This thread is dedicated to all the long time Sony F3 lovers, owners, and shooters on the web.
I feel like so many of us have been trying for years to crack the secret of working with slog from the Sony cams – whether that’s the Sony F3, F5 or F55. Some of us have been more successful than others, either grading slog directly or creating a myriad of complex nodes in Davinci to get things “close” but still not “close enough”.
There are many who feel that working with slog is no big deal and that only a slight adjustment curve is needed in post to bring things back to normal. This is partially true, and in fact the way I had been working with slog back when I owned the F3 grading using curves straight off a Premiere timeline. But for a long time many of us have been looking for a proper way of unraveling slog to remove any limitations in the grading process and to get the image to a more “better” starting point for grading not to mention getting rid of that “Sony look”.
The discussion or idea around de-logging footage is not really that new especially since there are more FS700, F3, F5 and F55 users than ever. For slog2 and slog3 Davinci Resolve makes it easy to apply the right IDT and ODT transforms so that you have a very good base to start working with. Plus all controls actually work like they are suppose to. ie. The shadow control actually controls shadows, midtones adjust midtones, and highlights control highlights. But where is the IDT for the original slog you ask?
Well thanks to some dedicated Sony-F35-philes and mainly MacGregor, a member on the DVXUser community forums, there is now a ‘slog to cineon’ LUT available for the original slog that will give you a better start and better controls in Resolve for your grade. slog is found on both the Sony F35 and F3 cameras.
I take absolutely no credit for doing anything here! I am largely taking the work in progress that has been developing in the online community and sharing it here along with some of my own tests on some footage. I thought some of you would love hearing about it and want to try it out for yourselves.
Below are test results on some old footage of mine shot on the Sony F3 in slog 8-bit 420. Please post comments and let me know what you guys think:

The basic process is make your input LUT “slog -> Cineon” • Apply your grade • On the output node use “ARRI C Log -> Rec709″.
In my example however I incorporated the use of the Kodak 2383 print film emulation LUT and a 35mm film grain loop. If you decide to use any print film emulation LUTs you have to remove the “ARRI C Log -> Rec709″ from the chain. My process looked similar to this:
