Digital Photography Acquisition And Processing Techniques

Ron Reznik



The best photographs result from well-exposed, well-composed, properly processed images. This book is not intended to be
a camera or software manual which expounds on features... instead I prefer to go into detail regarding various
techniques which I use for the acquisition and processing of images. While I use Nikon gear, the techniques which I will
describe are applicable

to other manufacturers' products, and techniques described for processing images in Nikon Capture are applicable to
other RAW processing programs and image editors with a few alterations.



Some acquisition techniques which will be discussed include the use of the histogram to determine proper exposure; the
use of the various metering modes along with exposure compensation to achieve that exposure in various situations; some
reasons for the use of aperture priority, shutter priority or manual mode; techniques for composition of various sorts
of subjects; and the use of depth of field for subject isolation or to assist in the creation of a wide-angle
composition.



Special attention will be paid to the digital workflow, including organizational methods; batch-processing for
pre-selection (to remove unwanted duplicates or mistakes from the group to be processed manually); the selection process
itself; and a comprehensive treatise on image processing using Nikon Capture as well as some post-processing techniques
in Photoshop.



In my workflow, most of the image processing including the color work, White Balance, EV, Levels, Curves and Gamma
processing are done in Capture, with postprocessing being primarily used for touch-up, rotation, cropping, resizing,
etc. The section on processing is documented with screen captures and presented in easily-understandable language. 



An article on Lens Selection and sample images are also included, along with lessons showing step-by-step processing of
these images, which were selected to illustrate common histograms. There will also be auxiliary files included to help
you to understand luminosity and color, and how they apply to both metering and evaluation of the histogram.
