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.

Yes, yes and yes. Its a good thing I kept Breezebrowser

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?

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?

EXIF data - e.g., Flash Exposure Compensation - is it hidden someplace?

I see in LR various pieces of EXIF data, but can't find FEC. Is it hidden someplace? Thanks.

Rob, this looks very good! Would any possible bugs in the code be limited to problems in searching on or viewing metadata, or does it have the potential of corrupting the LR database itself? From my limited understanding of the internals of how LR works, it seems to me that plugins would not be able to damage the LR database. Thanks!

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.

Flash exposure correction not show in Aperture 2 metadata view??

When using the nikon SB-600 flash exposure correction the information is stored in the NEF/RAW file, a read back in Nikon' View NX sofware is correct. However the read back in Apple' Aperture is always set to 0ev (which is not correct).
Any suggestion how to obtain the correct metadata? Use a plugin?

Problem Viewing Flash Exposure Data in Bridge

Hi Folks
When I view flash exposure data on my camera it will show me the flash compensation value I have set eg -0.7 or +2. When I download the images and view the metadata in Adobe Bridge (from CS3) I appear to lose this information. It will tell me that the flash fired or nor, but that is about it!
Is there anything I am missing here, or is it just a limitation of Adobe Bridge.
Any information would be gratefully received.
Regards

I have been looking for the same information in CS5. Although I can't find it displayed anywhere in the Camera Data you can find it if you really need to.
Choose File Info from the File menu and then go to the Raw Data tab. Use the search function to look for "FlashCompensation". I found it there for my Canon G11.
Painful but works if you really need it too.

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.

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).

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.

Missing Exposure EXIF Metadata After RAW Conversion

I am running Photoshop CS6 on a 64-bit Windows 7 PC. Since upgrading from CS5 I have noticed that the Exposure EXIF metadata as viewed in Bridge vanishes after RAW conversion/adjustment of my images. I've read at least one other posting to the forums describing a similar situation, however, I've not seen an acknowledgement of an issue or bug in Bridge. Clearing the RAW conversion settings restores the missing EXIF metadata.

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.

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.
