Video: Watch 72 high-speed cameras capture bullet time slow-mo footage

13 Sep

Popular YouTube account Hydraulic Press Channel has introduced a major filming setup upgrade involving 72 high-speed Chronos 1.4 cameras mounted on a large rig suspended above the hydraulic press machine. The cameras are able to capture nearly 3,000,000 frames per second, according to the channel’s host, resulting in high-resolution 360-degree bullet-time videos.

The camera rig is used to show packs of playing cards exploding outwards under the pressure of the hydraulic press. It’s unclear how often this rig will be used for hydraulic press videos, but a comment published by the account indicates the team plans to introduce a new ‘Bullet Time Show’ on the Beyond The Press channel.

The Chronos 1.4 high-speed camera is offered by Kron Technologies with color and monochrome sensor options starting at $ 2,999.

Major Fuji X-T2 firmware update adds internal F-log recording, slow-mo, and more

09 May

Fujifilm has released a major firmware update for the Fuji X-T2 that may make it even harder for owners of that camera to justify the jump to the newly-released Fuji X-H1. As we mentioned in our review—and as Chris and Jordan pointed out in Episode 2 of DPRTV—the price of the X-H1 makes it a tough sell to owners of the X-T2 who have been looking to upgrade. And now, with Firmware Version 4.0, those users may not want to upgrade anymore anyhow.

Version 4.0 replaces version 3.0 (imagine that), and adds nine new features in all. Some of the video highlights include the ability to record 4:2:0 F-log directly to the SD card, and the addition of a 1080p 120fps slow motion mode. There are also major improvements to the Phase Detect AF algorithm, with the low-light limit dropping from +0.5EV to -1.0EV, the maximum aperture increasing from F8 to F11, and “major improvements” in AF-C performance while operating zoom. Finally, a focus bracketing feature has been added that lets you bracketing up to 999 frames in intervals of focus shift between 1 and 10.

There’s no word on whether the X-T2 gains the improved video processing of the X-H1 (it doesn’t gain 200Mbps capture), but this is one of the things we’ll be checking when we re-assess the X-T2 review in the coming weeks.

To learn more about this update or download it for yourself (and if you own an X-T2, you definitely need to download it ASAP), read the release notes below and then pay Fuji’s support website a visit.

Release Notes:

The firmware update Ver.4.00 from Ver.3.00 incorporates the following issues:

  1. Addition of “Focus Bracketing”
    The update will enable the photographer to shoot focus distance bracketing up to 999 frames. When the photographer starts shooting, the focal location is shifted with each activation of the shutter by the step of focus shift set from 1 to 10.
  2. Compatible with the newly developed cinema lens FUJINON MKX18-55mm T2.9 lens and FUJINON MKX50-135mm T2.9 lens
    • Aperture information can be displayed on the monitor. The upgrade allows users to select T-stop or F-stop.
    • The upgrade allows users to check the focus distance with the distance indicator shown on the monitor.
    • Automatically corrects the distortion and the color/brightness shading.
    • Camera automatically calculate the White Balance based on the lens position and deliver the color expressions with Film Simulation modes.
  3. Enlarged and customizable indicators or information
    The upgrade allows users to enlarge indicators and information in the viewfinder and/or LCD monitor. This upgrade will also enable users to customize the location of where the information is shown on the display.
  4. Addition of F-log SD card recording
    The upgrade allows users to record F-log movie data into their SD card.
  5. Addition of 1080/120P high-speed video mode
    The upgrade allows users to shoot 1080/120P high-speed video (1/2, 1/4 and 1/5 speed slow motion), ideal for recording spectacular slow-motion footage.
  6. Enhanced Phase Detection AF
    Latest updates to the AF algorithm provide the following performance enhancements:
    • The low-light limit for phase detection autofocus has been improved by approximately 1.5 stops from 0.5EV to -1.0EV, raising the precision and speed of autofocus in low-light environments.
    • The range at minimum aperture has been expanded from F8 to F11. For example, even when using the XF100-400mmF4.5-5.6 R LM OIS WR with the tele converter XF2X TC WR, phase detection autofocus can now be used.
    • Major improvements have been made to the AF-C performance while operating the zoom, which provides major benefits when shooting sports and other scenarios in which the subjects moves unpredictably.
    • Finely-detailed surface textures of wild birds and wild animals can now be captured at high speed and with high precision as a result of improvement in phase detection autofocus.
  7. Addition of “Flicker Reduction”
    For enhancing the quality of indoor sports photography, the upgrade allows users to reduce flicker in pictures and the display when shooting under fluorescent lighting and other similar light sources.
  8. Addition of “Select Folder” and “Create Folder”
    Enables the user to choose the folder in which subsequent pictures will be stored. And also enable to enter a five-character folder name to create a new folder in which to store subsequent pictures.
  9. New functions are added to store and read of camera settings by FUJIFILM X Acquire
    Once connecting a camera to a computer via USB cable, the “FUJIFILM X Acquire” allows users to backup/restore camera settings to/from a file. With “FUJIFILM X Acquire” (ver.1.7 or newer), CUSTOM REGISTRATION/EDIT settings are also stored and read.

Samsung teases Galaxy S9 low light and slow-mo performance

16 Feb

On the 25th of February, Samsung will unveil its latest flagship phone, the Galaxy S9, and the Korean company is already heavily teasing some of the new model’s new and improved camera features in a couple of short teaser videos on its Korean Youtube channel.

The first video (above) shows several low-light scenes in quick succession. Towards the end there is the silhouette of a deer in near darkness. The animal’s head brightens up when the number 9 appears around it, hinting at some kind of low-light mode or improved low-light capability in the camera.

Previous rumors have mentioned a variable F1.5/F2.4 aperture. The lower value would be one of the fastest apertures on any smartphone camera, but we’d suspect Samsung will add some clever multi-frame-stacking technology on top of that to achieve usable exposures in very low light and manage noise.

Another video is a quick succession of action-packed scenes. At the end, a skydiver is almost frozen in time as the number 9 appears, hinting at some kind of super-slow-motion capture. From what we know so far, the S9 will come with a 480fps 1080p Full-HD slow-motion mode.

These kinds of teasers always leave you with more questions than answers, but fortunately we’ll know more in 10 days time when the device is launched. We’ll be at the event in Barcelona, so stay tuned for more details!

Nikon D90 Slow-Mo Video Test – Prank Golf

27 Jan

This is a video intended to show the quality of the Nikon D90 video mode, not to show photographic creativity. You can see the “rolling shutter” a little without the slow-mo, but with it, you can see everything, and it is really irritating. But at least the prank was fun! 🙂
Video Rating: 3 / 5
