    NIce... there is something i will like to ask on the photo...
    Anybody can explain to me the technique the photographer is using to take the photo?
    Because i see the shutter speed is at 25sec and f stop is at F18 which is not commonly used in this case... I am puzzled.
    Is it taken in a very low-light environment?
    Thank you.

    why not commonly used ? Product shoot common to stop down for dof... most likely using continuous light source, or could be using a technique of light painting to do product shot like Harold Ross

    He using a zk lens wor! Seriously, the Zk's render colors and saturation in such a nice and punchy way, my DA limiteds all pale in comparison (actually looks quite yuck to be honest - too much green and dull looking).
    I say the lens is the soul of a camera. What about the body? Well, it's just the body...

    f18 to shoot a pomegranate? Strange, unless he is doing something exotic like what flowerpot said.

    But hey what do I know about product photography~

    I suppose so.

    F/18 is used to have greater DoF, then because of the low light environment, 25 seconds is needed to get optimal exposure at ISO200 (for best IQ).

    Might just be that he did not have a brighter light source (Eg. window light) so just stopped it down and use a tripod.


    BTW, the focal length says 100mm.

    Is it me or is it not sharp at 100% (movement blur)
    Nice colors and composition nonetheless

    I know: 18/3.5, 21/2.8, 25/2.8, 28/2, 35/2, 50/2 (Makro), 85/1.4, 100/2 (Makro). All running low...
    In other words: 50/1.4 cannot find new anymore.

    I think can still find the 50 in eBay. Not cheap.

    It is so damn hard to focus accurately manually with a 21mm that is it any wonder the shooter used f/18 to maximize DOF?

    anyone knows where he would be focusing when using F18, then?
    or where would you be focusing on if you had to make this shot?
    trying to learn...

    Oh yes. I just found some. Not cheap indeed. 50% more than what I paid for the cheapest found...
