Lenses
You will use a variety of lenses to understand a range of focal lengths and maximum aperture.
Focal Length: Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point where light rays converge to form a sharp image of an object to the digital sensor or 35mm film at the focal plane in the camera.
The focal length of a lens, measured in millimeters, tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification.

Maximum Aperture: The limit to how wide a lens can be opened as shown on the camera lens.
a lens with a wider maximum aperture lets in more light. Lenses with lower f stop numbers (wide apertures) are know as FAST lenses. Larger apertures like f2.8 or even f1.8 are highly desirable because they let in more light and allow you to shoot in low light conditions without getting camera shake.

What does 1:3.5-5.6 mean?This indicates the maximum aperture of your lens, which is how wide it will go, and ultimately how much light it will allow in. When the number is lower, it allows more light in.
Sometimes you will see lenses which say 1:2.8. This means that the lens will allow a maximum aperture of f/2.8 throughout the whole zoom range. When there is a hyphan, such as 3.5-5.6, this means that the more you zoom, the narrower the aperture will go. When you’re at 18mm, you maximum aperture will be f/3.5, but as you zoom, this aperture will slowly narrow, until you reach 55mm, at which point it will only allow and aperture of f/5.6.
The reason the number is a ratio (1:), is because aperture is measured as a ratio.
You will take photos with each of the following lenses and post on your site:
All photos should be edited before posting! Crop, levels, color balance or convert to black and white with NON-DESTRUCTIVE techniques (adjustment layers).
Telephoto Lens 55-300 mm - 3 photos total:
1 sets of 3 photos where you progressively zoom in while standing in the same location.
Choose an area where you can see a far distance: down hallway, library, out a window...
Option:- include a person in middle ground: Create a portrait where you can see blur created in the background as you zoom in more on the face.
18-105 mm zoom - 3 photos
Set of 3 photos as you zoom in.
18-55 Kit lens
1 shot of building, 1 shot of person
35 mm or 50 mm Prime Lens-3 photos
With this FIXED lens, you will have to re-position yourself to take a photo instead of zooming in and out!
Take a variety of shots- portraits, take a shot in the spot where you took your telephoto shots, and try the bokeh
string lights experiment where you create blur in the background- also try using the shape lens covers to create bokeh in stars, hearts, etc.
85 mm Prime Lens- 3 photos - Often used as a portrait lens because of the shallow depth of field and ease in taking a portrait without having to get very close to the person which could make them uncomfortable.
20 mm 1: 1.8 (fixed) Wide Angle Lens- 3 photos - In a wide angle lens, the focal length is smaller which allows more of the scene being photographed to be included. Wide angle lenses are useful in architectural or interior photography where the photographer may not be able to move farther back from the scene to photograph it. (This can make a bathroom or swimming pool seem much larger than they are!)
Macro Lens-3 photos
Select a variety of tiny object or zoom in on the texture or details not usually seen/noticed on another object.
Another use is where the photographer wishes to emphasise the difference in size or distance between objects in the foreground and the background; nearby objects appear very large and objects at a moderate distance appear small and far away.
This exaggeration of relative size can be used to make foreground objects more prominent and striking, while capturing expansive backgrounds.
