Lens and Camera Terms for Image Prompts
Use focal length, aperture and shot vocabulary to get photographic images on purpose
A taste of a lesson
I added '85mm, f/1.4, bokeh' to a street scene and the whole street went blurry. Why?
Those terms are strongly linked in training data to tight portraits with a melted background, so the model pushed your scene toward that look. On a real camera, 85mm at f/1.4 would blur a busy street too, unless the subject is far away. If you want the street readable, try '35mm, f/8, the whole street in sharp focus, a cyclist in the middle ground'. Try both versions with the same seed. Which one tells the story of the place better?
Written by the teacher as an example. In your lesson the tutor answers your own questions, and like any AI it can be wrong.
What you will be able to do
- Choose focal lengths that match the perspective you want
- Control background blur with aperture and plain language together
- Name classic lighting setups and predict their effect
- Spot camera terms that conflict or that a model ignores
Lesson plan
- 1 Focal length and perspective Predict how wide and long focal lengths change faces, scale and backgrounds. Start
- 2 Aperture and depth of field Control what is sharp and what is blurred in the frame. Start
- 3 Shutter, motion and time Use motion freeze and blur words to show movement. Start
- 4 Classic lighting setups Name and request portrait and product lighting setups precisely. Start
- 5 Film looks and colour Add colour and grain character without leaning on brand names. Start
- 6 Putting it together without conflicts Write a full photographic prompt where every term agrees. Start

About this tutor
For people who already write decent image prompts and want photographic realism that looks deliberate. You will learn what real camera terms mean (focal length, aperture, depth of field, shutter effects, film stock, lighting setups) and how image models interpret them as visual cues rather than physics. We compare a portrait at wide and long focal lengths, shallow and deep focus, and different lighting setups, so you can see which terms change the result and which are ignored. Useful for marketers, designers and hobbyists who want believable photographs without a camera, and for photographers learning how their vocabulary translates.

I teach people how to make images with AI that look intended rather than accidental. My background is in photography and retouching, so I approach image models the way I approach a shoot: decide what the picture is for, plan the subject, the framing and the light, then fix what goes wrong. I like short exercises where you write a...
