Brian asked me to take pictures of some of his Zebrafish. For comparison, these are about the same size as a Triple-A battery. They’re fast, don’t sit still, and stay too close to the sides of the tank. All in all, rather challenging to photo.

where did all the colors go?
Based on some of starfish235’s analysis on flickr, I decided to play around with a few of my own photos to see how various lenses responded to the chromatic aberration analysis. To quote from Bruce:
- This enhance view of the CA should be used to identify regions of the original (full resolution) photo where you should look for the effects of CA. CA doesn’t always result in a strong visible color tint in the original photo, but it often results in a general loss of sharpness and reduced resolution when a visible color shift isn’t readily apparent.
The following are a few examples:
The above picture was recently posted, and taken with my Sigma 150. The CA has been enhanced ~9dB. As you can see in the higher resolution image, the CA is fairly well controlled.
This image was taken with the LX-2 and also enhanced ~9db. As you can see, the CA is most defined at the edges (where you would expect), but also exists in parts of the photo you wouldn’t generally look for it.
I may post additional pictures later – if anyone has any requests I’ll be happy to post them.

For those of you who don’t know (or haven’t heard), the new version of Adobe Lightroom came out Sunday. My copy is still in the mail, but I’ve been playing around with the trial until my serial number arrives. All in all I’m really enjoying it, and the final additions from Beta 4 to 1.0 are, in my opinion, the two features I felt lacking in the earlier versions.
First, Lightroom now includes snapshots, where you can maintain multiple versions of your raw files as you work. The upshot of this is that you no longer have to deal with multiple xmp files for different versions of your files. Instead, you can maintain and adjust multiple versions – say one in color, another in black and white, and a third with a higher contrast setting. The second useful feature is a dust removal tool. What this basically means is that you really never have to send your images to Photoshop – Lightroom can basically serve as your one stop processing shop for RAW files of all types.
I think I’m going to like it.
I played around a bit with using the SB-800’s for macro stuff. The Carlsberg bottle was all I could find on short notice.
