This will show the currently selected collection of images and doesn’t require rendered previews. If you already have your images inside Capture One and wish to take advantage of the culling features, you can open the Cull view, available in the toolbar next to Import and Export. Previous versions of Capture One would not remember the selection if the Importer was closed. When rating and tagging images, Capture One will store the metadata temporarily if you decide to finish the culling session later. Browse with zero delay, group images together by similarity, star rate and color tag, zoom to 100% to evaluate sharpness, filter based on different metadata, and change the timestamp of images to ensure correct chronological order – all before importing your images into Capture One.

Important: The first version of Smart Adjustments relies on faces, both for the reference and the images being adjusted. You can, for example, make a Smart version of your most used Style by including Smart Adjustments when re-saving it, or save a Smart Style which only corrects White Balance for faster portrait editing. Smart Adjustments are not supported on Layers. They can be applied to batches of images, during import etc. This type of Style can include regular adjustments which allows turning any Style into a Smart Style which automatically sets the White Balance and/or Exposure to achieve consistency. Smart Adjustment references can be saved into a Style for continuous use ( Smart Style).The Smart Adjustments Tool is in the Adjust tab of the default workspace. This reference can then be batch applied to other images which will have White Balance and/or Exposure adjusted automatically to match the look of the reference. Using the Smart Adjustments Tool, you can set a reference from an image with a visible face that has the desired White Balance and Exposure.Smart Adjustments can be used in two ways: The first version of Smart Adjustments is designed for photographers shooting portraits, weddings, events, and other images of people. Smart Adjustments can be added in a Style where additional adjustments can be included as well, getting closer to one-click editing. The Smart Adjustments Tool is designed for editing workflows where copy/apply cannot give a consistent result because the starting points are different. ![]() Automatically adjust Exposure and White Balance to match the look across images, heavily reducing the need for manual editing.

And unlike with the previous vendor’s ADC solutions, we are confident the F5 systems will perform as advertised.” Superior uptime “We can plan much more easily now because we can scale within the VIPRION chassis itself. “With VIPRION, we can deploy the same ADCs and architecture for years to come, despite tremendous projected growth,” says Kelty. The F5 VIPRION solution enables Pandora to continue to scale smoothly for years without having to replace its current load balancing devices. As a result, Pandora could serve its more than 62 million and growing numbers of users with consistent, top-notch performance. These delivered smooth application performance and presented no performance hotspots or bottlenecks. With its original BIG-IP systems, Pandora was able to create load balancing pools of up to 100 or more application server nodes. Superior scalability with smooth, consistent performance Benefitsįrom both its original F5 BIG-IP systems and the recent F5 VIPRION upgrade, Pandora realized several benefits, including superior scalability, performance, and uptime, as well as enhanced user satisfaction. Pandora also decided to deploy two pairs of F5 BIG-IP Global Traffic Manager (GTM) devices in its West Coast and East Coast data centers to ensure users would experience superior streaming audio performance. “We were able to start with a single pair of VIPRION chassis, with a single blade in each, and will be able to add up to three more blades as traffic needs dictate.” The F5 ScaleN architecture of VIPRION allows organizations to start with a single ADC blade and scale as required by adding blades. Instead of forcing organizations to replace the entire ADC unit or purchase additional units when traffic volume surpasses its capabilities, the VIPRION solution provides application delivery in a blade server chassis configuration. “Our growth accelerated so fast that, last year, we felt it was time to upgrade to a solution that would allow us to add a lot more capacity without having to upgrade the entire device.” This led Pandora to F5 VIPRION. Pandora started with two pairs of BIG-IP 6400 devices, which it upgraded to BIG-IP 8900 devices a few years later. “F5’s implementation was very quick, thanks to a knowledgeable engineering group that could answer all our questions on the spot, and the solution outperformed all the others we tested,” he says. F5 BIG-IP systems won hands down, according to Kelty. In 2007, Pandora considered several replacement ADC solutions and ran pilot testing on three. In 2012, Pandora decided its projected growth required another ADC upgrade, with even more massive scalability than it had needed in the past. The result was a transition to F5 BIG-IP systems in 2007, which lasted Pandora through five years of enormous growth. “We needed a solution capable of handling 100 application server nodes or more in a single pool without any performance bottlenecks.”įinally, Pandora was looking for a product that could manage SSL offload at a future date. “We needed a solution that would do what the vendor promised, with a solid code base that wouldn’t force us to devise all kinds of tweaks, scripts, and workarounds,” says Kelty. When the two failover ADC units proved incapable of handling Pandora’s traffic volume, leading to significant downtime, Pandora decided it was time for a change. “We needed 14 ADC units in one data center-including 2 for failover-just for audio delivery.” Pandora’s ADC solution also required its already overextended engineering team to create and implement manual tweaks and workarounds just to allow application server nodes to be taken down for servicing and updates. “Our ADC solution was just not living up to the vendor’s promises,” says Kelty. However, the solution wasn’t meeting Pandora’s scalability and performance needs. “We have to be sure we can always handle the next wave of users and user traffic six months down the road.”įive years ago, Pandora was using a different Application Delivery Controller (ADC) to distribute user application requests to a data center farm of music delivery servers. “Since we’re an Internet radio service, we want users to have the best possible listening experience with no delays or outages,” says James Kelty, Director of Network Engineering for Pandora. With listeners tuning in for more than a billion hours per month, Pandora must always be ready to handle massive amounts of traffic with top-level performance. ![]() ![]() Launched in 2005, Pandora is the leading Internet radio service, streaming personalized music and comedy to tens of millions of listeners worldwide based on each user’s individual preferences.

He said making the match between families and homeowners can be challenging. Officials hoped it would help empty the Expo and provide people staying there with a place to go.īrit Vitalius, president of the board of directors for the Quality Housing Coalition, said Friday that there has been only one successful placement in the home share program so far, though the coalition has about 30 other leads it is exploring. The city, Quality Housing Coalition and Greater Portland Council of Governments last month launched a home share program aimed at connecting tenants, including asylum seekers, with landlords and homeowners with extra space in apartments, homes and short-term rentals. The announcement comes as the city and community groups have been scrambling to find new housing for families at the Expo, some of whom already have been moved to other options, including spaces that have opened up at the city’s family shelter and a motel in Portland that accepts General Assistance. ![]() In the meantime, Grondin said staff were planning to let families at the Expo know about the plans Friday afternoon and that the city was in the process of informing community organizations, which are expected to help provide support services at the hotels.ĭetails on transportation and how the families will be moved to the hotels are being worked out, she said. The contracts don’t require City Council approval, but the council is expected to receive an update on the plans at its meeting Monday. The city expects its share of the cost for the hotels to be around $500,000, Grondin said. The state reimburses the city for 70% of General Assistance costs, which would be used to pay for the hotels, while the city is responsible for 30%. The city is hoping to use one of the hotels for a few months, while the second one could be used for up to a year, she said. “We’ve had pretty good success finding housing placements, so we don’t anticipate having to use the hotels for very long, but obviously we need something in the interim,” Grondin said. A total of 192 people are currently staying at the Expo, down from around 300 this spring. 1, overwhelming already strained shelter and housing resources. More than 1,600 asylum seekers have arrived in Portland since Jan. ![]() The city set the closure date weeks ago and stopped accepting new families at the Expo in early June, saying it would need to reopen the sports arena for scheduled events this fall. The temporary shelter at the Expo, which opened in April to house an influx of asylum seekers, is scheduled to close Wednesday. Grondin said she did not want to disclose the locations until the documents were signed so as not to jeopardize the negotiations. The contracts for the two hotels, both of which are located in the greater metro area outside Portland, were expected to be signed later Friday. “We want to have a few more months to find them housing placements or work them into the existing system, such as units that may open up at the family shelter,” city spokesperson Jessica Grondin said Friday afternoon.

The responder performs the same calculation and confirms the hash is correct. In packet #5 the Initiator sends a hash generated using pre-shared key set as key material so that only those who possess pre-master key can do it: In our case, this is done via pre-shared keys: If it is RSA certificate then peers exchange RSA certificates and assuming the CA that signed each side is trusted then verification complete successfully. If we said we're going to do this using pre-shared keys then verification consists of checking whether both sides has the same pre-shared key. The purpose of this exchange is to confirm each other's identity.
