Digital Image Resizing One aspect of digital images which seems to cause a lot of confusion to beginners is the matter of image size. There are three basic measures of image size Pixel count - e.g 3000x2000 pixels Physical size - e.g. 4" x 6" Resolution - e.g. 72 pixels per inch (ppi) The confusion seems to arise because people aren't sure of how these are related. They wonder if ppi affects the size of the image you see on a monitor screen. Digital image files are "tagged" with other information. Pixels When you display a digital image on a monitor using a web browser, the only thing that determines the size of the image is the width and height in pixels. So I'll say this once again. For example here's a screen from PhotoShop (and PhotoShop Elements) which allows you to change the pixel width and height of the image. You can see here we are starting out with an image which is 1000 pixels wide and 640 pixels high. Of course you can make images larger as well as smaller. Pixels per Inch Dots Per Inch
HDRengine Accessible and Easy Fast ... and Fun! Accurate and Pro What is HDR photography? The human eye possesses a unique characteristic: it can perceive at a given time a much wider range of tones, colors and luminosity than what cameras are capable of capturing today. It means that a single photo will never be able to render what your eyes saw thru the lens in the first place, especially when confronted with a scene with a very large range of luminosity, typically a scene featuring a bright sun and deep black shadows. High Dynamic Range -HDR- is a technique that allows capturing a larger dynamic range between the lightest and darkest areas of a photographed scene by merging multiple exposures of said scene. Three reasons to get into HDR photography Take pictures that were simply impossible to capture before Edit and improve your pictures like a professional photographer Many professional photographers and advanced amateurs also use HDR tools to edit single photos.
