Photographic functions.

angle-of-view clj/s

(angle-of-view focal-length size)

Calculates the angle of view of an image for the given focal length and sensor size.

diagonal clj/s

(diagonal a)

(diagonal a b)

Calculates the diagonal of a rectangle.

exposure-value clj/s

(exposure-value f-stop shutter-speed)

(exposure-value f-stop shutter-speed iso)

Calculates the exposure value for the given f-stop and shutter speed.

f-stop clj/s

(f-stop exposure-value shutter-speed)

(f-stop exposure-value shutter-speed iso)

Calculates the aperture for the given exposure value and shutter speed (with the optional iso value).

hyperfocal-distance clj/s

(hyperfocal-distance focal-length f-stop)

(hyperfocal-distance focal-length f-stop circle-of-confusion)

Calculates the hyperfocal distance for the given focal length, f-stop and optionally the circle of confusion.

hyperfocal-distance-approximation clj/s

(hyperfocal-distance-approximation focal-length f-stop)

(hyperfocal-distance-approximation focal-length f-stop circle-of-confusion)

Calculates an approximation of the hyperfocal distance for the given focal length, f-stop and optionally the circle of confusion.

iso clj/s

(iso exposure-value f-stop shutter-speed)

Calculates the iso value for the given exposure value, f-stop and shutter speed.

panoramic-image-count clj/s

(panoramic-image-count focal-length size)

(panoramic-image-count focal-length size overlap)

(panoramic-image-count focal-length size arc-size overlap)

Calculates the number of images needed for a panorama given the focal length, sensor size, panorama arc and overlap.

pixel-size-eos600d clj/s

shutter-speed clj/s

(shutter-speed exposure-value f-stop)

(shutter-speed exposure-value f-stop iso)

Calculates the aperture for the given exposure value and f-stop (with the optional iso value).
