    did manage to get a good dof after getting a +4, can give me suggestions to improve?

    denizenx, as usual, please don't go spewing rubbish.

    thoa_rs: Shallow depth of field is not possible with consumer DCs.. it is a limitation due to the small CCD. A closeup lens only decreases your minimum focusing range, and allows a larger magnification.

    YSLee, don't be rude.

    But anyway, denizenx, you are wrong, big time!

    Small CCDs don't allow a good shallow depth of field. And the Hoya closeup lens are for macrophotography only.

    nah... the DOF is not shallow enough to my liking. That's the in-built limitation of digicams. The background still looks distracting.

    couldn't really get the flower sharp enough cos it was very windy... will try again soon.
    any tips on how to achieve shorter dof for portrait shots?

    Try shooting at the longest zoom. But I think the aperture will decrease as you zoom.

    yeah i've been doing that, the dof decreases that way.

    wow how did I miss this... no wonder so much animosity from yslee... ho well

    well I did ask him if he was shooting purely flowers and stuff..
    the +2 +4 do kill DOF a lot, since they limit image depth..
    and, sigh, I was trying to be application specific... from my experience with a +4 on a 75-300mm film and digital 38-380mm, it fits the bill quite well...

    hmm this I tried when I got home...
    a tired n pissed me..
    38mm +4 c2100uz on tripod,
    so the face a bit big... dunno if +2 is as powerful... I dun have it..
    I know the nose is not fully in focus either... but it illustrates the point...
