Hi guys,

Please excuse the shameless plug (I hope the mods are ok with me doing this )

We just launched a new product called Cinelog which works with Adobe Camera Raw and most raw video shooting Canon cameras, plus the Digital Bolex and Blackmagic Cameras.

Full info is on our website www.cinelogdcp.com

Unfortunately this release isn't a freebie (and yes we know there is something similar available for free) but Cinelog is true log space conversion for Magic Lantern Raw and other DNG based video and comes with a comprehensive LUT pack and guide.

If you have any questions or want sample frame conversions to test gradability let me know using the contact form.

I was very amused by this form the site: "Cinelog 2.0 is a pure, mathematical, logarithmic transformation curve"

I have never heard of a log-curve that wasn't mathematical. A gamma curve, too - is mathematical and logarithmic.

Not to mention a TRUE Log Space conversion. What is a FALSE Log Space Conversion - LOL

LOG is a super-hyped word these days, taking advantage of users' inexperience with the word and meaning of it.

Also... using a LUT to access a logarithmic boost of linear light is something that is half.way dangerous as it clips (clamps) the signal @ 0 and 1. So proceed with caution. Whereas if one would create his 'own' log space via curves in i.e. Resolve, he would not clip or clamp @ 0 and 1.

Logarithmic is utter standard in math. And NOT something out of the ordinary.

Unfortunately, when dealing with images - Logarithmic is used to generate money off of the laymen !

To get a basic understanding of Log, read this:

http://en.wikipedia.org/wiki/LogarithmNot saying that logarithmic processing isn't of importance in color grading, it is... But every time you apply gamma to an image, you a basically applying a logarithmic curve to it.

Gamma is a power-function i.e. yourImage.XYZ = pow(yourImage.XYZ, 2) ; Raising yourImage.XYC(Red, Green & Blue Channels) to the 'power' of the exponent which in this case is 2.

Any value above 1 darkens the image. Lowering the exponent below 1 would basically brighten the image and 'Put it into this so-called LOG-Space... Combining multiple power functions will further influence the beloved 'Log Space' and produce diff. results.

Sorry to get grumpy on this one but I hate when standard math. is being sold off as astronomical NASA Surgery !
