1D X and D4: At the Limits of Exposure

In this second synthetic test of our 1D X and D4 evaluation, we are going to look at dynamic range, or more simply put, we’ll test how much usable detail we can push up from the darkest areas and pull back from the brightest areas in the RAW files of these cameras. Previous articles in the series:

If you are a photographer, you can probably guess which half of the image below offers a greater chance of recovering a usable image:

Left half: 5 stops underexposed, right half: 3 stops overexposed

Left half 5 stops underexposed, right half 3 stops overexposed

We had a pretty good idea, too, but decided to test it anyway and in the process, compared how good the cameras in our test are at recovering information from under- and overexposed areas of the RAW image. Continue reading

1D X and D4: Testing the ISOs

As the first part of our testing we put together an ISO noise test against several other cameras. If you’d like to read our series of posts on the 1D X and the D4 from the beginning, the introductory post was:

So, in addition to putting the cameras through their paces in real-life shooting, we also wanted to do some more controlled testing, so we set up a test scene at the studio. There are more details on the test setup at the end of the post, but for now, let’s take a look at the test scene:
