Exposure compensation in Lightroom

When I set exposure compensation to -2/3 stops in my Canon 5D II and import the files into Lightroom they are automatically corrected to normal after "render preview" is initiated when I look at the file. How do I stop this?
If I bracket photos in 1 stop increments, they all look the same after "render preview"
This does not happen when I look at the files in Bridge CS4

>Which one are you referring to?
It's in the preferences dialog in the presets panel. The fact that the button is greyed out indeed means it was applied. On the images it already happened to you should hit reset.

Viewing Metering Mode, Flash data, Exposure Compensation Values in Lightroom

Anyone know if it's possible to see the following data in Lightroom 2? I can view this data in the 3rd party tool Exifer (if I convert a pic to JPEG) but I think it would be very handy to see this in LR2. Anyone know how or if it's possible?
Focal point chosen
Metering Mode
Exposure Compensation Values
Flash data (Did or didn't the flash fire)
Shooting Mode (i.e. Manual, Av, Tv, P, etc)

Focal point is not possible. However, depending upon the camera model you should be able to see the others when the Exif metadata field preset is selected (see screnn shot below), and you should not have to convert to JPEG to do see Exif.

Where is the exposure compensation detail

I am looking for the exposure compensation detail in Lightroom 4.4 but cannot find it.

Well, you have to install it too ('Add' using Plugin Manager).

It takes some getting used to, but with practice, it is a very useful plugin indeed.
Worth noting: the plugin doesn't do anything you couldn't do yourself manually by editing .lrtemplate lua files (stored in 'Metadata Field Lists' folder in with Lightroom Presets) with a text editor - the plugin just makes it accessible to all users who can weild a mouse.
To be clear: you don't need a custom preset to see exposure bias, for example you can just select the built-in preset "EXIF". (exposure bias was omitted from the default preset for some reason).

Why is exposure compensation limited to +-4EV

I ran a quick test to determine whether exposure compensation worked better in the D7000 or in Lightroom. I started by taking one picture at ISO 1600 correctly exposed. I then reduced the ISO by half for the next 4 pictures ending with 100. I then loaded the pictures into LR 3.3 and adjusted the exposures of the pictures by 1, 2, 3 and 4 EV so they all ended up the same. If Lightroom was more efficient at exposure compensation the ISO 100 picture should be best. If the in-camera compensation is best the ISO 1600 should be best.
The first surprise was that the LR exposure compensation is limited to +-4EV.
The other surprise was that the ISO 100, 200, 400 and 800 pictures were indistiguishable. The ISO 1600 picture was the only one that looked different with both exposure and color being slightly off.
My tentative conclusion is that between ISO 100 and 800 LR and the in-camera are pretty much identical. At ISO 1600 (+4EV) LR is better, but that's a terribly narrow margin. You need 1-2 EV headroom to make adjustments.
I had hoped LR would have given mt a wider margin and, as it appears it would, superior compensation to the one implemented in the camera.
Yes, Yes, Yes, I know that it's probaably ACR doing it, but still!

When shooting in Camera RAW format you are retaining the full Analog to Digital (A/D) resolution, which today is 14 bits, or even 16 bits color depth (48 bits). When shooting JPEG the camera file output is limited to 8 bit color depth (24 bits). So even for 14 bit camera A/D converters we have:
This is not correct. jpeg files are gamma corrected while raw is a linear capture. Theoretically, a 8-bit jpeg in sRGB space can contain as much dynamic range as a raw file of any bit depth because of the tone curve. It breaks up quicker when you edit jpegs because you will start seeing posterization earlier because of the lower bit precision but the dynamic range is there to start with.
Jao xDL I appreciate the additional information and links you have provided, but it is probably more information (and some misinformation) than most of us can digest in one reading. Yes sRGB tone curve helps to "compress" a wider dynamic range" signal into the 24 bit JPEG space, but it still only contains 24 bits of information! My point is that when opening a Camera RAW file in LR we can use the camera's full A/D dynamic range for recovery of signal "beyond 24 bit JPEG." Today that is typically 14 bits or even 16 bits per color (42-48 bits), with even the cheapest cameras using 12 bit A/D. If JPEG has the same ability, then why are we capturing and using "larger" RAW files?
You also say:
At a fixed exposure, you actually will want to raise the ISO as far as you can to make sure you don't posterize shadow detail in the very deep shadows because of limited bit precision left over and to minimize the read noise contribution.
People use their expensive (and inexpensive) camera gear to shoot pictures, NOT run laboratory experiments! I don't want to change my ISO setting to get the best shadow details or use Auto ISO, except for very specific shooting situations. You are parsing technical semantics, gone way beyond the original question, and are now incorrectly restating what I already said:
The bottom line is that “best practice” is to expose for the maximum highlight value, even clipping highlights when you want to retain maximum noise-free shadow detail.
This is best left to use of 'Exposure Compensation' or 'Manual Exposure' settings, and review of image histogram on your camera. Just be aware that most camera histograms are a processed 24-bit sRGB JPEG representation. Your RAW file output will actually have significantly more "highlight" range than indicated! Do a Google search on ‘Rawnalyze.’ The author has sadly passed on, but you may be able to find a posted copy of the program.
The poster asked, "Why is LR Exposure limited to only ±4 EV." You can use the Tone Curve to increase the range as suggested by Lee Jay, but then you lose the other features it provides. In light of all the technical information everyone has presented, raising the Exposure range would be very useful.

N8 camera exposure compensation

N8 exposure compensation is not working.
setting exposure to +2 and after taking the photo there is no difference...
anyone has the same issue?

No, mine's working fine so there's something wrong with yours, have you installed the Anna Camera Update from Beta Labs?
If so try Restore Camera Settings option in Settings.
Next option, Battery Out reset (switch off then hold power button down for about 8 seconds until out vibrates).
Next option, try the Restore Factory Settings for the whole phone under phone management in Settings.
Last option, reinstall the Firmware using Nokia Suite or NSU then reinstall the Anna Camera Update.
If ail above fails take it to Nokia Care as if that's not working who knows what else is wrong.
Good luck because it really is a great Camera.

Adjusting Exposure Compensation Settings Of 808 To...

Apart from the inaccurate white balance of the Pureview 808 in low light which appears to be a permanent feature of the phone(still waiting for confirmation from Nokia whether there will be a software update to correct this), it seems that the exposure of the Pureview 808 can be manipulated or adjusted in Creative mode with the "Exposure Compensation" feature found on the left side of the screen. Since the image of the 808 is always over-exposed in low light, I guess this feature may come in handy. Has anybody used this "Exposure Compensation" feature when taking pictures in low light? Are there any guidelines on the usage of this feature? I have fiddled around with the settlings yesterday and found that in very low light situations where a brightly lit object is in a completely dark background, the Exposure Compensation needs to be at -0.7 or -1.0 for a satisfactory image to appear. At 0 or -0.3, the image will become too bright and blurry. The ISO plays a part as well in these low light conditions as a minimum ISO400 is required for these low light shots.
I would appreciate some information or guidelines on the usage of the "Exposure Compensation" settings of the Pureview 808 in low light. At least the exposure can still be adjusted manually for a more usable image, unlike the white balance issue which seems to be a fixed or inherent thing in the 808(hopefully not perenially).
Thanks.

Try checking this and see if this helps you in any way: Nokia 808 PureView Tips, Tricks and Photography.
Another thing, one of our friends here posted a thread that there's a new update available for the said device so you may also want to check if the update is already available for your precious one. See here. Please take note though that update availability depends on the existing firmware version, operator and variant.
Checking Discussions Guidelines once in a while will not hurt.
Thanks for the information. Much appreciated. The latest update that I have on my 808 is software version 113.010.1507. The latest update (113.010.1508) is still not available yet at where I live.
THanks for the link on the Pureview tips and tricks. Will check on it in a while.

Flash Exposure Compensation Metadata

Please allow Bridge to read and state the degree of Flash Exposure Compensation that a photo uses in its metadata. Currently, Bridge does not read this info for Canon photos but the info is in the picture.

Flash Exposure Compensation Value Not Displaying in EXIF Info

When adjusting Flash Exposure Compensation on Nikon D4 camera (not on the Speedlight) the set value is not showing in EXIF Field in Aperture 3.4.1. It always shows as a 0 value regardless of camera setting. When I open the .nef in Nikon View NX (v2.2.4) the set value for Flash Exposure Compensation is accurately shown in the EXIF info. Have tried editing the Aperture EXIF fields (removing Flash Exp Comp and re-entering it) but, to no avail. Has anyone seen this, or know of a solution? Are any D800 users seeing the same thing?
Thanks!

Greg,
All the references to the element "rdf:value" in the XMP Specification
Part 1 appear in discussions about the implementation of XMP Qualifiers.
Page 21,
The presence of property qualifiers is indicated by a special use of
the rdf:Description element. Each rdf:li array item in the example
contains an rdf:Description element, which itself contains the
following:
-- a special element called rdf:value that represents the value of
the property
-- zero or more other elements that represent qualifiers of the value.
In this case, there is one property qualifier called ns:role.
Page 26
Other qualifiers cause the RDF for the qualified property to look like
a struct with a special rdf:value field. The presence of rdf:value is
what denotes this as a qualified property.
Page 28
For qualifiers other than xml:lang, RDF forces the qualified property
to look like a struct with a special rdf:value field that contains the
actual value from the XMP Data Model. The other fields of the fake
struct are the qualifiers. The presence of rdf:value is what
distinguishes a real struct from a qualified property.
I assume that you are not trying to implement XMP qualifiers. Perhaps
you should use vra:value instead?

600EX Flash - 5D III. Flash exposure compensation.

How can I set the FLASH exposure compensation from the CAMERA. It appears that I have to set the exposure compensation on the back of the flash unit. I would like be able to change the FLASH EC settings from the camera, not the flash unit.
Solved!
Go to Solution.

Ok, I have my 5D III out with my 600EX-RT mounted.
Let's make sure you don't have terminology confused.
There are two different compensations... there's "explosure compensation" and "flash exposure compensation".
If you meter exposure with the camera and then use the rear dial (assuming you did not disable it) after waking up the metering system then the rear dial will change the "exposure" compensation (this changes the metering for the AMBIENT light reading that the camera reads -- ignoring the flash). So changing "exposure compensation" will not change the flash even if the flash is powered on and connected. It would only change the camera.
On the top of the camera, just in front of the top LCD screen, there are four buttons. One has a dimple on it. That button is the ISO & "flash exposure compensation" button. If you press that button, then the rear LCD screen should show you that the rear dial will control "Flash exposure comp." Turning the rear dial at that point will make the adjustment show initially ONLY on the camera LCD screen... UNTIL you press the 'Set' button in the middle of the dial. Once you do that, the rear LCD screen on the flash will show that you have the flash exposure compensation enabled (it will ONLY show this when you wake up the metering system... if the metering system is allowed to go inactive the flash will only display the netural compensation... but as soon as you re-activate metering it will display your exposure compenation as set on the camera.
Also... on the rear LCD screen there's a box just below the ISO setting that shows if you have flash exposure compensation set and the amount.
This is all being controlled only by the camera -- I'm not using the menu buttons on the flash itself.
IF I DO use the buttons on the flash to set flash exposure compensation then the camera is locked out. It will report what compensation has been set on the flash, but will not let me change it until I use the buttons on the flash to return it to 0.
Does that help and are you able to do this with your flash?

Smart Album tracking Exposure Compensation?

In iPhoto '09 it's very easy to make a Smart Album that shows all your photos that have an ISO of 800, or a Smart Album that shows all your photos taken with a flash.
But is it possible to make a Smart Album that uses the Exposure Compensation (e.g −1 EV) as its criteria? I can't see any way of doing it.

No there isn’t. You’re limited to the items in the Drop down menus.

Suggestion: Exposure Compensation

Suggestion for software update: Exposure compensation via the volume up/down button. The pics I take are amazingly good for such small lens and compact device, but the ability to compensate for those backlit situations would be excellent. How hard could it be?

Probably wouldn't be hard. The chips probably already have the feature. But it would destroy the utter simplicity. When I shoot people, I move or move them so they're not backlit. Backlit subjects tend to look noisy and in unkind light when you increase the exposure.

Flash Exposure Compensation

I am shooting RAW files with a Nikon D200 and SB-800 Flash. I use controls on SB-800 to adjust flash exposure compensation. When photos are imported into Aperture the flash metadata states "strobe return light detected". The flash exposure compensation field lists zero despite having set an exposure compensation on the flash. Any ideas?

Exposure problem with Lightroom 4 CS5 and Raw 6.7

Hi all
I have recently upgraded from Lightroom 3.6 to the new Lightroom 4 and am genrally pretty happy with it, I tend to use it along with photoshop CS5 extended and also imagenomic Portraiture, but I have found an annoying little problem in doing this and something that I never suffered with when using Lightroom 3.6 and it is this...
when I take an image from Lightroom 4 and click Edit image in Photoshop CS5 and then use Imageonmic to soften skin etc all seems to work well I then carry out any touching up within Photoshop and once finished save it back to lightroom for any final tweaks etc which is fine and all works smoothly, except once I have saved it back to Lightroom the exposure has been pushed up about 3-4 stops at least , meaning I then have to pull it down again and this can sometimes result in extra editing I could do with out. now I know its not the end of the world and is probably just a bug that I'm hoping will be sorted within Lightroom 4 but I just wondered if anyone else has had a similar problem, is it a bug or am I doing something wrong? (although I'm doing the same with Lighroom 4 as i used to do with LIghtroom 3.6 and that worked fine)
Oh one more thing I should mention to get lightroom 4 and CS5 to work properly together I had to go into the Adobe Labs site and download the Camera RAW 6.7 software for CS5 so it could also be a bug here i guess.

There have been several posts over on the Lightroom forum, and other non-Adobe forums also, about this issue: it seems that there's a bug in ACR 6.7RC which causes the image to be over-expose, compared with the setting applied using PV2012 in LR. I guess this is the kind of thing a Release Candidate is supposed to flag up! I was all set to upgrade my own ACR to ensure that PS would recognise my LR4 edits (I normally avoid RC versions and wait for the final), but all the reports of this problem have stopped me from doing so.
In the meantime, best option so far as I'm aware is to process the image in LR (you get the option when you choose to edit in PS), meaning that it does all the rendering before passing it over to PS (otherwise, ACR handles the conversion of the raw file into TIFF). This does however mean that smart-objects and so on are temporarily out of the equation.
I'm sure this will all be resolved pretty soon.
Edit: in fact, one of the posts I mentioned is about ten posts down in this very forum: http://forums.adobe.com/thread/974963?tstart=0

Can I create a doulbe exposure photo in lightroom 5?

I am trying to start a new project in lightroom, I need to create a double exposure to some of my photo's. I am fairly new to lightroom and need to know if this is possible.
Thanks for any advice.
Ki

Yes you can create virtual copies from a single image, with different exposures for export to Photoshop or HDR software such as photomatix. See this link:

Exposure - Photoshop vs Lightroom

Hi,
I have the following problem:
On the right side I have a camera raw image opened in Lightroom and the only adjustment is the exposure which is raised by 2 stops.
On the left side the same image opened in Photoshop, using ACR, all settings default (so no adjustments at import, but the image is imported as 16 bits). Then, using the exposure adjustment (under Image menu) I raised the exposure by 2 stops, like in Lightroom.
The difference is that in Lightroom all the details in highlights are retained, whereas in Photoshop are clipped.
I was under the impression that if you import a raw image as 16 bits it will retain all the full dynamic range, or is something I'm doing wrong?
Full res snapshot here:
http://www.lightdimension.ro/poze/screenshot.jpg
Original camera raw image here:
http://www.lightdimension.ro/poze/Nori_Ranca.396.CR2

Lightrooom has more data available from RAW files, and does some highlight recovery.
Photoshop doesn't have the extra RAW data, and doesn't do highlight recovery.
Technically, what Lightroom does isn't just exposure adjustment - because it automatically includes highlight recovery.
