Eva in London • Eva à Londres - Trafalgar Square

Eva is spending 6 months in London... I jumped on the opportunity to create an environmental portrait in the iconic location of Trafalgar Square:
Eva passe 6 mois à Londres... j'en ai profité pour créer un portrait "in situ" que j'avais en projet depuis un bon bout de temps, dans un lieu reconnaissable entre tous de la capitale britannique - Trafalgar Square :

Eva settles in LondonEva settles in London Beyond the carefully selected location and focal length required to get the composition (long lens for perspective compression), chosing the right time of day (evening in Summer) was also key to get a suitable lighting... but we were particularly lucky with the dramatic sky and the sun beam illuminating the square. We "just" had to be patient and "work" around the hordes of tourists walking in front of the statues - or queuing to climb them...
Au delà du choix de l'endroit et de la focale pour avoir la composition désirée (télé pour compresser la perspective), choisir le bon moment de la journée (soirée d'été) était clé pour obtenir un éclairage adéquat... mais nous avons eu beaucoup de chance avec le ciel tourmenté et le rayon de soleil sur la place au bon moment... I nous a juste fallu nous armer de patience avec les hordes de touristes qui passaient devant les statues ou faisaient la queue pour grimper...

If the above portrait is my favorite by far, I also like the below variations (for which unfortunately the sky was no longer quite as gorgeous):
Si le portrait ci-dessus est de loin ma préférée, j'aime aussi ces variantes (pour lesquelles le ciel n'était hélas plus aussi beau) :

Incidentally, this series is a pretty good illustration of how relatively small changes in position (distance and angle vs. subject) and focal length can lead to a great variation of results: Big Ben appears smaller or larger, in one place or another, by just moving a few steps backward or forward, left or right, and adjusting the focal length (zoom) to maintain the composition constant. Also, the impact of depth of field (driven by the aperture) is very significant: on the first portrait, taken at f/10, Big Ben is quite blurred. It's much sharper on the other ones, taken at f/16 (and higher ISO to have a high enough speed to have sharp images even though they were taken hand-held).

Au passage, cette série est une bonne illustration du fait que des changements relativement minimes de position (distance et angle par rapport au sujet) et de focale peuvent aboutir à des résultats très différents : Big Ben parait plus ou moins grande, à un endroit ou un autre, simplement en se déplaçant de quelques pas en avant ou en arrière, à gauche ou à droite, et en ajustant la focale (zoom) pour conserver la composition constante. Aussi, l’impact de la profondeur de champ (conditionnée par l’ouverture) est important : sur le premier portrait, pris à f/10, Big Ben est assez floue. Elle est beaucoup plus nette sur les autres, pris à f/16 (et à des valeurs d’ISO beaucoup plus importantes, de façon à maintenir une vitesse suffisante pour assurer un bon piqué à ces photos prises à main levée).

More to come, stay tuned! A suivre !
