Re: How Do You Do It and Does It Work?
The size of the files also varies according to the information kept in them. RAW has significantly more information for example it keeps the orginal photo as shot as well as any modifications - this is why you can revert to the shot photo. JPEG and TIF does not hold this information. Having been a computer programmer for 40 years I can assure you that no file is equal to another unless it is a straight copy - and that applies here. as clearly a TIFF file is not the same as a JPEG which is not the same as a RAW
The CPN article explains file compression more eloquently than I can http://cpn.canon-europe.com/content/education/infobank/image_compression/lossless_and_lossy_compression.do.
I understand what Stephen is saying and agree with him except for the line about RAW not being compressed - it is, but a lossless compression - simillar to computer ZIP files
