Wrong DPX ? searching for truth

Hi everyone

I’m working in small company. We are doing restoration of old movies.
At the begining we worked on 720×576 files.
But now we’ll work with 2K dpx files.
Some work we doing in Fusion.

But DPX files we get from scanner look odd.

I have read about internal structure of dpx file here
http://www.fileformat.info/format/dpx/egff.htm

Our dpx files have field "Transfer" (byte at offset 801) set to 01 (Printing density).
Is it the same if it was set to 03 (Logarithmic) ?

If I bring these files to Fusion, it automatically applys LogToLin conversion in loader.
I also enable viewer LUT and set it to 2,2 to compensate monitor’s nonlinearity.

Is it normal thing that picture has blown out highlights? highlights also have strange blue-green noise. Most of the white color is overbright.
And whole picture become very grainy.
I don’t think that this is how good picture must look like.
Get the same result if put files to the Nuke.
If it’s ok, then what is the reason of such highlights?

My question is how "right" picture must looks like?

I think it is possible there is something wrong at scanning stage. Some wrong settings maybe.
Without LogToLin and with LUT turned off, files look better.

Advice from experienced people needed. 🙂
May be someone can send me example of DPX or CIN you work with? or show it here. Please.

Some examples








Last two pictures I made from DPX file given to me by some vfx guy. He said "don’t worry about highlights". :rolleyes:

Sorry for my bad english
