    Step 1) buy used

    Step 2) review it yourself

    Step 3) ask yourself, "Do I like it?" Yes -----> proceed to step 4
    .........................................................No -----> resale it and go back to step 1

    Step 4) ask yourself, "Am I ok with a used item?" Yes -----> proceed to step 5
    ...............................................................................No -----> resale and re-purchase brand new

    Step 5) Enjoy!

    I had the unfortunate time of learning about this when I opened my Etsy shop. Data is king. It is why Instagram regular posts no longer perform and everything is in favor of Instagram reels, same with Youtube shorts, etc.

    They can quantify:
    how long you spend watching a video
    if you watch it to the end
    if you re-watch it
    if you click the call to action link/button
    comment
    like it
    share it
    etc.

    Speaking of fancy graphics, please click here:

    stolen from: pynomo.org/wiki/index.php/Photography_exposure

    Some theory for @CrashpcCZ in the link:

    "This example illustrates how exposure in photography depends on factors: latitude, time of day, day of year, weather, composition. It relates these to camera settings: film speed (e.g. ISO 100), aperture and shutter speed. The mathematical approach and model is taken from book written by V. Setälä.[1]"

    The above reference shows that there is far more to exposure than the settings of the aperture and the shutter, bastardized by ISO on one's camera ...

    One of these would be nice:

    From the link:

    @bobn2 has written:

    So, we see that if you have some given scene luminance, the relationship between the two controls and exposure is:

    H ∝ t/N²

    That's not a triangular relationship.

    Agreed ... and Exposure Value a la Wiki is log2(N²/t) - no triangle there either :-D

    Wrong quote. What is a triangular relationship anyway?

    Being factual, Idid not claim the theory to be truthful, right, or actually working.

    But it is here, obviously. Exposure triangle is everywhere around the internet. Tens or hundreds of publications.
