During my quest to understand how raw files work and what are the benefits of using one format over another, I never really found out a clear definitive answer. So i decided to start this topic in oder to do so.
My fundamental questions are:
A) Which raw files DON'T have baked-in white balance?
B) Is there anything as logarithmic raw files?
And the answers I have found so fare are:
A) .ari files and Magic Lantern 14bit .dng files
B) I don't consider .MXF or .R3D files to be raw but uncompressed video therefore no. Otherwise I would say that the only logarithmic raw files are MXF files
Pretty much all other kind of raw files out there turn out not to be really raw as they claim. In my opinion, I found that working with a linear file was a safer bet against blown highlights and being able to truly change white balance and at least magenta/green shifts (unfortunately no blue/amber cast in lightroom for me, only magic lantern allows you to correct that in camera :D)
Maybe for you all the answer to this question are obvious, but I though it would be nice to have a little corner of the net with a clear cut answer to which camera does generate TRUE raw files (I am looking at YOU: RED, SONY, CANON, BLACKMAGIC )
Because, I would be pretty pissed off if i'd bought a sony f55 or a RED Raven or a Blackmagic Ursa or any other 10k+ camera and find out I can't truly change white balance in post e.g.: The lumetri panel in premiere does not do that. It only apply a azure/orange filter to the image to simulate white balance shift.
Last night I was looking on Vimeo at GX7 videos to see what other people were producing. For the most part it all seemed very casual, not much good stuff in there. But then I came across this:
First of all you should know that I've been shooting with my GX7 for almost a year now and I've messed around with the camera settings and resultant footage loads. So I pretty much know GX7 footage when I see it. The video above looks completely different to anything I've seen previously.I remember a phrase Andrew used in one of his videos regarding the BMPCC, "The camera has a very filmic response to mid-tones". And I guess this is the only phrase I can use to quantify what makes this footage look different.
If you look at the tags on the video above you will see a mention of "Tiffen Ultra Contrast 5". So I did a little more research and it seems these things had their hayday a couple years ago around the time when the GH1/2 and Canon rebels were popular. These days some people still use them even for high end cameras like the RED.
Here is the description from Tiffen itself:
I quite like the look that diffuser filters give and it sounds like the Low Contrast filter will give some of that look along with the softened contrast. Does anyone here have any experience with these and can make recommendations?
