First: thanks to everyone who works on making CHDK possible, very much appreciated.
On my SX230 everything works as described except the Override JPG Quality option. Whether I set this to Superfine, Fine, Normal or Off the resulting CHDK files are always about the same size and are always somewhat smaller than the non-CHDK mode Canon Normal files and much smaller than the Canon Fine files.
Close inspection of the CHDK jpgs does reveal less detail than the same picture at Canon Fine.
As an example I just took six pictures, tripod mounted, same exposure and zoom settings at the following settings and got file sizes (MBs) as follows:
Superfine - 1.88
Fine - 2.11
Normal - 1.85
Off - 1.85
Fine - 4.63
Normal - 2.33
The camera was in Canon Normal compression during the CHDK part of the test.
Is this a bug that could be fixed, or is it possibly user error on my part? I'd really like CHDK files of at least equal quality to Canon Fine. Thanks,
