Photography for geeks
> Telephoto optics tend to produce shallow DOF; wide-angle lenses keep almost everything in focus most of the time.<p>Isn’t this incorrect?<p>I.e. the article itself states that telephoto is just a crop of the wide angle. And sure, the background gets “larger” and if that changes the composition, it might make it look less busy. But the DOF (blur factor) stays the same.
