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.
Hi guys, please don't forget to seed. :) Thank you!
