The Week in Camera News

By , 25 September, 2011, No Comment

The Week in Camera NewsIt ‘really just a story dominated headlines this week in camera, Nikon has launched a compact camera system.

A Nikon CSC was scheduled for the month and on Wednesday, the company finally delivered with the V1 and J1.

TechRadar attended the launch in the UK of the new camera so we can spend some time learning about this new offering, which doubles Nikon “advanced camera lens interchangeable.”

Nikon offer more sophisticated two V1 is a high-resolution electronic viewfinder. J1 is aimed at families and novice photographers, wants to improve image quality. Confused about the differences? View cost vs. Nikon J1 V1 comparison of a piece.

Of course, the big question on everyone’s lips is how much the new cameras. Let him get a full review as soon as possible, but for now see Nikon’s hands and the hands V1 review on the Nikon D1 review of our first impressions.

As if this were not enough, we also set up a practice Nikon D1 V1 and video review.

Even if Nikon wants to distance himself from a compact system with the new class name ACILIA camera class, it is inevitable, of course, that is compared with the likes of Olympus, Sony DSLR, Samsung and Panasonic, the NX-G Series .

We also have two cameras Nikon SLR Compact V1 recent statistics to see how it stacks up, read the V1 vs. Nikon Olympus DSLR E-P3-7 vs. man to man to see who comes out on top.

Finally, in our Nikontastic raid this week, Nikon showed professional “Nikon 1″ is not out of question. Speaking exclusively to TechRadar, Simon Iddon confirmed that it is considered a professional model, if the feedback indicates that customers want. Read the rest of the interview to learn more about the future of a Nikon.

That’s all this week, tune in next week to add new publications, the latest technology of the camera, and news.

R?sultats vont de bruit et dynamique expliqu

By , 25 September, 2011, No Comment

Bruit et dynamique cadre rangeAs de notre processus de test cam?ra nous tirons un tableau qui nous permet de mesurer la dynamique d’une cam?ra et de la quantit? de bruit qu’il produit. Plage dynamique d’un appareil photo est une mesure de sa capacit? ? enregistrer des niveaux de luminosit? diff?rents au sein de la m?me image. Un appareil photo avec une grande gamme dynamique (DR), par exemple, peut enregistrer des d?tails tels que les nuages ??brillants ainsi l’herbe dans un paysage. Les nuages ??seront ?puis?s d’un uniforme blanc par une cam?ra avec une gamme dynamique faible. Le bruit est la mouchetures de couleur (le bruit de chrominance) et des marbrures claires et sombres (le bruit de luminance) qui peut ?tre vu dans certaines images. Le bruit devient plus visible quand haute sensibilit? (ISO) param?tres sont utilis?s ou les images sont souffl?es ? faire des grands tirages. Le chartWe fusiller nos bruit et plage dynamique tableau ? chaque sensibilit? (ISO) de r?glage disponibles et d’analyser les images en utilisant le logiciel DxO Analyzser. Le logiciel mesure le signal et le bruit qui rend l’image et lui donne un rapport signal sur bruit (SNR) de valeur. Le sup?rieur de la lecture SNR, le nettoyeur du signal d’image et de r?duire le bruit de la valeur. Un SNR ?lev? est g?n?ralement pr?f?rable ? un faible RSB. Cependant, un SNR ?lev? ? des sensibilit?s ?lev?es peuvent ?tre attribu?s ? un certain temps dans l’appareil de r?duction de bruit et de lissage de l’image, qui peut d?truire en d?tail. Notre tableau de bruit et plage dynamique, est fourni par DXO et elle est compos?e d’une s?rie de filtres en verre optique pur avec une gamme de densit?s neutres mont? dans une plaque de plastique ?pais. Le tableau est organis? sur une bo?te ? lumi?re sp?cialement fait qui produit diffuse un ?clairage uniforme. L’utilisation d’un verre de probl?mes cibles d’?clairage et d’?viter les incoh?rences qui sont souvent associ?s ? des cartes imprim?es pour l’?valuation de la plage dynamique. Le verre supprime ainsi la question de la texture du support qui peut cr?er des probl?mes de bruit pour une mesure pr?cise des cibles imprim?es. Notre laboratoire d’essais est mis en place suivant les directives de DxO et des images de la carte sont ?valu?s en utilisant le logiciel DxO Analyzer pour g?n?rer rapport signal sur bruit (SNR) et des valeurs dans une plage dynamique large d’une cam?ra de sensibilit? compl?te – pour les images RAW et JPEG. Si le logiciel n’est pas compatible avec les fichiers RAW d’un appareil photo, nous les convertir au format TIFF et analyser ces images. Nous avons seulement comparer des fichiers du m?me format, JPEG avec JPEG, TIFF et RAW avec des mati?res premi?res avec le TIFF. Suivez les liens pour plus d’informations sur DxO Analyzser

Nokia 701 cell phone smallest, loudest voice and brightest screen

By , 25 September, 2011, No Comment

Nokia to launch new smartphone in the world with loud, bright and small recently.
nokia-701
Nokia 701 is the brightest smartphone on the market – with 1000 nits of luminance equivalent to 3145 lux, but it does mean – as you might be drawn to conclude – that the screen is three times brighter than a TV studio ? And the Nokia 600 is the most powerful, blasting 106 PHONS through its speaker, which is as loud as standing next to a lawn mower. Right?

Light Metering (or volume) is not simple. Because they are actions that depend on more than one thing – and there is this-people-make-over that way, too.

Nits measure light in a manner very different from what we are used to power the choice of a light bulb to begin with. Nit salt comes from Latin, to shine. Capable of slowing depends on the brightness (the amount of things that throws light), the solid angle it radiates from the surface and the source. For example, laptop screens are designed to have a constant “nittage” in a large solid angle (as it would be strange and irritating if the brightness varies from one place to another or a dependent of the angle-).

Lux, on the other, depending on the brightness and the surface of the source, and you’ll often through it, if you buy a video camera, they often contain a minimum level of light in lux. A camera with good low light capabilities will have a lower ranking lux. The angle does not matter because you will be pointing in the right direction, is not it?

If you are old school and as the light in non-metric units, can also be measured in Lamberts Skot or brilliant.

All clear?

It is luminance, but you know how loud the sound is phons?

The phones are a different animal decibels, which is quite an unnecessary step when it comes to “strong” sounds something.

You can play two different sounds of 60 decibels and sounds different – quieter and stronger – because the two sounds that have the same intensity that really is not that they have the same volume. Upon hearing the man also depends on the frequency of sound, to get the phone you need to track what is called a curve of equal intensity. Complex sounds can be measured in relation to the test tones of 1000 Hz, and 60 media phones as loud as a tone of 60 dB, 1000 Hz

Nokia 600 is high enough in a normal environment, absolutely. But next to a chainsaw or a lawnmower, you will always get away, we are afraid. But hey – combined with a Nokia headset Essence and 99.8 percent noise reduction – yes, let’s just say that we look forward to your reports …
