SPECIALIST HARDWARE FOR IMAGE CAPTURE pincushion distortion on long-focus lenses of telephoto configuration. Every lens manufacturer sets its own minimum image quality acceptance standards. Higher prices often mean stricter quality control, so to satisfy the critical demands likely to be made of you, it is sensible not to economize in this area. | SPECIALIST HARDWARE FOR IMAGE CAPTURE pincushion distortion on long-focus lenses of telephoto configuration.

PROFESSIONAL INTERIOR PHOTOGRAPHY 30 3 RECORDING MEDIUMS FILM VERSUS DIGITAL The era of high quality digital imaging has now well and truly dawned and digital imaging has become the mainstream alternative to film and in some areas the dominant alternative. It is an area that all practicing photographers will be addressing seriously if they have not already done so. The aim of this chapter is to clarify and lay bare the facts of traditional silver halide photography in comparison with those of modern digital technology. Both film and digital image capture share many common characteristics. Both record light reflections received at the image plane onto a light-sensitive medium with the objective of reproduction at some later stage. While the eventual output can appear very similar the routes to achieve it are technologically quite different. The silver halide technology of traditional photography produces an analogue continuous tone image where quality is limited by the grain size of the individual halide crystals. Digital images by comparison are electronically created stepped-tone images based on the binary digital system where 0 is black and 1 is white in its simplest form. An image is recorded as a framework of millions of pixels the smallest distinct units or picture elements of a digital image that are encoded with the varying intensities of the colours red green and blue that make up the image. Being well versed in the practical aspects of film technology as most of us are this section will feature Ashley Morrison a photographer with several years practical experience of shooting interiors digitally.
