LR3 export original question

Hi all,

I shoot .CR2 RAW files and process in LR3. Ideally I need to adjust the color temperature of my RAW's and export them to a temporary folder on my desktop as RAW's so I can make a CD of those with .jpg's.

From what I read in the Export box I can only export files as JPEG, PSD, TIFF, DNG, or Original. When I choose the Original setting it exports the original RAW without the color temperature changes that I made.

Is there a way to export RAW's with the color temp. changes that I made?

Thanks,

LR does not write the changes into the raw files. It saves all these parameters to a sidecar .xmp file.
Does it create the .xmp file in the same folder where you export the raws?

The problem is that xmp files are not read & interpreted by most picture viewers since they seem to be Adobe specific.

Why are you not exporting directly JPGs from LR since you need JPGs for the CD? Are you using a different raw converter to turn them into JPG for the CD?

Lightroom doesn't write .xmp files by default you have to change the settings:

Choose Edit > Catalog Settings (Windows) or Lightroom > Catalog Settings (Mac OS).
Click the Metadata tab, and then do either of the following:

To write adjustments and settings metadata to XMP, select Automatically Write Changes Into XMP.

To write adjustments and settings metadata only to the catalog, deselect Automatically Write Changes Into XMP.

If you don’t write adjustments and settings metadata to XMP automatically, you can select a file and choose Metadata > Save Metadata To File.

Not just LR, no Raw converter in the world will change Raw files - they are always treated as "Read Only". Moreover, you can't change the color of a Raw because Raws have no color. The color is created during the process of generating a jpg or tiff from the Raw data. First the basic color is interpolated from the Raw data according to the camera sensor profile and then the WB is done. The editing done to the image can only be seen outside the converter in a rendered jpg, tiff or psd.

Actually there is one way to export your RAW files with changes. Select the RAW files you want and go to File > Export as Catalog, then burn that mini catalog to the disk as well. However those changes would only be readable by someone else with LR3 who could open that catalog. RAW processing packages are not compatible. CPP, Paintshop Pro, DxO Optics Pro etc can't read Lightroom adjustments.

Can I ask why you want to put RAW files on a disk? If you are doing this to send to someone else then you would almost certainly be better off saving the images as uncompressed TIFFs. There are only two reasons why someone else would want RAW files...
1. They intend to do their own editing, in which case they are capable of doing the temp alteration themselves.
2. Someone mistakenly told them "you should have the RAW shots" - which they will almost certainly be unable to view or edit - when what was really meant was "get high res versions" (TIFFs).

Thank you for your answers. The reason I want to put the RAW files on a CD is that at my church I take baptism photos for the parents around once a month. I like to put the RAW files and the converted .jpg's on a CD (along with a 14 x 11 picture) as a gift to the parents. I figure if the parents ever want to have someone else print them up that person would rather have the RAW file and not a .jpg file to start with.

Up until last year I used DPP. With that I could correct the color temperature, convert to .jpg, and then save it in the same folder so that when I made the CD the color temps. were corrected. I guess from now on I'll have to include a note with the CD letting them know that the strong yellow cast doesn't affect the quality of the picture and to ignore it.

I thought about converting to TIFF's but the size is too big for all of the pictures on the CD.

Thanks,

I figured it was something like that. You can call off the search because you are wasting your time. RAW files are specialised photography files. The Windows OS doesn't even recognise them by default (at least not newer ones - you need to find and install a special codec) and most standard art packages that these parents would have access to will be unable to process RAWs. Unless they were pretty serious photographers, who have specially acquired a RAW processing package, they won't even be able to view them. What is more none of the places they would take the file to get it printed will/can accept RAW files.

By far the best format to allow these folks to print would be a full size jpeg or a TIFF.

Yes but they would only be able to see that correction if viewing the image in DPP (and in a version new enough to support your camera). Only DPP is able to emebed additional RAW processing paramaters within the actual CR2 file. Also all RAW processors from different companies are incompatible with each other. There is a small exception with Adobe as they have one RAW processing engine in three differing variations. PSCS and Lightroom have the same RAW processing tools with different interfaces, in PSCS this is the ACR plug in. In Photoshop Elements you also have ACR as a plug in, but in this case you get a version with most of the advanced tools removed. You also get differences in the tools with each version, so you would need to be comparing the equivalent version of each.

Honnestly if you are giving someone a disk of images of an event I would put two sets of images on. One set of JPEGs at full camera resolution, saved at around 80% quality (or level 10 in photoshop) for them to get printed. The other set of JPEGs I would resize to 1024 pixels long on the long edge, at around 60% quality for use on Facebook etc or to email. Also I would provide a text file with a printing release, so they do not get any problems when taking the disk in for prints.

If you are doing this for parents/clients, to me it makes no sense to export the Raws. They probably wouldn't have the slightest idea as to what to do with them.

Do the Raw processing, then export high-quality jpegs, and they should be happy as clams for high-quality prints. You can even view high-quality jpegs on most photo viewers and the viewers will "resize" them to a "normal" viewing size.

Why are you not exporting DNGs?
This format has all settings embedded and also has an embedded jpg preview generated with those settings. And you can also embed the original CR2 in the DNG if you really think it will be more useful that the simple DNG file...

I would suggest giving just the post processed jpgs. Most folks don't know what a raw file is, nor what to with it (and they may not even be able to view it).

If you color corrected, then editing the exported jpg should be fine, in my experience. And if you did your post well, there's no need for editing :)

DNGs would be just as useless as RAW files. The OP wants to share images with parents (most of whom almost certainly aren't photographers) so they can get them printed. They won't be able to use DNG or RAW files and it is very likely that the places they take them for printing wont be able to either. Most photo printing places will want a high res JPEG or TIFF file.

Even tiffs can be very "iffy"...

To the OP the only "safe" way of passing photos is to convert them to jpegs using the srgb color space. If you are not familiar with these things, please, stop, read up, and ask!!
