Photometric Noise is a plugin for Adobe Photoshop that simulates CCD camera noise. The image sensor employed by most digital cameras is called a charge coupled device (CCD) that converts light into electrons. It then reads the accumulated charge of each cell in the image and an analog-to-digital converter (ADC) turns each pixel’s value into a digital value by measuring the amount of charge at each photosite. As with most CCD sensors, unwanted artifacts can sometimes be visible in low-light conditions that manifest themselves as noise in the dark areas of the image. Photometric Noise simulates this low-light noise effect.
Photometric Noise provides a simplified interface with a set of easy to use controls. The amount slider specifies the amount of prevalent noise while the photometric button toggles between normal and photometric noise. A photometric noise curve controller allows the user to modify the black to white curve with a handy visual display built right into the interface.
Photometric Noise offers fixed, additive and subtractive noise application options.
