What does CR2 stand for

Graham Thirkill Loc: Idylic North Yorkshire, England UK.

Please, can anyone answer my question? I have just taken a series of photos, I put the flash card in the card reader and put it in my lap-top. Iv'e opened it to see the list of images and every one of them is duplicated, for example: The list reads:
IMG_2271.CR2 DATE & TIME 24.7 MB
IMG_2271.JPG DATE & TIME 6.2 MB
IMG_2272.CR2 DATE & TIME 23.6MB
IMG_2272.JPG DATE & TIME 5.5 MB
IMG_2273.CR2 DATE & TIME 26.3MB
IMG_2273.JPG DATE & TIME 6.5MB
The CR2 files (whatever they are) are more than three times greater than the JPG files. There are about sixty of them all duplicated as above. ????????????????????? thanks Graham

It captures images in JPG as well as in raw format. In your case you are using a cannon camera so raw file extension is cra2

Graham, your camera is obviously set to capture both JPEG and RAW format. You can change this in the settings. RAW format requires a conversion process using the Digital Photo Professional software or Lightroom or Photoshop or Photoshop Elements etc.

The RAW format stores a lot more detail and offers you a lot more processing flexibility.

RAW is well worth the research and extra bit of work involved.

Krunal, I am very grateful to you for taking the time to help
me. I must have somehow altered the settings and caused
my camera to record both JPG's and CR2's.
Very much obliged,
Graham

Andrew, thanks for the help referring to the CR2's. Should I keep the setting on saving both formats. I must have changed it from saving JPG's only, by mistake.
Or change the setting to CR2's when shooting something special. As you can see, this is all new stuff I haven't used before and am very grateful for your help.
Cheers,
Graham

Graham, really a personal choice depending on what you want to do with your photos. Personally I only shoot RAW because I prefer to process each one to create the JPEGs myself. I use Photoshop Elements and it is really quite easy to do and I enjoy that part of it. If you want "instant access" to JPEGs when you download then keep JPEG on too. I would however keep RAW on at all times for the occassional shot where you don't quite get the shot right, because RAW often lets you rescue a shot that you wouldn't be able to do with the JPEG.

Andrew
Thanks again. I use 16gb cards so I will give it a spell saving the two formats.
Thanks again,
Graham
