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.
SIGMA has released a compelling video showing their new process for ceramic lens filters being compared to other brands in a metallic ball drop test. The ball weighs 49 grams or 1.7 oz and it is dropped from a height of four feet.
According to SIGMA, their strengthening ceramic process is 10x or 1000% stronger than previous strengthening methods which are included in the video as the competition to compare them.
For many of us it seems counter intuitive to own a camera that doesn’t shoot color images. In this day and age of technological marvels, being constrained by black and white / monochrome output on recording is a strange proposition. For the world of high speed imaging however you have to re-examine the entire debate from a benefits point of view and why it could be ideal to have monochrome instead of RGB color as your high speed option.
Depending on the intended use Monochrome might give you more bang for your buck and save you a lot of money on lighting and power requirements to run those lights. To understand the benefits we need to dig in on why Monochrome camera sensors excel in areas where color sensors suffer and why this will hardly change with current sensor technology in the near future.
