I recently bought a Nikon D40x. For the majority of what I'll be doing JPGs will be fine, but occasionally I'm going to want to convert a color image to B&W. (For now I'm using iPhoto although I know it's not the best.) I have heard from a few sources that this conversion will work much better if I shoot in RAW and then convert. However, I don't want to fill up my computer hard drive with tons of RAW images that I won't need.
So my plan is to shoot all my photos in RAW but save them as JPGs, except for the ones I'm editing to B&W. Is it true that I can use a program called File Juicer to download JPG's to the Mac that the camera generates automatically when you shoot RAW? If so, will these files reflect the settings (white balance, etc.) that I have used? And will they be the highest quality JPG's, (as opposed to the "Basic" ones you get when you set the D40x to shoot RAW + Basic?). Can I then delete all my RAW files from my computer, except for the ones I want to convert to B&W?
Does the above seem like an appropriate method for what I am trying to accomplish? Any other suggestions? Thanks.
