Photo Basics part 1. Cropping and resizing your imagesBy Brenda Essig aka Zanymuse (Zanymuse) on October 11, 2010
|When working with image files it is often necessary to re-size an image. Most cameras can take pictures in very high resolutions that make it possible to get wonderful high quality prints. On the web, those huge files are simply not good. They take much too long to load and waste a lot of server space. Before you start resizing all your images or cropping them take a few minutes to consider what you want to use the image for.|
...There are many ways to achieve a special look or feel to an image. The simplest is croping the image to remove the unwanted or unsightly things in the edges. Cropping away the unwanted portion allows the eye to fucus on the important part of the image without distraction.This leaves the file size smaller because you have removed some of the picture but the part remaining is still available in it's high resolution. The more you crop, the smaller the file size.
For example: I normally would NOT publish a picture of my unmade bed no matter how sweet I Think Pyxle looks.But when I was asked to contribute a nosey dog picture to a forum, I was happy to add her charming nose.
Always work with a copy of the original so that you can go back to the original if you need to.
Besides cutting out messy and embarrassing beds there are other reasons to crop pictures. I often crop to reduce the file size while maintaining the details of my picture. This works especially well when I am creating banners and using pieces from several images to create a single image or when I want to use a slice of an image as a banner by itself.
By taking the slice first from the full sized image I can avoid excessive distortion and blurring on the image and retain as much detail as possible.
As you can see in the example below, cropping the height of the image and leaving the width alone gives me a better view of the mansion on my banner while maintaining the images proportions.
The image had already been reduced to 72px resolution before it was added to the database. Since it was still a nice sharp image I was able to sucessfully crop it for use. If it had been available in it's original file size the details would have been even sharper, but for our purposes, it looks great.

These articles are not intended to teach experts but rather to encourage beginners to dig in and have fun. I am an amateur image manipulator versus a digital artist who actually creates images such as the amazing creations of Diana Smailus (Pastime).
There others here that have shown their images on various cubits whos work I have admired and I am hoping they will step forward with their knowledge and share it with us through articles. Any image related subject would be welcome from how to select a camera, how to photograph your products for your store, how to ...Won't you share your knowledge with us?
