Cineon Log Color Space

I have read that any user working with a cineons, should not work them if they are still in the Log color space they were encoded in. I have read that the cineon file should be converted into "Linear" colors space first. Is this true for photoshop users as well? If so how do you know if it is in Log space or Linear, and further more how do you convert it from one to the other? A bit confused, any help would be great. Thanks

Please, if anyone can help me out with this I would really appreciate it.

If the cineons are log, then you need a lut to display them properly.
