Post-focusing of Panasonic cameras

05.01.2016

Panasonic has released a new firmware version for three Lumix cameras with a post-focus function. With this feature, the cameras take up to 49 photos simultaneously with a slightly shifted point of focus. All photos are saved in one file. The essence of the new function is that with its help the depth of field of the image can be changed manually after shooting.

The post-focus firmware for Panasonic Lumix GX8, Lumix G70 and Lumix FZ300 can be downloaded free of charge. The manufacturers promised to release firmware for the Panasonic Lumix GH4 camera soon. We have already tested the new firmware and believe that it lacks only two little things.

Panasonic's post-focus feature is a bit like Lytro's revolutionary light field technology: you first take a picture as usual, and only then set the focus area. This feature is still a delight. All the more so for owners of the Lumix GX8, G70, FZ300, and soon the Lumix GH4, for whom this magical option is now available for free.

Instead of light field technology, Panasonic uses its 4K photo mode. Of course, you remember that Ultra-HD video means, in the language of photographers, continuous shooting at 30 frames per second at 8 megapixels each and an almost unlimited number of shots in the series.

Pictures for subsequent post-focusing are only 8 megapixels. But I must say, this is enough to print photos up to A3 inclusive. All 49 shots are stored on the memory card at the same speed as one: the whole shooting process consists of a couple of steps: take a picture, indicate on the touch screen where the focus point will be and save the photo in JPEG format.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Li-ion battery with water instead of electrolyte 13.12.2021

Researchers at the Yokohama National University of Japan have created a prototype lithium-ion battery with metastable and nanosized oxides based on molybdenum, which uses water as an electrolyte solution. This prototype is durable, fast-charging, and non-flammable.

Also, the test sample of the battery has "better ionic conductivity, environmental friendliness and high safety" compared to conventional ones. Even after 2 charge-discharge cycles, its capacity dropped by less than 30%.

The work of Japanese researchers paves the way for the development of high-energy, durable and safe batteries. But the main disadvantages of the latter are a low level of productivity and the possibility of using only under low voltage conditions, since water is destroyed at a high voltage level.

The specific gravity of energy (performance indicator) - a "water" battery is about half that of a conventional one. Therefore, for the production of batteries, a larger case size would have to be used.

"We have a safer battery with a long life that is expected to be used in practice, although the voltage is slightly lower [than required for commercial devices]," said Naoaki Yabuuchi, professor of chemistry at Yokohama National University.

Japanese researchers believe that their development may well be put into production within three years and even find application - for the accumulation of solar and wind energy, as well as in electric vehicles with a short range.
