For best results always check the "keep proportions" check box for the best results. If this box is checked you only need to give the new width in pixels and the height that keeps the proportions of the image will be automatically calculated or vice-versa. Often you will also be able to choose a percentage for the size reduction instead of a width/height in pixels. Often you will also be able to choose a percentage for the size reduction instead of a width/height in pixels. If needed, try using the “unsharp mask filter” to help sharpen the image.
What does all this mean? Why even perform resampling in the first place? To reduce file size for emailing and web posting. As an example, selecting reduce by 50% using the Lanczos3 filter, I recently resampled 24 pictures using the “batch convert” feature in FastStone Image Viewer. This process only took a matter of minutes and reduced the total file storage for all 24 images from 69MB to 11.8MB. Even with this huge reduction in file size, there was almost no visible difference when viewed on the computer screen. NOTE: Always save the ‘resampled’ images to a new folder. That way when you are done with your emailing or uploading to your web or blog site, you can simply delete the folder, leaving the originals intact.
