Canon patent application sheds more light on its upcoming IBIS technology

17 Sep

Rumors about Canon’s much-anticipated in-body stabilization (IBIS) are a dime a dozen, but a recent patent application from Canon dives into more detail than we’ve seen before, further lending credence to the rumors the technology could make it into Canon’s next R-series camera body.

First discovered by Canon News, Japan patent application 2019-152785 details how in-body stabilization technology can be improved by more accurately moving and positioning the sensor along its axes. According to the patent, Canon plans to do this through the use of a magnetic circuit known as the Halbach array.

An illustration from the patent showing how in-lens stabilization would work alongside the in-body stabilization to achieve optimal results.

The Halbach array, believed to have first been discovered by John C. Mallinson in 1973, is a collection of magnets that is particularly arranged so that one side of the magnetic field is magnified while the opposite side is effectively canceled out. Halbach arrays have multiple uses ranging from something as simple as a refrigerator magnet to something as intricate as a particle accelerator (where it’s used to focus particle accelerator beams).

Canon’s implementation, however, would use Halbach arrays to ensure that when a correction is applied to one axis, it won’t negatively affect another axis. Particularly, Canon’s patent application details how it would use a Halbach array on the vertical (y-axis) stabilization unit to ensure that the horizontal correction (x-axis) isn’t skewed when applying y-axis corrections.

A pair of illustrations from the patent showing how the Halbach array would be positioned.

The patent application also explains how the IBIS would work hand-in-hand with in-lens stabilization units to create the most effective stabilization possible. Specifically, the patent says the in-lens stabilization would account for corrections on the XY planes (2-axis stabilization) while the in-body stabilization would be able to account for shake on XY-theta planes (3-axis stabilization with vertical, horizontal and roll compensation). Similarly, gyro units within both the lens and camera would work alongside one another to account for angular corrections so the image stabilization element in the lens could be adjusted in coordination with the image sensor to most accurately correct the optical axis.

Below is a brief illustration of XY-theta alignment at work:

It’s unknown, of course, if this particular patent application will be used down the road in a future IBIS arrangement, but it is one of the more detailed patents we’ve come across from Canon regarding the technology. Based on this particular patent application, it would be a 5-axis IBIS unit, similar to those found in Sony and Nikon mirrorless cameras.

How to Use Color in Your Photography to Give Your Photos the Wow Factor

17 Sep

The post How to Use Color in Your Photography to Give Your Photos the Wow Factor appeared first on Digital Photography School. It was authored by Jeremy Flint.

Photography is a wonderful art form that is enjoyed by people all around the world. It is a popular medium of expression, a fine art, a way of documenting our journeys and memories, and even a way to change views. Originally, when photography started it was all black and white, and historic photographers learned their craft in this way. Whilst this can be a great way to bring out textures and shapes, the introduction of color is a great way to attract attention and add impact to your images. Here are 5 tips to show you how to use color in your photography to give your photos the wow factor:

1. Find a colorful scene

The first thing to do is to find a colorful scene. The way the countryside unfolds in the summer, for example, can be a wonderful way to show color in a landscape. Purple hues of lavender or golden wheat fields are all examples of where color can be captured to help your images stand out.

You could focus on one dominant color in a scene such as green. Alternatively, seek out a variety of tones like a cool blue sky mixed with a red field which can give your photos some impact and evoke different emotions. Blue can provide feelings of cold, whilst red can give warmth, energy, and excitement.

You can also use complementary colors in captivating ways. They refer to colors on opposite sides of the color wheel. For example, red and green or blue and orange. Other colors that work particularly well together include yellow, red and orange; and pink, purple and blue.

2. Look for details with color

Another way to use color in your photography is to look for details with color. You can photograph individual flowers in bloom such as bluebells or plant crops. As a part of a broader scene, you can photograph flowers like vibrant red poppies swaying in a field.

Think about the different colors and details you could photograph near you and experiment with a variety of color palettes to see what works well. Try and find details to photograph with single colors and combinations of colors to see which you prefer. Red is a strong color that attracts the viewer’s eye whilst yellow and orange can also command attention.

3. Change your white balance setting

One great advantage of the white balance setting is that your camera has the ability to change the color of your images simply by adjusting the white balance.

There are several different types of white balance which can be varied according to different lighting scenarios – auto white balance is the default setting for most cameras. Shade, cloudy and daylight can be selected for warmer and brighter colors, whilst tungsten and auto present cooler colors.

As the name suggests, a ‘shade’ white balance setting can work well in lighting conditions with shade and shadows, whilst ‘cloudy’ is a good choice when it is overcast. There is also an option to manually adjust your white balance to alter the color temperature to your taste.

4. Use a polariser to boost color and contrast

One of the greatest accessories you can have in your photography kit is a polarizing filter. A polarizer is usually placed at the front of your camera lens and is a versatile piece of equipment that can be brilliant to help darken skies, minimize reflections and manage glare from water sources such as lakes or the sea.

Polarizing filters are also a fantastic way to improve your images by instantly enhancing the color and contrast in your images. They don’t take up much space in your kit bag and are useful for making your images more distinct. Polarizing filters particularly work well in landscape photography by bringing out colors and reducing haze.

5. Boost colors in post-production

You can also add color to images in post-production. One way to boost the color of your photographs is to increase the saturation in post-production. You will find a saturation slider in most editing tools. Both photoshop and lightroom offer an adjustment slider where the color can be increased by moving it to the right. There is also the option to increase the saturation of individual colors to make certain parts of your images more vibrant.

Conclusion

Using color can be a great way to enhance your images. You can find colorful scenes, vibrant details, adjust your white balance, add a polariser or adjust the saturation in post-processing to give your photos more impact.

Try these techniques and share your images with us below. Also, if you have any other tips, feel free to share those too!

Canon to Produce an 80-Megapixel Mirrorless Camera

17 Sep

The post Canon to Produce an 80-Megapixel Mirrorless Camera appeared first on Digital Photography School. It was authored by Jaymes Dempsey.

 

canon-80mp-cameraIf you’ve been hoping Canon will produce a high-resolution professional mirrorless camera, then you’re in luck.

Rumors that Canon has been working on a 70 or 80-megapixel mirrorless camera have been swirling for months, but several new pieces of information make it more likely than ever.

First, Canon has filed a patent for an 83-megapixel sensor, which may be at the heart of a new mirrorless camera body.

Second, someone claiming to have a prototype of the new camera has just revealed specs, including:

  • An 80-megapixel full-frame sensor
  • A larger viewfinder than the Canon EOS R
  • Dual SD card slots
  • A new joystick
  • A larger size than the Canon EOS R

If these details are accurate, then the new camera (dubbed the Canon EOS RS by Canon Rumors) will likely be a mirrorless replacement to the Canon 5DS/5DS R duo. The two DSLR cameras debuted in February of 2015, and Canon has failed to update them in the years since. Most notable about the two cameras are their sensors: 50.6 megapixels – the largest full-frame sensors in existence at the time.

The dual card slots will be a particularly welcome addition to the Canon EOS RS. Many professional photographers passed over the EOS R based on its single card slot, and it seems Canon got the message. So for photographers who require redundancy in their work, the Canon EOS RS will be a good choice.

And if the Canon EOS RS is truly 80+ megapixels, commercial photographers will appreciate the opportunity to push resolution to its limits.

Such a high-resolution sensor has its drawbacks, however. The larger the files, the faster you’ll fill up space. Plus, a sensor with 80 megapixels will have high pixel density, leading to small pixels. This can be a problem with regard to noise production: the smaller pixels are more likely to produce noise at high ISOs.

Let’s just hope that Canon puts out a high-quality sensor to complement the megapixel count! If you’re a Canon fan looking to make the change to mirrorless, then keep an eye out for news on the Canon EOS RS, which will likely be announced at the start of 2020.

Would you purchase the Canon EOS RS for its 80+ megapixels? Share your thoughts with us in the comments.

Video: Taking photos across California to recreate Apple’s macOS wallpapers

17 Sep

YouTuber Andrew Levitt teamed up with friends Jacob Phillips and Taylor Gray to recreate the stock wallpapers Apple includes with its Mac computers by traveling around and snapping them one photo at a time. The project required a trip into the blistering hot Death Valley National Park, as well as Sierra National Forest, Yosemite National Park, Mavericks and more.

The group of guys showed their endeavors in a newly published video detailing the project. Levitt notes that their final images aren’t quite the same as Apple’s due to different seasons, among other things, but that they’re representative of the experience and getting to see each destination in person. The five resulting images have been made available to download as wallpapers here.

Apple’s ‘MultiCam’ recording will be available on iPhone XS, XR and the latest iPads

17 Sep

During its iPhone 11 event last week, Apple showcased an as-yet-unreleased version of the Filmic Pro app running on the new iPhone 11 Pro. The app was capable of recording footage from multiple cameras simultaneously, for example, front and rear camera or wide-angle and primary shooter. According to Filmic Pro, the updated version of its app will be available in the App Store sometime later this year.

The multi-cam recording function uses a new API that comes with iOS 13 and, according to Apple, required a redesign of the camera pipeline on their devices. The good news is that the changes have already been made on the iPhones XS and XR, as well as the latest iPad Pro models, as explained in this WWDC session keynote.

A screenshot from the WWDC session that shows the supported MultiCam Formats on the iPhone XS.

However, having multiple cameras active and recording at the same time puts a lot of stress on the hardware, which is why multi-camera recording on the 2018 devices has some limitations. Only certain combinations of cameras can be activated simultaneously (see table below) and, depending on the hardware requirements of their app, developers might have to revert to lower-quality video streams to make the feature work.

A screenshot from the WWDC session showing what combination of camera modules can be used with the MultiCam API in iOS 13 on an iPhone XS.

It has not been clarified yet which camera combinations will be usable on the iPhone 11 generation but during the Filmic demo, the footage appeared to be recorded from all four of the iPhone 11 Pro’s cameras simultaneously.

Nevertheless, this is good news for owners of 2018 Apple flagship devices who will be able to use the new feature at least partly. The multi-cam API should launch with iOS 13 on September 19. We’d expect a bunch of third-party apps implementing the functionality soon after.

PocketWizard ‘E Release’ $10 firmware upgrade boosts range, features and reliability

16 Sep

PocketWizard customers who own the company’s Plus III and/or Plus IV wireless triggers now have the option of upgrading to its new ‘E Release’ firmware. The software update brings a number of notable improvements, including increased range, improved reliability when sending and receiving signals, a Quad Zone Channels increase from 16 to 32, and 80 new Channels for use with Long Range Mode.

The range for both supported PocketWizard models running E Release firmware is doubled for triggering remote cameras and flashes; it is increased to up to 5 miles when used with radios in Long Range Mode.

Though the firmware is only available for the Plus III and Plus IV (FCC frequency) models at this time, PocketWizard says it plans to release the software update for its MultiMAX II, FlexTT5 for Nikon, FlexTT6 for Canon, and PowerMC2 models in the future. The E Release is available for units purchased in North America and South America; it cannot be used with CE frequency units.

Below is a video shared by PocketWizard showing how photographer Michael Heeney was able to capture a rock climber from four diffrent perspectives thanks in part to the upgraded firmware:

PocketWizard warns on its website that the firmware can only work with other radios that have also been upgraded with the E Release firmware. Upgraded PocketWizards can be downgraded back to the company’s legacy firmware for use with radios that aren’t running the new software.

Customers who want to upgrade will need to purchase a $ 9.99 USD E Release firmware license for each radio. PocketWizard customers who purchased one of the supported models from an authorized dealer in the US or Canada after September 1, 2019, can download the E Release firmware for free.
