Is it possible to re-size RAW files??
 

As a bird watcher 1st and photographer 2nd I tend to post on Bird Forum and there are some very knowlegable & helpful people there.
However this question is specifically camera/computer based.

For the 1st time I used RAW and want to e-mail a RAW file to someone so I can work on it "with them" in order to learn a few basics.
The file is 15.MB so I would like to re-sze as you can with jpeg. so far it looks as though this cannot be done. I have googled the question and again it looks negative.
I have PS3.
Does anyone know if it is possible for this technophobe to do?:confused:

I doubt very much if you can do this David, it goes against the whole idea of what a raw file is.

Rather than emailing it, you could use your internet service provider's web space (the vast majority of ISP accounts come with some web space for the user to utilise), and upload the raw file to a folder. You could then email your friend a link to the file where they could then download it from.

Contact your ISP, or take a good look around their home page, to find out about user web space, then get hold of a program such as the filezilla client
http://filezilla-project.org/
to upload your raw file.

Yes-I thought it seemed to go against the idea......maybe I should have used a smaller RAW setting in-camera?
Your advise would be good to anyone with 1/2 a brain but from inside my head........:eek: Mind you I should (will) have a look and might surprise myself.
Thanks

Hi David,

Try You Post It = http://www.yousendit.com

It is a way of emailing large files and there is a free version.

I use it for people who don't have ftp.

The raw file is the raw file, there is no option to have a smaller setting for the raw, only smaller jpegs.

I know the Canon 40D does give the option of 2 settings. (RAW & sRAW)

I note that Photoshop ACR gives you the option to resize and save as a .dng which is an Adobe RAW format. Agreed this would suffer from re-sampling artifacts in the same way as re-sampling in Photoshop proper.

Hi David,

Another option is to 'wire' it to the other person. Slight technical hitch though...the person you're sending it to does need to have an FTP address ideally.
Many FTP programs are around on net searches for no or little money. I use coreFTP, but others work just as well.
Assuming the above is done, it's just a simple 'drap and drop' operation to use....and is very quick too.

...just another idea to throw into the pot.

good luck

Why not zip it, I've just compressed a 15mb NEF down to 9mb using WinRAR, there are other compression programs that could make it even smaller, such as 7zip. Whoever you send it to needs to have similar software installed on their computer in order to re-open it.

Hi

I'm a fan of YouSendIt - I often send 64 MB TIFF files to agencies this way.
The free version allows single file transfers rather than batches but it sounds like that will do the job.

You can always save it as a TIFF and send It and then get your friend to open it in bridge and then use the command to open in RAW as if the Image was taken In RAW then it will maintain the RAW data and also be a big enough file to work with.
Hope that was of help.

Just realized its an old post :). But I'm sure it'll come in handy for you or someone else.

not sure how this would help as surely a TIFF would be a much larger file than a RAW?

Sorry, my fault, I forgot to mention that It can be saved as a TIFF or JPEG and reduce the size and still maintain a good size and RAW data to work with. As you don't need a massive file for a tutorial.

Also If the full size does matter, then i believe Googlemail Is good at handling large files.

The TIFF file will be larger than the RAW I reckon (if uncompressed) so the OP will be back to square one.

Did you read the bit after that quote?
Then it can be saved as a JPEG and still retain the RAW data? That's why i gave the two options. The two options are for the fact that some people can send larger files than others
Try It out its a good thing to know.
Happy Christmas by the way.

This thread has completely lost me :confused::confused::confused: - the OP wanted to reduce the size of a RAW file because it was too large to email. He clearly wanted to send someone the RAW file (not a TIFF or jpeg). How the heck converting the RAW to a Tiff which will be a lot bigger file size can help I do not know. Then you suggest converting the TIFF to a jpeg :D I am sure the OP could have mailed a jpeg in the first place if he had wanted that.

Maybe I am missing something here but I am completely bewildered - time to kick this thread into touch I think.

Roy,
Read what it says properly. He wanted to send a RAW file so he/she could use the RAW settings in a tutorial.
What i have suggested is that if he is struggling to send a full size file then he can convert to JPEG and that can be opened in RAW via BRIDGE with the RAW settings in tact. Sending as a RAW or JPEG (as it was originally shot in RAW and retains the RAW data) is not a problem as it is just needed with the RAW data and can be opened In RAW. This technique is nothing what so ever to do with shooting in JPEG as a true jpeg will not have the RAW data to begin with.
I think you should read what i said and corrected properly, then once you understand as you say "your a bit lost", and have tried it then you might see what i am on about.
The TIFF as i said was for anyone who can send larger files, the JPEG is for the ones who cannot.
But remember the KEY POINT that a converted RAW file to a JPEG has nothing to do with shooting AS A JPEG.
HTH you.

P.S I'll do a tutorial if you like to help you out if you cannot grasp it, as soon as i get some time.

Cheers

On my version of CS4, when you open a jpeg in bridge you go straight into CS4 and not ACR. I have not got a clue what you are taking about when you say 'that can be opened in RAW via BRIDGE' Nor am I particularly interested.
When I made my post I was responding to a post that you made which suggesting that if the RAW file was too big then he could convert to a TIFF which made no sense whatsoever to me as the TIFF file would have been bigger.


Please forget the tutorial onj my account as I am not interested.

Firstly you are interest or you would not bother replying to the post in the first place.
Secondly when you made the reply you jumped the gun as i corrected myself and you did not read it as i have already stated.
You are correct, you obviously took note about an original JPEG that it does not retain raw data and goes straight to photoshop.
What you keep MISSING is that you can save a RAW file as a JPEG and it will retain the RAW data as it was originally shot in RAW.
A quick tutorial for you.
This is how it works-
1. Open the RAW file in Photoshop.
2. Save as JPEG or TIFF (i won't get into the tiff side as i don't want to loose you)so we will stick with the JPEG
3. Now you send the JPEG (Remember the converted RAW File) to friend.
4. The friend saves to where ever they prefer.
5. The friend opens in Bridge.
6. The friend now opens in RAW by one of the two way command/control "R" (the short cut. Command for Mac control for P.C users) or file, camera raw.
7. The friend now has the JPEG file open in RAW with the RAW data intact.

Try It, Its something new for you and If your not Interested then that's no problem but I'm sure there are people out there willing to learn new techniques just like myself.

If we go back to the origins of the post (including what was posted on birdforum) it was the friend who wanted the raw file because they were going to give the tutorial to the sender.

If I understand you correctly you are saying a tiff or jpg will contain the original data of the camera RAW file ? If that is what you are saying then I would very interested in knowing how on earth it is going to achieve that.

Hi Rob,
Thats what I am saying.
Do an experiment. Take a picture in camera as a jpeg then follow the tutorial above, the part where you open in raw from bridge. You will then see that there is no data or it won't open.
Then try it my way with the tutorial above and you will then see that you can open from bridge into camera raw and have full RAW data.
I have to do this technique a lot.
If you have ago let us know how you got on.
Happy christmas.

I don't have any call to use Bridge and I am sure that your method does work to edit a jpg in ACR and of course the controls will work in the same way.

What I do question is your logic that you have the original RAW data in the jpeg.

Camera RAW is normally 12 or 14 bit data dependant on model of camera. Jpeg is only 8 bit data RGB.

The 8bit data is derived from the 12/14 bit data after gamma curves have been applied based on brightness, contrast, saturation, colour balance and exposure settings.

In some cases the only difference between 100 ISO and 200 ISO is the gamma curve applied.

Readjusting these based on jpeg 8bit data is not better than adjusting in Photoshop other than the controls maybe more intuitive.

It will be interesting to see a correction for 2 stop under or over exposure using your method compared to processing the original RAW file.
Or even temperature correct for a camera set up for tungsten lighting but shot in daylight.

HI Rob,
If you want to send as the OP wants then you would want to use bridge (or any other method that you may find) as Its just for a tutorial purpose and no need for high quality.

Now you are going off track with the 8 bit and so on, I am not talking about the data in that way as that has not been mentioned, So lets not start getting to deep and loosing people even more :).
Working In RAW compared to JPEG Is the best way as like you said It retains more data and values. I am like you mentioned talking about the controls that will be in tact (maybe i should of made that more clear when i mentioned data instead of saying controls). as that Is what the tutorial is for and the quality will have to be scrutinized which I'm sure you will, If It was going to print and so on. but for a tutorial and for someone who can only send a small file Its the way to go, as the person doing the tutorial Is obviously showing them how to use the controls in RAW.
That's my only point, I have never said that It would be as good as a RAW file but If you compare the RAW to the JPEG then you will see for the purpose of a tutorial It not a problem.

There will always be a down side in working in JPEG compared to RAW.

Quite agree with this. Rob knows his stuff on this subject, REALLY knows his stuff. See this thread:
http://www.worldphotographyforum.com...ead.php?t=2523
for everything you ever wanted to know about conversion to jpeg. You cannot retain the full raw data in a jpeg.

Hi Yelvertoft, Don't take this the wrong way but did you read the the whole 3 pages? and more importantly did you read what i said after Rob's last reply. That i should of said controls instead of data to keep it simple and not get people confused. My fault.
Glad he does know his stuff (It'll be great to pick his brains now and then). He will then know that the controls are available in camera RAW AND WILL be good enough for the purpose of the tutorial.
I have not mentioned anything to do with the RAW values or bit data.
This is what people are missing.
The whole point of what i am saying Is that THE CONTROLS ARE AVAILABLE IN CAMERA RAW WITH THE JPEG. and that can be sent to the person who wants to do the tutorial.
As I have already mentioned there Is nothing better than working with a raw file as a JPEG Is limited.
But AGAIN the purpose of my reply to this is that someone wants a tutorial doing on camera RAW and is not able to send the original file. So If the person converts it to a JPEG and sends it, the person doing the tutorial can OPEN IT IN CAMERA RAW VIA BRIDGE AND THEN DO THE TUTORIAL USING THE CAMERA RAW CONTROLS.

Because someone may know everything does not always make them right. We all learn something and unless he and yourself try it and see then there Is no point to the replies as we are going round in circles.

ps. IF you do want to try It to see that I am correct then before you do (and i am not trying to be clever) go to Bridge, open the camera RAW preferences and make sure that JPeg and TIFF handling is set to "Automatically open JPEG with settings" This Is probably were Roy C went wrong, but he did not want any helped.

I suggest you to ZIP the files..... than in case you are not able to send out due to ISP limits or Mailer limits... you can use servicess online that allow you to send out to them big files.... after that you must send to your friend a link of those services from where your friend can dowload the files.

Hi
am I missing something, I thought the problem was sending a RAW file as a (raw file) maybe I got it wrong I've been sending photos in raw format using like Derekb suggest yousendit with no problem for some time

Hugh I believe the issue is e-mailing 15Mb files, Some mail servers are not happy to receive them or it maybe the person receiving is still using a 56K dial modem.

Believe or not everybody is on broadband.

Hi rob I just wanted to stick my farthing's worth in
