    Now I wish I had some visual evidence to show that diesel can burn rather furiously when sprayed directly onto hot coals.

    It's just a little comical that you are criticizing others in this thread on how they might critique hypothetical photos. I couldn't care less what you think about my personal criteria for evaluating a photograph to be honest though, or whether you think I or anyone else here is qualified to do so.

    Diesel and other kerosene products have a higher flash point than gasoline products. The Flash Point is the temperature at which the vapors can be ignited. Above their flash point (126 F for diesel) the rate of flame spread is similar to gasoline. If the guy in the video had tested in ambient or fuel temperatures above 100 F, the jet fuel would have lit just like the gas.
    Gasoline has a flash point of -45 F, so it is virtually always above the flash point.

    Jet Fuel Fire 'a monster'

    I am my own worst critic which is why I rarely post any of my photos here. I am no expert in judging photos, but I like to believe I can tell a good shot from a bad one. Composition is the first thing I look at, distractions from the main subject, then focus...all the obvious things. I don't know if I could tell if a photo had been over processed or badly lit or not, though I know sometimes less is more. I know I have seen some which I thought were, but I don't know whether I was right in my assumption or not.

    You could spend some spare time independently studying art, particularly if your study materials lean towards contemporary examples of photography. It's not terribly difficult to pick up.

    A photograph has to be meaningful and full of life. Not every picture is considered as photograph. The photograph has to focus an object and has to tell about that object.
