Default S2Pro exposure test

Being a photography nut, I wanted to get an idea about the response of the Fuji S2 Pro to exposure, and to get an idea where the highlight limit is.

The highest value the camera records is 251
Interesting. I did something similar with my 602. BUT I looked at the image file (bitmap) or conversion, with a hex editor and took those values, as they represent the real data range stored on the card - I saw FF. Is this what you did?

The real question is does your 251 (FB in hex) represent your white clip level, and my cheaper 602 have more headroom between 251 and 255?

If you put a fine line cross on your white patches, can you still see it at 251? After all, inability to see highlight detail IS the problem, not the apparent digital brightness range.

I just read the white value in the Info box in Photoshop.
Yes, The white line does show. Thanks.
251 is the white clip level.

I don't know how to do that.
