MODULE 1 ROADMAP
The short version
Five real situations, from a phone on a hike to a view camera on a tripod, worked through the way I would talk you through them: what I see, what I decide, what I do and why.
Scenario 1: Phone or camera for a hiking trip
What I see. A week of walking in the Scottish Highlands, or the Blue Mountains, or Yosemite: big landscapes in good light, misty mornings, dim pub or lodge interiors and distant deer. The walker has a phone and a small mirrorless camera with a 1.5× APS-C sensor and an 18–55mm zoom.
What I decide. Take both and give each a job. The phone does the wide, quick, everyday shots. The camera handles anything distant, dim or moving.
What I do. Check what the zoom gives: on this camera it frames like roughly 27mm to 83mm on full frame, so the long end brings a distant deer much closer than a phone’s digital zoom. Pack two charged batteries.
Why. The bigger sensor catches more light, so dim and distant frames hold together. The phone saves weight for everything else.
Scenario 2: Borrowing a portrait lens
What I see. A student with a Canon APS-C camera is offered an 85mm lens, “the classic portrait lens”.
What I decide. 85mm is the classic on full frame. On this camera (about 1.6×) it frames like about 136mm: a long view that needs a lot of room.
What I do. In a small living room, use the 50mm lens he already owns instead; on his camera it frames like about 80mm, close to the classic look.
Why. A smaller sensor changes the framing, not the lens. Choose the lens for the room.
Scenario 3: The dark church and the bright screen
What I see. A visitor with a second-hand DSLR in a dim church in Rome. Through the optical viewfinder the nave looks fine; on the screen the photos look fine. At home, every frame is dark.
What I decide. The optical viewfinder shows the scene, not the exposure, and the last owner left the screen on maximum brightness, which flatters dark pictures.
What I do. Set screen brightness to standard, turn on the histogram in playback (Module 12), use live view in very dim places, and fix the date and time zone too.
Why. With an optical viewfinder you check exposure after the shot. Once you know that, it is easy.
Scenario 4: Medium format for a landscape commission
What I see. A photographer hires a medium-format digital camera with a 44 × 33 mm sensor for a landscape print job. Her usual camera is full frame.
What I decide. The bigger sensor records a wider slice with the same focal length, about 0.79× crop. Her favourite 35mm full-frame view needs roughly a 45mm lens on this camera.
What I do. Choose lenses made for the medium-format mount (they throw a bigger image circle), work from a tripod, and allow extra card space and battery, because the files are large.
Why. Bigger format, same habits: careful framing, steady support, generous storage.
Scenario 5: A view camera on a city street
What I see. An architecture student borrows a 4 × 5 inch view camera to photograph a tall building without the walls appearing to lean.
What I decide. A view camera can raise its front panel, called a shift or rise movement, which takes in the top of the building while the camera back stays upright, keeping the verticals straight.
What I do. Level the camera on a tripod, raise the front standard until the roofline fits, focus on the ground glass under a dark cloth, then load one sheet of film (or fit a digital back) and make a single careful exposure.
Why. Large format is slow on purpose. Each sheet costs money, so you think first and shoot once.
Troubleshooting
| Problem | Likely cause | Fix |
|---|---|---|
| Viewfinder writing looks blurry, photos are sharp | Dioptre set for someone else’s eyes | Adjust the dioptre control until the writing is crisp |
| Screen goes black when you lift the camera | The eye sensor has switched to the viewfinder | Normal; change the display setting if you prefer |
| Shutter button does nothing | No focus found, no card, or lens not locked | Half-press on a contrasty edge, check the card, refit the lens until it clicks |
| Battery flat by lunchtime | Screen and viewfinder on all day, plus wireless features | Carry a spare and turn off wireless features you are not using |
| Photo times are hours out | Wrong time zone | Set date, time and zone on arrival |
| Lens error message | Dirty contacts or lens not seated | Switch off, wipe the contacts with a clean dry cloth, refit |
Go deeper
The maths behind the scenarios. Equivalent focal length = focal length × crop factor: 18 × 1.5 = 27mm and 55 × 1.5 = 82.5mm; 85 × 1.6 = 136mm; 50 × 1.6 = 80mm. Going the other way, 35 ÷ 0.79 ≈ 44mm, so a 45mm medium-format lens gives about the 35mm full-frame view. A view camera’s rise works because its lenses throw an image circle much larger than the film, leaving room to slide the film’s window around inside it.
Finn tip: Before any trip, write your crop factor and your lenses’ equivalents on tape inside your camera bag. It is a tiny job that pays you back every time the light is rushing.
Key takeaways
- Match the camera to the job: phones for wide and quick, bigger sensors for distant, dim or moving subjects.
- Use the crop factor to compare lenses before you borrow or buy.
- Bigger formats reward slow, careful work on a tripod; view cameras can correct leaning buildings.
