Culturegrid is a huge index of cultural assets in the UK (books, photographs, videos, locations8230;), and has a search API. At the moment it doesn8217;t return the large images for the URLs it indexes. This adds that feature.
Camera motion causes blur. Though some photographers claim to be able to hand hold a camera steady at slow shutter speeds-V8221; sec. or even slower-it takes only a slight amount of camera motion during exposure to cause a noticeable blur in an image. If a sharp picture is your aim, using a fast shutter speed or supporting the camera on a tripod is a much surer way to produce an image that will be sharp when enlarged. 8230;
ONull is an image based Vector Generator for Mac OSX. It allows the user to convert images into rasterized vector graphics. This tool was developed to give graphic designers the ability to transform small images from the Internet into printable and editable graphics.
There are a number of photographic processes which enjoyed great popularity in the early year of the century. In some the actual photographic print formed only an intermediate stage in the production of the final image. Typical examples are carbon processes, the carbo process, and the bromoil processes. Of these three, the bromoil process is probably easiest to master, in terms of technique and availability of suitable materials. 8230;
View cameras come in a variety of sizes, ranging in inches from 2 1/48243; x 3 1/48243; up to 11 x 14 formats. There are larger models, but those are usually used only for special-purpose photography because of the limits imposed by their massive size and weight. The two most popular sizes are 4215;5 and 8 x 10. All monorail cameras are modular in design. These can be specifically configured in terms of bellows, monorail length, and type of back and front components to serve a wide variety of photographic needs. 8230;
The view camera is unique because its lens and back are not rigidly fixed in one position; they can be moved readily. These movements change the relationship between the film and the lens and consequently reposition the area of sharpness or alter the shape of the subject. Each movement produces a specific effect and is defined in relation to the camera8217;s neutral position. 8230;
These movements alter the position of the image-up, down or sideways with respect to the film (Fig. 50). Identical results can be achieved with the swings and tilts combined with a change in the angle of the camera bed. There are two reasons for using the risingfalling and lateral adjustments, however. 8230;
Either the lens or the back adjustments can be used to control the plane of sharp focus, whereas the shape of the image is controlled solely by the back. Both the lens and back can be adjusted when either one alone does not provide sufficient control. However, if it is necessary to control shape and the plane of sharp focus on the same photograph, the back must be used to control the shape and the lens to control the plane of sharp focus, and the back must be adjusted first. 8230;
As the bellows on the camera are extended in order to focus and magnify the image, the amount of light reaching the film decreases rapidly. To ensure an accurate exposure it is vital to compensate for this loss of light by opening the aperture in the lens or by adding more time onto the shutter speed. This can be calculated using the following method 8230;
