Convert EPS to HDR

An EPS file format is used for vector images in which points on a Cartesian plane are joined by lines and curves to form different shapes especially polygons. The added advantage to vector graphics is that they can be scaled up and down to any resolution. Emblems, figures, drawings, logos and other artworks can be saved using this format. Furthermore, it may have 2-dimensional vector graphics, text and bitmap images. As well as, a low-resolution image preview within the text document can be sent or received by an individual in it. One can also transfer the image between two or more operating systems, which makes it compatible format and that is why it is widely used by publishers. It is a standard format for storing both images and drawings within a postscript document.

An EPS file has a Bounding Box DSC comment(the smallest enclosing box for a point set in infinite dimensions) which describes the rectangle that contains an image. This information can be used by the applications to configure or layout the page, even though they are not capable of directly rendering the Postscript inside. Resizing, editing and manipulation of the image can be done using different software like Corel Draw and Adobe Illustrator and there will be no effect on the quality. There are at least two necessary document structuring conventions(DSC) header comments and this adapts to Version 3.0 as well as to bounding box comment( it tells about the size of an image). There can be optional DSC comments. For instance, the %%Begin(End)Preview and it denotes the bitmap preview section.

These files are also termed as Radiance HDR or HDRI. This format is used to store raster images or digital photos. In this, there is a grid of pixels where every pixel depicts a solo color within the image. Additionally, it has the ability to enrich the color and bring brightness to the pictures. Furthermore, it works well while processing the dark shadows and also on the washed-out areas of a picture. Hence, it is very useful to capture real-world scenes that have high brightness or direct sunlight and as well as extremely shady area or fainted nebulae. These images are the result of numerous different and narrow range exposures of the same matter.

HDR images offer the same luminance(an amount of light that is either emitted from or passes through or reflected from a particular area) that of the human visual system. ‘Stops’- Exposure Value differences are used to measure the dynamic range of photography. To double the amount of light, there should be an increase of one exposure value or one stop. Contrary, to decrease the amount of light to half of its value, there should be a decrease of one EV or one stop. Consequently, the darkest parts of shadows require high exposures when something in detail is to be revealed and low exposures are needed when there is a high level of brightness. It uses bracketing which means several shots are taken of the same subject using varied camera settings. Then these images are merged using a photo manipulation program to produce a single image.
