Gh5s Dynamic Range Test

Panasonic gh5 dynamic range test we can see that the sensor s total dynamic range is higher than those 10 usable stops but in a real world scenario i think the noisy shadows will have to be cut away in grading.

Gh5s dynamic range test. The heart of the difference between the gh5 and the gh5s is the sensor. Because you need the extra bit depth to provide room for that additional dynamic range. Dynamic range is above 8 f stops at all non extended isos measured. The gh5 was set to 4k 10bit 25p at 150mbps for the duration of the testing.

When used correctly this camera can still produce admirable results. The gh5 also showed a dynamic range of more than 9 f stops from iso400 to iso12800 and 10 0 at the lowest iso of 200. A dynamic range of 10 f stops equals a contrast of 1000 1. This is a process that has been used for quite some time in astrophotography.

Like the gh5 and 4 the gh5s can shoot using panasonic s v log l gamma curve to increase the dynamic range you capture and to make it more usable. Testing the neutral picture profile it s noted that the recorded image provides very little flexibility at 10 usable stops of dynamic range with whites and blacks pretty much remaining how they are recorded. I am recording dark frames at these isos. This additional pixel level dynamic range is the reason the gh5s needs to offer 14 bit raw files.

Every f stop equals a doubling of the contrast. Panasonic lumix gh5s iso test images. Since you can t shoot raw video on these cameras the next best thing is to ensure you make the best use of the limited bit depth of the 8 or 10 bit footage the camera can capture. Panasonic reverted to the old days of the gh1 and gh2 by using a multi aspect sensor with an optical low pass filter olpf.

This is how it works. Previous tests not published showed that the knee can capture about 2 5 times normal exposure 1 3 stops so the dynamic range for like709 can be extended to about 11 6 stops even with 8 bit recording. The best dynamic range is at iso800 where it is 10 0 f stops. Alan however notes that these dynamic range figures are a little speculative and subjective.

No list is perfect. Now this is actually a scientific test. Image engineering report the dynamic range normally in the common unit f stops or ev exposure value.
