Schlieren Imaging has always been a very narrow and specialized field of imaging. It can visualize air perturbations in a fluid-like way that can show the reach in this case of someone’s breath and heat dissipation to see if a mask makes a large enough difference in transmission of infected airborne particles compared to no covering.
By using a Phantom VEO4k 990 slow motion camera at 938fps and a speckled background with specialized angled lighting, researchers were able to test a variety of masks while coughing to see the effects. You can watch the video posted here and also check out the full study available here if you want to dig deeper. → Continue Reading Full Post ←
Canon has now released the final specs and estimated release dates for the EOS R5 and R6 cameras. There is a lot of good advancement in features especially in video mode as what many believe is an afront to Sony and Panasonic who dominate video recording on ILCs. The R5 can record 24fps and 30fps 8k video or 8192 x 4320 pixels in RAW quality which is a staggering 1TB of storage or 2600 Mbits/s for only 51 minutes of recording time. That means that every hour you will eat up through a full TB of your RAID backup storage. We see this mode being transcoded to an intermediate format like Blackmagic RAW or BRAW or Apple ProRes as soon as possible.
There is more bad news, on the 120fps 4k front there is no other option of recording but All-I which saves every frame independently in 10-bit 4:2:2 which is good for excellent quality but at the cost of 1,880 Mbits/s which is 224MB/sec or 13,447MB / minute of recording time. Better get a ton of memory cards and hard drives ready! → Continue Reading Full Post ←
Panasonic has released a Beta tethering software package for use in Windows 10 that allows you to control your Lumix camera from the computer to shoot images and video while at the same time use it to monitor the live view video signal with now the specific change that lets you remove the overlay display items from the camera to get a clean feed to your video conferencing software.
However, it is not that easy to get it to work and requires a couple of free pieces of software to let you extract the live view feed from the camera and redirect it to a video conferencing application of your choice. We were able to get it to work well and it really makes a difference compared to the small sensor webcams you have been using. Place a 1.4 lens in the camera and look at the beautiful feed that will result by using a professional camera and optics system to make you look better. → Continue Reading Full Post ←
There has been an absence of real world samples of the OnePlus 8 in slow motion due to mainly of the hardware not reaching testers fast enough and the COVID 19 pandemic slowing things even further. However, we have found a video that shows the OnePlus 8 Pro being compared to the Samsung S20 Ultra and the iPhone 11 Pro in the 240fps slow motion mode.
It is clear that the OnePlus 8 has a more processed image with higher saturation and apparent detail retention. It is also notable that dynamic range seems to be a winner in the OnePlus as well. The quality offered by the new handsets from the Chinese company is really astounding considering more expensive phones simply cannot seem to fully compete here. While more samples are needed the footage below shows a good enough view of what you can expect. → Continue Reading Full Post ←
We were very skeptical earlier in the year when the R5 specs were just a rumor. Canon has not really been delivering powerful video features out of their Cinema line and we expected this new camera to be a crippled continuation of the trend. We were not only wrong but now know that Canon is banking the future of the EOS line on cameras like the R5 with features that really put it in a class all by itself.
The original video darling was the EOS 5D Mark II which made it possible to use the EOS line of lenses with a video mode that delivered good enough quality for the web and some careful productions. The camera had issues like severe rolling shutter and a tendency to moire and alias so bad that many shots were really ruined. However, the excellent Canon color quality and lens choices made it so popular that it really forced companies to change the video options forever. Now Canon intends to do as big a splash with the introduction of 8k video internally on the new camera. → Continue Reading Full Post ←
The Chinese company from Shenzhen OnePlus has always been regarded as a pusher and advancer of cutting edge technology at a price that is more affordable than most premium brands. The good news has always been that the lower price has not really made it a premium-less experience, actually, many of their phones are so advanced and feature-rich than many flagships from Samsung and Apple have trouble catching up in features like the 120Hz display refresh of the 7T last year.
Since the OnePlus 6 and 6T slow motion in 2018 made inroads by allowing 480fps 720p recording for an unheard of in the phone space “3.75 sec” recording time it has been one of the best slow motion phones to own. They repeated that feat with the OnePlus 7 and 7T in 2019. Now in 2020 after many pushed dates for announcement due to the pandemic situation they have now unveiled the OnePlus 8 and 8 Pro flagship phones. They are premium and advanced that compete head to head with the best out there. They also include 480fps and from the looks of the sample, it seems to be increased in quality with much less pixelation. → Continue Reading Full Post ←
