It is a well know fact that digital cameras can do things film cameras cannot, displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound and deleting images to free storage space. They are incorporated into many devices ranging from pdas and mobile phones called camera phones to vehicles. They have high power requirements and over time have become increasingly smaller in size, which has resulted in an ongoing need to develop a battery small enough... click here to read the rest of the story
Microsoft has released a new camera app that puts its focus on taking better pictures of people. The Pix app is now available for iPhone and iPad, and Microsoft says an Android version is in the works. When active the app is constantly recording and saves 10 frames before and after its shutter button is pressed. A series of algorithms then analyzes the recorded images, evaluating technical quality characteristics, such as sharpness or exposure, but also looking at facial expressions of human subjects.
Based on those characteristics among others, the app then selects three best shots and presents them to the user. The filtered shots are discarded to save space, but not before the image information contained in them is used to enhance the selected shots. For example, the app can brighten app images that have been captured in very dark conditions.
Additionally, Pix converts a bunch of similar images into a moving Live Image, but only if it thinks the motion in the scene is interesting. The app also integrates Microsoft's Hyperlapse feature. In addition to recording stabilized time-lapses, in its latest incarnation it also allows you to turn existing images into time-lapses or simply stabilize previously recorded video footage.
One of the most interesting aspects of Pix is that we can expect the app to get better with time. Anonymized settings data and information on what pictures users delete or favorite is sent back to Microsoft where developers look at the data and fine-tune the app's algorithms accordingly. Microsoft Pix for iOS can now be downloaded from the Apple App Store.
Chinese electronics manufacturer Xiaomi has today announced the latest model in its affordable Redmi line of smartphones. Looking at the device's body materials and specifications it would not look out of place in the company's flagship Mi series, though.
In the imaging department the Redmi Pro features a dual-camera setup that combines a 13MP Sony IMX258 1/3.06" sensor with a 5MP Samsung depth sensor. The dual-cam does not offer any optical zoom capability, like on the LG G5, nor does it combine the captured image information from both sensors for improved image quality, like on the Huawei P9. Instead, it uses the dual-camera to simulate the bokeh of a fast lens on a large-sensor camera, something we first saw on the HTC One M8. Like on the HTC and several other dual-cam devices, you can change the focus point of the image post-capture in the gallery app.
There is also a dual-tone LED flash and at the front the Xiaomi comes with a 5MP selfie-camera. Images can be viewed and composed on a 5.5" 1080p OLED display with full NTSC gamut. A fingerprint reader is on board for increased security and all the electronics are provided with power by a beefy 4050mAh battery that supports quick charging via a USB Type-C port.
The components are wrapped up in a gold or silver brushed metal unibody that gives the device a premium look. The Redmi Pro comes comes in several versions that differ in terms of processor power and memory. Pricing starts at approximately $225 for the deca-core Helio X20 chipset, 32GB of storage and 3GB RAM and go up to approximately $300 for the faster Helio X25 chipset with 128GB storage and 4GB of RAM.
Photography community and marketplace EyeEm is making it easier for photographers to join its service by opening up its Web-based image uploading tool to all new and existing users. The uploader tool first launched last year for Market users looking to sell their photos through EyeEm. Using the tool, photographers can transfer images from services like Flickr and Google Drive to EyeEm, the latter of which auto-suggests tags based on an analysis of each image.
EyeEm supports uploading images from a local computer and the Web services Flickr, Dropbox, Google Drive, and Picasa. After a photo is uploaded, users can add the photo location, manually add tags, and choose from auto-suggested tags. Users can also opt in to EyeEm Market, where they may sell photos and receive 50% of the sale price.
It's no coincidence that EyeEm's announcement comes on the heels of the news that Yahoo-owned Flickr will soon be owned by Verizon. A post on EyeEm's blog appeals to those who are 'concerned about the unclear future of Flickr', and stresses that easy importing and auto-tagging should ease the pain of making the transition from another photo sharing community.
The EOS-1D X Mark II is Canon’s newest flagship DSLR aimed at pro-level photographers. A quick glance reveals the camera’s 1D-series heritage, but under the hood there are some exciting upgrades going on. The 1D X II is built around a new 20.2MP full-frame CMOS sensor, now with Canon’s Dual-Pixel autofocus system, includes an expanded 61-point autofocus system with 24% more coverage and a 360,000-pixel RGB+IR metering sensor, and is one of the first Canon DSLRs (other than the somewhat niche 1D C) that captures 4K video. Predictably, it’s also built like a brick and performs like a Formula 1 race car.
Canon 1D X Mark II Key Specifications
New 20.2MP CMOS full-frame sensor with Dual-Pixel autofocus
14fps continuous shooting (16fps in live view)
200+ shot buffer with Raw+JPEG (CFast 2.0)

The 1D X Mark II is a camera that anyone with previous 1D series experience can probably pick up, dial in their favorite settings, and start shooting right away — though as we'll see on the following pages, in doing so one might overlook advancements that Canon has made in this newest edition. There are a few minor tweaks to the body - all for the better in our opinion - and it takes very little effort to adapt. This conservative approach to design is a testament to the fact that the basic form factor works well. It’s no surprise that the designs of both the Canon 1D and Nixon Dx series are quite similar and haven’t seen many changes to the basic design over the years.
Conservative changes to the body notwithstanding, the 1D X II is full of new and updated technology designed to make the camera one of the top performing models in the world. The new AF system, although still utilizing 61 AF points, now covers 24% more of the frame and is, predictably, extremely fast. There’s also a new 360,000-pixel RGB+IR sensor for face recognition and subject tracking, which Canon refers to as iTR (Intelligent Tracking and Recognition).
The jump to 20MP (vs. the 1D X’s 18MP) isn’t exactly Earth shattering, but this is a completely different sensor than any found in Canon's previous flagship models. The 1D X II is the first full frame EOS DSLR to include Canon's dual-pixel autofocus system, a feature we've praised on other cameras. Additionally, Canon has moved to a design that uses on-chip analog to-digital-conversion, which should result in improved dynamic range of the sensor.
Compared to the Nikon D5
The obvious point of comparison to the 1D X II is the Nikon D5. A quick comparison reveals a lot of similarities and a few differences. On the surface it appears that Nikon takes the prize for high ISO and AF specs, while the 1D X II wins on continuous shooting speed and video. On the following pages we'll try to give you a sense of how they stack up in the real world.

We doubt that many people are going to seriously contemplate a switch between Canon and Nikon over a few specs on one model or the other unless it's something absolutely mission critical. Most shooters utilizing this type of camera are likely heavily invested into a system, including lenses, strobes, and even institutional support. At the same time, it's instructive to see just how advanced both flagship models are getting. We expect that most pros or advanced amateurs could produce great results with either one.
Canons new EOS 50D bridges the gap between the novice and the seasoned pro with a perfect combination of high-speed and quality.
