Canon Elph S400 JPEG settings

My camera doesn't have raw output, but it does have three JPG quality settings. I just tested empirically to see how they correspond to the JPEG Q parameter:

Setting	Size	jpg Q
Superfine	1824k	98
Fine	1148k	94
Normal	580k	81

Given that quality of 75 is considered adequate in most JPEG software, there's some comfortable headroom here. Fine's 94 quality seems plenty for the photos to me and saves almost half the space. Then again with 1 gig of Compactflash for $83, there's not much need to economize storage. Bandwidth is still expensive, I'll have to remember to recompress the images before uploading to Flickr.
