I took WZ to see the Dinosaur Live exhibit at the National Science Center. Taking my Sony A550 with me since I knew the exhibit would be in a dark area and thinking I had a better chance with better shooting control than the Sony NEX. And I learnt a few things doing so.
Autofocus doesn't work well in the dark
To the camera, it's pretty much pitch black in the exhibit. Autofocus couldn't pick out any details at all, and the fact that I was using the F20 which doesn't strobe as a focus assist light didn't help. The solution would be to switch to manual focus, or as I figured out after a while, use a flash light to help your camera focus (I used my HTC Radar's flashlight for this)
Shutter priority is a better choice in the dark
One of the first things the
Semi Pro taught me when I first got my camera was that it'd be easier for me if I just used aperture priority in my shots, since usually when you're shooting with people you'd probably care more about the depth of field. And that has worked pretty well for me. But in a dark area, it's more important to control how long the lens is opened so you can control the lighting effect.
Fire the flash in rear sync mode.
Not really a new thing I learnt this time around, but just as a reminder from last time. If you want to take photos which shows the ambience of weird colored lighting in the environment, set you flash to fire in rear sync mode.
Remind your wife that it takes time to setup the camera to take nice photos when you don't have practice.
The night before I say my wife down and told her "Honey, I'm going to take the DSLR tomorrow when we go see the exhibit, it's probably gonna be in a dark area and I'm gonna need some time to tweak the camera and learn what's the best way to shot a picture in there. So it doesn't help if you keep complaining about why I'm taking so long for a shot."
Yes, I'll probably get killed if my wife reads this, hence WZ's expression is highly suitable for this tip. And if you don't understand what's the big deal about something like this, you're not married then are you? :P
