Taal Volcano's last eruption was October 1977 but it started displaying abnormalities since October 2004. It was taken last month, June. Yes, the sky was very hazy then, there was a moment that we can hardly see the volcano because of the fog. I waited until lunch time so that I can I have a clear view of the volcano.
I was using my Olympus E-510 and 40-150mm lens.
