Tony Northrup put the Nikon D5 and Sony A7R II side-by-side for an ISO comparison when shooting video. He ran the comparison up to ISO 3,276,800, which is seven stops beyond the A7R II’s capability. He pushed the exposure for the A7R II in post to match the D5 and it held up quite well.
This article on Giving Your Video That Cinematic Look – Why Understanding ISO Is Just as Important as Having the Right Gear is from guest author Corey Benoit.
From Still to Motion
Like many, my projects require both still and motion images and are often lacking essential light to simplify the production. Switching between the two, I have found that understanding ISO is equally as important as selecting the right gear for your shoot. This article takes a look at ISO and gear for creating cinematic video in low light situations.
The ISO Myth
Many photographers and videographers think that ISO only affects the overall exposure of the image or the light being received by the sensor, and this is a myth. ISO doesn’t just affect the exposure or the lightness/brightness of an image. It basically destroys the color integrity and accuracy. Your greens will take on a lighter shade and will most likely have noise. Reds turn into more of an orangey kind of red, and blues will typically take on a cyan color. Color pollution is a problem with higher ISO. The color matrix will be polluted the more you push the ISO. Not to mention the damage that is done to the black/gray shades. They are polluted very badly with higher ISO. [Read more…]
How amazing is the Sony A7s’ low light capability? Watch this video.

Previously, I shared the Sony A7s press conference unveiling and a rudimentary ISO test of the Sony A7s with several sample images at 100% shot on the show floor for NAB 2014.
Aside from the 4K capability, one thing everyone is talking about on the new Sony A7S is the new 12MP sensor and the ridiculous low light sensitivity that it delivers.
I got some hands-on time with the Sony A7s today and took several shots at various ISO levels. Below, I have assembled 100% crops of the images from the center of the frame from ISO 100-102400. [Read more…]

What is a “Stop” of Light?
The concept of a “stop” of light is probably the most important concepts in photography, yet it’s widely misunderstood. In this article, we want to take you back to the basics to help visualize a stop of light and changes in exposure.
A stop of light is not a quantifiable unit of light entering the camera but rather a relative one. Therefore, increasing by one stop doubles the amount of light let into the camera while decreasing by one stop cuts the amount of light in half. [Read more…]
I just got my hands on the Fuji X100, and after reading all the praises this APS-C format camera has received for its image quality, I wanted to take a closer look.
Nikon D3s – ISO 3200 – f/2.8 – 1/1000s
One of the three components of exposure of photographs is the sensitivity of your image sensor or film inside your camera. This measure of sensitivity is expressed as ISO speed – and it’s kind of a big deal when your light is less than ideal. [Read more…]
Yesterday, I showed off a little of what Lightroom 3’s noise killing prowess could do. And then, I started looking back at some of my basketball photos from this season, most of which were shot at ISO 3200. Some of them could use a little help from Lightroom 3’s noise reduction panel; however, some looked just fine, even with a little bit of grain. [Read more…]
