Instagram ‘Focus’ mode brings fake bokeh to single-camera smartphones

11 Apr

Instagram has released version 39 of its iOS and Android mobile apps, and the update brings with it a background-blurring portrait mode similar to the “Portrait”, “Depth” and “Bokeh” modes we have seen on most recent high-end smartphones… with one major twist.

While the baked-in bokeh modes on most smartphones use the slightly offset lenses of a dual-camera setup, or other partly hardware-based methods to create the effect, Instagram’s version appears to solely rely on face detection. That means you shouldn’t expect perfect subject/background isolation and super-smooth blur transitions, but it also means single-camera phones can take advantage of the feature.

Focus mode is available in the Stories camera UI, right next to “Superzoom”. It works with both front and rear cameras, automatically blurring the background when one or more faces are detected. Focus mode works on the Apple iPhones SE as well as the 6S, 7 and 8 generations and the iPhone X. It is also available on “select Android devices”, which appears to include most current high-end Androids.

In short: Focus mode looks like a nice addition to the Instagram feature set, but if your smartphone offers a native portrait mode you’re probably better off using that and inserting the image into Instagram via the gallery or camera roll. To find out more about Focus, head over to the Instagram Press blog or update the app and give the feature a try for yourself.

PolarPro has also released a pair of Kanga Camera Filter Cases to keep either three or six filters safe and sound when traveling. They feature a soft microfiber lining and a magnetic opening for quick and quiet access. Like PolarPro’s filters, these come with a lifetime warranty.

PolarPro’s QuartzLine filters start at $ 60 and go up to $ 250, depending on the size and filter style. The three- and six-filter Kanga Camera Filter Cases retail for $ 40 and $ 50, respectively. You can find the full lineup of filters and cases on PolarPro’s website.

Press Release

PolarPro Leaps into Professional Lens Filter Market with Launch of QuartzLine Filters

PolarPro, long-trusted for its high-quality action camera and drone lens filters will bring new industry-leading glass to professional photographers and cinematographers with the full frame QuartzLine Filters.

Costa Mesa, C.A. – April 9, 2018 – PolarPro, developer of products inspired by adventure, announced today it is expanding its line of lens filters to professional photography and cinematography cameras. Well known for its industry-leading action camera and drone filters, PolarPro is continuing its tradition of quality with the new professional-focused QuartzLine Camera Filters for DSLRs, mirrorless and cinema cameras. The QuartzLine Filters range from $ 59.99 to $ 249.99 depending on size and filter style, for more information and specific pricing on the new PolarPro QuartzLine Lens Filters, please visit us here.

Constructed of 99.9% pure fused quartz, the QuartzLine Filters set a new bar for light transmission and purity as the rare, fused quartz element delivers an extremely low refractive index compared to traditional filters. A new optical coating method reduces surface reflectivity to less than one percent and increases surface hardness, all while maintaining a perfectly neutral color profile. The QuartzLine Filters will offer circular threaded UV, polarizers and neutral density filters from ND8 to ND100K, as well as hybrid single element ND/polarizing lens filters ranging from ND4/PL to ND1000/PL. With the filters running from 37mm, 46mm, 67mm, 72mm and 82mm, and an optional assortment of step-up rings, these stunning new optics will help adventure seeking creators capture perfection. All QuartzLine Filters can also be paired with PolarPro’s rugged construction Kanga Camera Filter Case to ensure they can go anywhere.

“As we have worked to establish PolarPro as the preferred option for drone cinematographers, we’ve also been working behind the scenes to make the QuartzLine Filters into an extremely precise and consistent filter for professional photo and video creators,” said Austen Butler, Co-Founder of PolarPro. “With QuartzLine, we wanted to create a rugged camera filter in line with our obsession over image quality. After testing 29 different materials we landed on a fused quartz glass element, with hyper neutral coatings to reduce reflectivity, increase scratch resistance, and most importantly, delivery a consistently neutral color profile.”

Ideal for professional photographers and cinematographers looking to ensure the most accurate representations of their creative vision, the QuartzLine Camera Filters combine PolarPro’s Death Valley-tested precision coatings with some of the most premium materials available.

Fused Quartz Glass At 99.9% pure, fused quartz is one of the purest glasses available. It’s this purity that allows the QuartzLine Filters to be extremely durable while delivering stunning optics and optimal clarity. The fused quartz glass also helps to ensure QuartzLine Filters have an extremely low refractive index of only 1.46 giving the filters increased stability and temperature resistance (from -50F up to 130F), so content creators can bring the true-life colors to their final product from the most extreme locations on the planet.

Color and Image Accuracy Light transmission in the QuartzLine Filters is perfectly neutral from the UV spectrum all the way across the IR spectrum, which gives photographers and cinematographers the confidence to stretch the boundaries of their creative vision while ensuring color and image accuracy. Unique among filter manufacturers, PolarPro leverages its new advanced coating technologies to eliminate any color cast or color inconsistency throughout the spectrum. The single-element QuartzLine Filters are available in a wide array of ND and ND/PL filters so photographers or cinematographers do not have to stack glass to achieve the desired effect, while also allowing wide-angle shots without fear of vignetting.

Precision Coatings The QuartzLine Filters rely on PolarPro’s advanced coating technologies to eliminate color shift, reduce flaring and ghosting, and to increase surface hardness for the already-durable fused quartz glass. Unlike other filters on the market, QuartzLine receives advanced coatings to eliminate color-casting or inconsistencies throughout the color spectrum. Each of the QuartzLine Filters feature:

Neutral Density Coating – Precisely applied to reduce the desired light transmission without incurring color shifts, PolarPro’s ND coatings have been tested in the most demanding conditions possible from the workshop test bench to sun-blasted skies around the world.

• Anti-Reflective Coating – Reducing the reflectivity of the lens filter eliminates hot spots in the frame, and PolarPro’s coating technology allows the 3.45% native reflectivity of the fused quartz to be reduced to a negligible 0.455%.

• Anti-Scratch Coating – Protecting the coatings and base glass while hardening the filters surface, PolarPro’s anti-scratch coating has stood up to the demands of the most adventurous downhill thrashings possible.

• Hydrophobic Coating – Increasing surface hardness, while making for easy cleaning and water resistance, PolarPro’s hydroscopic coating provides the external layer on the QuartzLine Filters.

Durable Brass Frames The durable four-part frame which houses each QuartzLine Filter has been over-engineered to ensure it threads onto each lens perfectly. Wanting to use the absolute best materials possible, PolarPro eschewed the traditional aluminum frames in favor of the more durable, yet lightweight, brass frames. With the unique production demands of professional photographers and videographers in mind, the QuartzLine showcases the brass exterior portion of the frame while the interior is coated in a matte back to prevent unwanted reflections.

Comprehensive Product Range The QuartzLine Filters will be available for a wide array of lens sizes and a series of optional step-up rings will allow QuartzLine to accommodate most professional lenses. The range of UV, circular polarizing filters, traditional neutral density and hybrid neutral density/polarizing filters is detailed in brief below, or on the QuartzLine product page, here.

  • Filter Thread Sizes: 37mm, 46mm, 67mm, 77mm, 82mm
  • Filter Options: UV, CP, ND8, ND8/PL, ND16, ND16/PL, ND64, ND64/PL, ND1000, ND1000/PL, ND100000
  • Step-up Ring Options:
    • Step 52mm, 55mm and 58mm lens to 67mm filter
    • Step 62mm, 67mm and 72mm to a 77mm filter
    • Step 62mm, 67mm, 72mm and 77mm lens to an 82mm filter
  • PolarPro Kanga Camera Filter Cases: Available in 3-filter or 6-filter storage sizes, the PolarPro Kanga Camera Filter Case features a magnetic opening for quick and easy filter access, plush microfiber interior lining, and a pull-tab system for streamlined filter selection. The PolarPro Kanga Cases retail for $ 39.99 and can be purchased here.

How to Add or Remove a Vignette Using Lightroom

11 Apr

You have likely seen photos on the internet which are well-exposed at the center, but the brightness starts reducing towards the edges. If you are not familiar with the name of this effect, it is called an edge vignette or image vignetting.

Interestingly, a vignette is an effect which occurs naturally but can also be achieved intentionally during the post-processing stage. Not everyone likes the vignetting effect in their photos, for some, it is a useful technique and for others, it is a disaster. Honestly, a well-done vignette can help draw viewer’s attention towards the subject placed in the center. You can use it to your benefit if you are a portrait, wildlife, or a wedding photographer.

How to Add or Remove a Vignette in Adobe Lightroom

But vignetting could also make your photos unappealing if you are a landscape, interior, or commercial photographer, as you would not want the edges of your photos to be too dark.

Causes of Vignetting

There are multiple reasons why the vignetting effect gets applied to your photos when using a digital camera. One of the main causes of vignetting is the use of wide aperture openings such as f/1.4 or f/1.8. But if you increase the aperture value by 2-3 stops, you can easily eliminate the vignetting effect in your photo.

Another cause of vignetting could be the use of a longer focal length, but as you go wider the effect starts getting less visible. Some low-end lenses are also more likely to have an edge vignette than their more expensive counterparts.

Using multiple lens filters or mounting low-quality lens filters can also result in strong vignetting, as they can block the amount of light entering through the lens from various angles. Did you know that even a third-party lens hood can result in a vignette? So make sure you buy the correct hood compatible with your lens to avoid any vignetting in your photos.

How to remove a Vignette using Lightroom

If your camera has captured a photo with the vignette effect due to one of the reasons mentioned above, you can easily remove it using Adobe Lightroom. This method is very impressive and the first time I used this feature in Lightroom I was happy with the fact that I can get rid of vignetting anytime I wish in the post-processing stage.

NOTE: You can use this technique of removing vignetting only if you are processing RAW files in Lightroom.

How to Add or Remove a Vignette in Adobe Lightroom

RAW file with a slight edge vignette captured in-camera.

How to Add or Remove a Vignette in Adobe Lightroom

Vignetting removed using “Enable Profile Corrections”.

As you can see in the screenshots above, the RAW format file had a hard vignette as this photo was shot using 50mm lens at f/1.8. In the second image, the vignetting has almost been removed with the help of one of the Adobe Lightroom’s handy features called “Enable Profile Corrections”.

This feature automatically detects the lens make, model, and profile, if it is available in the Adobe database. Lightroom has the lens profiles of almost every manufacturer, except for a few such as Samyang. This magical feature then corrects the vignette as well as distortion in your photo automatically. You can manually adjust them as well using the sliders. Isn’t that cool!?

To access this feature in Lightroom, you must be in the Develop module and the Enable Profile Corrections checkbox can be found under Lens Corrections tab on the right-hand side panel.

With just a click you can remove vignetting from your photo with Lightroom. Just make sure you are using the RAW format file only as this feature is not applicable for JPEGs.

How to add a Vignette with Lightroom

1) Using the Post-Crop Vignetting Feature

How to Add or Remove a Vignette in Adobe Lightroom

One of the easiest ways of adding a vignette to a photo is by using the Post-Crop Vignetting feature in Lightroom. You can find this tool located under the Effects drop-down menu. To keep it simple, you can start with moving the Amount slider towards the left (a negative number) in order to add the vignetting effect. Then you can adjust the Midpoint slider to define the spread of vignetting effect in the photo as per your desire.

The Roundness slider further allows you to define the shape of the vignette on the photo and the feather slider lets you define the falloff or how gradually it fades to the edges. The Highlights slider allows you to retain the highlights from the parts of the photo where you have applied the vignetting effect.

The only limitation of this approach is that you can not adjust the placement of the area where the vignetting effect starts. It only gets applied from the edges of the image moving towards the center (the vignette is centered).

2) Using the Radial Filter

How to Add or Remove a Vignette in Adobe Lightroom

The best thing about using the Radial Filter to add a vignette is that unlike the post-crop vignetting tool, you can change the position of the area where the effect gets applied. This means that you can select a particular area which remains unchanged as shown in the image above, and the vignette effect can be applied to the rest of the image.

As you can see in the image above, the Radial Filter tool gives you the freedom to play with much more diverse adjustments such as White Balance, Shadows, and Clarity. To start with you need to click and drag to select the area outside which you wish to apply the vignetting effect. Once that’s done you then can get started by adjusting the sliders.

Initially, you will have to bring down the exposure to darken the area selected, then you can play with the sliders to get the desired result.

Conclusion

    OWC launches ThunderBlade external SSD: up to 8TB with 2800MB/s speeds

    11 Apr

    $ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_0425244729″,”galleryId”:”0425244729″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

    Media professionals in need of a fast, reliable, and high-capacity external SSD have a new option in OWC’s ThunderBlade. This external drive, which has started shipping to customers, is offered in 1TB to 8TB capacities with up to 2,800MB/s read speeds and 2,450MB/s write speeds. According to OWC, these transfer speeds make ThunderBlade its fastest external drive yet.

    Inside each ThunderBlade you’ll find four M.2 SSDs—up to 2TB per SSD—each of which has its own dedicated piece of the front-facing LED. According to the drive’s user guide, “when one or more of the SSDs are accessed for read/write operations, the corresponding segments will blink blue.” Of course, that doesn’t mean you ‘max out’ at 8TB.

    Every drive features two Thunderbolt 3 ports, which allow you to daisy chain up to six ThunderBlades together and configure them in Software RAID 0, 1, 4, 5, and 1+0. And SoftRAID allows a pair of ThunderBlade drives to hit read speeds of up to 3,800MB/s. The ThunderBlade’s read and write speeds enable it to handle uncompressed, high-bandwidth media, making it an ideal choice for photographers, video editors and other professionals dealing with large amounts of data.

    In addition to blistering speeds, OWC designed ThunderBlade to be durable and includes a ballistic hard-shell protective case with the drive. ThunderBlade can operate in temperatures ranging from 10°C to 65°C (50°F to 95°F), measures 3cm x 12.3cm x 7.5cm (1.2in x 4.9in x 7.5in), weighs 0.7kg (1.8lbs), and supports both Windows 10 and macOS 10.13 or greater.

    The OWC ThunderBlade is available to purchase from several online retailers, at the following prices:

    • 1TB: $ 1,200 USD
    • 2TB: $ 1,800 USD
    • 4TB: $ 2,800 USD
    • 8TB: $ 5,000 USD

    And since you can daisy chain up to six devices together, your total storage tops out at 48TB for $ 30,000—a good chunk cheaper than the G-Technology G-DRIVE Pro SSD Western Digital announced yesterday.

    To learn more about the drive, head over to the OWC website or dive into the user guide here.

    CorePhotonics white paper explains the pros and cons of the triple-camera

    11 Apr

    A couple of weeks ago, we saw the first announcement of a mobile device with triple-camera in the shape of the Huawei P20 Pro. Gil Abraham, Director Product Management at Corephotonics—an Israeli company that specializes in the development of smartphone camera solutions—has taken the opportunity to author a white paper titled “Triple cameras: Are three better than two?”

    The document looks at the evolution of dual-camera systems from the HTC One M8 to current models, such as the iPhone X, and then jumps straight into the challenges and rewards of camera systems that feature a third camera.

    Abraham says the main challenges for the design and development of triple-camera solutions are cost, space and calibration, as well as firmware, algorithms and power. Three cameras inevitably need more space than two in the already very close quarters inside a thin smartphone and, depending on configuration, a third sensor and lens can add between $ 10 and $ 30 to the device’s bill of materials.

    Very careful calibration of the entire setup is also needed in order to avoid any artifacts during image fusion—firmware and algorithms have to be tuned to control three physical cameras that should work as one. Power consumption can also be greatly affected if not all hard and software components work together efficiently.

    In the final part of the white paper three triple-camera configurations are presented in detail, and their pros and cons explained. There is a zoom camera for low-light conditions and a fish-eye zoom that offers focal lengths from fish-eye to tele. It’s the third variant, however, that we really hope to see on a production device very soon.

    The “Super zoom with excellent low-light” offers a 5x optical and 25x overall zoom combined with good low light image quality using Corephotonics’ folded optics with OIS that we have already seen in an Oppo prototype device.

    Overall, Abraham’s white paper is an interesting and educational read for those of us wondering where smartphone camera technology is headed. To dive into the details, read the complete white paper on the Corephotonics website.

    SLR Magic announces new MicroPrime CINE lenses for Sony E-Mount

    11 Apr
    Credit: SLR Magic

    Lens maker SLR Magic is exhibiting a new lineup of cinema lenses at NAB 2018 this year. The new MicroPrime CINE lenses are designed for the Sony E-Mount, and there are five of them in all. The first four—a 25mm T1.5, 35mm T1.3, 50mm T1.2, and 75mm T1.5—will all be released in May, and a fifth 18mm T2.9 will be ready “by Q3 2018.”

    According to SLR Magic, the MicroPrime lenses are designed with an image circle large enough to cover full-frame sensors, a similar weight distribution across the lineup for easy lens swapping when using a gimbal, and an internal focusing mechanism. The company also says the focus gears were designed with “a throw slightly longer than photographic lenses but still manageable when a motorized follow focus is not used.”

    The image below shows a basic set of specs for all five of the MicroPrime CINE lenses, although there is one mistake in the table: the lineup features an 82mm filter thread across all five lenses, not 77mm as the image below shows.

    Hong Kong, China (April 9th, 2018) – SLR Magic will present a new family of CINE lenses, MicroPrime series, to the public in the upcoming NAB Show 2018 in Las Vegas at the SLR Magic booth (Upper Central Hall, C-2663). The SLR Magic MicroPrime CINE 25mm T1.5, 35mm T1.3, 50mm T1.2, and 75mm T1.5 are the first lenses of the family.

    The SLR Magic MicroPrime CINE lenses are designed to be compact and robust for use in a professional setting. The MicroPrime CINE lenses have a large image circle that covers up to full frame. Witness markings on the lenses are all calibrated for the accuracy professionals need in the field. Each lens is balanced, with a similar weight distribution so that recalibration is not required upon switching lenses when using a 3-axis gimbal. Lens gears are built-in with a throw slightly longer than photographic lenses but still manageable when a motorized follow focus is not used. Each lens features an internal focusing mechanism, and comes with a standard 85mm diameter suitable for matte box use. In the situation where a smaller setup is required, each lenses also comes with a 82mm filter thread for use with 82mm Fixed ND filters.

    We place the highest priority on the development of our lenses, to fulfill the demands of professional cinematographers.

    SLR Magic is exhibiting the first lenses of the MicroPrime cinema series at the 2018 NAB Show. The SLR Magic stand will be in upper central hall (C-2663) during the show, which is to be held in Las Vegas from the 9th to the 12th of April 2018.

    The SLR Magic MicroPrime CINE 25mm T1.5, 35mm T1.3, 50mm T1.2, and 75mm T1.5 (MSRP: $ 800 US) will be available from authorized SLR Magic dealers starting in May 2018. The SLR Magic 18mm T2.9 will be ready by Q3 2018.

    iFixit teardown reveals OIS on all three cameras in the Huawei P20 Pro

    The team at iFixit has performed its usual teardown on the new Huawei P20 Pro triple-cam equipped smartphone to assess the device’s repairability. The score for the latter is 4/10—which means it’s probably advisable to leave repairs to trained service personnel—but far more interesting to us photographers is the detailed look iFixit got at the Huawei triple-camera setup.

    You can see the full teardown here, but the main and most pleasant surprise is that Huawei actually built in more stabilization than their specs revealed.

    In the official Huawei specifications, only the tele-lens with 80mm equivalent focal length is listed as optically stabilized, while the RGB main camera and the the monochrome secondary unit rely on the Kirin chipset’s neural processing unit for ensuring sharp images. However, according to the iFixit engineers, all three cameras come equipped with OIS hardware, which makes us wonder if there are plans to activate this hardware via a firmware update at some point in the future.

    The image above shows the triple-camera in all its glory. The primary RGB camera is placed at the center of the setup and uses a large 40MP 1/1.7 inch sensor with an F1.8 aperture and a maximum ISO setting of 102,400, on the left you can see the 20 MP monochrome camera with F/1.6 aperture, and the 8MP/F2.4 telephoto is on the right. Next to the triple-camera the engineers have placed the 24MP front unit.

    NAB 2018: Watch these high-speed camera robots ‘dance’ at the Nikon booth

    11 Apr

    Nikon-owned Mark Roberts Motion Control (aka MRMC) brought its high-speed Bolt and Bolt Junior ‘cinebot’ camera robots to NAB this year. And in a fit of “just because we can, probably means we should,” the company decided to choreograph a little dance number for the two robots on the showroom floor.

    DPReview decided to skip NAB this year, but friend of the site Jim Goldstein graciously allowed us to share his two videos of the bots in action. To quote Jim, it seems it’s “Out with ‘booth babes’ at NAB and in with ‘booth bots’.” We 100% support this change.

    You can see the full routine from two angles in the video above and below.
