Providing a combination of large, high-resolution files, extraordinary detail, and superb control of color and tones, Better Light scan backs have been the camera of choice for some of the most successful advertising, commercial, industrial, art repro and archival applications in the photo industry.Scan Back Insert The technology used by Better Light is totally different from the single-shot digital capture cameras using area array sensors (CCD and CMOS). Our scan backs gather the information for the image in one continuous scan as the light is collected by three, individually filtered rows of pixels – this is called a tri-linear CCD. Since it moves across the “film plane” capturing light one row of pixels at a time, it will take several minutes to complete a large file. On the other hand, no other camera is gathering such a huge population of pixels (often 144 Megapixels or MORE) over such a large format area of nearly 3”x4”—that’s 5X the physical area of most array sensors! And, all of the pixels are PURE, true RGB color, not interpolated color by the camera software. Some people resist the need to use a continuous light source instead of electronic flash…..and you cannot (easily) shoot any people or subjects that have motion. The benefits, however are significant: Huge file size; pure pixel color; normal 4x5 view camera operation and lenses; adjustable resolution (file size) independent of the ISO range to as high as 3200; plus the award-winning software and tremendous customer support – putting Better Light into a totally unique class of digital backs. If you are using the scan back for product work, you will not have the moiré issues and noise problems that most of the other digital cameras experience. Your Better Light scanning back adds the benefits of true, large-format digital capture – without compromise. For art reproduction….THERE IS NO BETTER CHOICE. The Better Light backs provide extremely sharp focus, wide dynamic range, total control of your image tone range, extraordinary adjustment of density (exposure) in less than 1/10th f-stop steps.
