File size/RAW?

[T.S.]

I'm new to digital SLR. I'm shooting in RAW with the 300D, 28-135mm IS lens. After I shoot I download into iPhoto where I read all my shots are coming in at 2.1MB, a few at 2.8MB but nothing bigger.

I'm sure I'm overlooking something but I was thinking my files would be coming in at 6 or 7MB as stated in the manual. What am I overlooking?

Are you sure that the camera is set on RAW? Sometimes I change the settings from large jpeg to RAW and forget to push the enable button and it stays at the former setting.

The only other thing that I could think that would make the files this small, is the picture itself. If the overall image has a lot of black in it, then it will make a smaller file, although I wouldn't have guessed this much smaller.

Also, if you shoot in one of the 'green box modes', the camera automatically switches to JPG.

You can use RAW only in M, P, A, T mode.

Best regards,

Today I was shooting in P and if I turn on the information for the pictures they all saw RAW.

I don't think you are going to get RAW files that small.

What got stored to the CF card? RAW or JPEG?

On my D60, the RAW files (are a little different) are about 6-9MB each.

Raw files are losslessly compressed and the compression will vary with the subject. If you are shooting pictures of plain painted walls, you might get quite small files, but 2-3 meg seems suspiciously low. Have you checked the file extensions once they are loaded to your PC?

Thanks everyone. I spent some time looking around iPhoto and from what I can tell iPhoto turns every photo into a JPG file javascript:emoticon(':cry:'). I'm going to spend some time seeing if I can find a program that will allow me to download raw into iPhoto.

In the meantime can anyone share some ideas of programs that will allow me to download in RAW? (I'm a MAC user)

How are you getting iPhoto to copy your RAW files? I have to convert them to JPEG with photo shop before i get iPhoto to accept them.

Or, are you only opening the embedded JPEG file?

The embedded JPEG can only be opened with dedicated software. Not sure how this guy is getting RAW into iPhoto! I am pretty sure he is shooting in jpeg

Just a note.. There's a very simple way to tell what kind of file you're looking at.

If the files are RAW, then the file extension will be .crw

If they're JPEG then the extension will be .jpg

Also.. If they are RAW there will also be a corresponding .thm file generated as well. In JPEG mode the camera doesn't create .thm files.

I'm not familiar with Iphoto, but if you want to read RAW files, you MUST have a program designed to decode Canon RAW. RAW isn't an image format. It's a proprietary method of storing data from the camera sensor and it requires special software specifically designed for the job.

It could be your Iphoto program sees the embedded RAW stream within the RAW file and you're reading that. Some programs will scan a file and read
images from within, ignoring everything else.

PS.. You should have a RAW file editing program for your Mac on the disk that came with your 300D. It's called 'File Viewer Utility' for the PC and I imagine it is the same for the Mac.

If you install that, you shoud be able to read RAW files with no problem. If you want advanced RAW processing, consider getting a program such as Adobe Photoshop CS. It has support for Canon RAW.

If you have USB or Firewire on your Mac, you might want to pick up a CF card reader.. They're ***much** faster than downloading from the camera.

I don't think there's any question about it. Iphoto is a Mac program, right? I don't know if they even use suffixes (sp?).

[Jonny]

Yes iPhoto is a Mac app, in fact it is the best photo organising app out there! But it does not read RAW and it does not read Embedded Jpegs. I know this because i use it and it annoys me.

[Keyser Soze]

I'd recomend you obtain a copy of Adobe Photoshop CS

I use iphoto to view my images with ease also and use CS to convert the RAW data and then import the resulting files into iphoto...

the file sizes generally are about 25~27Mb though so I'd assume that the data your seeing in the program at the moment is a unconverted RAW file......

...and thus.. it is far from the best photo prganizing app out there for many of us who shoot RAW....

I think you need to look at the files while they are still on the CF card.. where you will most likely see that the file extension is .jpg :wink:

2.# MB is exactly the size of a large fine jpeg from your camera.

I think you have all got me wrong here! I know whats what!
I was simply asking the original poster how he got iPhoto to read RAW files as, to my knowledge, cannot be done!

[T.S.]

Original poster here: You're right using the MAC OS X software "Image Capture" no raw photos can be imported into iPhoto. I love iPhoto and hope Apple with look to the future of digital photography and make some changes. From now on I will start using the Canon software and then use Photoshop CS.

Thanks for everyone's help!
