    Hi Chris enjoying the podcast to Niagara, in southern Ontario. My thoughts about about your image selection is in response to Rob’s question with regards to contrast. The image selected represents a very narrow dynamic range or contrast.range. Always a great show!

    Chris, I went to the PodTrac survey and gave you an excellent rating on all the appropriate questions. After many pages into the survey, there were many questions that had no relevance to your podcast or website. A lot of the questions requested information that I don’t care to share. At the end of the survey, it required my name. That’s when I bailed out. Sorry you did not get my excellent ratings. PodTrac may be one of the larger web advertising and survey companies but I would suggest that you look to someone that can do anonymous surveys that are specific to your product. I don’t have the time or interest in giving PodTrac all of this information.
    I will continue to enjoy your podcast and your contribution to Leo on The Tech Guy.

    Ron, thanks so much for filling out the survey.

    I’d be concerned too, if after the questions a survey would ask identifying information from me.However, giving your name on the last page of the survey is a) not linked with the survey and even more important: b) it’s entirely optional. And it says so clearly on that page. Even if you gave your name at that point (which you don’t have to), this would not be linked with any of your answers in the survey. It’s for Podtrac’s advisory board where listeners might receive further questions about other podcasts.

    If you stopped filling out the survey at that point, I believe the answer given actually count.

    I hope I was able to clear up this misunderstanding.

    Chris

    I agree with Terry, the image primarily falls into zones 7&8.

  • Mark Soderlund

    The photo shows what you explained when you were talking about when you described low contrast pictures.

    Two stops of Contrast?

    I also agree about the fact that the picture refers to the low contrast pictures.

    Dear Chris,
    Of course, your picture this week is illustrating a case of a narrow dynamic range, perhaps two stops.  However, it is my assumption that the numerical dynamic range, the number of bits representing brightness in the image is not dynamic.  Is this true? If I have a narrow range of brightness in the exposure, will I have all the information contained in only a narrow range of bits.  By way of example, if  I have 8-bits of numeric dynamic range (real sensors have more) with possible brightness ranging from 0-255, could an image such as the one you have here have values within the range of say 128 to 136, hence only 8 possible levels? I guess seeing these discrete levels would formally be referred to as quantization noise.
    Thanks for any response, love the show.
