Hello all, new to this forum, lots of excellent info, learning many new things.
I have a question about the new Canon 30D I have, with the option for various size JPEG's, then it has JPEG+RAW in different sizes, then RAW only.
What does JPEG+RAW format do?

RAW files all need to be manually processed - it's basically you being the darkroom and making all the decisions. What JPG + RAW does is give you a JPG copy of the photo too so you can actually see the shots when you upload them instead of having to go into each one to process them individually first. It's a much easier way of deciding which ones you want to process and which ones you just want to toss or keep as 'snaps'. It's my primary use on my camera - although it does use a lot of card - Allows 239 shots/2Gb card on my Nikon D50 - less than half what .jpg fine allows. It depends on how much post processing you want to do. For starters, you may just want to put it on the highest jpg resolution and then graduate to RAW. You still have quite a bit of post processing capabilities with a high-resolution .jpg and they will still enlarge extremely well.

Hope that helps and welcome to Byte.

Hi Suzan, thanks for info, looks like I may need a bigger CF card.

Congrats on being a contest winner, nice scenic shot.

Suzan,
didnt your camera come with a picture viewer/browser?
I use Nikon view that is free.
As soon as you download RAW files with no processing at all, you can still view each picture and even view at 100% to see if every bit of the picture is in focus.
You dont even have to open the files, you are just viewing them from within the browser

It will certainly save you from waisting valuable space on you CF card with the extra jpg's if you really dont need them when you have a NEF file to work with.

Found I can view a RAW file on my 30D view screen.

Hi everybody

I recently bought a SLR 8 MP (Canon Rebel XT) with the option of saving files in JPG or RAW or JPG and RAW. I’m having essentialy 3 questions :


- I presume it’s normal when I choose the top quality picture, that JPG file end up with a 3 M file instead of 8 M file in RAW. Wich one should I choose if I want to enlarge some pictures ?

- And what size of enlargement should I expect to be acceptable with this SLR ?

-If RAW exist, if it is a very good output and probably the best for enlargement how come most of the photo lab don't take them. They take TIFF files wich are very often larger files than the RAW files for the same picture.



Thanks

I decided to shoot in RAW+JPEGat the same time, then I can use JPEG right awway, but still have RAW in case I need to work on it.
