At this point, I have no technical skills, or special knowledge of how to use a Reflex and what makes a photograph. The notions of “Focal”, “Opening”, “ISO”, … did not really make sense to me.
Then, little by little, I began by consulting many blogs and tutorial sites to learn more about the theory and get familiar with the technical terms and settings. In parallel, I implemented what I learned, I experimented with practice, I did tests, mistakes.
Nothing like practice and failure to progress. A little patience and obstinacy help too!
