The image above is the "youngest" moon I've been able to capture, from May 19th, 2004 in the Davis Mountains. See details below.
I have a bigger thin moon page here, featuring more scenic moons. This page features the thinnest of the thin, those that are less than 24 hours from new.
This was my first shot after sighting the moon at 5:55 a.m. 7/31/2008. Photo Details: 1.3 second exposure, Nikon D200, Nikon 80-200 f2.8 ED AF lens at 2.8, ISO 800 setting, significantly cropped from original. Moon was 1.34% illuminated, 2 deg 17 min up according to The Sky. I have the new moon at 5:13 local time the next day, so that would be 23 hours 12 minutes from new. My last shot before heading into work was 15 minutes later, 22h 57m from new. See picture below.
Here's the report I sent to the local astronomy clubs: I was able to catch this morning's thin crescent moon from the south shore of Lake Woodlands. Aside from the annoying lights nearby, that turned out to be an excellent location due to its very low ENE horizon. First view was at 5:55 a.m., which I think means it was about (23 hours 12 minutes, corrected) from new. I took a series of images over the next 15 minutes. This was pretty easy in my 8x42 binoculars once I located it, and I could see it in the camera viewfinder (using 80-200mm f2.8 lens at 200mm) after 6:00 a.m., but I don't believe I saw it naked eye.
Above: 1/8 second with same equipment noted above at 80mm, moon 22h 57m from new. It was the last shot I took before heading to work. Picture was manipulated in Photoshop to increase contrast; the moon was much more difficult to see than the picture implies.
2/21/04, 6:17 p.m. Moon above is almost exactly 39 hours old by my calculations. Processed with Neat Image to remove noise & sharpen. 1/160 second, Nikon D100 at ISO 400 setting, Nikon 300mm f2.8 lens at f2.8.

I was able to view a thin crescent moon in the Davis Mtns. I drove around at sunset trying to find a place with the lowest western horizon. I set up my camera/lens/tripod on a road, and scanned for the moon in 10x50 binocs. Acquired it at ~9:08 p.m. CTD, age 21 hrs 15 minutes -- and started taking pictures. Right as it was setting into the trees a car came along and I had to move. I only had it for a few minutes, and I don't believe I saw it naked eye. Hard to remember in all the excitement... The Sky says its phase was 0.75%. When I got back to the cabin (*after a long walk and a ride back to my Van, whose battery I had drained) I loaded the pix onto my laptop. I about had a heart attack when I couldn't see the moon at all in the thumbnails and the first full-sized images I looked at. On closer examination, thankfully, the moon is indeed visible on a number of the images - just barely! Photo notes: Nikon D100, Nikon 300mm f2.8 lens, 1/60s, time 21:09:30 CDT. *See below for the dead battery story... Sky and Telescope has an even younger picture here.

*Dead Battery Story on the 21 hr old moon:
So anyway, I set up about 45 minutes before I got the shot because I was chasing the sunset to a) get my bearings, and b) figure out how much time I had before the moon set locally. I decided to put on some music to pass the time on this isolated mountain road... I decide maybe the music was a bit too loud so I rolled up the passenger window to help control the volume in case anyone was in earshot... and forgot to turn the key of the "on" position! My clue was, just as I was wrapping up, the music stopped momentarily when my hazard lights flashed. Dead battery, and I'm stuck a mile or two from my cabin. And, I'm overdue to get drift aligned for a night of astrophotography! But wait, I have a spare battery in the back (for powering all my astronomy stuff; wasn't using it since I had power where I decided to set up this trip). No jumper cables, though. Fine, I'll replace the battery and be on my way in a few minutes... I found a small multi-purpose tool in the glove box, and proceeded to disconnect the battery and pull it out. No small task with this little tool, I should add. Then I go to put in the new battery, and you guessed it, it's way to big to fit in the slot. I put back the old battery, and decide to try starting to see if the battery had recovered... Turned over 3 or 4 times but didn't catch. I ended up hoofing it back to the cabin using a tiny flashlight on this difficult mountain road to find my way. I imposed on my hosts for a lift back to the van, and ended up getting quite a late start on the evening's shooting. So, when you're set up out in the sticks watch your power sources! (And no good deed, e.g. rolling up the window), goes unpunished.)
