Learning from failed pictures

When taking pictures and they are missed, we tend to keep them to yourself or to forget, and this is after all quite natural. With almost instant viewing snapshots allowed by the digital cameras, and despite the excessive storage space offered by the memory cards, some even missed just delete their pictures after taking them.

But take advantage of these failures can progress.

 Miss, or not ... I find a few causes why it is interesting to keep all the photos that we have the opportunity to take over an output.

Firstly, in order to take time quietly watching his shots and analyze the reasons that one of them is missing (or successful). It does not replace the control in the heat of the action or automation that can be acquired with experience, but it is important to understand some particular aspects that go beyond the "simple" camera shake or overexposure.

Secondly, because the screen of a camera can be misleading, and that it is better able to judge the success of a picture on a screen worthy of the name. And even a photo would be missed, a portion will be usable anyway. With the power of today's sensors, it would be surprising not to crop an image.
Speaking of image processing, most of the software we use today are able to play with the brightness, contrast, etc.. Why not try to "catch" a failed photo?


With digital cameras, we took the reflex to look at our shots just after taking. Some children have never even seen anything other than NPC and are quite surprised when they come across a film camera. On an SLR, this allows instant viewing to know quickly if you have selected the right settings, and thus avoids wasting sockets for anything on film.
Overexposed

A photo that could have been successful if it was not overexposed
But it is easily tempted to remove a failed photo, certainly remember the first camera on which the memory (internal or external) was much more limited than today, and where few megabytes by removing earned to blur or overexposed proved very useful.

When the blithely exceeds ten gigabytes on an SD card, the need for storage capacity is no longer an excuse. Should we speak of shame, or stupidity, when you remove too hastily failures clichés?
