studiodc Posted August 14, 2015 Share Posted August 14, 2015 Interesting, but can we see a GH4 -> "Log" -> CLog LUT applied comparison, too, at full res?I'm especially interested in what that transform gives us for skin tones and foliage.

Much less yellow cast to warm hues. kaylee 1 Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted August 14, 2015 Author Administrators Share Posted August 14, 2015 Here's a quick example - fixing yellow cast of original shot by converting GH4 footage to LOG in Premiere (based on Canon LOG) and applying my 1D C LUT.Forgive my rather crowded LUT folder Cinegain 1 Quote Link to comment Share on other sites More sharing options...
AaronChicago Posted August 14, 2015 Share Posted August 14, 2015 Looks good. I tried out Inazuma's LUT yesterday and it seems to fix that yellow cast as well. No more orange instead of red. Quote Link to comment Share on other sites More sharing options...

AaronChicago Posted August 14, 2015 Share Posted August 14, 2015 Nice to have LUTs working with the GH4.Who needs V-LOG now Totally. In my opinion there are VERY few flaws with the GH4 now. jonpais 1 Quote Link to comment Share on other sites More sharing options...
BrorSvensson Posted August 14, 2015 Share Posted August 14, 2015 Would something like this work for an a7? Quote Link to comment Share on other sites More sharing options...
Stronz Posted August 14, 2015 Share Posted August 14, 2015 What is this "EOSHD Cinema Profile" for the GH4? A settings breakdown for a current picture style or it's own original picture profile? I wasn't aware you could install custom profiles on the GH4. Quote Link to comment Share on other sites More sharing options...
Lukas Posted August 14, 2015 Share Posted August 14, 2015 I would really like to know how this works...If I understood correctly this is what happens:I have footage from the GH4, filmed with the specific settings (EOSHD Cinema Profile) that you researched and find best fitting for the LOG profile, which is applied much like a LUT is, which manipulates color so that it more closely resmbles a LOG profile, so you can then put a "real" LUT over it, which works better now, than before where you just had the standard footage out of the GH4. Right? (sorry for the long and confusing sentence) MattH 1 Quote Link to comment Share on other sites More sharing options...

Right? (sorry for the long and confusing sentence)Yes all correct sir.Also you can apply the LOG LUT in the transcode, then you get the LOG ProRes as if it has come straight from the camera as LOG.I prefer to edit ProRes to H.264. 4K bogs down too much in H.264 on my Macbook Pro.In actual fact you don't need to understand any of this, or anything about LOG and LUTs as the instruction manual that comes with the EOSHD LOG Converter has a beginners tutorial on this stuff.

Administrators Andrew Reid Posted August 14, 2015 Author Administrators Share Posted August 14, 2015 Who needs a Gh4 now I assume this works with a G7 too.No only the GH4 actuallyThe G7 doesn't have the advanced in-camera picture controls to make it suitable for the LOG Converter.

Andrew, so here's the thing, I don't actually buy you believe this, I've known you for a long time to tell you know better.Only thing I can think of is a mis-typing.

Andrew, so here's the thing, I don't actually buy you believe this, I've known you for a long time to tell you know better.Only thing I can think of is a mis-typing. Calm down sir. It is only a way of explaining it which makes sense.If it had a LOG profile in-camera yes you would get around half a stop of maybe 1 stop extra dynamic range as it would optimise the image processing for the sensor.The conversion in post gives you all the other benefits of LOG.

AaronChicago Posted August 15, 2015 Share Posted August 15, 2015 Is there an advantage to turning a Rec 709 image into LOG, and then adding LOG LUTs, instead of just adding Rec 709 LUTs to the "Natural, Portrait" profiles? Quote Link to comment Share on other sites More sharing options...
tosvus Posted August 15, 2015 Share Posted August 15, 2015 Thanks! I'm looking to get a new camera fairly soon, and owning the gh3 (and a crapload of m43 lenses), I am mainly looking at m43 cameras. Obviously the gh4 is high on the list and if I get it, I will be getting your bundle. I did buy your shooters guide for gh3 also, and that was very useful too!
