Changing the resolution by enlarging the pixels

Album allows you to resize your images in certain instances. You should be careful in choosing a new size that is a significant increase from the original. What happens is that the original number of pixels is spread across a larger area resulting in pixelated mush, as shown in Figure 3-3. Here are a few scenarios in which you want to avoid increasing the size of images with small pixel dimensions:

i Web Photo Gallery: I took a small photo of a dog, which had dimensions of 66 x 100 pixels. When I created my Web Photo Gallery, I chose X-Large in the Resize Photos option and set the quality to Medium. The result from enlarging a photo with such a small number of pixels to full-screen view was an indefinable, grainy animal (refer to Figure 3-3). I then took a new photo of the dog with pixel dimensions of 2048 x 3072 and used the same settings. The result was a happy dog — sharp and recognizable.

Be careful of increasing the size of images with small pixel dimensions or you may get junk.

^ Slide Show: Similarly, if you take a photo with small pixel dimensions and use it in Slide Show creation, Album responds with a warning that your image is low resolution and will not display well at this size.

^ Greeting Card: When you take low-resolution images and try and use them in creations such as greeting cards, which are intended to be printed and require images with higher resolution, Album warns you that the images you chose are below optimum resolution for printing.

All the preceding scenarios involve taking the set number of pixels in an image and spreading them across a larger area, whether on-screen or on paper. The result is larger-sized pixels and therefore a chunkier, pixelated-looking image. Enlarging pixels isn't recommended. The best thing to do is to start with images that contain enough pixels for their intended end-usage size.
