Some cameras provide options for fine-tuning settings such as sharpness and saturation, which may be referred to as "Styles" or "Films". Some cameras offer color-altering settings to do things such as make the photograph black-and-white or sepia, swap specific colors, or isolate colors.
Last week, GoPro announced the Hero4 Session, a small, square camera that doesn't need a waterproof housing. The diminutive size and simple controls (one press turns it on and starts it recording ...
Nearly all digital cameras can process the image from the sensor into a JPEG file using settings for white balance, color saturation, contrast, and sharpness that are either selected automatically or entered by the photographer before taking the picture. Cameras that produce raw files save these settings in the file, but defer the processing.
The first GoPro Hero, a film camera encased in a waterproof shell. The company was founded by Nick Woodman in 2002. [10] He was motivated by a 2002 surfing trip to Australia, in which he was hoping to capture high-quality action photos but could not because amateur photographers could not get close enough or buy appropriate quality equipment at reasonable prices.

For the 35 mm lens shown, if it were desired for the DOF to extend from 1 m to 2 m, focus would be set so that index mark was centered between the marks for those distances, and the aperture would be set to f /11. [f] On a view camera, the focus and f-number can be obtained by measuring the depth of field and performing simple calculations.
System sharpness is affected by the lens (design and manufacturing quality, focal length, aperture, and distance from the image center) and sensor (pixel count and anti-aliasing filter). In the field, sharpness is affected by camera shake (a good tripod can be helpful), focus accuracy, and atmospheric disturbances (thermal effects and aerosols).
The hyperfocal distance is entirely dependent upon what level of sharpness is considered to be acceptable. The criterion for the desired acceptable sharpness is specified through the circle of confusion (CoC) diameter limit. This criterion is the largest acceptable spot size diameter that an infinitesimal point is allowed to spread out to on ...
