurs background and foreground details, removing distractions and directing viewers to the focal point in a picture.

Portrait questions
Recall:
There are four types of portraits:
A smaller f-stop number (larger aperture) will create a shallower depth of field. Conversely, a larger f-stop number (smaller aperture) will create a deeper depth of field. In any portrait, having a shallower depth of field will create more emphasis for the subject, as the background will be out of focus. A deeper depth of field would put emphasis on the portrait as a whole. The photo is lit from behind and slightly to the right of the camera, as you can see more shadows on the left side of the subject.
Analyze
Julia Margaret Cameron's "The Passing of Arthur" was a formal portrait. The image doesn't have a lot of composition in it; it's just a photograph of the subject on a black background. The depth of field must be shallow, as only the man is visible/in focus. The image has a regular level of contrast; you can see the shadows in darker parts of the photo, and the lights on the man's skin and parts of the armor where the light is bouncing off.
Synthesize
Formal and candid photographs are opposites. My formal portraits were shot on a set, and the poses, lighting and background were all planned. My informal (candid shots) captured people going about their everyday lives and activities naturally. My candid shots are often lower quality; they are usually over/underexposed, blurry, or poorly focused. In order to make my candid shots better, I need to better understand photography elements like aperture, shutter speed and exposure so I can change my settings on the fly and take the perfect shot.
Evaluate
I believe candid portraits are the most successful form of portrait to shoot. Once you get people comfortable enough in front of the camera, the pictures turn out much better and are more full of life. Each picture feels more personal and has its own story. The portraits end up feeling a lot more realistic and natural, and are easier for people who can't come up with a pose in a formal portait.

- Formal portraits
- Candid protraits
- Environmental portraits
- Self portraits
