I never used to taking raw photo shot until recently I started learning to use manual mode instead of Auto. Raw only work with manual mode and other mode. Still learning how to control shutter speed and aperture plus ISO...That is very challenge for me that is because I am not ready for dSLR just yet. Anyway, I want to see how raw photo works with Aperture and I find a good learning experience how to change it to your taste. What I am confused about JPEG file...You can change anything with JPEG just like with RAW file. What did I miss something? For example I can change exposure or highlights setting with JPEG and RAW. I always thought JPEG file has very limit on how you can change it.... Raw file gives you unlimited way to change anything right? Like I said I am still learning to use Raw file from now on.
