Foveon X3(R) direct image sensor in the Sigma SD10 digital SLR can capture all RGB colors at each and every pixel. The revolutionary design of Foveon X3(R) direct image sensor features three layers of pixel sensors Using three silicon-embedded layers of pixel sensors, stacked to take advantage of silicon’s ability to absorb red, green, and blue light at different respective depths, the Foveon X3(R) direct image sensor can thereby directly capture full color and detail at each and every pixel location, without interpolation.With the RAW data recording system of the SIGMA SD10, it is possible to obtain high picture definition and compact file size. The lossless compression system of RAW data, eliminates image deterioration, provides superior pictures, without sacrificing original image quality and retains full image capture details.Depending on the intention of the photographer, the SIGMA SD10 allows photographers to select the resolution of RAW data images in one of three resolutions. HI mode (2268x1512x3 layers) delivers highest resolution image performance. MED mode (1512x1008x3 layers) has high definition and recording capacity. LOW mode (1134x756x3 layers) for capturing the most images per given memory capacity.The SD10 comes with SIGMA Photo Pro 2.0 software for modifying recorded RAW data image files. It is easy to make adjustments (white balance, exposure, color balance, and contrast for example) in three modes. The X3F mode stores the original settings of the image at point of capture. In the auto adjustment mode the software analyzes and automatically makes adjustments of RAW data. The custom -mode allows the photographer to make individual adjustments to exposure, contrast, shadow, highlight, sharpness, and saturation. The latest addition to Sigma Photo Pro 2.0 software is X3 Fill Light. This easy to use facility corrects tones on images of high contrast exposure or backlit pictures.In Default or normal mode the ISO sensitivity of SD10 can be set to 100, 200, 400 and 800. If Extended Mode is selected, it is possible to use ISO 1600 sensitivity. In any ISO sensitivity setting, it is possible to select a high shutter speed from 1/6000 sec. to a slow shutter speed of 30secs.SIGMA SD10 is equipped with a “sport finder” which offers a view that extends outside of the frame. The area that is out of the image sensor coverage range is marked by transparent light gray, to distinguish it from the active picture taking area.The Sigma SD10 records on reliable, high capacity Type I and Type II CF (CompactFlash) cards or a Microdrive to hold larger volumes of data.The SIGMA SD10 is equipped with a large 1.8″ appr.130,000 dot low temperature polysilicon TFT-LCD mo nitor with white LED on the back panel, which displays images, menus and histogram. The coverage area of the LCD monitor is 100%, of that seen from the viewfinder .
