Re: CP4500 has a RAW mode!

RAW file is a type without white balance, interpolation, sharping and anti-aliasing, and exposure compensation. If you choose to shoot RAW, generally this means you want to do post-processing on it instead of let camera to all the things.

Why you can do better than camera? because the CPU of your computer is much faster than the camera, and with the software on your computer you can have more fexibility to processing your image just like negative film.

What is more, RAW file has 12-bit color depth so the dynamic range is 16 times more than the 8-bit jpeg file. you can pull details from RAW file, which in 8-bit jpeg will be "white out overexposed" or "black out underexposed", this kind of EV compensation is the most important reason to choose RAW

How useful if the RAW mode in these cameras? I have noticed that
with my 995, the white balance if not exactly correct when using
the raw mode. I took an image on a sunny day and imported the RAW
file (converted to NEF with the V0.02 version of RAW2NEF) in
Photoshop using the NEF file plugin with WB set to FINE. Instead of
a nice blue sky I got an image with a purple cast over it. I don't
yet know what the results would be with my 4500 but if every image
has a color cast over it I consider the RAW functionality useless
