Tamron SP AF 28-75mm f/2.8 XR Di for Canon

I don't have one but am fielding a question from a business client who does and I'm not sure his question makes entire sense.

Before I probe further (!) can someone tell me whether the 10D offers BOTH a RAW ONLY mode AND a RAW with embedded jpg?

Thanks!

The 10D captures a jpg automatically when you shoot in RAW. See this reference.

Ah, ok.
So it doesn't have a RAW ONLY mode.
That makes more sense of the question.

This guy is asking how he can remove the embedded jpg and my two questions (not to him, to myself) were-

Why do you want to remove it?
Can you shoot in RAW only instead?

Ha ha ok found out the issue.

He used to have a 10D and still has the manual. In there it runs through steps to remove the embedded jpeg. (Still don't see the point other than storage space but ok...).

He now has the 20D but the manual is in French (which he doesn't know) so he's still referring to the 10D manual.

And of course, the 20D doesn't embed the jpegs - it creates a second file. So the instructions in the 10D manual are completely irrelevant.

Mystery solved.

THANKS

Slight aside - is the 20D manual not available to download on the Canon website? I'd dl'ed and read the 10D manual before my camera even arrived : )

Why does he want to remove the embedded jpg?

If he wants to do it to save space on the CF card while shooting, the 10d will allow you to adjust the size/quality of the embedded jpg down to a minimal setting...

First thing I asked him was why he wanted to remove the embedded jpeg. Best answer I got was that it seemed to suggest that this was desirable from his reading of the 10D manual.

I've basically now told him that if he's worried about space issues when shooting he can shoot (on his 20D) in RAW only but that RAW with basic jpeg makes previewing quicker once he's downloaded images to the PC. Once he has them on the PC the only possible reason to bother deleting associated jpegs is a storage space issue and that disk space is so cheap these days that it's not really necessary.

I don't really understand the purpose of the embedded jpg, but it's there. It can't be totally removed with the 10d either. I set mine to the minimum size/quality just to save space on the CF card. Changing to this increased my card image capacity by almost 50%.

As I've never had the 10D I hadn't realised until this came up from him that the 10D did things differently from my 20D which creates a separate jpeg file.

For me the main use is for browsing a directory full of raw files. XNView displays the embedded jpgs and because of this is very fast for looking through an entire days shots.

I might be wrong but I think what Setz maybe asking is not why one would want a jpeg preview (the previewing convenience is clear) but why Canon came up with a format that embedded it into the RAW file rather than what the 20D does which is simply create a second image file that is a jpeg. Means one can use the jpeg for preview purposes and to decide which RAW files to keep and to process but delete it if desires once the conversions have been done, keeping only the original RAW file as archival.

That would certainly be the bit I don't quite get.

Hmmm... Maybe he really just wants to extract (vs. delete) the jpeg file. "Remove" can mean either.

Again, in XNView with 10D raws, if I hit the delete key while viewing the preview, it is the raw file which is deleted. If I move the file into my "process" folder it is the raw file which is moved. With a seperate jpeg it would require a lot of extra (and error prone) work on my part to achieve the same results.

The solution is of course software which treats the 2 files as one unit, but as I don't have seperate jpegs I've never looked into that.
