Question: RAW vs JPEG File Quality!?
If I shoot in RAW with my Canon Rebel XT, and then convert the files to JPEG, will there be a quality loss/gain than if I were to shoot in JPEG originally!?Www@QuestionHome@Com


Best Answer - Chosen by Asker:
I think you are asking which jpg file would be better to use - one directly from the camera, or one you create yourself from the RAW!.

Generally, I don't believe their would be a quality loss/gain!. By that I mean I think most compression algorithms are not too different, so one is not more likely than the other to drop a lot of info!.

Depending on how you process the RAW, yes, you could have a different jpg!. Cameras do convversion from RAW to jpg with a set of parameters for saturation, hue, etc!. If you take the RAW file and Directly put it into an editing program like photoshop, it will have a different conversion scheme and a resulting different jpg!.

I only shoot RAW if I intend to edit the photo!. So for portraits/people shots, virtually every shot is in RAW!. For sports, it is all jpg!. Everything else I make a decision before I take the shot!.

Ken Rockwell is a professional like a million other professionals!. He has some good ideas, some not so good!. He has a lot of fans and a lot of detractors!. Use him as "A" source of information, but not as "THE" source of info!. I think he is right on in this one!.Www@QuestionHome@Com

JPEG, even if at maximum quality, produce a quality loss each time you save it!. To shoot directly in JPG is not a good idea, because your original will be already not in a good quality!. If you shoot in RAW you can always choose to save the RAW file as a JPEG, but you can't go the other way around!. RAW files will always be better quality!.Www@QuestionHome@Com

NEVER ever use JPEG's apart from attachments to e-mails!.'Raw' is the only way to take photographs with a digital camera!. All cameras take a raw image, however the cheaper ones reduce this image straight away to a JPEG!. This reduces the size of the image!.

Letting your camera 'decide' what is OK and what to throw away is a bit silly!. When an even expensive camera stores the image as a JPEG, it has already thrown away 2/3 of all the information!.

If you shoot in RAW, you'll never have to have 'blown-out' highlights!. Editing (in Photoshop) is saved as a 'sidecar' (It stays with your image!. Your original stays pristine, no matter how often you change things in RAW mode!.

I never use JPEG's!. Every time you try to save a JPEG, the program tries to make the file smaller!. Each time more and more information is thrown away!. I save all my images in RAW mode!. If I need to send high quality images, I SAVE AS a TIF file!. (Large, but everything stays intact!.)Www@QuestionHome@Com

EDIT
-------
That's exactly what I said GLADIVS!.!.!. Ken Rockwell is "a" professional!. I don't worship at the Church of Rockwell more than anyone else and I never declared him the final authority on anything!. But this particular op-ed text on raw vs jpg is good because he includes links to opposing opinions and freely states that raw is not for him but does have a place in some situations!. It seems to look at the issue from both sides giving fair play to both - which I will agree he does not always do!.Www@QuestionHome@Com
