High Dynamic Range Images

High Dynamic Range Images are made with your digital camera by taking one shot and bracketing the exposures. Most new SLRs can do this automatically now so it is really easy. You then feed the pictures to the HDR software (Photoshop CS2 or Photomatix) and it combines the multiple shots into one really detailed shot called an HDR. HDRs are not viewable on regular computer screens without an HDR viewer. The software allows you to "tonemap" the image so its viewable on a computer screen. Read more about it here. Its an interesting way to photograph because you don't know exactly what you have until you "develop" it with the software. I took some test shots around UNC on a blustery, nearly rainy day and they came out really nice.
You can see some of them here

Obama Calling...

Or rather me calling for from a house gathering of democrats in Chapel Hill and reminding the good people of Texas that they can vote twice in tuesdays primary. *I suppose only in Texas could you vote twice in one day. Roughly a third of the delegates from Texas will be selected tuesday night at 7:15 CST when the polls close by a caucus of voters who to qualify will have already voted in the election during normal polling hours. (How crazy can Americans make democracy, really?). So this afternoon a group of concerned yet-to-vote voters turned out to help remind the potential Obama voters in Texas to go to the caucus as well as vote. If they were supporters of the other candidate we were to wish them well and... move on. Most of the people I spoke with had voted early and for Obama and welcomed the additional information. So if my call sheets are any indication (who knows?) things sounded pretty good in the numbers I called.
