exomonkeyman Posted March 31, 2015 Share Posted March 31, 2015 Hello There EOS HD forums. A quick question, i'm interested in the A7S but i must ask about grading vs the 60D/5D cameras. I'm no colorist but my 60D with a (rec709) color profile, after cc i get this horrible color artifacts and degradation as i call it, where you can see the colors start smudging and looking grainy.(looking closely)http://cl.ly/image/2o083R0n3c2e?_ga=1.184071008.719058195.1402172166http://cl.ly/image/2n2D2I3w2L2W?_ga=1.111628610.719058195.1402172166How is grading in S-log2 any different than just shoving colors around even more like i already am on my 60D? And is the file format XAVCHD a better general codec for color correction than the canon codec?Or is there something i could be doing to stop this? Using impulZ luts. (Not a big LUT person) Any help would be awesome cheers. Quote Link to comment Share on other sites More sharing options...
Administrators Andrew Reid Posted March 31, 2015 Administrators Share Posted March 31, 2015 Take it by rec.709 you are using a standard Canon profile like Portrait or something on your 60D.Well S-LOG is LOG so a different league. It flattens the full dynamic range of the sensor and packs it into the codec. It grades WAY better than the 60D or indeed any of the Canon or Sony rec.709 profiles because simply put, there's more to work with in the image. Nothing is burnt or crushed or baked into the image. exomonkeyman 1 Quote Link to comment Share on other sites More sharing options...

(that's much closer to LOG, but still creates color smudging for the 60D) Quote Link to comment Share on other sites More sharing options...
Nick Hughes Posted April 1, 2015 Share Posted April 1, 2015 No, shooting 'flat' on a DSLR is nothing like shooting real LOG. I use VisionColor profiles on my canon because I like the look, but not because I'm squeezing a ton of extra details out of the sensor. exomonkeyman 1 Quote Link to comment Share on other sites More sharing options...

Guest Ebrahim Saadawi Posted April 1, 2015 Share Posted April 1, 2015 Did you try Neat Video? It's a magical solution for you problem.Here's after neatvideo plug-in: Untitled_000000.tiffIn fact, after that, you can even push the image and grade much further Untitd_000000.tiffThe downside is when you use it on an extreme example as your above, the image looks too clean, too plastic, so adding a small layer of grain back takes care of that plastickyness itled_000000.tiffEssentially, you replace the ugly colour breaking and ugly noise with fine good looking grain, or keep it clean without any artefacts if you like it.
