    ...I made a test.

    I got myself the salt crystals we once had grow in a jar (for experimentation reasons), and also got myself a bit of ordinary sugar.

    I first photographed the salt crystals with my Sigma lens at 300mm in the macro position:

    1. and 2.

    Then I photographed the salt crystals with the reversed kit lens on, at about 24mm

    And then I went about photographing the sugar crystals in the reversed lens mode at about 20mm

    4.

    They are less cubic, more diamond-shaped

    To show how much bigger than the sugar the salt crystals are, here some sugar next to one salt crystal photographed with the lens reversed at 24mm

    With these photos in mind, I now begin to believe that it is sugar in Neptune000's_thread .

    kind of cool shots you got there, its neat seeing the sugar and salt next to each other. Makes me want to try out reverse macro a little more in depth than holdin the lens up to the camera and hoping to get a decent shot! haha

    Well, that has forever been the only method I can use! Thankfully I now have the Speedlite to help me, before that it was also hoping I'd be able to keep the camera steady enough (and it is black night outside).

    I never though I would get that up close and personal with sugar and salt. Cool!

    i like the very first ones ... the latter are a bit too shallow in DOF for the subject... but that is just my taste maybe.

    i think, they could all be dramatically
    enhanced by using a different background :)

    OK, you buy me a new desk? ;)
    And with the reversed lens "macro", there is no more DOF to be had.
    But hey, once you come round with the nicer new desk, you can bring the real macro lens, too! How's that for an idea!?!?!? ;) (And a day later I did photograph some sugar on a black cardboard, but in reversed lens macro, that cardboard suddenly gets EVER SO MUCH texture within that tiny, tiny band of focus, it is incredible). So think about it when you go choose me new desk, ok? ;) ;) ;)

    And that would mean you come round in your Audi to bring it here? Uh-oh. Must go clean those windows FIRST :oops: ;)

    Do you think that big salt cube in 3 looks "bizarre"? (I'm still into that subject... :roll: )
