You're correct. I used just a part of your comments. Sorry about that.

Re: Log vs standard profile

Sometimes I'm quite snippy. It's because I attempt to keep the scope of things as narrow as possible to avoid misinterpretation or having "what ifs" applied to everything. Virtually all of this stuff has edge cases, and what the OP originally suggested was closer to using an s-curve in a gamma encoded space rather than levels in a linear one. That's the thing that causes shadows to go really blocky.

In this case the detail you contributed was extremely helpful though. It's probably of greater importance to the OP than any of what I mentioned, and I also thought it was interesting.

Re: Log vs standard profile

Color Lookup Adjustment Layer is news to me as I understand I cannot use 3D LUTs in CS5.

Because Resolve Lite is free and has Log Controls based on the film timing approach (offset and contrast) I might want to give it a try just because.

I must admit if I had film scanned I would love it to have baked-in log profile similar to the Cineon log.

You can also use Davinci Resolve lite but the log will be BMDfilm. From there you can generate a 3d out file for your specific image.

Oops! You will need CS6 or CC. In resolve you can convert to a tiff file then do the rest of your adjustments in CS5

I can apply a BMDfilm to VisionLOG 3D Input lut to a DNG file.

If you already have a log file you will not need to convert to BMDfilm log gamma.

You need the dcp log-gamma profile from color vision site.
Convert your raw file to dng
In the dng editor change the profile to the log-gamma it will be flat and looking like crappy.
Back to Photoshop and make your adjustments.
I use this workflow because I try to make my images look like film.
Yes I know I should shoot film if that's what I wanted but digital is cheaper and faster. I'm coming from Nikon F2 so I don't like the digital over saturated look. I hope I'm not hijacking.

Re: Log vs standard profile

Why do you want a "flat/low saturated image"?
