Embedded JPEG file in 10D Raw

[$tephen]

As you will know with the 10D you have the option to save the embedded JPEG file at different sizes and qualities when using Raw mode. Now I use PS CS for Raw Conversion as a general rule, but never the Canon conversion software. I have always set the CFn8 Raw+JPEG to the largest setting. Now it occurs to me that if I set the JPEG to the smallest setting, this has no effect on the actual Raw image in CS except that the file size in camera is smaller. So my question is, if you are not already ahead of me, is there any point in using anything but the smallest JPEG setting which would be 0 in CFn8, as I never need to actually extract it using the Canon software.

Unless you plan to use the JPEG's as proofs to show people or get them on a web site or emailed to an editor as soon as possible, I don't see any reason to record anything but the smallest JPEG.

Thanks Scott for your quick response, this was my feeling on the matter too. However, how would I use the JPEG anyway? As I understand it these files can only be extracted from the Raw file by using the Canon Software, which I hasten to add is a poor substitute for CS or C1. Or am I just being naive ;)

This will probably start a big debate, but there isn't much visible difference between a RAW and Large Fine JPEG..

Some people shoot RAW + Large Fine JPEG, and batch strip them out of the RAW files with a utility such as Canon's FVU. Then they use the JPEGs and keep the RAWs as 'negatives'

If the image needs serious processing, then you can revert to the RAW file and use the superiour editing RAW provides..

You will need a bit more storage space, but really not a lot.. If you're committed to taking RAW files in the first place, storage shouldn't be a concern..

I have it set to the samllest jpeg.. When I shoot raw I shoot RAW.. I don't need the jeg.. but even if I do use the jpeg.. (for say an online gallery done in bulk) I still need to reduce the size.. so the smallest jpeg is more than adequate.

Ah yes the old Raw v JPEG debate :)

No, please do not start the RAW-vs-JPEG discussion again, we've been over that too many times already! :shock: And you're going off-topic here, the original poster did not ask a RAW-vs-JPEG question.

I've also set my 10D to the smallest embedded JPEG setting. I never use the embedded JPEGs. Unfortunately there's no way to disable the embedded JPEG altogether on the 10D.

Here is my take on the subject. Mind you I am a bit strange.
I set it for Raw plus Medium-Fine Jpeg.
The reason.
1. I obviously want the RAW file to work with towards a final product.
2. I need to give something to the models I work with (actually I don't have to at that point, but I get happier models this way)
3. PS 7.0 and CS do not have a slide viewer capability that is easy to use, so I need to use a different program to review the 459 images I took for example last night. Thus I use an old version of Ulead Explorer to display the images in a slide show. It needs something it can read, thus jpegs work real well.
4. It takes mere moments to extract the jpegs from the file.

Why the medium size.
Small is too small for me to catch more subtle problems with the images during 2nd and third runs during image choosing (during 1st run I am mainly failing images due to they are just bad)
Large is a waste of space, plus I only want the model to have an inferior image to the ones I have available. Medium-Fine is good enough that they can use for web portfolios and 8x10 prints for their print portfolios, but not for anything larger. Also in the unlikely event I lose the RAW file, I have the extracted Medium Jpeg for emergency backup, which is better then nothing and as mentioned good enough for an 8x10.

Thus my twisted logic for shooting RAW with Medium-Fine jpeg.
