http://www.mindbites.com/lesson/2007-photography-image-resolution-editing-software When it comes to digital image resolution there are no constant factors. In the digital darkroom when we talk about resolution we are talking about dpi, which is dots per inch or ppi, which is pixels per inch, these terms are interchangeable. Understanding resolution is critical when you're capturing your photo input, working with the image and crafting the final photographic output. This lesson will explain to you what resolution means, how to think of it, and when it's high enough given your intended use for the image. The requirements for resolution levels vary by output medium (web, print, email, etc) and desired file format. Some file formats contain more dpi than others, and these generally are used for applications that require higher resolution images. In addition to image resolution, Brian will also cover digital photo editing software in this lesson. While cameras are important, your software will ultimately determine what can and can't be done with captured images. There are two basic types of software - Vector (usually for Art & Illustrations) and Raster (usually for digital images). There are pros and cons to each that Brian will walk through in this lesson once he explains how the two differ and how they are alike. In order to equip you to make the right purchase decision, Brian will also discuss the differences between consumer and professional programs and what value is added with the latter. He'll also talk about what to look for when making your decision, what the downsides generally are to software that comes packaged with purchased hardware, and he'll recommend trial periods to make sure that you're making the right call. The darkroom is the starting point for learning the fundamentals of digital image manipulation. This lesson is excerpted from the DVD, Digital Photography: The Darkroom, which is an excellent resource for those looking to learn the fundamentals of digital image manipulation. This is a segment cut from the DVD and includes chapter 5 and 6 which cover image resolution & darkroom software.
