Tonight, we met with friends at Les Joulins Jazz Bistro in downtown San Francisco. We enjoyed some live Jazz to go along with our late-night dinner and drinks, and during their first break, had a chat with the band.
Bridget offered to sing a tune, and the band agreed!
She sang “Bye Bye Blackbird,” and sounded great! They told us we could come back anytime and perform. Very cool.
This particular venue had terrible lighting for photography. Most of the light was actually behind the band, which made things pretty tricky. Pushed my gear hard to get this shots, as you can see below:

This past Saturday evening, we were invited to a friend’s house in North Beach for some cocktails. We met lots of new people and had a great time. The hosts asked Bridget to sing a couple jazz tunes with Chris on the trumpet, and set up a spot on the roof for the performance. Ambient light was provided by…nothing…except for some hanging, incandescent, decorative lighting. Photographic yikes!!! I had one SB-900 to work with, so I set up my camera in manual, cranked up the ISO, set the flash to fire at rear curtain, and draaaaagged the shutter to get as much ambiance as possible, trying to make sure the little event looked like it happened on some sort of rooftop and not in outer space. As I uploaded these images to Lightroom 3 Beta, I was amazed at how well the new noise reduction tool worked on these photos. More on that in a bit.

And then….there was Alex:
Alex sang something interesting. Yes, very interesting. And Chris did his best to keep up with him on the trumpet. Here was their audience:
We headed back downstairs after the performance and enjoyed some drinks. Bridget and I brought a bottle of Absinthe, a spirit that was banned in the US for nearly 100 years. It’s some potent stuff for sure, and cannot be enjoyed without a good amount of dilution in water. Bridget made me a great mix by pouring ice water through sugar cubes on top of a specially made spoon into an ounce of Absinthe. The green alcohol turns a milky white as you pour the water in, which I believe is the result of releasing the herbs that the spirit is distilled in.
Adobe Lightroom 3 Beta: Noise Reduction
For a few days now, I’ve been using Lightroom 3 Beta to handle my processing needs, and so far I’m really impressed by the new features they’ve added. One of the highlight features for me is the new and improved noise reduction tool in the develope module. The noise reduction tools available in Lightroom 2 are just sorta-kinda ok. It looks like Adobe really worked at improving noise reduction this time around. As of now, luminance reduction is not available in Lightroom 3 Beta, so I’ve only had a chance to work with the improved color noise reduction slider. But boy does it work! Check out a couple of 1:2 crops from the first image I posted above that demonstrate the new color noise reduction’s effectiveness in Lightroom 3 Beta:
You can see a drastic difference in color noise between the two crops above (cropped from the upper left part of the frame from the top image in this post). The color noise reduction algorithm employed by Lighroom 3 Beta is extremely effective. In the image on the left, color noise was virtually gone at a mere 19% reduction setting.
That’s all for now!
Ah, good times…..
