REC-709 – A true REC-709 camera should only have 5 stops of dynamic range!
In theory if two cameras are both set to REC-709 then the dynamic range should be identical as both cameras responses will be limited to the REC-709 specifications. The original REC-709 specification only allows for 5 stops of dynamic range … Continue reading
Canon C-Log on the C300 compared to S-Log.
First let me say that as yet I have not used C-Log in anger, only seen it at a couple of hands on demo events and in downloaded clips. From what I’ve seen C-Log and S-Log are two quite different … Continue reading
More Codec and Gamma Tests.
More Gemini, Samurai, AC-Log and S-Log sample frame grabs. See download box at bottom of post. I had thought, when I first wrote this post that I had discovered a strange issue where the 444 RGB recordings from the Gemini … Continue reading
S-Log on a non S-Log PMW-F3 and Log on an EX1/EX3
Note: There is something up with the frame grabs. For some reason they are very dark. I’ll look into this in the morning and get some more accurate grabs online. First of all let me say thanks to Ben Allan … Continue reading
EX1 and EX3 Picture Profiles.

I’ve been working some more on picture profiles for the PMW-F3, mainly matrix settings. You can download the full set by clicking here: ac-profiles. Download the zip file, unzip and place the “Sony” folder in the root of an SxS card … Continue reading
PMW-F3 Picture Profiles. First Batch.
OK here we go. Here are some notes from testing my PMW-F3. First thing is… aliasing… a zone plate looks pretty bad with a fair amount of aliasing. I had heard rumours of this from others with pre-production units, but … Continue reading
When should I use a Cinegamma or Hypergamma?
Cinegammas are designed to be graded. The shape of the curve with steadily increasing compression from around 65-70% upwards tends to lead to a flat looking image, but maximises the cameras latitude (although similar can be achieved with a standard … Continue reading
Understanding Gamma, Cinegamma, Hypergamma and S-Log
The graph to the left shows and idealised, normal gamma curve for a video production chain. The main thing to observe is that the curve is in fact pretty close to a straight line (actual gamma curves are very gentle, … Continue reading
