In Digital photography, enhancement is very helpful to help you edit your pictures. Sometimes an original looks so bad, it appears as if nothing can be done to help it. Not true! A couple commonly used enhancements are angle correction of slanted pictures and barrel and pincushion correction. The angle correction basically defines itself in the title.

If the picture is slightly titled then the angle correction enhancement will help it out quite a bit. One thing the tool needs to have is anti-aliasing. Barrel and pincushion correction is used to fix slanted horizons that were caused by the camera being used to zoom up as far is could go. These enhancements are used mainly for generally annoying changes that some people wouldn’t even notice unless it was dramatic, but are useful nonetheless.

What is re-sampling and how does it compare and differ from resizing? Both these tools are used to either enlarge or reduce a photo. Re-sampling is a little less heard of than resizing but a nice image editor will have it. The difference is this: re-sampling is actually the use of algorithms that you can select that will either re-calculate the amount of pixels (reducing the size of the image) or use interpolation to enlarge the photo. Re-sizing is a lot less complicated.

All it does for enlarging is double the pixels and for reducing the image it just takes pixels out and sometimes completely deletes thin lines in the picture. Re-sampling is the preferred method for professionals because the image comes back clear and appearing unchanged. Resizing doesn’t work as well; it is the preferred method for beginners and amateurs because it is quick and easy. The picture ends up being blocky and choppy and won’t look as nice as re-sampling. Most image editors will have the option of both.
