1. Noise realism at high ISO
- Users debated whether the simulator’s noise matches real cameras.
- ChrisMarshallNY: “That does a fairly good job.”
- arghwhat: “I would still say that it's way too noisy.”
- einr: “Noise depends a lot on the actual amount of light hitting the sensor per unit of time… the simulation here exaggerates the effect of noise for clarity.”
2. Aperture/Depth‑of‑field confusion
- Several comments clarified the counter‑intuitive f‑number system.
- sneela: “low number = blur.”
- 4gotunameagain: “The larger the entrance pupil is, the narrower the depth of field is.”
- armadsen: “f is the focal length… an aperture value of f/2 means a 25 mm entrance pupil.”
3. Simulator as a learning tool (and its limits)
- Many praised the interactive demo for teaching exposure trade‑offs, while noting missing features.
- moon2: “This is honestly the best and most simple way to learn photography.”
- JKCalhoun: “I think it is excellent… but its shutter/ISO visual for showing the image over/under‑exposed is not quite correct.”
- turnsout: “It needs to be updated to do its calculations in linear light, but it's probably useful for getting an intuitive sense of what the different levers of photography do to an image.”
