Exactly, Mark. 4K isn't worth it for me most of the time, much less shooting Log.On Thu, Jun 29, 2017 at 2:00 PM, Mark Spano cutandcover@gmail.com [Avid-L2] <Avid-L2@yahoogroups.com> wrote:
Isn't that a huge difference though? People should clarify their statements to something like: Log isn't worth the effort FOR ME. Without those two words at the end, it just sounds like generalized uninformed nonsense.On Thu, Jun 29, 2017 at 2:51 PM, bigfish@pacbell.net [Avid-L2] <Avid-L2@yahoogroups.com> wrote:I got clarification at NAB regarding Arri LogC and they have a mode that allows setting the proper exposure so that 18% Scene grey has a data value of 400. It allowed you to see where the 400 mark was in the picture.
I have to say that if you are delivering for Rec 709 and you shoot in Rec 709 you are getting the maximum number of step/levels out of the signal. Any compression and you lose steps in detail. If the final log signal I get was still a full 700 mV then I would say okay this process is still taking advantage of the full signal range and steps of detail and then I would feel it was protecting the under and over shoots but still maintaining detail. Whether the loss of detail, where ever it is, is more problematic than over or underexposed issues is certainly a judgement call.
I like to think the feature film world and other high end productions handle the log process I lot better than I usually see it but that is not the world I live in most of the time.

I'm inclined to say that because I understand how it works, I'm able to extract the benefit from it. There are lots of wacko theories being thrown around on this thread that make it sound like Log is worse. Those theories are wrong when Log is shot correctly. A scene lit and shot Log with a camera and codec of sufficient quality will best that same scene shot linearly for both high and low detail.If you don't think so, then don't use it. Leave it to those of us who can.On Thu, Jun 29, 2017 at 2:15 AM, Pat Horridge pat@... [Avid-L2] <Avid-L2@yahoogroups.com> wrote:I'd agree with Bourke. With an 8 bit recording SLog3 is trading mud tone sefinition for top and bottom and frankly its the mid tones that count. In 10 bit it works well IF you push tge exposure up while recording.
Much SLog content frankly doesn't use 1/3 of the available bit depth so is worse than useless.
SLog3 like many others is for many just a gimmick and a complication.
