There are currently 3 software solutions for raw conversion + post production on the
images:
• Seitz raw converter
• Adobe camera raw (+ Photoshop)
• Adobe Lightroom (+ Photoshop)
Both camera raw and Lightroom use the same base technology for their raw
conversion (linear interpolation), while the Seitz Roundshot D3 software and Seitz
raw converter uses conversion algorithms which are specifically designed for the
Seitz D3 digital scan back sensor. This is why the Seitz raw converter allows best
image quality.
Open the dng file with the desired application. The raw image will be converted
automatically into an RGB image preview using a given demosaïcing method. All
colour management options (such as white balance, HSL), tonemapping and filtering
(for example to reduce colour noise) are applied simultaneously on the raw image.
The image can then be further processed in Photoshop.

Focus on the following points to obtain the highest possible
image quality:
• Framing: it is recommended to capture an image containing
slightly more angle than necessary to have higher flexibility
in framing
• Exposure: make sure to obtain a perfect histogram. This
ensures that the exposure is precise and no additional post-
processing (and loss of quality) is required.
• Sharpness: work with focusing, aperture, rotation point and
distance setting in the software to obtain the best possible
definition. Of course sharpness can be enhanced in post-
production, but the better the original image, the more
natural the final image will be.
Raw saving: save the image in raw format DNG. Any other
format will contain an already converted image with non-
reversible operations reducing the adjustment possibilities.
All other parameters can be readjusted later during the
raw conversion with no risk of data loss, including white
balance, tone mapping etc.
