Shoot in Raw and Jpg

[chartbin]

A newbie question,
why would one shoot in the Raw + jpg mode?
Doesn't the jpg just use up more space?
Can't you convert in PS the RAW to jpg later on?

Just pondering?
Please help.

Cameras are different.

Besides the JPEG modes, some Canons have RAW only and no RAW+JPEG. Some have RAW+JPEG only, and no RAW.

A RAW+JPEG would allow you to get a viewable/usable JPEG out very fast and still have the RAW hidden back there as a "digital negative".

A RAW only has the advantage of taking less memory space, but it takes a little longer to produce a JPEG or TIF from it.

What is more important to you, time or memory?

I am preparing myself for the arrival of my 20D which allows for raw+jpg.
Seems that just with ONLY raw at 8 MP, I can get about 120 pics in a 1G CF card. With "+jpg", even less.

Should one pick raw+small jpg as a rule of thumb, just so one can view the shot "on the spot" and process the "final" image at home onyour PC?

What's one to do? :?

How did you get from 8 megapixels to 120 pics on one card?

1000/8 = 125

I don't like to shoot in RAW when it's cold outside !

Get premature shutter release ;-)


Kidding guys. take care, Rod

From the 20D user manual.

Although size may vary depending on the actual image, Canon mentioned that the raw alone is about 8.7 MB per shot or 27 shot per 256MB CF card, therefore, 27x4 = 108 shots per 1G card
My initial arithmetic is off or a bit too optimistic!

Shoot in RAW and buy/use macro/zoom lenses.
Now I see why Canon marketing group is pushing the raw format
:D :D :D :D :D :D :D :D

why would one shoot in the Raw + jpg mode?

A rare need, but no less valid; the raw file will give the best results once properly "worked on", the JPEG can be printed immediately via a "direct print" printer - even away from mains power. This was in fact one of the reasons that I pre-ordered my 20D. :)

Yes, I thought as much. That 120 number seemed optimistic.

I think you will find that it is most convenient to shoot in both RAW and JPEG. When I am out with family my wife likes to keep all the pictures but I certainly do not have the time to process all of the shots in Photoshop. I use Breezebrowser to seperate all the pictures into 2 files ie the Raw and Jpeg and then I reveiw all the pictures and only spend a lot of time processing the real "keepers". I can keep all of the shots and also the TIFF files from the photoshop processed files. The TIFF files also take up a lot of space and especially when saved to a CD file take a lot longer to pull up at a later date.

[chartbin]

Is there a way to "program" the 20D or similar to
switch between jpegs (family pics) and raw+ jpg (artsy stuff) EASILY?

[Photorob]

Takes two seconds on the Mark II. Push a button on back and turn dial. You do not have to access the drop down menu.

Here is an awesome advantage of using JPEG AND RAW:

You can shoot in B&W (or sepia, etc.) and have the color RAW (uneffected) for later use.

That is a huge benefit in my book.

How do you shoot in B&W?

There is no B&W option for JPEG or RAW.

If you want B&W, then just process the RAW to TIF or JPEG and convert to B&W. Then, if you want, process the same RAW to TIF or JPEG and not convert.

On the 20D, there ~is~ any option for B&W.

If you don't have to give up the color RAW, why ~not~ experiment with in camera effects?

Really? That's a complete surprise. :shock: (Tom goes back to the Canon website to read further......)

[robertwgross]

20D has a processing parameter for B&W.

What does that mean? You can't capture B&W.

You're still shooting a RAW file and saving a RAW file. But during conversion in the computer, it can get processed as B&W (?)

This is from the Canon website on the 20D:

The EOS 20D also features a built-in monochrome mode, a first in Canon Digital SLRs, which uses digital processing to re-create the effects of a number of different black and white filters and toning effects. These features help to take the guesswork out of black-and-white photography, reducing the need for post processing by delivering the desired detail and contrast of a black and white image from the start.

So, what does that mean?

Is it just a flag on the RAW file so that the RAW converter in the computer does something special?
--or--
Is the image processor in the camera doing something nifty to strip out all of the color information before saving the RAW file?

I'd kind of hate to save a RAW file with no color information in it at all. I'd kind of like to have the color information and then do the B&W conversion in the computer, and still save all of the color information there, just in case it is good in color.

I dunno.

I'll let you know when (and if) I ever find out. :?

The camera's firmware desaturates the color image much the same as photoshop does.. There are built in algrothms that allow you to apply different "filters". Since the sensor is a color sensor, the RAW output is the same no matter what mode you're in.

The thing is ... All this B&W stuff can be easily done in photoshop after the fact with the appropriate actions. The only thing the B&W option in the camera does is save you from doing it later.

It's a gimmick :)

[robertwgross]

I feel so relieved.

I notice where the Canon utilities treat the 20D RAW image somewhat differently from the RAW images of 10D and the others.
