The RAW data is “raw” data that is recorded data before carry out image data processing for captured data. When taking a picture, firstly the light of CCD caught is converted into electronic signal.This electronic signal is carried out image data processing to edit image data then image data is recorded. This recorded image data is JPEG or TIFF. On other hand, the Row data is directly recorded “raw” electronic signal before carry out image data processing. The Row data which is not carry out image data processing, if forward to the computer as it is, can not see as image with regular software. Therefore, the image data processing is necessary with software [PENTAX PHOTO Laboratory 2.0] which is packed with the *istDS camera.But when playing back image on the LCD monitor of camera, the row data which is before carry out image data processing can be displayed. Also when playing back image on the TV monitor with connecting Video cable, it can be displayed.
