Embedded JPEG's

[Gary T2]

I am a new 10D owner. What is the purpose of embedding a jpeg when using the RAW mode?

Thanks,
Gary

Best of both worlds!

I'm a recent 10D owner too. Fabulous camera. You'll know that RAW has no processing and JPEG is a processed image. When you get your RAW image in your PC you will have to do something to it to make it viewable (or presentable.) The JPEG will look pretty straight away! If you have an embedded JPEG, I suppose you will either keep the JPEG or if you're not happy and want to tweak, you can ditch it and start again with the RAW.

I am just trying to get to grips with RAW and RAW conversion. I'm used to shooting JPEG which I have to say, are really good out of my 10D. When I get to understanding RAW etc. I'm gonna move on to embedded JPEGs and see if I can't get my head around that.

I'll be interested to see how this post develops. The JPEG/RAW debat will run for a while yet I guess!

The embedded jpg, first showed up in the EOS 1D and was for journalist, so that they could send an image dirctly home to the paper. In 10D/D60 it is primarily used for previewing the picture at the LCD-screen. But ofcourse you can extract it, but why bother since you have the "negative" (RAW). So without the embedded jpg the camera would have to "develope" the RAW-file before you could see it on the LCD.. simple as that.

Got my 10D last night (psyched!) so this is all new to me. I am a long time Digital photograph lover though, (Olympus C2100 Ultra Zoom most recently) and have now graduated to the "Real Thing" with the 10D.

One reason I can think for the embedded jpegs is if you are like me,. and have VERY LITTLE experience with Film Photography,. or have made the switch to Digital to the same extreme as a digital only user,..

... then you have absolutely no inhibitions of shoting the same subject 2 dozen times at different exposures, ISOs, angles etc. Film is Free!!!!!

That said,. you may not want to keep your hard drive stuffed with thousands of 8 Megabyte RAW images.

Look at the Jpegs,. and dump the bad pics. Then use the RAW image for the "Keepers" to get a better print/file to tweek. And yet save more of the Jpegs as a log of how you got to the "keeper" with experimentation.


As a complete newbie though,. I will admit I haven't even shot any RAW images yet,.... YET. But this is one reason I can imagine the embedded jpeg may be usefull
