February 2011 – Complete Digital Photography

Many of the creative options available to a photographer hinge on an in-depth understanding of lenses. Foundations of Photography: Lenses, will give you that in-depth understanding, as you learn how to choose lenses and take full advantage of their creative options. This 2.5 hour course covers fundamental concepts that apply to any camera, such as focal length and camera position, and shows how to evaluate and shop for DSLR lenses. The second half of the course focuses on shooting techniques: controlling autofocus, working with different focal lengths, and managing distortion and flare. You’ll also learn about filters, cleaning, maintenance, and more. You can find it all right here on the Lynda.com web site.

The last step of any photo workflow is to sharpen and output. If your final goal is an image for the web or email, then output simply means resizing and saving your image. If your final output is to print using an online printing service, then you’ll need to follow their size, resolution, and format specifications very carefully. Similarly, if your final destination is your own desktop printer, you’ll also need to set size and resolution before you print. While choosing size is pretty simple – you just resize the image to the printing dimensions that you want – choosing a correct resolution is a little trickier. In this article, we look at exactly what you need to consider when choosing a resolution for desktop inkjet printing.
