Is Lightroom working on jpeg or raw image, if both are available?

Sorry all, I know this is out there somewhere, but my searching didn't come up with an answer.
If I shoot my original images with raw and jpeg simultaneously, and both image types are stored in the saved location, which of these is Lightroom using as it's starting point for editing? Another way to ask this question is, when I save my Lightroom changes, to which image is the parametric data applied? Is this a stupid question? I'm not sure why it matters, even to me, but I would like to know, although if I do an export of the modified image, I'd rather it make the 'changes' to the raw file, even if I'm exporting as jpeg. Or does it even matter? Am I just babbling like an idiot here? Am I totally messed up in my thinking? Please help, or tell me to just go away...

My "probing" question would be: why put both in the Library? If you work on just the RAW file, you'll save space, and never worry about which version of an image is current, etc. (Yes, I am aware that some just prefer to see how the camera converts the date to a JPEG)
Good luck!

Automatically export to JPEG from RAW images

RAW images are preferred form of shooting for many photographers. And, Lightroom is great at managing and developing these images. However, we increasingly use/view these images outside Lightroom and away from the PC where we do most of the development. For example, I use a DLNA server which shows off my entire image collection to big screen television (which can act as a DLNA client). The same DLNA server is used to send images to our smartphones (my wife loves to show all kid pictures anywhere she - without having to carry the pictures on the phone).
Most other applications that use these images, do not work on RAW images and JPEG images must be exported manually from Lightroom. This becomes increasingly difficult to manage and keep track of while developing RAW images. How many RAW images need to be exported? How many images did I touch since the last time I exported them?
Currently, I am using the following process to manage this:
1. I created a smartlist which contains images that are edited after "a particular date".
2. I select all images in this smartlist, and use Lightroom3's export function to export them all as JPEG, to the same folder as original.
3. Once the export is completed, I modify the smartlist to change the "particular date" to today's date.
I plan to repeat this procedure every so often (once a week or so).
It would be great if Lightroom had a feature such that it always keeps "JPEGs exported" for all RAW images (with the latest development settings of course). This could be a process that could occur in the background or at a user-specified time/event (e.g. when one closes Lightroom). User should be able to specify where the exported JPEG images should be put to and with what name (I prefer in the same folder as RAW but other users may have other preferences). User should be able to select if this is only done for RAW images or also for JPEG and other formats (in which case, should the exported image override the original or not). The exported images should be (optionally) automatically included in the Lightroom catalogue and stacked with the original RAW image.
Mainly, the entire process should be completely transparent to the user. A collection of JPEG images - corresponding to the latest development settings for the RAW images - should be always available.

I've heard many others raising the issue of an auto-jpeg feature - kinda like auto-write xmp, except auto-write jpeg.
I agree this would be nice, obviously some sort of "stability" check would be needed so it isnt constantly writing jpegs as you edit. Lightroom employs a form of this already for the xmp - meaning it doesn't update xmp every brush stroke, but accumulates several strokes before updating, so its more efficient...
If you could define multiple jpegs to keep - with the raws, or a separate tree - even better. That would obsolete all the tree output plugins and publishers.
The publishing feature was intended to fill this need (albeit manual only), but it suffers from the inability to publish to original directory, and/or an external tree.
I'd like to see a manual mode too, that accompanies a new "Done for now" function - so when you say "Done for now", it saves xmp, jpeg(s), snapshot, and optionally locks the file so unapproved changes can no longer happen to it. Then if you could define multiple "done for now" presets that include initiating publish service and exports, then the work-flow becomes: 1.import, 2.edit, 3.done for now - and thats it (maybe repeat 2 + 3 in the future). i.e. no more manually initiating the exports, publish services, snapshots, saving of xmp, ..., and whatever else you do when you're done.
In the mean time, I may make some of this part of an up-n-coming "Sidekick" app + plugin combo when I get to it.
Presently, I dont use publishing services, and I have ExportManager to consolidate exports (which includes TreeSync), so my workflow is: 1.import, 2.edit, 3.done for now (save xmp+snapshot, and lock via ChangeManager), 4. initiate consolidated exports...

When I use Preview,Photo Mechanic and Pages, all JPEG or RAW images appear corrupted. I thought my hard drive was failing and replaced it and migrated everything over but the problem still exists. Any idea what is going on?

I thought my hard drive was failing and replaced it and migrated everything over but the problem still exists.
It felt as if maybe a virus was at work but I ran Sophos and found nothing.
I store images on my Drobo Raid system but when I work from my Macbook Pro I have no issues, just on the tower.
Any idea what is going on?

First of all, why did you say yes to Nero Back up before researching what it does with files already on the HDD? When I install Nero, the Back Up is the first thing I disable, it is a nagging pain, there are much better backup programs available. There are several file recovery programs out there to recover deleted files, that is, if that is what happened. Also, if you haven't overwritten the files, so you should be able to find them.

Lightroom 4.3 corrupts my RAW images stored on local SSD harddisk

Using Lightroom 4.3 with Camera RAW 7.3 on latest MacBook Pro with 256 GB SSD harddisk, 8 GB internal memory bought 2 months ago. Hardware shows no other problems or malfunctioning, no issues with RAM or otherwise.
Started Lightroom 4.3 did an import from perfect images (viewed before using various other software packages) stored on the harddisk. Used option ADD to add to the catalog. Almost immediately certain images were showing missing areas or areas with pink/white stripes, etc.
I didn't even touch the images to view or edit them. The images were corrupted on disk as previewing them with other software packages showed.

If we're talking about the raw rendering, and not just the jpeg, then this means transfer hardware is OK.

That is not so true. Hard disk, ram, cpu, ..., - all play a continuing role.

No proprietary RAW format e.g. I use standard Canon 550D settings. Not sure how proprietary you call that and what I can do about that and why Lightroom would have a problem with it. If that would be an issue I would expect a lot more issues from other users.
A proprietary raw file is any raw file that is not DNG. The distinction is important because:
* Proprietary raws can not be corrupted by Lightroom (that statement has 99.999999999999% probability of being true, in the context discussed so far).
* DNGs on the other hand, are, in some circumstances, completely re-written, and can, therefore, be corrupted on Lr's watch (due to hardware failure). Granted, if such failure does occur, Lr is able to give a fairly clear & unambiguous message, since it keeps check codes for raw data integrity assurance. Note: such protection assumes the image was good when initially converted to DNG, and went bad after-ward - which is not necessarily the case: thus a good reason to visually inspect all images after conversion to DNG.

Software:
No other software
*iff* it is certain that raw image (raw-rendering, as distinguished from jpeg preview), was OK, before accessing via Lightroom, the other software is a non-factor.

Calibration display:
XRITE i1 display pro
I am a bit confused why a calibration file would get off-balance after some time? You need to recalibrate the display once in while, but that's because the display is changing.
I can understand Lightroom has problems with a corrupted profile, but how can it get corrupted as I would assume it is only read (not written) and why is Photoshop not having these issues?
My focus is now on recalibration of display to rule out that item
Not my area of expertise. However, in general, if you're having uncaught disk or hardware problems, or even software bugs, files can become corrupted - not just image files.
PS - Did the Mac/HW test include the drive where photos are stored?

Raw images from 1GX are rendering soft in Aperture - crystal clear on Lightroom

I have just upgraded to a Canon 1Gx MK II as my point & shoot. RAW images are rendering terribly soft in Aperture - crystal clear in Lightroom. Any ideas?

Have you in-camera settings applied, when you take your RAW photos? Aperture will ignore any of the in-camera settings when developing the RAW.
Have a look at Keith Barkley's User Tip. See this link:
The Big Three: Setting your camera for the best Aperture RAW results
Also, you may want to check the RAW Fine Tuning settings in the Adjustments panel. Perhaps these setting have been changed from the default values.

Why does my PS work better than my Lightroom 5 exporting jpegs from raw files?

So,
I'm editing some raw files with Lightroom 5
but when I export the jpg file, the result is terrible, it looks washed out, loses contrast, noise levels are higher than the edited file on suite
However, if I do the same thing using camera raw through PsCS6, the exported jpg is perfect. Any reason for that to happen?
've been reading a lot about color spaces, and I don't think is the case, since the same doesn't happen with photoshop.
Also, it might be worth mentioning I'm exporting B&W images
Thanks!

ok
just to illustrate the problem a little better, here's the actual difference
this is what I have in Lightroom after editing:
and here's what I get after exporting

Does Lightroom 4.2 support d3200 Raw images

I tried importing but all that showed up was the JPEG. Is there a plugin available?
Thanks in advance.

According to this, LR 4.2 should support it.
It may be an operating system issue if you are connecting directly to the camera via USB. Try to use a card reader instead.
P.S. There are no "raw-support-plugins" for LR (like for Photoshop). Raw support updates in LR are always done by a completely new LR update version which contains the newest build-in Camera Raw (which cannot be updated separately like in Photoshop).
Edit: Correction: Must read: no "raw-support-plugins" (not now ...)

Photoshop CS6 stops working when combining HDR RAW images

When I have made 5 HDR RAW pictures and want to combine them within CS6, the program Photoshop stops working. Why is this happening? What am I doing wrong? I juist follow the instructions of the book.

Dear Chris,
I have been waiting for about 45 minutes after starting the process, and then I stopped manualy the process because nothing happend anymore.
I use a MacBook Air.

Lightroom not seeing RAW images from Canon 20D

I am running Lightroom and if I take RAW images on the Canon 20D and I click Import, select the 20D as the source, it says "No images to import" now if I open the EOS transfer utility and download it there, save it as a CR2 and then Open it in Lightroom it all works fine. Am I doing something wrong?

I'm having horrible problems uploading my RAW files, captured with my 20D, using a cardreader. More often than not, Lightroom hangs after a dozen or two files, though more are imported than are actually displayed. Even when a "successful" import occurs, at least ten or fifteen files are ignored or rejected for reasons that are utterly unclear. I never have similar problems with Photoshop Bridge.
I'm running Windows XP with 2GB of RAM, an AMD Athlon 64 3400 Processor (2.2 GHz), NVidia GForce FX5500 graphics card, and an absurd amount of free space in my RAID array twin internal 250GB HD's and 320GB external drive. Courtesy of absurd problems with Roxio in the past, I've updated DirectX and all my drivers and UNinstalled and roll-back my OS to Windows MediaPlayer 10 (ver. 11 really screwed up my system, a problem lots of people, apparently, have encountered).
PLEASE HELP! I've read and heard so much positive feedback on Lightroom - but for me, the darn thing, thus far, has been a bit of a waste of money. Workflow tools aren't worth anything if the beginning of the proces - uploading images - is a huge problem.
Regards,
Bill

Is Lightroom able to accept and edit Nikon D4s RAW images?

A professional photographer from a nearby town said he heard Lightroom either did not or had difficulty working with Nikon D4s RAW images. I want to find out if this true or not.

Might have been true around the time the camera was launched but it usually only takes Adobe a few weeks to issue updates for new camera models.
As Bob says, the D4S has definitely been supported for a while now.

Working with RAW images without lens profile?

Does it make sense to work on RAW images if no lens profile exist for the used specific lens?
I see clear differences between RAW and JPG image in means of distortion.
How did you work with RAW images?

There are many advantages to using RAW, so yes it makes sense to work on RAW images even if no profile exists for the lens.
I see clear differences between RAW and JPG image in means of distortion.
How did you work with RAW images?
You can create your own lens profiles. Or you can manually adjust each image. Or you can set up presets for different focal lengths. There's a lot of ways to go.

MANAGING JPEG and RAW in PHOTOS OS X

I shoot in JPEG plus RAW. The files are imported OK to the Photos app and are shown as stacked. How do I DELETE several of the RAW images at once and RETAIN the JPEG version alone and thus save space on my drive.
Thanks

Thanks but that only works for RAW images imported using iPhoto. That is NOT working for stacked images imported to the photos app - for example today I took 6 JEPG+RAW images. They import OK and show as stacked with a J showing in the bottom left corner of the photo. If I do as you suggest and create the new smart album the new RAW photos don't show up - only the older RAW images imported using iPhoto.
Any other thoughts?

Editing RAW images

1.) Can RAW images be edited/color corrected in PS CS5? OR do you need to use Camera Raw from Bridge?
2.) For basic color correcting, is there an advantage to moving up to LightRoom?
Thanks.

1. Raw images can be opened by the Camera Plugin which can be accessed by Bridge or PS. Just open as smart object (raw files) or open as camera raw (will work on raw, tiff, jpg & PSD files) from PS.
2. I can't imagine any "basic" advantages in color correction (maybe in file organization, batching or interface), but I have virtually no experience with LR.

Olympus E500 RAW Image in Photoshop Elements 4.0

I am trying to find out if anyone has worked with the Olympus RAW Image (.orf) in Photoshop Elements. I downloaded the plug-in from the Olympus America site and installed it into Elements. Although the plug-in said that it was for Photoshop 5.0 or higher it loaded fine. However, when I open an image in Elements the interface is very basic and does not look at all like the Elements 4.0 interface. Thus I am wondering if anyone else has tried to use the Olympus RAW image with Photoshop and found a better plug in?
Alternatively is someone can give me some other input on how to edit these photos I would be appreciative.

You want to ditch that Olympus plug-in - i.e., take it out of the plug-ins
folder in Elements - and make sure you have the version of Adobe Camera Raw
which covers your camera. Once you find that, install it in place of the
one that shipped with Elements (probably 2.4) and your images ought to open
directly into ACR.
