Lost at Sea




Lost at Sea





I was feeling a bit down today so I though a trip up to one of my favourite places was in order, Formby Beach, and I came across this little beauty. It had obviously been in the sea for a while as it was battered, bruised and holed, but I thought it would make quite a nice shot. All I had to do was roll up my trousers and wait for the tide to come in. Now here’s a warning kids, tripods and sea water don’t mix! The sand there was very fine and as soon as the tide came in, sand got washed into the joints and locked them solid, looks like I’ll have try to strip apart tomorrow. Oh, and another warning watch out for the tide, I was on an outer sandbar, and as soon as the tide topped over a low point in the bar it flooded behind me, luckily I was on the way back in, but in about five minutes the water reached knee deep!

About the shot; It’s a HDR of three shots (-2, 0 +2) shot at F25 (you should have seen the amount of dust bunnies I had to clone out, I’m ashamed of how dirty my sensor is), then with stacked Hi-tech ND filters 0.6 + 0.9 (equivalent to 5 stops) @ 22mm (Canon 10-22). Basically to try to get the longest exposures possible, I think it worked quite well. I’ve got loads of them that haven’t worked, as the tripod kept sinking, and the waves kept moving the boat!

But after getting some nice shots and splashing through the waves I feel much better :-)

U.S. Ambassador Jerry P. Lanier meets with the group to congratulate them on their selection





Nineteen participants, representing 14 new Small Grants programs for 2011, gathered for a full day workshop at the U.S. Embassy on Tuesday, September 13, 2011. The projects were selected this year from over 396 proposals. The grantees represented small community based organizations working to solve problems of safe water, improved agriculture and nutrition, income generating, and health care support to People Having AIDS throughout Uganda.
Connie Hansen, the PEPFAR Small Grants Coordinator for Adult Care and Support programs, guided the grantees in how to work with the U.S. government in handling the fiscal details and reporting requirements of a grantee. The team of Ugandans also had a good opportunity to meet each other, share their community programs, and form a network of resources among themselves. There were two special presentations on Bio Sand Water Filters and a comprehensive approach to community development from two participants. U.S. Ambassador Jerry Lanier met with the group to congratulate them on their selection and encourage them to continue serving their communities.
