FujiFilm FinePix S5000

This is the camera I used to take the photographs you see on this site. Although not shown, I use the lens adapter as a "protective" barrier for the lens itself. In some of the pictures, the corners are dark and a circle of darkness can be seen enveloping the photographs. This is partially due to the lens adapter. A lack of a lens hood also contributes to this problem. It also seems that this effect is noticeable when zoomed in on an object at the lenses maximum, which is 10x.

A Data Sheet for the camera is available.
Here is the Manual.

You can use this free EXIF Reader to see the technical information about the photographs. Time, Date, Apature, Shutter Speed, etc...

You can also make use of the EXIF Reader to view the photographs themselves. I would strongly recommend using some other viewer, other than your web-browser, to view these photographs. A web-browser is probabally the most inefficient form of a graphics viewer.

Try the DPEX image viewer. It's free.
