Five steps to discovering Fujifilm’s unique X-Trans technology

One of the most overlooked aspects of a camera is its ability to render colour, so this month we take a look at Fujifilm’s X-Trans III sensor & Film Simulation modes.

If you’re like us, then you’ll know how important it is to be able to get your shot as close to perfect in-camera as you can. Often, people take that to mean a well exposed image, strong composition and a good white balance, but Fujifilm always aim to take it one step further than the competition.

Thanks to the X-Trans III sensor, found in the current line-up of X Series cameras, such as the X-Pro2, X-T20, X100F and the X-T2, you can be certain that your colours will look near-perfect as soon as you hit the shutter button. It’s all thanks to the amazing technology at play behind the X-Trans CMOS sensor, which is based on a traditional Bayer colour filter array, but with a few very important and noticeable tweaks made by Fujifilm’s R&D department, which we will be taking a look at here.

Fujifilm also has the wildly popular and exceptional Film Simulation modes, which dig deep into its heritage as one of the world’s leading film manufacturers (a heritage which has been going since the company’s creation in 1934, when they aimed to be the first Japanese film manufacturer, creating anything from motion picture to microfilm and everything in between). These simulations are comparable to those that you’d find on many cameras, usually referred to as Picture Controls of Scene Modes, except they boast a far more impressive punch and evoke some of the finest moments of Fujifilm’s filmic history. These simulations include such iconic film recipes as Provia, Velvia, Classic Chrome and the newest edition, the black & white powerhouse, ACROS. With such an impressive resume of colour credentials, we’re now taking a deeper look at Fujifilm’s X-Trans sensor and amazing Film Simulation modes, to find out how they have created this technology and used it to manufacture some of the best cameras on the market.

Une réaction à la lumière | La sensibilité ISO

Tous les photographes connaissent désormais l’utilité et le fonctionnement des ISO. Ce paramètre étant devenu réglable en numérique, on peut, très simplement, le modifier en fonction des circonstances pour adapter l’exposition. On connaît également l’effet de l’augmentation de la sensibilité sur le bruit. Mais qu’est-ce réellement que cette sensibilité ? — Claude Tauleigne

La sensibilité mesure la réactivité (en termes de luminosité de l’image finale) d’une surface sensible à la lumière incidente. Schématiquement, elle conditionne la “réaction” quantitative d’un système pour une quantité définie de lumière parvenant sur sa surface. Cette capacité de réponse est mesurée après “développement” de l’image : on la détermine donc généralement en évaluant la densité de l’émulsion (pour un film) ou l’intensité numérique dans le fichier (pour un capteur numérique). Ainsi, pour une quantité de lumière fixe, l’image sera claire si la sensibilité est élevée… et sombre si la sensibilité est faible. Cette donnée est donc capitale : en connaissant la réaction quantitative de la surface sensible, le photographe est à même de moduler la lumière incidente (avec le diaphragme de l’objectif, l’obturateur de l’appareil photo, voire en utilisant des filtres de densité…) pour l’adapter à cette caractéristique.

5 points à retenir:
1- La sensibilité mesure la capacité d’une surface sensible à réagir à une exposition lumineuse (lumination). Elle se détermine en évaluant le signal obtenu (la densité d’un film ou l’intensité numérique d’un fichier).
2- La sensibilité est inversement proportionnelle à une lumination de référence, choisie pour procurer un signal donné.
3- La sensibilité est définie par des normes ISO. Elles sont parfaitement définies en argentique mais restent à l’appréciation des constructeurs en numérique.
4- Augmenter la sensibilité de base d’une surface sensible est intéressant lorsque les conditions lumineuses sont faibles. Cela consiste à augmenter l’amplification du signal en sortie de surface sensible.
5- Cette amplification se traduit par une dégradation du signal qui devient de plus en plus bruité. Les boîtiers gèrent mieux cette dégradation que les logiciels externes.

Should I shoot manual?

There’s a common misconception that learning to shoot in manual is the key that will unlock the door to more professional-looking images. In reality, most pros work in aperture-priority mode for the majority of the time.

manual01dmanual01aThe difference between manual and the semi-automatic modes (aperture-priority and shutter-priority) is that the latter balances the exposure for you by taking control of one of the three exposure variables. In other words, in shutter-priority, you control shutter speed and ISO, and the camera balances the exposure with the correct aperture. This tends to be a faster way of working, and you can easily use exposure compensation to brighten or darken the shot if desired. You also don’t need to worry about tending to your settings every time you recompose slightly – the camera will make sure your exposure is always correct, even if the light intensity changes. However, unlike in manual, the camera will judge the exposure every time you press the shutter, which isn’t always ideal. Below are three shooting situations when manual is the best option. Or, if you feel more comfortable working in a different mode, stick to it.
