Fuji X10 First Impressions While Kodak lost the plot a long time ago, Fujifilm in recent years has continued to produce some very nice small-sensor cameras. But its DSLR sourcing relationship with Nikon evaporated some five years ago leaving a vacuum for the company at the high end of the market. Then last year they released the X-100, and all of sudden Fuji seemed to get their mojo back. The X-100 has been a huge hit for them. Reading and Waiting. FujiFilm X10 @ ISO 400 There's No Free Lunch Camera design is the art of compromise. Sadly, the laws of physics get in the way of our fantasies. That's why there are so many different camera models.

6 Essential Tips for DSLR Video The following two tabs change content below. Photographer who loves challenging and experimental photography and is not afraid to share the knowledge about it. Nowadays, it seems that the majority of DSLR, mirrorless, and even point-and-shoot cameras have video features. Of course, if your camera has video capabilities, you want to know how to make the most of it. Photo by Sebastiaan ter Burg The exposure concept is the same: you control the ISO, aperture, and shutter speed with small exceptions. Shutter Speed The shutter speed is what makes the difference between a jittery and a smooth image. Photo by Mariano Kamp For video to look smooth at a given frame rate certain shutter speeds must be maintained so that the motion is smooth. You can intentionally shift to shorter or longer shutter speeds to achieve certain effects, but in order for it to look good, it has to be done properly.

Camera Size - Digital Camera Size Comparison Tool Sydney Home – Heidi Dokulil and Richard Peters The Sydney home of Heidi Dokulil and Richard Peters – architectural perfection! (…and that couch ain’t bad either). All photos – Lucy Feagins/The Design Files. Designer details – love love love that ENORMOUS Akari paper pendant lamp by Isamu Noguchi and amazing green dining chairs by Vico Magistretti / Artemide. Who needs bookshelves when a few vertical stacks of books look this good? Eames LCW Plywood chair in RED. Homes just don’t get more photogenic than this. It’ll be no surprise to learn that this incredible home belongs to two super creative Sydney folk. Whilst the open plan living and pitched roof give it a spacious feel, this perfect pad is actually deceptively tiny – just 85m2, with one modest master bedroom and an even smaller study. Whilst the architectural elements and Japanese proportions are a large part of this home’s appeal – it sure helps when you’ve got the coolest furniture in Sydney.

The D-Photo | Photography inspiration & articles | Camera gear | post processing - Part 2 Amazing film photography by Owen Luther "An amateur from southeastern Pennsylvania who prefers to shoot with film over digital. I do own and occasionally shoot with a DSLR, however it has seen very limited use since dusting off my 35mm and acquiring a medium format system just under two years ago. Aside from slowing the entire photographic process down which generally speaking results in better photography anyway, I prefer the tangible nature of film photography and all that comes along with it." ~ Owen Luther For more amazing film photography by Owen Luther, you can visit his flickr...

Technique - essais, objectifs, macrophoto, macrophotographie, photographie, macro, tubes allonges, bonnettes, flash, diffuseur, retouches, capteur, CCD, CMOS... Les objectifs macro moderne autorisent une mise au point continue de l’infini au rapport 1/1, ce qui donne un confort d'emploi remarquable ! La formule optique de ce type d'objectif est étudiée pour obtenir une excellente homogénéité de l'image à tous les rapports de grandissement tout en minimisant les "déperditions" de lumière notamment grâce à un système de mise au point interne qui évite l'allongement du tirage. Evidemment, le prix d'un objectif macro est plus élevé qu'une focale fixe mais les performances optiques sont généralement d'un haut niveau et il peut remplacer, sans aucun problème, un objectif de focale équivalente !!! Un autre point à ne pas négliger lors du choix d'un objectif macro est de savoir si la focalisation (mise au point) est interne (IF pour "internal focus") car dans ce cas, la taille de l'objectif reste la même quel que soit le rapport de grandissement et c'est un gros avantage par rapport à un optique non IF. Inconvénients : un seul et unique...le prix.

Fuji X10 Photography by Jim Radcliffe My Photography with the Fuji X10Jim Radcliffe This Is More Like It I was so disappointed by Panasonic's GX1 that buying the Fuji X10 was somewhat of a no-brainer. It's quite obvious that Fuji, unlike Panasonic, has been listening to their customers and produced a compact camera a that ticks a lot of check boxes for those who want a "rangefinder style" compact camera rather than a Mini-DSLR type camera. They gave it a fast lens, an optical viewfinder, manual controls and a retro look that is sure to appeal to many. The Fuji X10 appeals to me on a number of levels. Pros It's small It feels good in the hand Control knobs stay where you put them. Cons It's small.. some would say too small Optical Viewfinder displays no info whatsoever AF sometimes indicates focus lock but the image is OOF 40mm filter size.. not readily available Proprietary RAW file format No delete button on the back of the camera Correction: It does have a delete button but not a dedicated delete button. So what?
