My camera has three settings for compression--normal, fine and superfine. Is the only real difference how many images can fit on the memory card (most with normal, fewest with superfine), or is there a consequence to the quality of the images? The manual says superfine is for higher quality images, but I've read different things that perhaps contradict that.

If you've ever worked with photoshop (or any graphics program), you will notice that you can output jpeg files at different levels of quality. What is being varied is how much compression is being applied.

The 'Superfine' level in your camera is applying the least compression for the sake of maintaining as many of the natural pixels. When a jpeg file is compressed, it uses a scheme to group similar pixels together but through this you lose some definition in fine lines and other details.

Unless you are desperately in need of the extra space on the memory card, I would always suggest shooting in Superfine. It just gives you a better quality file to work with later (print or post-processing).

Keep it on superfine, the quality is better. Memory cards are not expensive anymore, it just isn't worth it.
On some photos you may not notice it easily, but others could be pretty much ruined.
Always take your photos at the highest resolution and best quality your camera has to offer. If you take a really GREAT photo and you want to enlarge it, you would regret having used anything less.

Thanks--I think that's what I thought...
Anyway, there was a Black Friday sale at Staples which allowed me to purchase a 1 GB card and another 512 MB, so space should be no problem.

I think you would get the highest quality pics at the "Superfine" setting and the lowest quality pics at the "normal" setting.
Some would also have to do with what size prints you'd want also.
The "normal" setting might make nice wallet size pictures whereas the "superfine" might make nice 8x10 pics.
You should always take pics at the highest resolution setting your camera affords you. It's easier to make them smaller than it is to make them larger and still look good.
