I always use natural light at the streets, however I sometimes use artificial light at the studio (interiors or plain backgrounds are the key to know when I am using it). But you ask about technical issues and that is the wrong direction. To get a photography with "atmosphere" you have to create it at the location, that is about you as a person, the books and music you love, and the way to talk and relation to people, the poetry inside you... It has nothing to be with a camera or another, or a postproduction presets. If you live true your photography, work hard and give you your time to learn and to find what do you want to share to the world from your heart, you will have that in your photography, there is not another way.
Grosso modo, ne pas penser en termes techniques mais en termes artistiques et humains pour obtenir une atmosphère; prendre son temps, essayer plein de trucs pour en arriver à quelque chose qui plaît. Ce qui s'entend parfaitement, seulement sur certains points précis, comme la post-prod, je trouve ça un peu plus compliqué d'obtenir quelque chose de satisfaisant "à l'instinct". Après, il n'a probablement pas très envie d'expliquer au premier venu sa technique de post-traitement, ce que je comprendrais parfaitement.
