Sony IMX183 ExmorR Could Be In New RX Series!

Sony IMX183 ExmorR

Sony Semiconductor division has announced the new  IMX183CLK-J “Mono” &  IMX183CQJ-J “Color” Sensors in 1″ size. The sensor seems to be a step up compared to the ones used in the last RX100 and RX10 camera series.  While there is no mention in the press release of a stacked combo; the sensor itself should be able to be built on a high speed stacked memory package which should allow extreme frame rates at HD resolutions.

The sensor used in the RX100 V, for example, is a 1″ Exmor RS which allows for HDR capture in both photo and video modes. The new sensors announced are of the R variety “No video HDR” which could mean another variation of the sensor will debut with the RX100 VI.   Considering the cameras are due for a refresh this year we expect Sony to up the ante when it comes to read-out data speeds and use their stacking technology.

Schlieren Imaging Slow Motion DIY!

Schlieren Imaging Slow Motion

Sometimes all it takes to embark on a new project is some unexpected inspiration.  On the Incredible Slow Motion video by Veritasium – Seeing the Invisible: Schlieren Imaging in SLOW MOTION we are not only inspired but awestruck by the results of this simple and doable at home scientific experiment.   The experiment allows a camera to visualize the vortexes of gases and temperature differences in the air which serve to create some very interesting scientific experiments and or artistic visualizations.

You will need a Concave Parabolic Mirror like the ones used in reflective Newtonian telescopes, “you may have one lying around from your stargazing days”,  you will also need a small light source like an LED flashlight or single diode and finally a razor blade or similar precise object to cut off the light to the camera on a plane.

Fake Slow Motion Is It Worth It?

Fake Slow Motion

There has been a lot of work put it developing software that can interpolate frames for video editing and compositing applications. Twixtor in the late 90’s was perhaps the first time the technology could make something worthwhile and really produce acceptable results in a computationally acceptable timeframe.

Today the most used algorithm is Adobe’s Optical Flow in Premiere or Time Warp in After Effects which use vector directional plus acceleration of pixel values to derive in between frame data to generate new frame information from the preceding frame as point A and the next frame as point B.  The results can do some wonders to really slow down things above the frame rate ceiling of the camera.

Olympus Tough TG-5 Digital Camera 120fps 1080p!

Olympus Tough TG-5

Olympus is announcing the TG-5 rugged camera which is the replacement for the popular TG-4. It has quite a number of new features and what may be a first for this type of cameras; a sensor pixel density reduction from 16MP to 12MP. A welcomed addition that will ensure better low light quality with a BSI CMOS sensor and speedier data acquisition which lets it output 4k and 120fps 1080p video.

It has also a 720p 240fps mode and a VGA 480fps mode which makes it stand out in the slow motion categories. This camera seems to be aiming at the GoPro Hero 5, Yi 4k+ and Sony Action Camera markets with more features, better usability and the features you expect from a portable camera. It can also be used in drones with some creative placement due to its low weight of 250g with battery!

Yi 4k+ Slow Motion Samples!

Yi 4k+ Slow Motion Samples

The Yi Technology Yi 4k+ has been shipping for a few days and now slow motion samples have been posted online. There is no question the Yi 4k+ is the best value in action cameras today with specs that reach 4k at 60fps and up to 240fps in 720p Wide mode.

There is, of course, a resolution decrease and softness increase when it reduces the frame size to extract frames but it is within the norm and very competitive image quality wise with GoPro Hero 5 and Sony Action cam.  There are nearly identical components inside the Yi 4k+ to other action cameras and the Ambarella H2 Chipset makes its debut on the Yi line with good performance.

Sony Xperia XZ Premium Slow Motion Shooting!

Sony Xperia XZ Premium Slow Motion

We already stated that the Slow Motion performance of the Sony Xperia XZs & XZ premium should be identical given that they share the exact same camera module based on a stacked memory sensor design. However many readers have asked if there is a difference between both phones.  Considering the latest samples released we can state that when it comes to slow motion shooting the XZs & XZ premium are identical.

The camera has a slow motion mode that takes very short bursts about 0.2 sec each to generate slow motion video in a 720p H.264 video stream. It is limited and you need trial and error to succeed but in the end, you can get terrific looking high-speed video that simply is unmatched by any other smartphone to date.
