Photoshop Tips - One of Many Steps to Instant Photography
Filed Under camera and photo
All of us wonder the logic behind the instant print of any digital photograph. The process involves a series of individual images that are captured instantly within nanoseconds and overlapped on each other producing the final image. This series of activity is collectively called work flow of digital imaging. The digital photography process does not end there. There are post photography workshop activities involved. The series of activities include saving the data from the digital camera to the hard disk, giving a quick revision for image quality, storing the photographs in to folders, making minor or major changes in the images using softwares, and publishing. The combined set of these activities is collectively called “editing digital photographs.”
Photo editors are computer programs that are specifically designed to manipulate digital images. Though the code of commands is available under different labels the principle of operation can be grouped under raster, 3D or vector imaging. The code or the photo editor programs can be used to create new images that seem to be shot from a real life situation or it can be used to modify already prevalent images.
Selecting the part of the image to be edited is the first step in any digital editing process. There are certain images that may require minor alteration in a particular part of the image. In such cases it is unreasonable to implement changes to the whole image. Thus selective editing is required. Selective editing is accomplished by many tools such as vector based pen tools, lasso, and marquee. The latest digital editing methods comprise of composting, masking, edge detection, and channel editing.
Layers are the most useful utility tool in any photography editing process. Layers are a set of transparencies stacked on each other. A set of layers stacked on each other forms the composite of 3D images. The layers for the whole series of work flow in any imaging process. This work flow methodology is the foundation that enables nondestructive editing of any digital photograph.
Image editors are used to scale any image. Image scaling is used to maximize and minimize images sizing. In short image scaling refers to resizing of any digital image. Latest digital cameras produce images of very high resolution and larger images. The images thus produced can be minimized for internet publishing. Image editors work on the principle of sampling. Sampling is the process in which the resultant pixel values of resized images is calculated. The resized images will have varying values than the original image as they are either minimized or maximized in size.
Cropping is one technique in digital photography, which is used to delete unwanted portions from a digital photograph. Cropping has nothing to do with bringing down the resolution of the image. Rectangular selection of certain undesired portions of the original image is done, followed by few patch works that result in an image of required output. The main purpose of cropping is to remove any undesired image composite from the graphic image.
Digital editing can be done by thousands of methods. All the methods cannot be explained in a single article. This article series will speak of other techniques in the oncoming follow up tutorials.
