.cr2,canon

I have pictures that I had taken with my Canon T3i Rebel, they have a .CR2 file extension. I am using Picasa as a photo viewer. When I choose to view them as extra large icons the pictures do not show up rather an icon with 2 green trees and a dessert background and blue show on the icon and I would have to click on it to see what the picture is. It does not do that with JPG file extensions . any solution to show the pictures .

Hi
This .CR2 file  is a raw image
Right click the file and use the "open with" whatever program came "native" with whatever version of windows you're using should be listed in the types of programs suitable
There is a plugin availabe

A CR2 is a raw image file format that can be produced by the Canon EOS Rebel T3i. Many software packages can open it. An excellent (free!) one is IrfanView, imaging software that I've been using for many years:
http://www.irfanview.com/

I recommend the Brothersoft link to download IrfanView:
http://www.brothersoft.com/download-irfanview-6224.html

This will download a single install file called <iview437_setup.exe> with no adware and no junk!

When you run IrfanView, you may either do a File>Open of the CR2 file (but make sure "All files" is in the file type drop-down) or simply drag-and-drop the CR2 file into the IrfanView window. Here's a screen shot of a Canon EOS Rebel T3i CR2 file in IrfanView:

Thank you Joe, I will try your Infranview. This question though is for Merete, I clicked on the link and I am not sure what I needed to do there. Am I suppose to download something? If so what is needed. I clicked on the open with the only thing that showed up was Picasa photo viewer, there was no other choices for me to select from. Please clarify to me .

You're welcome. IrfanView is a superb piece of software...I think you'll like it. When I first had to open a CR2 file, a friend recommended Photoshop, which is very expensive. I was happy to discover that the free IrfanView opened it fine...and it even let me convert the CR2 to JPG with varying degrees of quality, so I was able to reduce the size of the file. Of course, there's a balance between size and quality, so I played with the JPG quality slider until I was happy with the result. Here's a screenshot of the slider (done in IrfanView, btw), that shows it set at quality 80:

Joe Winograd, Fellow&MVEDeveloperCommented:
Our messages just crossed. Sorry about that...my fault. To open some files, such as CR2 and PDF, IrfanView needs PlugIns, which you may download here:
http://www.brothersoft.com/download-irfanview-all-plugins-164981.html

This will download a single install file called <irfanview_plugins_437_setup.exe> with no adware and no junk! Since you already installed IrfanView, just install the PlugIns. Then you'll be able to open CR2 files (and PDF, too). Regards, Joe

hmm maybe too many experts is confusing you.
I'll update this and then spare you until you decide if you want to use IfranView or simply install the codec so you can use windows photo viewers and adding support for Picasa.
Once you install the codec then rightclick your image and open with the supporting programs such as Picasa- Ifran view - even FastStone from the list it should now function correctly.

I dont use either Picasa or Ifranview and prefer to use my Nero photosnap and windows inbuilt Microsoft Office Picture Manager with the codec installed.

The displaying of thumbnails is a completely different issue. If you want to open a CR2 file in IrfanView, there are five methods:
(1) File>Open in IrfanView.
(2) Drag-and-drop into IrfanView.
(3) Right-click on the file in Windows Explorer (or whatever file manager you use), select Open With, and pick IrfanView.
(4) Right-click on the file in Windows Explorer (or whatever file manager you use), select Choose Default Program, and pick IrfanView (if IrfanView is not one of the choices, click the Browse button and navigate to c:\Program Files\IrfanView\i_view32.exe or c:\Program Files (x86)\IrfanView\i_view32.exe, depending on whether you're on 32-bit or 64-bit W7).
(5) After doing (4) and making IrfanView the default program for CR2 files, you may now simply double-click on a CR2 file in Windows Explorer (or whatever file manager you use).

Hi Joe. Where do you reside which country?

With the codec installed basemkhawaja64 can also view these from explorer
when the image is on the left by enabling the Preview pane as he holds his mouse over the image it is displayed in the side panel.
Pulling the separator line in a bit more will increase the size
With a folder full this is kind of handy
at the top of explorer> organise then layout

Paul,
I had him install all of the PlugIns. And if I'm reading the situation right, he can open a CR2 in IrfanView now, but doesn't like the drag-and-drop method. There's also the issue of CR2 thumbnails not being rendered in Windows Explorer, but that's a completely different beast. Regards, Joe

@Joe: reading the question, it seems he can open the files just fine in Picasa, but wanted to be able to preview the images in image explorer.
 
I know you use only "Detail view", but as I was saying in another thread, most people actually use icon view (S/L/XL).

So in this case, you recommending IrfanView (which is great) will not help the OP reach his goal: to fast preview the images within windows explorer.
Merete's suggestions (especially the FastPictureViewer Codec) will get him where he wants.

Hi Dan,
You may be right — I'm not sure. I don't use Picasa, so it's not clear to me what he means by "view them as extra large icons". I assume he's talking about viewing them in Picasa, not the "Extra Large Icons" view of Windows Explorer. I think it's likely that he really means "thumbnails" when he uses the term "extra large icons". That said, his comment, "I would have to click on it to see what the picture is", would lead me to believe that you are right, i.e., he can view them in Picasa.

Hi nobus,
Yes, JPG is an option on the T3i. Here are the possible JPG resolution settings on the T3i:

Paul SauvéRetiredCommented:
I managed to fix the problem of viewing thumbnails by opening the CR2 image with Windows Photo Gallery and downloading the correct codec. Once it is installed, the thumbnail images will show up in Windows Explorer.

Just a thought on .jpg vs. RAW formats: as most of us know, if you modify a .jpg image, always save the original and modify a copy, since every subsequent modification will lead to some deterioration of the image. The advantage of RAW is, although it takes up much more space, it is like a 'negative' of the original image.

Furthermore I will look into these setting on my camera to change to .JPG but for the pictures that I already had taken as raw what can I do to convert them JPG. Will I loose  quality in the mages that I will take with JPEG  next time I take pictures.

> for the pictures that I already had taken as raw what can I do to convert them JPG

As I mentioned in this previous post (http:#a39896579), IrfanView can convert to JPG. Just open the CR2 file in IrfanView and then do a File>Save As to JPG. As I showed earlier, the quality slider goes from 1 to 100. At a quality of 100, the JPG file will be large, but will be close in quality to the CR2.

> Will I lose quality in the images that I will take with JPEG next time I take pictures.

If you set the JPG quality on the camera to Large, as I showed in this previous post (http:#a39897387), the pixel count will be 5184x3456, which is the maximum of the camera (18 megapixels) and the same as RAW. The JPG quality at that setting will be comparable to the RAW quality.

The confusion is whether you were talking about being able to view thumbnails of the CR2 images (presumably in a gallery or strip of thumbnails) or view the actual CR2 images. Regards, Joe

basemkhawaja64 if you like to try it I provided 2 links to fastone http:#a39896627
which can also convert your raw CR2
http://www.faststone.org/FSViewerDetail.htm

With regards to loss of quality not really if you keep the aspect ratio.
The reason the raw is so big is because of the data it contains
If you don't want to do any post processing, then you simply shoot in JPEG.
Raw cannot be edited
Taking a picture in Raw is only the first step in producing a quality image ready for printing, I simply use my other tools to enhance the photos.
Paint dot net with it's huge array of plugins is priceless
An example here on EE recently we were playing around with enhancing a photo to an oil painting. We illistrated Paint dot net and I posted the links.

Every comment sends an email.
do you know you can edit your last comment if no one has responded that edit is available.
