Raw & Jpeg?

Recommended Posts

Need more details of programmes etc to give a detailed answer but many photo programmes will only display the embedded jpeg, that is why it is there. The RAW details will not be accessible until it is converted to jpeg, or preferably TIFF.

 

Give full details of photo programme and RAW conversion software and then, if you still need it, someone will be able to assist with more help.

 

Alternatively, you have set the camera incorrectly, but I suggest that a conversion problem is more likely.

I use ACDsee 7.0 and Photo shop CS2, previously, when using MK2N the RAW file was not viewable by ACDsee, only by PS... now RAW file taken with 40D behaves as a Jpeg... wierd.

Camera was set OK, when pix r viewed in the camera they r displayed as:

RAW + L

ANy comments?

Sure, P does RAW & Jpeg..

 

Yeah, I hate using Canon software... never liked that.

What really puzzles me, that ACDsee shows RAW files as Jpeg, I can view them and couldnt view RAW with 10D... also the same of both RAW and Jpeg is the same and according to manula, On RAW + L jpeg, the size of RAW should be 12.4 and 3.5 megabytes.

 

If U have a look at the print screen, both are around 1.5 MB

I don't use the Canon software either. It seems like before I got CS3, if I opened one of the Canon programs, that I

could then open a RAW image in Elements. I think I remember the files showing info like your screen shot, till I

opened the Canon programs... but, I am not sure, it has been a long time.

 

btw...LightRoom is an awesome program, just updated to Lr2, it is even better than the original. I did have to update

to camera raw 4.6 to use Lr2 with CS3. There may be an update on the Adobe site for for CS2 camera raw.

I my have got hold of the wrong end of the stick here, but RAW photos automatically embed an identical Jpeg image into the photo (2 images - one RAW and one Jpeg in the same file). This Jpeg is adjustable for size with the camera settings. I use RAW & small Jpeg.

 

Some programmes, like I think ACDSee, cannot register the RAW image so they can only show the embedded Jpeg. That is why the Jpeg image is there. It is the same with many photo editing programmes. Most of the better editing software will allow you to open a single RAW file directly but you may have to use a special menu to open and convert the files to Jpeg or Tiff before editing.

 

The best method, I find, is to convert the RAW camera file to a usable format like Jpeg or preferably 16 bit Tiff using a specialist converting programme before editing the files. You can retain the embedded Jpeg as an extra image or delete it. Personally I just use this Jpeg as a viewing image and delete it during conversion.

 

If you had a conversion programme like Digital Photo Pro with your camera use this to convert the RAW files to a useable format before editing. DPP is a very basic bit of software so don't try to edit with this, just use it to convert. You can select all your images and do a Batch Process. Save them in a suitable folder for later use with Photoshop.

 

There is better software than DPP available, but if you have it use it. I found the instructions to be a bit vague but it suffices for me.

 

All should be explained in detail under the Image Settings chapter of the 40D manual. It is pages 55-58 in my book; but my UK book may number differently.

To the OP, make sure your viewing software is compatible with the Canon RAW files from your 40D. If you had your

camera set to record both RAW and JPEG you should have two files for each image. It may be that both files are on

your computer, but your software is unable to display the RAW file.

 

"The RAW details will not be accessible until it is converted to jpeg, or preferably TIFF." Not sure what is meant by this

statement, but it is not necessary to convert raw to JPEG or TIFF before viewing. I shoot raw only on my 5D and

Lightroom displays the raw file without converting.

 

"I my have got hold of the wrong end of the stick here, but RAW photos automatically embed an identical Jpeg image

into the photo (2 images - one RAW and one Jpeg in the same file)." -- true. When shooting in raw only mode, it is the

embedded JPEG that you are viewing on the cameras LCD monitor.

 

"This Jpeg is adjustable for size with the camera settings. I use RAW & small Jpeg." -- not true AFAIK. The embedded

JPEG is not variable. The RAW + (S,M,L) jpeg does not refer to the embedded jpeg, but rather the JPEG file that is

recorded separate from RAW file.

I have not read over all the posts here as I am very tired, but I had this sort of thing happen with a rebel xt set to jpeg+raw, I transferred the files to my pc and it made 2 copys of each photo both jpegs no raws. I forget exactly how i got the raw files off but it had to do with the method in which I was uploading the photos... being either through a card reader on my pc or the usb connection to the camera itself and then using microsoft scanner and camera wizzard (which is what i normaly use and i think is what gave me the problem as it saw only the Jpegs and wouldnt let me use the advanced options as it does when i take only raw) anywho, try taking them directly off the card via a card reader.

OK Douglas, I was trying to put things as simply as possible but we are talking about ACDSee here not Lightroom and as far as I am aware, ACDSee will not display RAW files. My earlier version 5 certainly will not show them.

 

Some programmes will show just the Jpeg, some both RAW and Jpeg while others show Jpeg and a blank.

 

Just trying to be helpful and work out where MM is going wrong here. And, I'm afraid RAW shooting tends to be a complicated business nowadays. RAW or RAW and 6 choices of Jpeg. Then there is sRAW and another 6 Jpeg options.

 

While the Canon manual mentions a little bit about RAW it doesn't really go into sufficient detail.

 

I'm still uncertain about what MM is doing wrong here but suspect he is trying to view his RAW files with the 'wrong' software so all will be fine if he uses a different programme like Canon's Digital Photo Pro.

 

I have seen some articles which went into a lot more details about RAW and gave easy to understand explainations in laymans terms but I can't remember where I saw it. Can anybody recommend anything here?

M M, now that I have had sufficient coffee.:) Try what Michael Bordak suggested and view the card via a card reader. You

should see both a .crw and .jpg file for each image. Copy both files to your pc. Make sure they both have copied and

retained their original file extensions. (,crw and .jpg.) If so, then, as Geoff has suggested, it becomes a question of whether

or not your software can view the raw file. Make sure it is compatible. Good luck!

Had to download a new plug in from Adobe to get CS to read M8 raw files, or convert them via software included with

M8, which was Capture One, and not fast, nor easy. As I recall, Adobe has instructions for installing it, if needed,

and there are several versions of Raw plug in, I just took the most recent. Probably not a bad idea to get the latest

and greatest free downloads until PS upgrade time arrives.

 

I understand if you are shooting raw, and converting to tiff, you want to make sure it is 16 bit, I think Leica files may

come up looking 8 bit, but are supposed to be 16 bit. I also understand, as probably everyone else here does, that

there is much more advantage to 16 bit.

 

Hopefully some of this applies to the OP, Leica uses DNG raw, but the plug in download from Adobe lists a lot of

cameras. Am hardly a digital expert, FWIW.

 

Regards, John
