Ultra B Images

[Quincey Homer]

My cameras are how 1 at a time loosing the normal video and showing pink and green images with lines across them. Support says to delete, power off, reboot base and add back. Anyone else having this problem? I have to do this once a week.

I might tend to think it's a signal strength/quality issue. Try moving a camera closer to the hub for testing and see if that helps. You could also move the hub closer to the cameras or at least to one camera.

It packs a main image sensor that's much bigger than those found on the iPhone 15 Pro Max or Galaxy S24 Ultra, which together with a wide, variable aperture and Leica-engineered optics, allows this phone to take some of the best images I've ever taken on a phone.

I do a lot of street photography, usually in black and white, and I loved using the Xiaomi phone just as I would my usual camera. It locks focus quickly and lets me capture moments before they pass me by.

I didn't use the zoom lens here, but instead cropped in later on the main lens to focus the scene on this person carrying flowers. Despite cropping into only a small portion of the full image, there's still loads of detail.

But again I prefer switching to pro mode and going with a black and white look. By stopping the aperture down to around f/3, the phone has been able to capture these starbursts around the lights, which is something I've only ever been able to achieve on a regular camera with a lens set to around f/11.

But a bit of time in Lightroom and I've been able to transform it, brighting the scene and adjusting the color balance overall. I'm so impressed at how much information is contained in the raw files -- I can edit them in just the same way I would with shots form my regular camera, without worrying about losing information.

Subsequent deep imagery from Hubble, including the Hubble Ultra Deep Field, has revealed the most distant galaxies ever observed. Because of the time it has taken their light to reach us, we see some of these galaxies as they were just half a billion years after the Big Bang.

Deep field observations are long-lasting observations of a particular region of the sky intended to reveal faint objects by collecting the light from them for an appropriately long time. The 'deeper' the observation is (i.e. longer exposure time), the fainter are the objects that become visible on the images. Astronomical objects can either look faint because their natural brightness is low, or because of their distance. In the case of the Hubble Deep and Ultra Deep Fields, it is the extreme distances involved which make them faint, and hence make observations challenging.

Using the different Hubble Deep fields astronomers were able to study young galaxies in the early Universe and the most distant primeval galaxies. The different deep fields are also a good gathering grounds to find the most distant objects ever observed.

The idea for the Hubble Deep Fields originated in results from the first deep images taken after the repair in 1993. These images showed many galaxies, which were often quite unlike those we see in the local Universe and could not otherwise be studied using conventional ground-based telescopes. The first Deep Field, the Hubble Deep Field North (HDF-N), was observed over 10 consecutive days during Christmas 1995. The resulting image consisted of 342 separate exposures, with a total exposure time of more than 100 hours, compared with typical Hubble exposures of a few hours. The observed region of sky in Ursa Major was carefully selected to be as empty as possible so that Hubble would look far beyond the stars of our own Milky Way and out past nearby galaxies.

In 1996 it was decided to observe a second Deep Field, the Hubble Deep Field South (HDF-S), to assess whether the HDF-N was indeed a special area and thus not representative of the Universe as a whole. This time the field also contained a quasar, which was used as a cosmological lighthouse and provided valuable information about the matter between the quasar and the Earth.

"In my view the Hubble Deep Fields are some of the images that have made the greatest impact on observational cosmology so far. These impressive dips into the depths of space and time have allowed astronomers to glimpse the first steps of galaxy formation more than 10 billion years ago and are without doubt some of the great legacies of the Hubble Space Telescope."

After the Hubble observations of HDF-N and -S, other ground and space-based instruments targeted the same patches of sky for long periods. Some of the most interesting results seem to emerge from these fruitful synergies between instruments of different sizes, in different environments and with sensitivity to different wavelengths.

The Hubble Ultra Deep Field from 2004 represents the deepest portrait of the visible universe ever achieved by humankind. Using the improved capabilities of the Advanced Camera for Surveys, the camera installed during the 2002 servicing mission, a new Deep Field was observed, in the constellation of Fornax (the Furnace).

Using NICMOS, its first near infrared camera, Hubble made infrared observations of the original Hubble Deep Field, the Hubble Deep Field South and Hubble Ultra Deep Field. These images revealed more distant objects, though the picture quality achieved by this instrument could not compete with optical images.

The next breakthrough came after the 2009 servicing mission in which astronauts installed a new instrument capable of making greatly improved infrared observations. The resulting image, covering most of the field of view of the 2004 Ultra Deep Field observations, is the deepest ever made of the cosmos. It is unlikely to be surpassed until the NASA/ESA/CSA James Webb Space Telescope is operational, later this decade.

The 2009 infrared image of the Hubble Ultra Deep Field has been an extremely fertile hunting ground for scientists who study the early Universe. Several candidates for the most distant galaxy ever observed have been spotted in this image.

The last Hubble Ultra Deep Field released in 2014 was observed in ultraviolet. This image allowed astronomers to study star formation in a region 5 to 10 billion light-years away from us. The study is called the Ultraviolet Coverage of the Hubble Ultra Deep Field (UVUDF) project. The addition of ultraviolet data to the Hubble Ultra Deep Field using Hubble's Wide Field Camera 3 gives astronomers access to direct observations of regions of unobscured star formation and may help to fully understand how stars formed.

The Hubble Frontier Fields is a three-year, 840-orbit programme which created the deepest views of the Universe to date, combining the power of Hubble with the gravitational amplification of light around six different galaxy clusters to explore more distant regions of space than could otherwise be seen. These observations are helping astronomers understand how stars and galaxies emerged out of the dark ages of the Universe, when space was dark, opaque, and filled with hydrogen. In analysing how the light of more distant galaxies is bent by the cluster astronomers also learn about the distribution of normal matter and dark matter within such clusters.

Each year, SNMMI chooses an image that best exemplifies the most promising advances in the field of nuclear medicine and molecular imaging. The state-of-the-art technologies captured in these images demonstrate the capacity to improve patient care by detecting disease, aiding diagnosis, improving clinical confidence, and providing a means of selecting appropriate treatments. This year, the SNMMI Image of the Year was chosen from more than 1,500 abstracts submitted for the meeting.

The image quality of PET systems has improved in recent years, mostly by increases in sensitivity, including enhanced time-of-flight capabilities. However, these systems have shown only minimal improvement in intrinsic resolution. To address these issues, researchers designed the NeuroEXPLORER PET scanner with a focus on ultra-high sensitivity and resolution, as well as continuous head motion correction.

In the study, researchers conducted human brain imaging with both the NeuroEXPLORER and the High Resolution Research Tomograph, or HRRT (the previous state-of-the-art imaging tool). Multiple targeted radiopharmaceuticals were administered to observe synaptic density, dopamine receptors and transporters, muscarinic cholinergic receptors, and glutamate receptors. Images from both scanners were then compared.

A striking improvement in image contrast and quality of the NeuroEXPLORER compared to the HRRT was evident. NeuroEXPLORER images demonstrated low noise and exquisite resolution, showing focal uptake in specific brain nuclei.

The NeuroEXPLORER scanner was built as a collaboration with Yale University, University of California, Davis, and United Imaging Healthcare of America, and was funded by a National Institutes of Health Brain Initiative grant. While the NeuroEXPLORER is currently used for research purposes, Carson and colleagues hope that once the excellent image quality is recognized by physicians it will become available for clinical use.
