Hey gang. Thanks again to Clara for putting this together. I had a really good time, and it was great meeting everyone. When is the next one?
My Pics - Either I have way too many dead pixels, or my sensor really needs to be cleaned. I wasn't too happy with my results, especially in color. I'll post a photo when I get home and maybe one of you can tell me which it is.
It was no big deal, really. Me and John Setzler were shooting some pics of the fountain I posted an image of below. While we were shooting, a police officer informed us that tripods were not allowed on Capitol grounds. I actually did not realize we were on Capitol grounds at the time, but it would not have much mattered - I also did not know that tripods were not allowed in the first place. The officer was very courteous, though.
We folded up the tripods and continued shooting. In the shot below I used my backpack as a base and triggered the shot with the self timer.
What REALLY happened:
It was no big deal, really. Me and John Setzler were shooting some pics of the fountain I posted an image of below. While we were shooting, a dozen SWAT officers surrounded us and yelled at us to 'Get down! Put your hands on your heads and lie face down on the ground!!!' Since the ground was muddy, and since I had my new $500 jacket on (I thought I'd off to fellow DPCers), no way was I going to lie face down on the ground. Then I thought how fun it would be to take a picture of the SWAT team's weapons aimed at me, so I turned my camera toward the nearest visible semi-automatic weapon.
Suddenly, the sound of a single gunshot careened through the air. My camera went toppling to the ground--or almost did. Setz doved and caught it just before it fell into the gurgling water near my feet (thanks John!).
The officer yelled again, 'Put your hands on your heads and lie face down on the ground!! Now!!!' We really had no choice this time. Luckily, John was still on the ground, so I lay down on him and was able to protect my jacket from getting muddy.
Instantly, nine of the SWAT officers ran to our position and pointed their guns at our heads. I was sweating profusely, and Setz was breathing heavily (the result, no doubt, of my weight on him). I said to John, 'To think our DPC meeting would end like this!'
One of the officers suddenly stepped back a few inches. 'Did you say DPC? As in Digital Photography Challenge?'
'Uh, yeah!' I quipped brightly.
'Hey, I'm a member, too!,' noted the officer. The guns suddenly vanished and we were suddenly all smiles. 'Maybe someday I'll get a ribbon, but I've got to learn how to use depth of field properly. I'm also thinking I need to add some drama to my shots somehow.'
'Right,' I agreed, 'I think we could all use some work in those areas.' By this time the other officers had backed off and were headed to the dark, gleaming SWAT van I suddenly noticed was hidden in the trees.
John stood up. He was wearing a T-shirt made from his Liberty and Justice shot. It was covered in mud, but still startling in its photographic perfection. 'Hey, cool!' said the officer, 'how did you get that shot?' John proceeded to explain, but the officer stopped him. 'Sorry, I'll have to ask you later. I gotta go.'
As he walked away, he turned one more time to us and said, very courteously, 'By the way, you're not allowed to use tripods on the Capitol grounds!'
'Okay!' I waved back. We folded our tripods and continued shooting. In the shot below, I used my backpack as a base and triggered the shot with the self timer.
Hey, maybe you should consider a career as a freelance writer as well!

just a quick post of a shot I got. I just thought this was neat, even though some of the hot spots were burnt out, I like the clouds. I am now going to sleep. I haven't slept since thursday night. Just got back to Oklahoma. this is rambling. thanks clara. thanks everybody. lets do it again.
Okay okay, so I've been a bad boy. I haven't really had the opportunity to do any post processing, but I know I need to do it soon. Only a day left for the basic challange.. oh what the heck, hold on a sec...... Here we go... 2 hrs later.. did some cropping and a little playing around in PS, still learning, but here we go.
My start for the DC portfolio, still have a lot more to review and post process. I had a great time out there, needless to say when I got home, I was so in the dog house ;-0. Once she saw the pics she was a little less harsh on me ;). When I finally slept, it was 10am on Sunday and it was a short (2 hr) power nap.
We MUST do it again some time, maybe another city???? Hmmmm...
No.... sensor noise probably from a long exposure.. how long was it?
This was about 13 secs at f/10.

Put the lenscap on your camera and shoot at f/10 for 13 seconds at the same iso setting you used in this photo and then see what the results look like.
I think this is probably my favorite image from this event. The Lincoln Memorial has always been my favorite monument in Washington D.C. and I wanted to capture something nice there....

John,
Check this one out.
Taken with the Cap on. Looks bad to me. Still think this is noise?
Thanks,

I wish I could have made this trip. I was in DC last Spring to pick my eldest up from the airport as she returned from Luxemburg. I only had my little Mavica FD92 then, but here are some of my shots from that trip.

Shoot it again with the lenscap on and shoot at your lowest ISO option and shoot it for 1" and see if you notice any noise. Longer exposures definitely increase the noise on the sensor.

John,
Another taken, but this time at 1". Big difference. Looks like I have fewer bad pixels than I thought.
See photo
If there a big trick to cleaning up images like the first?
Is there any post processing or in-camera adjustments that are being made? I am surprised that a one-second exposure would have such hot pixels. I think for a baseline it would be great if someone could perform the same test with a different D100 to give you something to compare to.
I did roughly the same tests with my D60, and sure enough I have some hot pixels, but they do not show up significantly until I hit 30 seconds or longer.
I took two shots with no lens on, using the body cover, and extinguished all lights in the room as well just to be sure no light would creep in. The first shot at 30 seconds, sure enough, had a few hot pixels. I took a crop of the image (30 sec crop) where there happened to be two. They are pretty obvious.
However, at 4 seconds (4 sec crop) These hot pixels are not visible without looking very, very closely. If you download the crop and hit it with auto-levels in PS, though, they are obviously there.
Edit: As far as what you might be able to do to correct these images, google the term "Dark Frame Subtraction". This is a method that can be used to difference out hot pixels from an image.
