I took a few extra items on my trip, not knowing for sure if I was going to use all of them. Here is the trip report:
For the first time since I bought my tripod, I really appreciated taking that along on an outdoor shooting. There were many instances when I had to open up the aperture, thereby causing a reduced shutter speed, and I did not have to worry about camera shake. I guess the alternative is to pay a lot more to get a brighter lens. There you go, buy a tripod if you are tight on lens budget!
I brought along my camera stand, studio umbrella, and two flash guns. I actually had a chance to use them when we were shooting portraits because someone forgot to bring along the club's light stands and we had to improvise using whatever we could lay our hands on. I also got to do off-camera flash shooting in a few outdoor instances.
My computer was also put to use. I was one of only 2 people who brought a computer. I used it to show a few people how to use Adobe Lightroom. It is a great software and it is growing fast on me. It was pure delight to be able to share it with other enthusiasts and seeing the excitement on their faces when they see what they can do as well.
What I also brought, but didn't put to use was my Expodisc, which would have been absolutely ideal for the rain forest hike for which we drove off-track for 25km and hiked 1km just to see the Ada Tree, which is a 300yr old mountain ash. It was not possible to get the correct white balance in that environment without the Expodisc. I left it behind in the 4WD when started the hike to the Ada Tree.
