developed heliography (created world's oldest surviving product of a photographic process: a print made from a photoengraved printing plate in 1825)

Nicéphore Niépce

oldest surviving photograph of a real-world scene

Niepce in 1826 or 1827 used a primitive camera to produce it

Tablotype or calotype

daguerrotype

made it possible to capture the image seen inside a camera obscura and preserve it as an object. It was the first practical photographic process and ushered in a new age of pictorial possibility.

calotype

the image was produced on paper treated with silver iodide and developed by sodium thiosulphite

fast lens

lens with a wide maximum aperture. The larger the maximum aperture, the faster the lens (f/1.4, f/1.8, f/2.8.)

minimum apperture to freeze normal everyday action (walkin person)

1/125 (everyday photos, landscapes)

what shutter speed u start to get some motion blur of a walking person

1/60 1/20

which shutter speed is the minimum before getting motion blur with a had handled camera

use shutter speeds equal to or faster than one divided by your focal length. 35mm lens, you should use shutter speeds equal to or faster than 1/35 of a second.

which shutter speed is the minimum before getting motion blur with a had handled camera

Typically, your hands won't add noticeable blur if you're using a shutter speed around 1/50 second or faster, but it strongly depends upon your lens

which shutter speed for northern light

30s

which shutter speed for driving car

1/125 or faster) and use panning. In other words, follow the moving car with your lens and snap your photos.

high speed synching

(HSS) allows you to use your flash at a shutter speed that goes above 1/200 of a second, which is a normal flash sync speed on most digital cameras. HSS allows you to set the exposure for a dramatic sky and still get a good exposure on the model as well.

high speed synching

when you want to use a shutter speed that is faster than your camera's native flash sync speed, or when you want to use a wider aperture setting that requires a higher shutter speed as is often the case with outdoor daylight shooting.

limit of shutter speed for flash photography without hss

1/200 sec or 1/250 sec
