Hello to one and all
I am (another) David, just joined and, having scrolled through BERNADETTE's post, I seem to have joined an extremely friendly bunch.
I will post a few photos soon - particularly of Viet Nam where we have just been on holiday.
My question: RAW and JPEG: I have a K10D so I can choose between the two (or have both). JPEG images never seem to be > 3mg. Does this mean that for (all) cameras with no RAW then there is no point in having more than 3mg capability (apart from the relationship between the camera, its sensors and its processor).
i.e. IS 6mb, 8mb, 10mb without RAW capacity just a case of marketing. Sorry to show my ignorance: I am new to digital photography but not new to photography (Canon A1, multitude of lenses and filters etc).
Many thanks
David B
Further to my question: yes, I have set the menu to take photos at 10mb (not 6mb or 2mb) David

A JPEG file is compressed, so when recorded on the card might be 3MB or whatever, but when opened into Photoshop(or another imaging program) will open up to 18MB or more.
A 10 MP (megapixel) camera will have smaller JPEGs than say a 14MP one and will fit more images on a card.
For best results, the K10D should be set to 10MP and *** quality (the lest amount of compression) if you are using JPEG. The K20D has an even higher level of JPEG file described as **** Premium.
RAW files have some compression but are lossless, that is, they do not lose any information. These files are much larger and fewer will fit onot a card.
Hope that helps!

Welcome David from another David although I prefer Dave.
If you have a big enough card shoot in RAW/JPEG, that gives you the choice to print straight from the camera and fiddle with the RAW files later.
That's what I do with my K200d

Welcome David.
You seem to be muddling megaPIXELS and megaBYTES. They are not the same thing. The former is the number of little dots used to make up a picture, the latter is the amount of disk space used to store the image.
The amount of disk space used to store your image depends on the format of the file you use. As John said, RAW takes up more space but retains more information. JPG takes up a variable amount of space depending on how much compression is used: more compression, smaller files but poorer quality. Try setting the camera on a tripod and taking the same photo using RAW and the three levels of jpg compression and then comparing the file sizes.
Having a bigger sensor (i.e. 14 megapixels v. 10 megapixels) mainly helps in two ways (1) you can make bigger good quality prints and (2) you can crop the image more drastically and still get reasonable sized prints.
Hope this helps!
Cheers, Kris
