What is the meaning of the macro and Digital Zoom in the image?

There are a few tips from people I do not use digital zoom and use macro configuration, but what does that mean? freaking me reject the image .. Sorry for this http://bunchofplayer.blogspot.com .. Yes, make two questions here .. and not related! Sorry!

Macro Photography: Refers to the photo in the foreground the classical definition that the image projected on the level of "film" (ie, film or digital sensor) is about the same size as the subject. In the 35 mm (for example), the objective is typically optimized to focus on a small area close to the image size cinema. Most 35mm format macro lenses achieve at least 1:2, ie, the image of the film is 1 / 2 the size of the object photographed. Much 35mm Macro 1:1, ie the image on the film is the same size as the object photographed. Another important distinction is that the objectives designed for macro are generally in Good Shape on distance Macro Focus and are not as sharp at other focus distances. In recent years, the macro term has been used in marketing materials in the sense of being able to focus on a subject close enough that when a regular 4 × 6 inches (102 × 152 mm) print is made, the image size or larger. This requires a magnification ratio of only about 1:4, more easily attainable by lens manufacturers. Digital zoom: Digital zoom is a method of decreasing () reduce the apparent angle of view photographic image or Digital Video. Digital zoom is accomplished by cropping an image to an area centered on the relationship with the same look as the original and usually also interpolating the result to the original size of pixels. Is done electronically, without any adjustment of the optical camera and no optical resolution is gained in the process. Because interpolation disturbs the original design of the pixel of the image captured by the Image Sensor camera is generally considered detrimental to image quality. The results of digital zoom, However, sometimes exceeding the results of manual cropping and resizing (interpolation) in post-production. Because the camera May enforce its interpolation to perform image compression with loss, preserving the small details that otherwise would be lost. For cameras that save images RAW format, however, resizing in post-production yield results equal or superior to digital zoom.
