PNG – is a scan-line graphic format developed as an alternative to GIF, a commercial license. However, they are both raster image types. PNG is based on the best features of the predecessor, including lossless compression and transparent background support. The PNG technology ensures the preservation of all stages of editing and the restoration of the step by preserving the quality. However, it does not allow us to save several pictures in one file at once, limiting its use in the development of animated images.

The PNG extension was proposed as a tool that helps to transfer and store images on the World Wide Web. The technology is limited to an 8-bit transparency channel so that you can adjust the colors from opaque to transparent. It supports 24-bit RGB colors, matching images, and shades of gray. However, as a non-professional format, PNG can not display other color spaces. Most programs allow you to open such files. They can also run in any browser. Images are different in small weight with good quality.

.hdr

This format is used to store bitmap images but otherwise has enhanced performance levels of color and brightness. It blends exposures to capture indistinct tones in the shadows or detail the areas highly illuminated in an image. HDR has the ability to combine numerous images which differ in their distribution of light leading to the creation of quality images.

The pixel value of a HDR file can enclose the entire tonal range that exist in the real world. Images have the ability to show the largest possible range of pixel values. Capturing direct light and utmost shadows present with color portrayed in a manner that is life like. The creation of HDR can be done in two ways, by combining different photographs in a certain way or through the use of image sensors that are unique.
