Have funny looking curves or skewed lines at the edges of your wide-angle photo? The culprit which causes this is called barrel distortion.
Fear not. Barrel distortion can be corrected via many image editing programs which have tools to correct camera lens distortions. Photoshop was used to illustrate this tutorial, but many photo editing programs have similar tools. Check your software's HELP menu as the tool may be located under a different menu, or called by another name.
