    About quantizing "noise"

    I have a CD with a demo track recorded with 8 bits, instead of the common 16 bits to demonstrate quantization noise. To my ears, it sounds like noise. High pitched noise.

    Dynamic Range versus Bit Depth?

    The maximum capacity of a pixel (the “full well”) is on the order of 80,000 to 90,000 photons on a modern sensor (actually photoelectrons—this is the quantum efficiency). Let’s be optimistic and say 131,072; to make it an exact match, that’s 2 to the power of 17. Modern cameras digitize the...

    Equations in my OPF posts

    At my end, the equation is perfectly legible and at a size similar to the text. I am using the "lights on" version of the site. Obviously, if I press "lights out", the text becomes negative but the equation does not.

    Capture One to support Hasselblad.

    Maybe a quick reminder on what happened at the time is needed. At the turn of the century, analog medium format was still the medium used by studio photographers, the ones paid to take picture for catalogues. Some worked with models (and appreciated the central shutter of medium format...

    Capture One to support Hasselblad.

    Capture One was written by Phase One and they decided that their software will not support Hasselblad, their direct competitors at the time. This is officially over: https://support.captureone.com/hc/en-us/articles/37246852336925-Capture-One-16-8-3-release-notes On a related note, the owner of...

    Survival of the unfit

    It is the first thread where Alamogordo was mentionned.

    Survival of the unfit

    On a subject unrelating to rolamite, I just learned there is a new candidate for New Mexico state legislature. Grace Nagamine has filed to run for NM state representative, district 51 (Alamogordo) as an independent candidate (DTS = decline to state)

    Why simple metering gives an average gray image

    There isn't much to discuss in the case of digital photography, which is what this particular section is about. For an engineer, the objective of digitizing a photographic scene would be to ensure that the whole of the information is recorded. That is actually trivial as today we have cameras...

    Flowers

    Ok. The top one is a true geranium or crane's bill (what people call geranium is usually a pelargonium). The blue one at the bottom would be scabiosa columbaria or pincushion.

    This what I understood. This is the answer I was looking for. Thanks.

    Why aren't new buildings built with local lumber?

    Flowers

    No, but there are quite a few.

    Flowers

    Yes, that's what it is.

    Between Water and Sky

    Yes, there is a tiny bit of black in the top of that image.

    Between Water and Sky

    I adjusted the perspective a tiny bit. The picture had the same problem as the other one a few days ago. I definitely think that there is a misconfiguration either in your camera or in the processing software. I find it particularly strange that the original has a black band on the left hand...

    What about this version of your picture?

    The Shape of Change

    The picture was taken with a Nikon Z8, which corrects such distortion automatically. Elements which are usually straight in a building are straight on the picture. It cannot be lens distortion. Then, you may look at the windows on the left-hand side. They have white bars separating glass...

    The Shape of Change

    Now I understand the title. I don't think curved balconies in that style are used in Europe. I don't remember having seen any.

    The Shape of Change

    Possibly. However, using rectangles as Doug showed, I still find that the vertical structures on the building are disposed as the sides of the letter "V".
