Re: Lisbon Moonset.
An absolutely georgeous photograph. As an amateur photographer, it would be useful to have, if available, information on exposure, digital or film sensitivity and photo equipment used. Is such a thing possible?

I believe that APOD generally includes this information when it is supplied by the photographer but I don't think it is a requirement. It would be nice to know though.

It is a stunning photo. I copied it so I could use at as wallpaper later on.

If you save the full size image, you can access the EXIF data using a program like Microsoft Picture Manager (File > Properties > Camera Properties > More). This does not work on all pictures, but it does on most, if they haven't been resized by a program that ignores the data.
Believe it or not, the picture was taken with a simple HP Photosmart C850 (probably on a tripod), a relatively cheap prosumer model.

Good info, iamlucky13. Did you know that even just plain old Explorer can show the embedded information from within photo files, known as "EXIF info"?
1. Save the file to a temporary folder.
2. Click the right mouse button on the file in Windows Explorer.
3. Choose Properties.
4. Click on the Summary tab along the top.
5. Click on the [Advanced >>] button.

I did not know that. I think this may be a new feature added to the XP version of Windows explorer, because I don't recall stumbling across it on W2K. Thanks.

I did not know that either, so I tried it and it certainly works.
As a result though I am now confused, as the explanation to the APOD of March 24th 2007 states the picture was "recorded on March 20" and thus by implication (and the subject matter) that was March 20th 2007. The date it was taken is however given as 1/11/2002 in the information. Is there a reason for the different dates

The date on the guys camera was never set. He probably changed his batteries and never bothered.
