Solar Eclipse Slow Motion Recording?

We have received quite a few messages about how to shoot the solar eclipse next Monday, August 21st 2017 in slow motion.  After all the more frames you capture, the more temporal detail that will be preserved but there is a threshold when diminishing returns from shooting high fps take a toll on image quality, dynamic range and color accuracy.

In short, the rule of shooting the total solar eclipse at high speed will be based on timing on one hand and detail retention on the other. We have found in our research that you really do not need more than 120fps in order to get a great solar corona snapshot with enough detail and variance.  24 and 30fps regular frame rates are also good and perfectly acceptable.[...] → Continue Reading Full Post ←

Sony a6500 New Slow Motion Samples!

Sony a6500 New Slow Motion Samples

We have now a fairly good amount of slow motion samples for the Sony a6500 compact APS-C Camera to share with you.  It is clear that the quality this camera can provide is above the norm but we still do see some aliasing in diagonal fine lines which is to be expected by a sensor that is skipping some of the lines to achieve 1080p 120fps.

While the 4k UHD in this camera is derived from an oversampling of 6k; the 1080p 120fps is being extracted from a 24.2MP sensor using a 13MP effective crop factor 1.9x;  is throwing away some line information to get there. Also the camera caps frame rate output over HDMI at 60fps so there is no way to record super slow motion to an external recorder at 120fps.[...] → Continue Reading Full Post ←

Sony a6500 Slow Motion and Overheating!

Sony a6500 Slow Motion

The Sony a6500 came as a big surprise to a6300 owners in that their camera was loosing value overnight in the secondary market to a near identical close with a touch screen and IBIS stabilization.  However the camera has still not reached the hands of many pre order customers but we were able to find a few insights on the 120fps full HD slow motion mode.

The quality should be very similar to the a6300 since the sensor is identical but with slight improvements in the dynamic range and color pipeline should yield a slight increase in per pixel definition. The compression should be very close with the XAVC-S codec at 21Mbps at 24p and or 50Mbps at 60p with easily selectable formats.[...] → Continue Reading Full Post ←

Metabones Updates Adapter Firmware!

Metabones speedbooster m43 Ultra

Metabones the company that brought you the speed booster and one of the first to offer electronic lens compatibility including AF for Canon lenses on mounts like Sony E Mount and Panasonic/Olympus micro 4/3rds has updated the firmware on these to have better overall compatibility with AF modes on newer cameras.

Slow motion shooters on Sony, Panasonic and other slow motion capable cameras are big fans of these adapters and speed boosters because it allows compatibility with their Canon EF glass collection. Furthermore the speed boosters enable wider field of view and an extra stop of light which is always needed when shooting high speed footage.[...] → Continue Reading Full Post ←

Drone Experiment Hitting Flesh In Slow Motion!

PigSkinDroneAalborgUniversity

Aalborg University’s Drone Research Lab based in Denmark  has tested a catapult contraption with a Drone rotor and propeller against pig flesh. The results seem to be as you would expect even before you attempt the experiment. A given hypothesis is that a high speed propeller can cause some damage to skin or flesh as any sharp object would.

It is interesting as an experiment but there seems to be  a lot of negative press about this from several news and tabloid sources. Drones get a bad rap and continue to be a favorite of regulation advocates for privacy and security. There will be more experiments made with larger and diverse drones as time progresses.[...] → Continue Reading Full Post ←

Samsung Pulls the NX1 and GH4 Gets Post Focus!

isgnx1

Samsung has pulled out the German market with the Samsung NX1 camera for lack of adoption it seems or a big marketing failure. Will other markets be impacted in the future?  It is quite a capable camera with 4k video and 120fps Full HD recording which currently sits in #11 in our Camera Guide for slow motion on a budget.  While the line may continue in the future those prospects have become more doubtful in recent days with the announcement.  The good news is that the camera may be heavily discounted by years end getting you a great bang for your buck with pretty respectable slow motion capabilities for a mirror-less camera.

EOSHD has the detailed rundown on this NX1 story here![...] → Continue Reading Full Post ←
