If your image is not sharply focused, then you should probably not bother keeping it, regardless of how well it was composed or how amazing its colors may have been. Instead, you should probably just get rid of it. Figure out how to perfect your focus so that your photographs will always be pin-sharp.
There was once a magnificent time in an age that has long since passed into oblivion when photographers had to really perform all of the focusings on their own. In days gone by, cameras and lenses did not have the same level of technological advancement that they do today. As quaint as it may sound, this meant that they could not instantly focus on a subject with alarming consistency and accuracy with just a little half-press of a button.
However, as the research and development of gear have progressed, so have autofocus systems. As a result, we are now at a point in history where it is easier than it has ever been to take photographs of subjects that are beautifully focused at an incredibly high hit rate. However, it is not 100% reliable.
This takes us to this fantastic video by Henry Turner, in which he explains how to make your photographs have a focus that is pin-sharp all the time. It is important to note that Turner is primarily a landscape photographer; hence, that is the perspective from which he is speaking in this video; nevertheless, he does highlight two very important topics: how to concentrate, as well as where to focus.
When you have a subject that is so prominent that it completely overpowers everything else in the frame, deciding where to put the focal point of your camera may be a pretty straightforward process. If, on the other hand, your image has a lot of depth to it and fascinating components in the front, the center ground, and the background, then the decisions you have to make will be a little trickier. This is something that Turner discusses, so have a look at the video and let me know what you think about it.
