BLUE PLANET 2 REVIEW: 4K AND HDR AT THE HIGHEST LEVELS

In 2001 the BBC released the documentary series The Blue Planet , which featured marine environments like never before. During the shoot, which lasted about 5 years, creatures and habitats never immortalized by a video camera were filmed, all told by Sir's voice. David Attenborough , probably the most important science communicator in the world. techiescity

The series was a success, so much so that in 2017 its sequel, Blue Planet 2, came out on home video in 2018 and now also available in Italy thanks to Koch Media, who edited the local edition of this titanic documentary. It took four years of filmingfor the making of this sequel, which sees the return of Sir. David Attenborough, voiced in Italian by the warm voice of Dario Penne.

In search of perfection

Blue Planet 2 is one of the best Ultra HD Blu-Ray we've ever seen. We do not say it lightly, but everything, from the packaging to the image quality, to the audio, has been thought with almost maniacal care. The Italian edition is sold in a recycled cardboard sales pack, which contains three Ultra HD Blu-Ray and three Blu-Ray, as well as a 24-page booklet and seven postcards with images of the most significant animals shown during the program, also printed on FSC-certified paper. The sales pack is 100% eco-sustainable, a choice perfectly in line with the Blue Planet 2 philosophy. Interesting information contained in the booklet, which explains not only the environments in which the filming was made, but also the cutting-edge technologies used to capture the incredible images immortalized during the seven episodes in which the documentary is divided.

Blue Planet 2 was shot entirely with 4K cameras, from which a 4K master was created. This base, qualitatively excellent, was then used for the realization of the Ultra HD Blu-Ray, with an aspect ratio of 1.78: 1, 10-bit color depth and HDR. There is no Dolby Vision nor HDR10 +, which would have given a further boost to visual quality, but in this case you don't really feel the need.

The work done on the audio is also excellent, the Italian localization takes up the DTS-HD Master of the original track , adding the always pleasant voice of Dario Penne, a veteran of dubbing who over time has given the voice to actors of the caliber of Anthony Hopkins and Michael Caine, and whose vocal timbre marries beautifully with the unique images captured by Blue Planet 2's cameras.

A feast for the eyes

We saw Blue Planet 2 on a 65-inch Sony AG9, one of the best OLED TVs available today, which in some scenes showed the full merits of this technology. Observing the bioluminescence of the marine depths really leaves you speechless , the credit goes both to the television, which best shows the high-contrast scenes, where small scraps of light meet the deepest darkness, and to the very high quality of the shots taken for Blue Planet 2. Many are convinced that 4K does not give a qualitative boost in weight compared to Full HD, but it all depends on the source used and how this is shot and then poured onto the physical medium.

In the case of Blue Planet 2 the detachment from the Blu Ray version is obvious, the details that can be observed really do justice to this format.

From corals to the smallest marine creatures, to large ocean predators, you are left speechless in front of some images. Color also makes a fundamental contribution to visual quality, HDR and the extended color space offer a representation of marine environments that fully satisfies the view, without color banding or artifacts to ruin the rendering.

Even on the audio front, the quality is very high , but given the type of content and the visual wonder it can offer, it almost takes a back seat. The channels are well separated and the narrator is always clear, the surround sound is not very evident but it is certainly not a content to be watched at high volume, it is the images and the voice of Sir. David Attenborough to take over on this journey into the deep sea. Journey that culminates with a very interesting extra, the making of the series, which reveals the secrets behind the filming of Blue Planet 2.

TP-LINK ARCHER MR600 REVIEW: A GREAT 4G + AND WI-FI ROUTER

Image
" The Italian connections are not the best ". We have all been repeating this for a long time now and we know well how many areas of Italy still navigate through the now obsolete 7 Mega ADSL, or even worse. Over the years, the most disparate solutions have been sought to solve the coverage problems of the most remote areas, but a stable solution has hardly  techsupportreviews    been found. However, a recent TIM report shows that 99% of the Italian population lives in an area covered by the LTE network(4G and 4G Plus). Despite the clear problems in terms of latency, which do not allow some operations such as gaming to be carried out in the best possible way, the cellular network is a consolidated reality in our country and in many areas it can guarantee much higher speeds than the traditional cable connection. In short, in some cases a router with support for 4G + SIM cards becomes indispensable. For this reason, TP-Link has created Archer MR600, currently sold on Amazo...
