He exposed a silver-plated copper sheet to iodine vapor, creating a layer of light-sensitive silver iodide ; exposed it in the camera for a few minutes; developed the resulting invisible latent image to visibility with mercury fumes; then bathed the plate in a hot salt solution to remove the remaining silver iodide, making the results light-fast. He named this first practical process for making photographs with a camera the daguerreotypeafter himself. Its existence was announced to the world on 7 January but working details were not made public until 19 August.
In fact, it is depressingly rare to have it all come together in one moment. It must also be stated that what follows is not a recipe for creating great images.
Photography can only be practised as an art when personal interpretation is injected into the process — only use this information as a guideline for evolving your own images.
Converging lines have been used by painters for centuries to create the illusion of depth within a 2 dimensional medium.
This is why photos of wharves, roads, and rivers make such successful photographic subjects. Although many consider Digital forensic essay subjects to be cliches, I strongly council my workshop students to shoot them heavily to build an awareness of the power of a line in an image.
Leading lines not only draw attention into the image, they can also help to hold the eye within the confines of the image. Check out the crudely overlaid wharf image below combines the strong converging lines of the wharf with secondary supporting lines in the water, hills and clouds.
Look for these lines whenever you are shooting — they are almost everywhere. The pain is just your visual muscles growing stronger. Shooting man-made lines will teach you to look for more subtle lines in nature.
Although the wharf is the primary leading line device in this image there are a number of leading lines present in the water, hills and clouds. The darker reflected lines in the water help hold the eye in the central region of the frame.
Interesting Perspective As a photographer you are an artist not a forensic documentarian. Hence I rarely find myself shooting at my natural standing position. This is especially apparent when using an ultra-wide lens. Subject matter becomes incredibly diminutive and interesting leading lines really lose their visual power when viewed from 5 or 6 feet high — so try getting uncomfortably close and low.
Look for ways to gain elevation to find that privileged viewpoint — I find that this often works really well when shooting telephoto lengths for some reason. Getting uncomfortably low in this instance dramatically altered the perceived form of the rock on the lower right of the frame.
Note the strong leading line formed here also. Foreground Elements I believe that a dynamic image almost always possesses a strong foreground element, or elements, that complement the greater scene. Sure, spectacular light makes for great images, but personally photos that contain nothing but vast expanses of super-saucy red clouds do little to engage me as a viewer.
The best dynamic images typically have a strong point of interest in the lower half, or foreground. This is your visual entree into an image. If your foreground element happens to include leading lines you are quite possibly onto the much vaunted money-shot.Forensic Psychological Assessment in Immigration Court is an essential specialized guide for psychologists and clinicians who work with immigrants.
