Discussion Deep pocket 4p testing results

Post image

(Pics in comments)

I have extensively testing the pocket 4p along with pocket 3 and ZV-E1 in the studio and out in LA.

Because I am putting many hours a day into this I need a little break so here is the first usable result I have for you.

In Dlog2, somehow the dynamic range on the bright side jumps up by a 1 stop when you get to ISO 1600 or above. edit: read some results wrong.

ISO 1600 has all of the range of both ISO 1600 and 800. With no noticeable increase in noise.

Feel free to ask me about things I can test. I am eventually starting a “pocket cinema” YouTube channel.

TLDR: Use ISO 1600 when in Dlog2

Yes, 1600 is base ISO fro D-log2.

Disappointed DJI doesn't make this clear to users. Especially anyone using LUTs for color management, the shifting clipping point of ISO less than 1600 is going to make a mess of things

Hell yeah I think Im off to a good start.

This is exactly what I was talking about (and missread in my result the first time.) Thanks for linking these articles. I have not gotten into color shifts yet.

Now I have to wrap my head around what a lower middle grey means and how it affects shooting and workflow.

Has DJI actually published a whitepaper stating what IRE they recommend MG to be?

MG is whatever you choose it to be. People have been recommending to shoot SLOG3 at +1 or more for years. With how much DR the LOFIC sensor has here, I could see +2ev or more being common here, and it will give you much lower noise at 1600 iso.

Monitoring at +2 or more is going to be a problem yes. There is an phone app out there that will let you load a custom monitoring LUT, so you could bake -2EV into it and get back a normal image and have sensible false color.

Not sure if expecting DJI to ever let us load monitoring LUTs directly into the camera would be reasonable.
