Enlarge Images
Enlarging an image by the resize function in Photoshop or another software will increase the number of pixels in the resulting image. However, the result image is not high quality and usually looks soft and blurry. Moreover, previously unnoticed imperfections of the image, such as noise and compression artifacts, will show up more clearly in the enlarged images.
Topaz Enlarge2X™ is designed to double image resolution. As an example, here is a small image in its original size.
Topaz Enlarge2X™ requires two steps to double the resolution of this image:
- Resize the image to exactly 200% using “Nearest Neighbor” re-sampling.
- Apply Topaz Enlarge2X™ filter to the resized image.
Now let do the example step-by-step. In Photoshop, use the resize function in Image->Image Resize… You will see the resize dialog. You need to do the following:
- Change both width and height to e200%.
- Make sure to check “Resample Image” and select “Nearest Neighbor”.
This step is very important since Topaz Enlarge2X™ can only work on an image exactly doubled in size with pixel duplication. Failure to do so will result in a less optimal result. Now you see the small image’s size is doubled. The enlarged image looks blurry with jagged edges. In addition, the previously unnoticeable noise (on the blue sky area) is more noticeable.
The result isn’t perfect, but it’s definitely better than a normal resize. Here we want to show that Topaz Enlarge2X™ provides you a tool to enhance resized image to a usable level.
