x90 Av mode problem

sazzie · 10-22-2011, 01:03 AM

I am trying to capture a basic narrow aperture shot of my little boy with an out of focus background and have turned the dial to Av and set the aperture to between 2 and 4 depending on the shot. all the results seem to capture him and the background in full focus--ie ap seems to be wide open. am i missing something?

Wide open means a shallow depth of field, so it actually sounds like everything is working as intended

Plus, the x90 has quite a big of DOF to begin with because of the way the lens is designed.

The bad news: Due to normal technical design constraints inherent to that model camera it's far from ideally equipped to achieve the pictorial results that you desire.

Think of the X90 as a general purpose, versatile, albeit simplified, photographic tool primarily aimed at the needs of a mainstream-user audience; whereas the more tech-oriented design, featureset and capabilities required to effectively drive the outcomes that you seek (meaning: deliberate and specific artistic control), can only really be delivered by geek-targeted models.

The good news: No prob. Learn to adapt to it and enjoy what you have, because if you permit limitations like that to hinder your overall photographic experience, then you've completely lost the plot and no camera in the world would ever be good enough.
